Abstract:
The purpose of this non-experimental, quantitative descriptive study was to identify the holistic health educational needs of middle aged men and to consider nursing interventions. Between the ages of forty to sixty years, physical illness can coincide with a cluster of social changes as well as the normal developmental mid-life review. This can result in a prolonged period of physical and emotional stress (Berger, 1994). Mortality statistics demonstrate that, in comparison to women, men in the 25 to 64 age group have higher rates of suicide, motor vehicle accidents, work place injuries, ischaemic heart disease, non gender specific cancers, and alcohol consumption than women. With a disease oriented health system. the total health care needs of men which include prevention and maintenance of health, -appear not to be currently addressed (Pearson, 1993). A convenience sample of seventy Caucasian men aged 40 ~ 60 years living in a metropolitan area fanned the study group. All participants completed the National Wellness Institute, Wisconsin, USA, Lifestyle Assessment Questionnaire. This comprehensive educational/assessment tool holistically examined lifestyle, wellness behaviours, and health risk status. Analysis of the group report has provided indicators of the health educational needs of this group. Knowledge deficits and health topics of interest have been identified. Recommendations include the need for health professionals to be educated, so that they understand the complex sociological, psychological and political variables that influence men's ability to seek, obtain and maintain health at different age differentials. In addition, further research in to the development of gender and age specific health educational materials and programmes is recommended.

Full text
Abstract:
Decreased testosterone levels (hypogonadism) in middle-aged men (aged 45-64) has been associated with increased levels of depression. Studies have suggested that increases in anxiety and/or attention problems may also be associated with hypogonadism but have not provided empirical evidence to support these suggestions. The purpose of this quantitative study was to examine depression, anxiety, and attention problems in middle-aged men using a psychological self-report inventory. The theoretical model used in this study was the biomedical model, which combined pharmacological treatment with psychological self-report inventories to determine if there was an association or relationship between the testosterone levels in men and the psychological distress experienced by men who have become hypogonadal. A total of 179 males were recruited through local physicians. There was a statistically significant difference and a small size effect in the level of depression, anxiety, and/or attention issues experienced by those who were receiving TRT versus those who were not. This study may provide some guidance to medical clinicians, such as psychiatrists, primary-care physicians, and endocrinologists, as well as clinical psychologists who see middle-aged men in their practice settings.

Abstract:
Research into transitions which explore the personal changes of those undergoing them, especially men, are still rare, particularly in regards to a changing sense of self and life world. Research into the movement of men out of hierarchy, the dominant structures of work institutions in the western world, is rarer still. Using hermeneutic and phenomenological frameworks, this study tracks the journeys of six men by in-depth interviews and discussions as they move out of hierarchical structures to recreate their work and, in varying degrees, themselves. As a means of looking beyond events, and for their metaphoric and philosophic perspectives, the Hero and Phoenix myths are used to further explore levels of meaning identified within the transition processes. Drawing on the work of Jung, Bridges, Neville, Campbell, O’Connor and Gareth Hill, the six stages into which I have organised the transitions are compared to the six key phases of the Phoenix myth. A Jungian framework informs the interpretation of the underlying significances demonstrated in the men’s processes of regeneration. The men’s individual responses to their transitions are also identified and described, from subjective and proactive perspectives. Changes in the men’s self perceptions and their changing relationships to authority, brought about by their shifting loci of control, are documented. Analysis of the stages most likely to be suitable for proactive intervention (as conscious or organised responses to the process), are indicated. Primary and secondary preconditions for successful transitions out of hierarchies are postulated. The men’s self-reflections illuminate experiences of uncertainty and clarity, confidence and exploration, compartmentalisation and synthesis. The role of an ‘inner voice’ (an unchanging core identity) and their changing relationship with these aspects of Self, is articulated as critical factors in the men’s ‘successful’ transitions. Integral to this research is the concept that the power of an individual’s experience can inform those who share a similar experience. Therefore applications of the research, and strategies to manage and facilitate transitions out of hierarchical environments, are suggested. This thesis is written in support of my hypothesis that transitions can be mapped; that they are journeys on several levels of personal and practical transformation; and that to proactively engage with transition processes requires not only an understanding of the stages of the process itself, but also an understanding that changes in self-perception and self-relationship will also occur for those undergoing them.

Chessum, Thierry. "Graphic interrogation in psychosocial research : Deleuze and comics and middle-aged men." Thesis, Open University, 2015. http://oro.open.ac.uk/47773/.

Full text
Abstract:
The assemblage of comics, Deleuzian metaphysics and middle-aged men in the context of psychosocial research is an experiment in the sense that Deleuze advocates for the furtherance of thought. The works of Deleuze and Deleuze and Guattari can allow us, it is suggested, to bring together theoretical problems in comics theory with theoretical problems in psychosocial research and provide us with new insights as to how we might look at visual data qualitatively from participants who agreed to recount episodes of their relationships in graphic narrative form. Both psychosocial qualitative research and comics theory are new and fast moving fields which offer scope for creative thinking. It is argued in this thesis that the ‘affective’ and ‘visual’ turns, which are having an important impact in the social sciences, corresponds to the expressive function of comics, specially in the autobiographical, memoir and confessional genre. Having set the theoretical lens with the work of Deleuze and Guattari and some of their commentators, examples from commercially published works are examined in order to relate theory to empirical examination, prior to considering the work submitted by participants. Lastly, interspersed throughout the text and together as an appendix, I offer my own visual reflections in the comics mode which I believe dialogue with topics in the text, whilst remaining separate activities. That is to say I consciously avoid text or comic being an illustration of one another.

