Abstract:
SUMMARYDorper sheep are raised in extreme desert areas. Body mass loss and body fluid shifts were measured in Dorper rams denied water for 4 days and offered only wheat straw. The rams lost 16·3% body mass, 22·0% total body water volume, 35·1 % extracellular fluid volume and 41·7% plasma volume. On first drinking following dehydration, Dorpers were able to consume 19·7% of their dehydrated body mass and 100·3 % of their body mass loss. It was concluded that Dorpers can survive in harsh deserts through their ability to withstand dehydration and quickly replenish body mass losses when water becomes available.

Abstract:
With over two-thirds (71.6%) of the US adult population either overweight or obese, many strategies have been suggested for weight loss. While many are successful, the weight loss is often accompanied by a loss in lean body mass. This loss in lean body mass has multiple negative health implications. Therefore, weight loss strategies that protect lean body mass are of value. It is challenging to consume a significant caloric deficit while maintaining lean body mass regardless of macronutrient distribution. Therefore, the efficacy of various dietary supplements on body weight and body composition have been a topic of research interest. Chromium picolinate has been shown to improve body composition by maintaining lean body mass. In this paper we review some common weight loss strategies and dietary supplements with a focus on their impact on body composition and compare them to the effect of chromium picolinate.

Abstract:
With energy intake restriction and exercise remaining the key diet and lifestyle approaches to weight loss, this is not without potential negative implications for body composition, metabolic health, and quality and quantity of life. Ideally, weight loss should be derived almost exclusively from the fat mass compartment as this is the main driver of metabolic disease, however, several studies have shown that there is an accompanying loss of tissue from the fat-free compartment, especially skeletal muscle. Population groups including post-menopausal women, the elderly, those with metabolic disease and athletes may be particularly at risk of skeletal muscle loss when following a weight management programme. Research studies that have addressed this issue across a range of population groups are reviewed with a focus upon the contribution of resistance and endurance forms of exercise and a higher intake dietary protein above the current guideline of 0.8 g/kg body weight/day. While findings can be contradictory, overall, the consensus appears that fat-free and skeletal muscle masses can be preserved, albeit to varying degrees by including both forms of exercise (but especially resistance forms) in the weight management intervention. Equally, higher intakes of protein can protect loss of these body compartments, acting either separately or synergistically with exercise. Elderly individuals in particular may benefit most from this approach. Thus, the evidence supports the recommendations for intakes of protein above the current guidelines of 0.8 g/kg body weight/d for the healthy elderly population to also be incorporated into the dietary prescription for weight management in this age group.

Abstract:
SummaryStudy aim: The aim of this study was to evaluate the relationship between basic somatic features (body mass and height) and body mass loss in physically inactive young women and men exposed to thermal stress in a dry sauna.Materials and methods: The research was conducted in 2015 on 685 first-year full-time students (333 women, 352 men), aged 19–20 years old. Nude body mass was measured after the students dried off before and after using the sauna.Results: An analysis of regression equations indicated that an increase in the body mass of women and men leads to a significant increase in sauna-induced body mass loss. On the other hand, body mass loss decreased with an increase in height in women and men, but to a smaller extent. From among the tested somatic features, body height and body mass, body mass had a decisive influence on body mass loss. Body height had a minimal and statistically non-significant impact on body mass loss.Conclusions: The results of this study indicate that heavier individuals have an increased risk of dehydration and hyperthermia. Therefore, they should pay close attention to replenishing fluids lost in the sauna. The determination of body mass loss values after a visit to a dry sauna has practical significance because it supports the estimation of the fluid volume required for the maintenance of correct water balance.