Abstract:
Primary hyperparathyroidism (PHPT) is a common endocrine disease, existing in both genders and in all age groups. Postmenopausal women are at particular risk of developing the disease and estrogen decline after menopause is suggested to affect the progress. Although PHPT is mild in its presentation with subtle or no subjective symptoms, it is associated with an increased risk of associated morbidity and also mortality i.e cardiovascular complications, psychiatric instability, concomitant metabolic abnormalities, obesity and decrease in bone mineral density. The current cure is surgical removal of the diseased gland/s, but other medical alternatives have been investigated. The disease is thoroughly explored in postmenopausal women but less is known about other populations groups. Since progression of the disease generally is slow, the underlying disturbance of the calcium homeostasis can be suspected to have been established a long time prior to diagnose with potential to affect associated morbidity. The general aim of this thesis is to clarify the expression of PHPT in premenopausal women and in elderly men and to explore how frequent the disease in these populations occurs. The women and men were investigated through population-based studies. Baseline data and prevalence of PHPT in premenopausal women age 40-50 years were studied (Paper I), the prevalence was 5.1% in this population and was associated with decreased bone mineral density and associated obesity. In a three years follow up of the female cohort, the effects of menopausal transition and associated morbidity was investigated (Paper II). The prevalence and expression of PHPT in men between 69 and 81 years and impact on bone mineral density, physical performance, fall and fracture prevalence was explored through data from Mr Os Sweden (Papers III and IV). In this population prevalence of PHPT was 0.73% and associated with lower bone mineral density and inferior physical performance.

Full text
Abstract:
In 2010, men who have sex with men (MSM) represented 4% of the population in the United States (US) and accounted for 78% of all new Human Immunodeficiency Virus (HIV) infections among Hispanic men. Hispanic men who have sex with men (HMSM) accounted for the third largest number of new HIV infections (6,700 cases). This dissertation explored the effects of age, loneliness, substance use, depression, and social support on high risk sexual behaviors that predispose middle aged HMSM to sexually transmitted infections (STIs) and HIV infection risk. A sample of 150 urban HMSM aged 40 to 65 were surveyed in this study. Singer’s Syndemics Theory (1996) provided this study’s theoretical framework. Data was analyzed using a variety of parametric and non-parametric statistics. Loneliness, social support, depressive symptoms, alcohol/drug use, and sexual risk behaviors were found to have an influence on HIV infection status in this study. Partner status, religious affiliation and age did have an influence on alcohol use in this study’s participants. Also, participants with increased age had increased depressive symptoms in this study. Lastly, depressive symptoms, substance use, social support, and loneliness did have an influence on sexual risk behaviors in this study’s participants, specifically alcohol use and illicit drug use. The findings from this study should be used to assess, diagnose, plan, implement and evaluate prevention strategies geared to reduce STI and HIV infection in this population. Future research should build on these findings and develop tailored risk reduction interventions addressing HMSM, with particular attention to the understudied age group of the middle aged HMSM.

Full text
Abstract:
Background: Queensland men aged 50 years and older are at high risk for melanoma. Early detection via skin self examination (SSE) (particularly whole-body SSE) followed by presentation to a doctor with suspicious lesions, may decrease morbidity and mortality from melanoma. Prevalence of whole-body SSE (wbSSE) is lower in Queensland older men compared to other population subgroups. With the exception of the present study no previous research has investigated the determinants of wbSSE in older men, or interventions to increase the behaviour in this population. Furthermore, although past SSE intervention studies for other populations have cited health behaviour models in the development of interventions, no study has tested these models in full. The Skin Awareness Study: A recent randomised trial, called the Skin Awareness Study, tested the impact of a video-delivered intervention compared to written materials alone on wbSSE in men aged 50 years or older (n=930). Men were recruited from the general population and interviewed over the telephone at baseline and 13 months. The proportion of men who reported wbSSE rose from 10% to 31% in the control group, and from 11% to 36% in the intervention group. Current research: The current research was a secondary analysis of data collected for the Skin Awareness Study. The objectives were as follows: • To describe how men who did not take up any SSE during the study period differed from those who did take up examining their skin. • To determine whether the intervention program was successful in affecting the constructs of the Health Belief Model it was aimed at (self-efficacy, perceived threat, and outcome expectations); and whether this in turn influenced wbSSE. • To determine whether the Health Action Process Approach (HAPA) was a better predictor of wbSSE behaviour compared to the Health Belief Model (HBM). Methods: For objective 1, men who did not report any past SSE at baseline (n=308) were categorised as having ‘taken up SSE’ (reported SSE at study end) or ‘resisted SSE’ (reported no SSE at study end). Bivariate logistic regression, followed by multivariable regression, investigated the association between participant characteristics measured at baseline and resisting SSE. For objective 2 proxy measures of self-efficacy, perceived threat, and outcome expectations were selected. To determine whether these mediated the effect of the intervention on the outcome, a mediator analysis was performed with all participants who completed interviews at both time points (n=830) following the Baron and Kenny approach, modified for use with structural equation modelling (SEM). For objective 3, control group participants only were included (n=410). Proxy measures of all HBM and HAPA constructs were selected and SEM was used to build up models and test the significance of each hypothesised pathway. A likelihood ratio test compared the HAPA to the HBM. Results: Amongst men who did not report any SSE at baseline, 27% did not take up any SSE by the end of the study. In multivariable analyses, resisting SSE was associated with having more freckly skin (p=0.027); being unsure about the statement ‘if I saw something suspicious on my skin, I’d go to the doctor straight away’ (p=0.028); not intending to perform SSE (p=0.015), having lower SSE self-efficacy (p<0.001), and having no recommendation for SSE from a doctor (p=0.002). In the mediator analysis none of the tested variables mediated the relationship between the intervention and wbSSE. In regards to health behaviour models, the HBM did not predict wbSSE well overall. Only the construct of self-efficacy was a significant predictor of future wbSSE (p=0.001), while neither perceived threat (p=0.584) nor outcome expectations (p=0.220) were. By contrast, when the HAPA constructs were added, all three HBM variables predicted intention to perform SSE, which in turn predicted future behaviour (p=0.015). The HAPA construct of volitional self-efficacy was also associated with wbSSE (p=0.046). The HAPA was a significantly better model compared to the HBM (p<0.001). Limitations: Items selected to measure HBM and HAPA model constructs for objectives 2 and 3 may not have accurately reflected each construct. Conclusions: This research added to the evidence base on how best to target interventions to older men; and on the appropriateness of particular health behaviour models to guide interventions. Findings indicate that to overcome resistance those men with more negative pre-existing attitudes to SSE (not intending to do it, lower initial self-efficacy) may need to be targeted with more intensive interventions in the future. Involving general practitioners in recommending SSE to their patients in this population, alongside disseminating an intervention, may increase its success. Comparison of the HBM and HAPA showed that while two of the three HBM variables examined did not directly predict future wbSSE, all three were associated with intention to self-examine skin. This suggests that in this population, intervening on these variables may increase intention to examine skin, but not necessarily the behaviour itself. Future interventions could potentially focus on increasing both the motivational variables of perceived threat and outcome expectations as well as a combination of both action and volitional self-efficacy; with the aim of increasing intention as well as its translation to taking up and maintaining regular wbSSE.

Abstract:
This study investigates the poor mental health of unemployed middle-aged men (with women as a reference for comparison) in Hong Kong, who were unemployed and isolated socially in what is officially described as a new town, Tin Shui Wai. The study also explores the different aspects of social capital that may improve mental health for middle-aged individuals, drawing on data from ten in-depth interviews with five men and five women, two focus groups with five men and six women and a survey using questionnaires completed by 188 men and 215 women. The results showed that men in the sample had poorer mental health than women. In particular, levels of depression and alcohol abuse were higher in the men than the women. By contrast, women in the sample manifested more anxiety than the men. The findings also showed that unemployment had more negative effects on men than on women, with the men having more free time but nothing to do, feeling stressed, going out less with family members, drinking more alcohol and so on. Drawing on theories of social capital (Lin et al. 1985, McKenzie 2006), I argue that the poor mental health among men was associated with weak social capital. The data showed that for both men and women, social capital could have a positive association with reducing depression and anxiety. In particular, for men, community networks and social support had a positive association with reducing depression and alcohol abuse. For women, group membership, community networks and social cohesion had a positive association with reducing depression and anxiety. Based on these findings, I suggest an approach that focuses on increasing social capital to promote mental health among men and women. The approach argues for the need to introduce policies and strategies to promote social capital at the community and individual level for men, and at the community level for women.

Abstract:
The purpose of this study was to compare selected kinematic characteristics of distance runners over a twenty year period. The subjects in the investigation were 14 long distance runners who at the time of the first observation were considered highly trained (running more than 50 miles per week). The second observation occurred approximately 20-23 years after the first observation. At this time the average weekly mileage per runner had decreased to 37 miles per week. The first observation's data were collected with a Locam camera at film speeds ranging from 60 to 120 frames/second. The film data were digitized at the same time as the second observation's data. The second observation's data were collected with a Panasonic 5000 shutter video camera. The Peak Performance Motion Measurement System video interface allowed a 60 frame/second field rate. Ten subjects ran at a speed of 3.4 m/s; two subjects at the speeds of 3.1 and 3.6 m/s; and one subject at each of the following speeds: 4.0, 4.5, and 4.9 m/s. Statistical analyses (ANOVA) of the stride length, stride frequency, support and non-support time, and joint angular displacement indicated no significant difference (p > .05) between the first observation and the second observation. The results of this study indicated that the kinematics of continually active long distance runners do not change with an increase in age.

Abstract:
While short-term (~six weeks) HIIT induces rapid increases in skeletal muscle oxidative capacity, the anabolic potential of HIIT for promoting concurrent gains in skeletal muscle mass has received less scientific inquiry. The experiments undertaken for this thesis investigated skeletal muscle adaptive responses following HIIT, resistance exercise training (RET) and endurance exercise training (ENT), and after a subsequent period of detraining, in sedentary, middle-aged men. Thirty-five sedentary, males (39±3 y) performed six weeks of either ENT (n=12), HIIT (n=12) or RET (n=11) followed by 2.5 weeks of detraining. Skeletal muscle gene and protein expression, muscle fiber characteristics, body composition, muscle thickness, muscle strength, aerobic capacity, resting metabolic rate and glucose control were assessed at baseline, and after exercise training and detraining. Lean mass increased after RET and HIIT (+3.2±1.6% and +1.6±2.1%, P<0.05). Muscle strength (sum of leg press, leg extension and bench press 1RMs) increased after all exercise training interventions (RET: +25±5%; HIIT: +10±5%; ENT: +7±7%, P<0.05). Aerobic capacity increased only after HIIT and ENT (+14±7% and +11±11%, P<0.05). Type I and II muscle fiber size increased for all groups after exercise training and remained elevated after detraining (main effect of time, P<0.05). Following detraining, the gains in lean mass and muscle strength were maintained in RET and HIIT groups, but maximal aerobic capacity declined below post-exercise training levels in HIIT and ENT (P<0.05). Androgen receptor, Akt and mTOR total protein increased after exercise training in all groups. Vitamin D receptor and apelin receptor mRNA increased after exercise training in all groups (main effect of time, P<0.05). Six weeks of HIIT resulted in the most pronounced skeletal muscle adaptation prior to detraining in middle-aged men. While only HIIT and RET resulted in increases in lean mass and muscle thickness, gene and protein expression of markers implicated in muscle growth responses were largely similar across all exercise training modes. Short-term detraining did not negatively impact gains in muscle size, mass or strength irrespective of exercise modality.