Full text
Abstract:
Issues of body image and ability to achieve intimacy are connected to body weight, yet remain largely unexplored and have not been evaluated by gender. The underlying purpose of this research was to determine if avoidant attitudes and perceptions of one’s body may hold implications toward its use in intimate interactions, and if an above average body weight would tend to increase this avoidance. The National Health and Nutrition Examination Survey (NHANES, 1999-2002) finds that 64.5% of US adults are overweight, with 61.9% of women and 67.2% of men. The increasing prevalence of overweight and obesity in men and women shows no reverse trend, nor have prevention and treatment proven effective in the long term. The researcher gathered self-reported age, gender, height and weight data from 55 male and 58 female subjects (determined by a prospective power analysis with a desired medium effect size (r =.30) to determine body mass index (BMI), determining a mean age of 21.6 years and mean BMI of 25.6. Survey instruments consisted of two scales that are germane to the variables being examined. They were (1) Descutner and Thelen of the University of Missouri’s (1991) Fear-of-Intimacy scale and (2) Rosen, Srebnik, Saltzberg, and Wendt’s (1991) Body Image Avoidance Questionnaire. Results indicated that as body mass index increases, fear of intimacy increases (p<0.05) and that as body mass index increases, body image avoidance increases (p<0.05). The relationship that as body image avoidance increases, fear of intimacy increases was not supported, but approached significance at (p<0.07). No differences in these relationships were determined between gender groups. For age, the only observed relationship was that of a difference between scores for age groups [18 to 22 (group 1) and ages 23 to 34 (group 2)] for the relationship of body image avoidance and fear of intimacy (p<0.02). The results suggest that the relationship of body image avoidance and fear of intimacy, as well as age, bear consideration toward the escalating prevalence of overweight and obesity. An integrative approach to body weight that addresses issues of body image and intimacy may prove effective in prevention and treatment.

Abstract:
Youth obesity prevalence rates in the United States are trending down; however, for Hispanic youth, rates are increasing despite efforts toward a reduction. The purpose of this study was to evaluate the impact of a culturally focused intervention program on weight reduction of Hispanic youth age 2 to 19 through examination of body mass index (BMI) percentile outcomes comparing age, gender, distance to program, time in program, and season of enrollment. Review of literature supports ecological and cultural approaches requiring behavior modification tailored to family and community as successful in decreasing youth obesity. However, researchers have yet to establish how various variables impact intervention outcomes making it difficult to determine what aspects of the cultural approach is effective. The epidemiology triangle and the social cognitive theory approach were used to relate to findings. Use of retrospective clinical archival participant data dating from November 7, 2008 to February 23, 2015 was analyzed through the use of various statistical applications. The analyses of this study indicated that only one age variable had significant results. The category for age 8 to12 had a significantly higher change in BMI than the other groups (p <.05) . This research has the potential to contribute to social change since it reveals that interventions tailored for the 8-12 age group may significantly improve the effectiveness of the program in reducing BMI percentile, thus decreasing obesity rates and associated disease along with morbidity and mortality. This knowledge can benefit educators, community collaborative efforts, practitioners, and other researchers.

Full text
Abstract:
Sojourns at high altitude are often accompanied by weight loss and changes in body composition. The aim was to study body composition before and after 40 days high-altitude exposure. The subjects were four women and six men, non-smoking, healthy and active students and a scientist from Mid Sweden University in Östersund with a mean (SD) age of 26 (10) years. All subjects volunteered for a six-week trek to the Mount Everest Base Camp via Rolwaling in Nepal. Before the sojourn subject’s height was 177 (10) cm and weight was 71.9 (10) kg. Body composition was measured with Lunar iDXA at the Swedish Winter Sports Research Centre in Östersund before and after the trek. Total body mass (SD) decreased from 71.8 (10.0) kg before to 69.7 (9.4) kg after the trek (P=0.00). Total fat mass decreased from 14.7 (5.9) kg to 13.8 (4.6) kg (P=0.01). Fat percent decreased from 21.6 (7.9) % to 21.0 (7.2) % (P=0.03). Total lean mass decreased from 54.0 (10.0) kg to 52.9 (9.7) kg (P=0.01). Bone mineral content was unchanged, 3.04 (0.5) kg before and 3.03 (0.5) after (P=0.13). Thus both total body mass and total lean mass had decreased after a six week trekking in Nepal.