Abstract:
Background & Aim: Osteoporosis is an important clinical and public health problem through its association with age-related fractures. Compared to women, much less is known about what factors determine age-related bone loss in men. The aim of the work presented in this thesis was to examine the impact of the main steroid hormones, (sex hormones & vitamin D), lifestyle factors and prior fracture on bone health in middle age and elderly men in Europe. Methods: Data presented in this thesis was derived from two large multicentre observational studies: the European Male Ageing Study (EMAS) and the European Prospective Osteoporosis Study (EPOS). In EMAS 3,369 men aged between 40 and 79 years were recruited from 8 European centres for participation in a study of male ageing. They completed a postal questionnaire which included questions concerning lifestyle and were invited to attend for quantitative ultrasound (QUS) of the heel, from which the parameters broadband ultrasound attenuation (BUA) and speed of sound (SOS) were obtained, a questionnaire including measures of physical activity, assessment of physical performance and a fasting blood sample from which the bone markers serum N-terminal propeptide of type 1 procollagen (P1NP) and crosslinks (β-cTX), total testosterone (T), total oestradiol (E2) and sex hormone-binding globulin (SHBG), 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D) were measured. Dual energy x-ray absorptiometry (DXA) of the hip and lumbar spine and peripheral quantitative computed tomography (pQCT) of the radius at the distal (4%) and midshaft (50%) sites was performed in a subset of two centres. In EPOS, 6,656 men and 7,203 women aged 50 years and over were recruited from population registers in 32 centres. Subjects completed an interviewer administered questionnaire that included questions about previous fractures. Subjects were followed prospectively for a median of 4 years to determine the new occurrence of fractures. A subsample of subjects had bone mineral density measurements performed. Key Results: Based on data from EMAS, free T and both free and total E2 were positively related to the QUS parameters BUA and SOS, while SHBG concentrations were negatively associated. Total and free E2 were negatively associated with β-cTX though not P1NP while PTH was positively associated with both β-cTX and P1NP. Higher levels of both bone markers were significantly associated with lower QUS parameters and lower DXA-assessed bone density at the total hip and lumbar spine. 25(OH)D was negatively while 1,25(OH)2D positively associated with bone parameters. Higher levels of physical activity and lower physical performance were associated with both higher BUA and SOS. Smoking was associated with lower QUS parameters, while there was a U shaped association with frequency of alcohol consumption. A recalled history of any childhood fracture or forearm fracture was not associated with either bone mass in later life or an increased risk of fracture in men as well as women. Conclusion: Steroid hormones, particularly oestrogen & vitamin D are associated with bone health in middle age and older men. Modification of lifestyle, including increasing physical activity and stopping smoking may help optimise bone strength and reduce the risk of fracture in men. In assessment of future fracture risk a history of childhood fracture does not appear to be important.

Abstract:
The physiological responses of negative work involving predominantly eccentric muscle contraction were compared to positive work involving predominantly concentric muscle contraction in twelve older healthy subjects between 39 and G5 years of age. A motorized cycle ergometer was used for steady state exercise testing. To study the physiological response to positive and negative work, pedalling frequencies of 35, 55, and 75 rpm and a constant power output of 60 Watts were chosen. Steady state values of oxygen consumption (VO2), heart rate (HR), minute ventilation (VE), tidal volume 0.05). The greater VO2 (1.14±.0.13 and 0.62±0.15 1/min (mean+standard deviation) during positive and negative work respectively), HR (95. 8±.10. 7 and 81.8 ± 13.6 bpm) and VE (26.7±5.5 and 16.5±5.2 1/min) during positive work were consistent with the greater energy efficiency of negative work. The greater VE during positive work reflected a greater VT (1.46±.32 1/br) than negative work (0.99±.31 1/br) while fb was the same (18.7±.4.0 and 17.5±5.6 br/min) for both positive and negative work. During positive work, all physiolgical variables were greatest at 75 compared to 35 and 55 rpm (p<0.05) except for fb which showed no significant difference across the three pedalling frequencies

0.05). During negative work, VO2 and HR were greatest at 75 and 35 rpm compared to 55 rpm 0.05). The slopes and intercepts of the regression lines relating HR and VO2, VE and VO2, VT and VE, and fb and VE were identical between positive and negative work except for a higher intercept for the VE and VO2 relationship during negative work. Thus, it was concluded that at a power output of 60 Watts, physiological responses such as VO2, HR and VE during positive and negative work were qualitatively similar. When changes in VT and fb were compared from baseline to steady-state for positive work, however, VT and fb both increased. In contrast, for negative work, VT increased minimally while relatively greater increases in fb were observed for pedalling frequencies of 35 and 55 rpm. The relatively greater effect of negative work on fb compared with positive work is not predicted from the known ventilatory responses to low intensity exercise. Further study is needed to elucidate the precise mechanism for this predominant increase in fb during negative work.

Abstract:
The study seeks to answer how midlife gay men in Manchester manage growing older. It analyses accounts generated through in-depth interviews with 27 middle-aged gay men living in Greater Manchester (aged 39 - 61) and 20 participant observation sessions conducted in Manchester's 'gay village.' It deploys an interpretivist methodology and a 'pick and mix' analytical framework developed by Thomson (2009) that uses of Foucault's 'technologies of the self' (1987) (that concern capacities for agency) but located within 'fields of existence' (with their own norms) adopted from Bourdieu (1984). Through analysis of participants' accounts of bodily practices (dress, grooming, diet, exercise) and their relationships in various fields, the study examines the constraints on and choices around expression of midlife identity and ways of relating. The study's structuring theme concerns the mechanisms through which midlife gay men in Manchester differentiate themselves from others. Differentiation is achieved largely through moral and epistemic claims-making around an 'authentic' gay male midlife self that is central to the notion of a legitimate, (age-appropriate) form of socio-sexual citizenship. As extant scholarship has identified, there are normative restrictions on expression of a midlife self and the possibilities for interaction (especially with younger gay men) but men can use self-worth and political knowledges gained from life experience ('ageing capital' and age-related technologies of the self) to do other than comply with such restrictions. But, this study also illuminates men's ambivalent responses to age, ageing, gay ageism and homophobia that involve negotiation with discourses that inform understandings of ageing and sexuality. The study also maps a cultural "politics of the minor" (Rose 1999) operating at the micro-level, which is concerned to affect the context of interaction. The power relations of gay male ageism that are crucial to this expression of politics are multidirectional. Midlife gay men are not just the targets of ageism from younger gay men. They distinguish themselves in ways that can express ageism towards younger, (some) peer aged and old gay men. The study also complicates assumptions about midlife gay men and their lives: 1) Dressing for 'comfort' (part of an 'authentic' midlife self) contradicts the idea that midlife gay men obsess about the body, prolonging youth and maintaining sexual marketability. 2) Manchester's gay village is not overwhelmingly a site of exclusion for midlife gay men. They negotiate with the rules of the game and use emotional and cultural political knowledges gained through life experience to resist ageism and carve out a conviviality that involves friendship, affection and care for others in sexualised space. 3) Gay men continue to experience unequal access to public space but gains in self-worth with age and the recent tolerance dividend indicate that this is now more often experienced as safer. Gayness is now being claimed as integral to broader sexual citizenship. 4) Midlife gay men do not live outside of kinship. Subjects creatively reconfigured their kinship circles/friendship families over time. This form of kinship has special political significance for this present generation of middle-aged gay men in Manchester. Paul Simpson, Manchester University, PhD. Sociology. 11 September 2011.

Abstract:
While a great deal of research has been directed towards investigating the age-related decline in V02max, the effect of physical activity on the age-related decline in V02max has not been clearly established. Therefore, the purpose of this study was to examine the relationship between physical activity and the age-related decline in maximal oxygen consumption (VO2max) in apparently healthy individuals. In order to assess the effects of physical activity on the age-related decline in V02max, physiological data was obtained from 142 former participants (116 men and 26 women) (40 ± 8.0 years), in the Ball State University Adult Physical Fitness Program across an average of 12 ± 4.5 years. The subjects were divided into three physical activity group categories depending on their self-reported physical activity status at the time of the first and follow-up test. Those subjects who were sedentary at the first and last test were designated as SED-SED. Those who reported sedentary at the first test and active at the last test were designated as SEDACT and those who were physically active at the time of both tests were designated as ACT-ACT. The data from the analysis revealed that the rate of decline in V02mx expressed as change per year among adult men varied as a function of their reportedphysical activity habits. Those men designated as SED-SED and ACT-ACT experienced a statistically significant decline (p<0.05) in V02max during the follow-up period, while, those men designated as SED-ACT maintained their V°2max. The rates of the change in V02max (ml-kg- 1•min-1) for the men were -0.45, 0.03 and -0.22 ml•kg-l-min-1•yr1 for the SED-SED, SED-ACT and ACT-ACT groups respectively. The percent decline in V02max were 6%, 11% and 2% respectively. A statistical comparison of the rate of change among physical activity groups indicated a difference between the SED-SED and SED-ACT groups (p<0.05). Within the limitations of this study, these data suggested that there was no statistically significant difference in the rate of change in V02max (ml•kg-1•min-1-yr1) between the SED-SED and ACT-ACT physical activity groups. However, when presented as percent change per decade, the decline for those men who were sedentary at both time points was twice that of those men who reported an active lifestyle at both time points. Although the rates of change were not different for the SED-SED and ACT-ACT physical activity groups, those men with a physically active lifestyle maintained their aerobic power advantage as compared to sedentary men who remained sedentary. Furthermore, sedentary men who took up an active lifestyle had offset the decline in V02max (ml•kg-1•min-1) attributed to physical inactivity.The rates for the change in V02max (ml•kg-1•min-1-yr1) for the women were -0.36, 0.20 and -0.21 (ml•kg-1•min-1-yr1) for the SED-SED, SED-ACT and ACT-ACT groups respectively. While these changes were similar in direction and magnitude to those observed for the men, there were no statistically significant differences among the female groups (p>0.05). Therefore the results from the present study were inconclusive for women possibly due to the low sample size (n=26).

Doctoral thesis, Uppsala University, Department of Public Health and Caring Sciences, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-7210.