Psychology
Ph.D.
Currently, two-thirds of adults and one-half of children and adolescents in the United States meet criteria for overweight or obese weight status (Wang & Beydoun, 2007). While weight loss often is desired among these individuals, few achieve sustained weight loss maintenance. A model of motivation, affect, and long-term weight loss maintenance is proposed, based on Carver's model of behavior change (2004b) and related research. This investigation evaluated the model's proposed associations between approach and avoidance motivation, depressive and anxious affect, and caloric consumption within the context of a dietary lapse condition in the laboratory. Findings did not support the hypotheses that avoidance motivation would be negatively related to calorie consumption or that approach motivation would be positively associated with calorie consumption. Conversely, higher avoidance motivation was found to predict higher caloric consumption. Finally, this relationship was not mediated by depressive or anxious affect. Instead, consumption of high calorie foods alone was shown to fully mediate this relationship. Recommendations for future research are presented in the context of these findings.

Abstract:
This thesis explores various dilemmas in making theatre performances in the context of social disruption, trauma and death. Diverse discourses are drawn in to consider issues of body, subjectivity and spectatorship, refracted through the writer’s experiences of and discontent with making theatre. Written in a fractal-like structure, rather than a linear progression, this thesis unsettles discourses of truth, thus simultaneously intervening in debates about the epistemologies of the body and of theatre in context of the academy. Chapter 1: Methodological Anxieties Psychoanalytic theory provides a way in for investigating the dynamics of theatrical performance and its corporeal presence, by focusing on desire and its implication in the notions of loss and anxiety. The theories of the unconscious and the gaze have epistemological implications, shifting definitions of “presence” and “truth” in theatre performance and writing about theatre. This chapter tries to outline the rationale for, as well as to enact, an alternative methodology for writing, as an ethical response to loss that does not insist on consensus and truth. Chapter 2: (Refusing to) Look at Trauma This chapter examines the politics that strives to make suffering visible. Discursive binaries of public/private, dead/living, and invisible/visible underlie the politics of AIDS and sexuality. These discourses impact on the reception of Bill T. Jones's choreography, despite his use of modernist artistic processes in search of a bodily presence that aims to collapse the binary of representation (text) and its subject (being). The theory of the gaze shows this politics to be a phallocentric discourse; and narrative analysis traces the metanarrative that results in the commodification of oppositional identities, so that spectators participate in the politics as consumers. An ethical artistic response thus needs to shift its focus to the subjectivity of the spectator. Chapter 3: The Screen and the Viewer’s Blindness By appealing to a transcendent reality, and by constituting spectators as a participative community, ritual theatre claims to enact change. The “truth” of ritual rests not on rational knowledge, but on the performer’s competence to produce a shamanic presence, which director Brett Bailey embraces in his early work. Ritual presence operates by identification and belonging to a father/god as the source of meaning; but it represses the loss of this originary wholeness. Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

Full text
Abstract:
During recent decades, lumbar spinal stenosis (LSS) has become the most common indication for spine surgery, a change that coincides with a higher worldwide prevalence of overweight and obesity. Thus, surgical treatment of LSS in the overweight and obese population is common and increasing in scope. The overall aim of this thesis was to investigate whether body mass index (BMI) is related to the development of LSS, and whether BMI is linked to outcome after surgery for LSS. We further evaluated whether there are specific experiences of LSS from a patient perspective. Data were obtained for all patients registered in the Swedish Spine Register who had undergone surgery for LSS between January 1, 2006 and June 30, 2008. After adjusting for differences in baseline characteristics, patients with obesity showed both poorer results after surgery and a higher rate of dissatisfaction than patients with normal weight (odds ratio 1.73; 95% confidence interval, CI, 1.36-2.19). Furthermore, patients with obesity in the cohort reported modest weight loss at follow-up (2.0 kg; 95% CI, 1.5-2.4), and only 8% reported a clinical important weight loss 2 years after surgery. Our analysis of 389,132 construction workers, showed that overweight (incidence rate ratio, IRR 1.68; 95% CI, 1.54-1.83) and obesity (IRR 2.18; 95% CI, 1.87-2.53) were associated with an increased future risk in developing LSS when compared with patients with normal weight. To gain insight into the patients' perspective of LSS, we performed interviews with 18 patients who were on a waiting list for LSS surgery. The transcripts, analyzed with content analysis, revealed that living with LSS is a physical, mental and social challenge in which resources to cope with the condition are of major importance. In summary, obesity is associated with poorer results after surgery, and patients with obesity report modest weight loss during follow-up. In addition, obesity is associated with an increased risk to develop LSS. Our findings revealed that being a patient with LSS, naturally involves considerable suffering and pain, but it also implies being a person with his or her own resources who is able to cope with these adverse conditions.