Abstract:

The aim was to contribute to the optimal use of the resting ECG by exploring, in middle-aged and elderly men, the development and regression of ECG abnormalities; the prognostic value of the ECG for cardiovascular disease compared to conventional risk factors; and the impact of age at baseline and follow-up time for prediction of cardiovascular disease.

It was based on the Uppsala Study of Adult Men cohort that was started in 1970. Participants were examined at ages 50, 70, 77, and 82, with annual updates on mortality and in-hospital morbidity using national registries.

The studies indicated that the prevalence of silent MI and frequency of regression of major Q/QS patterns may be higher than previously believed. Considering that persistent T wave abnormalities and ST segment depression carried twice as high a risk for future cardiovascular disease (CVD) mortality as new or reverted abnormalities, the results suggested that serial electrocardiograms (ECG) would contribute to proper risk assessment. Also, the inclusion of ischemic ECG findings significantly increased the predictive power of the Framingham score at age 70 for CVD.

While hypertension and dyslipidemia were consistent long-term risk factors for myocardial infarction at ages 50 and 70, the length of follow-up period and age at baseline affected the predictive power of ECG abnormalities, fasting insulin, BMI, and smoking.

For stroke, midlife values for blood pressure and ECG abnormalities retained prognostic value over long follow-up periods, even though they improved when re-measured in elderly participants. ApoB/apoA1 ratio, driven by apoA1, was associated with stroke in elderly but not middle-aged men. Hyperinsulinemia and diabetes mellitus were more specifically associated with ischemic stroke than with any-cause stroke.

In summary, the resting ECG carried prognostic information beyond conventional risk factors. Even though the low prevalence of ECG abnormalities at the age of 50 calls into question the role of the ECG as a screening tool, the additional risk information it carries with it justifies its regular and repeated registration above the age of 50.

Abstract:
First-line therapy for postmenopausal osteoporosis comprises antiresorptive medication such as bisphosphonates (BPs) and denosumab (Dmab; a human monoclonal antibody). Exercise is an effective non-pharmacological stimulus for bone, however, is traditionally dismissed as a singular therapy for osteoporosis. High-intensity resistance and impact training (HiRIT) applies the principles of osteogenic loading determined from animal trials. There is increasing evidence to support the feasibility and efficacy of HiRIT to safely improve bone health and indices of fall and fracture risk in postmenopausal women and middle-aged to older men. We hypothesised that the combination of exercise and bone medication may provide a more effective bone stimulus than either alone. To examine the influence of antiresorptive medication on the effects of bone-targeted exercise, we conducted a systematic review and meta-analysis of existing evidence, and a novel, randomised controlled exercise trial in postmenopausal women either on or off medication therapy. The thesis comprises five manuscripts, presented as four publications and one manuscript in preparation for submission. The first two manuscripts present a two-part review series on the effect of exercise intensity on bone in postmenopausal women. Part one is a systematic review (Chapter 3) and part two, a meta-analysis (Chapter 4). The systematic review included 100 trials, which examined the effect of 120 exercise interventions on bone mass, bone structure or bone turnover markers (BTMs) in healthy postmenopausal women on or off bone medication. Classification of each exercise intervention into low, moderate and high intensity, using predefined classification criteria, revealed the majority (95%) of trials have applied low to moderateintensity loading. Effects of exercise on bone structure and BTMs has only been evaluated in a small proportion of trials and heterogeneity of trial design and outcome measures made it difficult to draw conclusions. The meta-analysis included 53 RCTs (63 interventions) which reported BMD results derived from dual-energy X-ray absorptiometry (DXA). Results showed a positive relationship between exercise intensity and bone response for lumbar spine (LS) and total hip (TH) BMD, whereas femoral neck (FN) results were less conclusive, possibly due to the small number of studies in the high-intensity category. Resistance training was the most effective exercise type, potentially in combination with weight-bearing impact activities. Furthermore, preliminary evidence suggests that exercise (any type, any intensity) significantly reduces the risk of osteoporotic fracture. There was a small benefit of adding exercise to medication therapy at the FN but not at the LS or TH. Results are limited to a small number of studies to the extent that the influence of exercise intensity on medication therapy could not be examined. The three subsequent manuscripts comprise the study protocol (Chapter 5), and the main outcomes (Chapter 6) and secondary outcomes (Chapter 7) of the Medication and Exercise for Osteoporosis (MEDEX-OP) trial. The MEDEX-OP trial was an eight-month, randomised controlled exercise trial of postmenopausal women with low bone mass (T-score ≤ -1.0), on or off stable doses of antiresorptive bone medications (BPs or Dmab) for at least 12 months at entry. Eligible participants were randomly assigned, stratified by medication intake, to twice-weekly, 40-min, supervised HiRIT or a low-intensity control exercise intervention (Buff Bones®, BB) matched for training frequency and duration. Outcomes included spine, hip, forearm and whole body BMD, bone structure at the proximal femur, body composition, anthropometrics, indices of functional performance and posture, number of falls and fractures, quality of life related to mental and physical health and pelvic floor health, osteoarthritis symptoms, physical activity enjoyment, and willingness to pay for supervised bone-targeted exercise classes. Exercise and medication compliance and safety of the intervention (adverse events and injuries) were also monitored. A total of 115 participants were randomised at baseline; BB n = 44, HiRIT n = 42, BB-med n = 14, HiRIT-med n = 15. We found that HiRIT plus medications improved proximal femur BMD more than HiRIT-only or BB on medications. HiRIT was superior to BB for LS and trochanteric BMD, back and leg extensor strength, functional mobility and stature. We observed positive relationships between the maximum weight lifted in the deadlift exercise and changes in LS BMD and back muscles strength, as well as between maximum squat weight and changes in leg muscle strength. Compliance and retention rates were high for all groups. HiRIT increased willingness to pay for bone-targeted exercise and physical activity enjoyment, whereas BB only increased the latter. Neither of the programs led to changes in quality of life related to physical and mental health, pelvic floor dysfunction and osteoarthritis, nor resting blood pressure and heart rate. In summary, the current work confirms the benefits of HiRIT for musculoskeletal health and suggests that the combination of bone-targeted exercise with antiresorptive medication may be more beneficial for proximal femur BMD than either intervention alone. There is a positive relationship between exercise intensity and bone response at the spine and hip. The direct comparison of high to low-intensity exercise revealed superior effects of high-intensity exercise for spine, hip and forearm BMD, muscle strength and mobility and stature. We conclude that HiRIT is an efficacious, safe and appealing exercise program that is superior to other, bonetargeted exercise interventions applied at low to moderate intensity. The combination of HiRIT with first line antiresorptive medication therapy may be superior to HiRIT-alone for hip bone strength, however, a large-scale trial is needed to fully investigate this interaction.

Abstract:
The main focus of this thesis was to establish the effects of a novel method of undertaking isometric exercise training on resting arterial blood pressure in middle aged (45-60 years) males and to further determine whether isometric exercise training could generate concomitant adaptations in local or systemic vasculature function and structure. This novel method allowed exercise intensities to be set at a relative proportion of peak electromyographic activity (%EMGpeat). which provides a more accurate means of determining isometric exercise intensity than the traditional use of%MVC. Methods: Prior to the start of the experimental sIDdies preliminary tests were undertaken to determine the reliability of the equipment and measures used to determine the main dependant variables, including resting blood pressure using a non-invasive blood pressure monitor and vascular diameter, blood flow and velocity, using a Doppler ultrasound. During all three srudies participants completed either a unilateral or bilateral leg incremental isometric test during which heart rate, blood pressure and EMG were recorded. During the final study, resting heart rate, blood pressure and vascular measures were taken at pre, mid and post 8 weeks of isometric exercise training. Results: The linear relationship betvleen %EMG and heart rate reported in the initial study was not consistently evident in all subjects which further established the bilateral protocol as the preferred method for determining such relationships. The data from the second study involving bilateral leg isometric exercise indicated that these relationships in middle aged participants were linear in all cases, for both habitually active and sedentary individuals, showing that this method of prescribing isometric exercise intensity could be used in this age group. From the training data it is evident that following 8 weeks of bilateral isometric exercise training heart rate, SBP and mean arterial pressure (MAP) was significantly reduced in the higher (85%T) training group with concomitant local vascular adaptations. However, no significant change in resting blood press~e or vascular adaptations was evident in the lower (70%T) intensity group. These data has not been reported previously. Discussion: These results are in agreement with the majority of the previous research which have used isometric exercise training as an intervention for lowering arterial blood pressure. Furthermore, the findings lend support to the research evidence that" systeniic vascular adaptations are not responsible for the observed reductions in resting blood pressure foHowing isometric exercise training. Furthennore, the absence of changes in the 70%T group suggest the possibility of an exercise intensity threshold below which the exercise intensity is insufficient to stimulate cardiovascular adaptations.