Full text
Abstract:
Mixed Martial Arts (MMA) athletes are weighed 24 h prior to competition. In order to compete in a lower weight class MMA athletes will often rapidly lose weight via dehydration. Despite the prevalence, there is currently no known published data examining the effects of acute dehydration on physiology and performance in mixed martial arts athletes. The present study aimed to examine: i) the effects of 5% acute dehydration on performance (vertical jump, medicine ball throw, grip strength and repeated sled push) and physiology (body weight, haematocrit, urine specific gravity, serum osmolality and urine osmolality) of MMA athletes. A total of 14 MMA athletes between the ages of 18 and 40 y with at least 2 y of competitive experience were recruited. Participants performed a familiarisation session, followed by two experimental sessions including a control protocol (CONT) or a dehydration protocol (DHY) in a randomised order. During the DHY athletes cycled for 3 h in a heated chamber (40˚C and 30% relative humidity) wearing a sweat suit in order to lose 5% of their bodyweight (BW). Athletes then underwent a 3 h recovery period, during which they consumed fluids/food ad libitum. Athletes then performed a series of performance tests, including vertical jump, medicine ball throw, wrist grip and repeated sled push. A further 21 h recovery period was allowed before athletes performed the same tests. Prior to weight loss, immediately post weight loss, pre performance testing (3 h post weight loss) and 24 h post weight loss, urine and blood samples were collected and body weight was measured. A lower average speed during the repeat sled push (5.65 ± 1.3 km.h-1) was observed 3 h post DHY compared with 3 h post CONT (6.99 ± 0.85 km.h-1; P-1) when compared with 24 h post CONT (7.12 ± 0.95 km.h-1; P-1 and 9.14 ± 1.1 km.h-1 were observed 3 h post DHY/CONT and 8.82 ± 1.41 km.h-1 and 9.35 ± 1.06 km.h-1 24 h post DHY/CONT. A decreased time to fatigue and increased perceived exertion was also observed. The decrements in performance were observed at both 3 h and 24 h post DHY with the decrements still being present but not as large 24 h. When comparing measures of hydration in the DHY with CONT, significantly lower measures of hydration were observed 30 min post DHY and 3 h post DHY. None of the measured markers of hydration indicated athletes were dehydrated 24 h post DHY. The observations of this present study indicate that current weight loss practices in MMA and other combat sports may not be conducive to the best physical performance possible. Current practices should be reconsidered since performance was compromised even following 24 h of recovery. Future research should investigate possible physiological mechanisms behind the observed decrement in performance.

Abstract:
ABSTRACT Following a balanced diet is essential, not only for maintaining a good body shape, but it is also crucial for our health. By controlling our nutrition, we can reduce the symptoms and also the progression of many diseases such as diabetes, anemia, cardiovascular disease, movement disorders, and more. Of particular importance is the right proportion of the main energy sources - carbohydrates, proteins, and fats, which aim to reduce excess body fat and increase muscle mass. In search of an answer to whether a balanced diet is enough, we studied 20 volunteers to build a harmonious body. The present study focuses on the diagnosis and control of the main physical indicators of managed 20 to 30 years and how they are affected by 50 days balanced diet combined with and without strength training, divided into two groups - basic and experimental. Anthropometric parameters were measured using a body composition analyzer from the Japanese company TANITA. Based on the indicators of daily caloric intake and kilograms of muscle mass, the required daily intake of proteins, carbohydrates, and fats is calculated. In the main group, after 50 days, a decrease in body weight was reported on average by 5.87% (6.07 kg). What is concerning is the fact that body fat was reduced by only 1.8%, while muscle loss was 4.83% (3.73 kg). In the experimental group, which was on the same diet, but included strength training, the muscle mass was increased by 4.14% (3 kg) and a decrease in total fat by 3.05%. No significant differences are observed in total body weight - 0.89% (0.68 kg), due to the increase in muscle mass. After the research, we concluded that following a diet is not enough to build a harmonious body. This should be used in combination with a training process aimed at increasing muscle mass and lower in total body fat.