Resumo: A disfunção do sistema nervoso autonômico e o aumento de doenças crônico- degenerativas se manifestam junto ao processo de envelhecimento, levando à alterações da modulação autonômica cardíaca, e consequentemente da variabilidade de freqüência cardíaca. Com relação à resposta dos sistemas nervoso autônomo e cardiorrespiratório as respostas adaptativas são ainda menos esclarecedoras evidenciando-se os questionamentos quanto à carga ideal de treinamento para a aquisição de adaptações proporcionais aos protocolos de treinamento isolados. Adaptações autonômicas decorrentes do treinamento físico aeróbio já são bem estabelecidas pela literatura, como a ocorrência da bradicardia de repouso e melhorias nos índices de variabilidade da frequência cardíaca. Contudo, outros tipos de treinamento, como o treinamento concorrente, que associa o treinamento com pesos junto ao treinamento aeróbio, são questionados sobre as adaptações obtidas. Este trabalho objetivou avaliar as adaptações autonômicas em resposta ao treinamento concorrente em homens e mulheres entre 40 e 60 anos, com hábitos de vida não ativos. Os voluntários foram subdivididos em 4 grupos, sendo um de treinamento concorrente para homens (TCH), um de treinamento concorrente para mulheres (TCM), grupo sedentário homens (SH) e grupo sendentário mulheres (SM). Antes e após 16 semanas do protocolo experimental, os voluntários foram submetidos à avaliação dos componentes autonômicos cardiovasculares expressos pela variabilidade da frequência cardíaca (no domínio do tempo e da freqüência), obtidos e analisados por meio dos registros dos intervalos RR do eletrocardiograma coletados em repouso supino e em respiração espontânea. Para avaliação da aptidão cardiorrespiratória (VO2pico) foi realizado um protocolo de rampa, em esteira rolante, com incrementos crescentes de velocidade até a exaustão. A força muscular foi avaliada por meio do teste de uma repetição máxima (1-RM). Dentre os resultados obtidos, foi possível verificar que o programa de treinamento concorrente proposto parece não alterar e não interferir negativamente nas variáveis cardiovasculares de repouso. Para nenhum dos grupos estudados foi verificada redução da frequência cardíaca de repouso, da pressão arterial, nem alterações nas variáveis autonômicas cardíacas. Além disso, na avaliação cardiorrespiratória, o TCH e o TCM apresentaram melhora significativa para o VO2pico (TCH = pré: 31,63±5,37 e pós: 35,78±5,23ml/kg/min; TCM = pré 26,18±3,00 e pós: 28,41±2,34). Para o grupo TCM ganhos semelhantes foram observados quando o percentual de modificação foi calculado. Já o componente da força muscular houve melhora significativa para o grupo TCH nos três exercícios testados (supino pré: 68,88±5,79 e pós: 86,13±9,78 kg; leg press pré: 190,63±28,02 e pós: 315,25±67,74 kg; rosca direta pré: 36,75±3,06 e pós: 46,50±4,69 kg) e para o TCM em apenas dois exercícios testados (supino pré: 39,87±4,58 e pós: 46,75±6,62 kg; rosca direta pré: 23,50±3,81 e pós: 26,00±2,13 kg). Desta forma, o treinamento concorrente parece ser uma boa alternativa como metodologia de treinamento e ganhos associados nas várias capacidades físicas estudadas, porém não causou alterações na função cardiovascular. Investigações adicionais são necessárias para estabelecer o efeito dos treinamentos com pesos e concorrente nas variáveis cardiovasculares de repouso
Abstract: The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing the questions regarding the optimal training load for the acquisition of proportional adjustments to the training protocols alone. Autonomic adjustments resulting from physical training are already well established in the literature, such as the occurrence of bradycardia at rest and improvement in indices of heart rate variability. However, other types of training, such as concurrent training, combining weight training with aerobic training, are asked about the changes obtained. This study aimed to evaluate the autonomic adaptations in response to concurrent training in men and women between 40 and 60 with non-active lifestyle. The volunteers were divided into four groups, one with concurrent training for men (TCH), one with concurrent training for women (TCM), group sedentary men (SH) and group sedentary women (SM). Before and after 16 weeks of the experimental protocol, subjects underwent evaluation of cardiovascular autonomic components expressed by heart rate variability (time domain and frequency), obtained and analyzed through the records of the electrocardiogram RR intervals collected at rest supine and breathing spontaneously. To evaluate the cardiorespiratory fitness (VO2peak) was performed a ramp protocol on a treadmill with increasing speed increments until exhaustion. Muscle strength was assessed by testing one repetition maximum (1-RM). Among the results, it was verified that the proposed concurrent training program do not seem to change and do not adversely affect the cardiovascular variables at rest. None of the groups was verified reduction in resting heart rate, blood pressure, or changes in autonomic variables. Moreover, in cardiorespiratory evaluation, TCH and TCM showed significant improvement for VO2peak (TCH = pre: 31,63 ± 5,37 and after: 35,78 ± 5,23ml/kg/min; TCM pré 26,18 = ± 3,00 and after: 28,41 ± 2,34ml/kg/min). For the group TCM similar gains were observed when the percentage change was calculated. Since the component of muscle strength significantly improved for the TCH arm in the three exercises tested (supine before: 68,88 ± 5,79 and after: 86,13 ± 9,78 kg, leg press before: 190,63 ± 2,28 and after: 315,25 ± 67,74kg; before arm curl : 36,75 ± 3,6 and after: 46,50 ± 4,69kg) and the TCM in just two exercise tested (supine before: 39,87 ± 4,58 and after: 46,75 ± 6,62 kg); before arm curl: 23,50 ±3,81 and after: 26,00 ± 2,13 kg .) Thus, concurrent training seems to be a good alternative training methodology and gains in the various physical capabilities assessed, but did not cause changes in cardiovascular function. Further investigations are needed to establish the effect of weight training and competing in cardiovascular variables at rest

Abstract:
This study sought to understand how middle-class, white, male baby boomers approach ageing in contemporary Western society. The thesis explored the relationship between bodily ageing and identity construction, and the influence of consumer culture in this process. Findings presented an agentic view of middle-aged men’s experiences of ageing that challenges traditional notions of ‘old men’. Specifically, these baby boomers did not identify as ‘old men’. Findings showed there is no ‘one-size-fits-all’ approach to ageing positively. Instead, myriad, complex, intersecting factors were involved in these men’s positive experiences of ageing. These differences resulted in multiple, nuanced pathways towards experiencing ageing positively.

Abstract:
In this thesis, Kochman examines the textual references to poetry in contemporary playwright Tracy Letts's "Man from Nebraska," "August: Osage County," and "Superior Donuts" and explores how specific references function as a "poetic exchange" between the protagonists and the respective agents of change or moral touchstones in each play and how these "poetic exchanges" suggest a diminishment or elevation of the intrinsic value of art -- specifically, poetry -- as a force for personal and cultural renewal. While Letts's writing is hardly "poetic" and his structure closer to "narrative," he focuses on "the repressed" - both emotionally and socially --and the redeeming qualities of poetry. Kochman argues that Letts's dramatic works do not merely challenge the gaps, ruptures, and contradictions in the "master narratives" of Western culture, but also suggest an alternative to the traditional American "narrative" focused on the individual by advocating a "poetic perspective" centered on the community. This perspective urges a shift from a rigid, linear, individual-goal oriented principle (as depicted in "August: Osage County" toward a principle of flexibility, unity, and synthesis (as advocated in "Man from Nebraska" and "Superior Donuts").