Abstract:
Most quadruped robots capable of running have employed bounding gaits at speeds far below those at which an animal of equal mass would gallop, which is a similar gait. This paper extends the spring-loaded inverted pendulum (SLIP) model to capture the key characteristics of trotting and galloping in biological systems. The objective is to establish a tool that will aid in determining the speed at which bounding or galloping is efficient for robotic systems. The SLIP model includes a linear damper in the legs to model all energy losses in a stride, and in the case of bounding, the body is taken to have an asymmetrical mass distribution. Results indicate that the model exhibits biological characteristics for both trotting and galloping, although duty factors are unrealistically low. Including leg mass in the models to account for additional energy loss does not offer improvement over the use of a linear damper alone.

Abstract:
Introduction: Obesity is a multifactorial chronic disease that can predispose to several comorbidities, including breast cancer. The Department of Health estimates the number of overweight people in Brazil is 65%. The relationship between weight and height (BMI, Body Mass Index) has been used by WHO to assess the degree of obesity in the population. Breast cancer is responsible for more than 8,000 deaths each year in Brazil. Despite advances in systemic treatment, surgery is one of the main treatments used, and obesity is a relevant factor that worsens the oncological prognosis and is predictive of perioperative complications. Objectives: The aim of this study is to assess the relationship between obesity and surgical complications in 5,657 breast cancer patients undergoing surgical treatment (conservative or radical) at Pérola Byington Hospital. Methods: A retrospective, cross-sectional study was carried out with 5,657 patients undergoing surgical treatment (conservative or radical) by the Braziliann Unified Health System (SUS) at the Women’s Health Reference Center at Hospital Pérola Byington from January 2011 to December 2019. Data were collected from the medical records of the institution. The patients were divided into six groups according to BMI=W/H2 (25), followed by hematoma, diagnosed in 72 patients, 59.7% overweight women. The third most common complication was infection of the surgical site in only 19 patients (0.3%), with 78.9% in overweight women. This fact can be explained by inadequate perfusion, deficiency of macro and micronutrients and hypoxia that impairs collagen synthesis, resulting in poor healing, causing dehiscence. From these data presented, it is possible to infer thatcomplications such as seroma, hematoma, infection of the surgical wound, dehiscence, and even loss of the surgical flap are strongly associated with increased body weight. Conclusions: We came to the conclusion that the increase in body weight, especially in patients with a BMI> 25, is an unfavorable factor for the occurrence of surgical complications in patients with breast cancer, and it is essential to provide guidance on the risks of complications in the preoperative evaluation for adjusting the best surgical procedure and mainly for considering late reconstruction.

Abstract:
Abstract Bed rest studies provide an opportunity to conduct ground-based studies of the physiological changes which occur on orbit. Astronauts are known to lose muscle and bone mass during space flights, and effective countermeasures are being sought. The muscle loss is extensive, even for short duration missions, but it is fairly easily regained upon return to the earth’s gravity. Bone loss, on the other hand, is a slower process. The effects are long lasting, and significant loss from a long duration mission may cause fracture when the body is subjected to the sometimes rigorous forces of gravitational environments. For this reason, studies are being done at NASA’s Johnson Space Center Bone and Mineral Physiology Laboratory on heavy resistive exercises that decrease or prevent loss of bone mineral density (BMD) in bed rest subjects.
