Abstract:

The purpose of this thesis was to examine the influence of exercise motivation and body image on exercise behavior (using a multi-method approach), in order to better understand the phenomenon of unhealthy exercise. The first phase of this study was quantitative, and served to compare the exercise motivation (using Self-Determination Theory, Deci & Ryan, 1985) and perception of body image of "healthy" and "unhealthy" exercisers using a questionnaire. Specifically, 233 exercisers (102 males, 131 females) completed a questionnaire compiled of a self-reported exercise behavior scale (Salonen & Lakka, 1987), the Commitment to Exercise Scale (Davis et al., 1993), the Sport Motivation Scale (Pelletier et al., 1995), and the Body Cathexis Scale (Tucker, 1981). The self-reported exercise behavior scale and the Commitment to Exercise Scale were used to divide exercisers into "healthy" and "unhealthy" groups. In order to obtain a deeper, more complex, understanding of the phenomenon of unhealthy exercise specifically, a second qualitative phase (Phase 2) consisted of interviewing 4 exercisers (2 males, 2 females) identified in Phase 1 as having the most "unhealthy" exercise behaviors.

Abstract:

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter Balance 1 = 40% VO2R and 70% VO2R for session 1 and session 2, respectively; Counter Balance 2 = 70% VO2R and 40% VO2R for session 1 and session 2). The first session consisted of 3 sessions (morning, noon, evening) separated by an average of 3.5 hours at one of two intensities (40% VO2R or 70% VO2R). The second group of sessions were performed identical to the first, however, the intensity was altered depending upon counter balance. Baseline BP was measured prior to exercising. After each session, BP was measured at 2 intervals for the morning and noon sessions (immediately following and 20 minutes post-exercise); and at 3 intervals for the evening sessions (60 minutes post-exercise added) for both intensities. At 40% VO2R, BP decreased significantly at the morning (p = 0.007), noon (p = 0.018) and evening (p = 0.010) sessions at the 20 minute post-exercise interval. Although not significantly different, BP was observed to be lower at 60 minutes post-exercise interval. During the 70% VO2R session, BP was significantly lower at the morning 20 minute (p = .029) and evening 60 minute post-exercise measurements (p = .006) when compared to baseline. There was no significant difference noted between 40% and 70% VO2R intensities at eliciting a drop in BP at any interval at any time point. Although not statistically significant, 70% VO2R appeared to produce a further decrease at the 60 minute post-exercise measurement (102 mmHg) than did the 40% session (106 mmHg). The results of this study indicate that PEH may be elicited after a single 10 minute exercise session. Furthermore, multiple bouts of 10 minutes produce an accumulated decrease in BP that can be observed at the completion of the day.

Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2009.
ENGLISH ABSTRACT: It is well-known that acute and chronic aerobic and resistance exercise results in decreased blood pressure (BP) in hypertensive individuals. There is little evidence that water exercise has a similar effect on BP response. There is also no certainty regarding the magnitude and duration of post exercise hypotension (PEH) after either land or water-based exercise. Most studies were also performed under controlled laboratory conditions and very few characterised the PEH response under real life conditions. The current study endeavoured to examine the magnitude and duration of PEH after an acute session of water- and land-based exercise during free living conditions in persons with mild to moderate hypertension. Twenty-one men and women (aged 52 ± 10 years) volunteered for the study. All participants were pre-hypertensive or hypertensive. Participants completed a no exercise control session, a water exercise session and a combined aerobic and resistance land exercise session in random order. After all three sessions, participants underwent 24 hour monitoring using an Ergoscan ambulatory BP monitoring device. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) were monitored to determine changes from resting values after each session and to compare the PEH responses between land and water exercise. Overall, the land exercise treatment caused a 3.6 mmHg lower average SBP over 24 hours than the control treatment (P = 0.04). The average difference over 24 hours between the water and control treatments was 2.2 mmHg and between land and water exercise it was 1.5 mmHg (P > 0.05). During daytime, both land and water exercise resulted in significantly lower SBP (12.7 and 11.3 mmHg) compared to the control session (2.3 mmHg). The PEH response lasted for 24 hours after land exercise and nine hours after water exercise. There was no difference in the daytime DBP for the three treatments (P > 0.05). Although all three groups showed significant reductions during night time, both exercise treatments showed greater nocturnal falls in SBP, DBP and MAP than the control treatment.
AFRIKAANSE OPSOMMING: Dit is alombekend dat akute en chroniese aërobiese- en weerstandsoefening tot ‘n afname in bloeddruk (BD) lei in persone met hipertensie. Daar is egter min getuienis dat wateroefening dieselfde effek op die bloeddruk respons het. Daar is ook nie sekerheid oor die grootte en duur van post-oefening hipotensie na water- of landoefening nie. Die meeste studies is onder gekontrolleerde laboratorium omstandighede gedoen en min resultate is beskikbaar onder alledaagse lewensomstandighede. Die huidige studie het gepoog om die grootte en duur van die post-oefening hipotensie respons in persone met ligte tot matige hipertensie onder alledaagse omstandighede na ‘n akute sessie van water- en landgebaseerde oefening te ondersoek. Een-en-twintig mans en vrouens (ouderdom 52 ± 10 jaar) het ingewillig om aan die studie deel te neem. Alle deelnemers was hipertensief of pre-hipertensief. Alle deelnemers het ‘n kontrolesessie, ‘n wateroefeningsessie en ‘n gekombineerde aërobiese en weerstands landoefensessie, in lukrake volgorde, voltooi. Na elke sessie het die deelnemers 24 uur bloeddrukmonitering met ‘n Ergoscan wandelende bloeddruk monitor ondergaan. Sistoliese bloeddruk (SBD), diastoliese bloeddruk (DBD), gemiddelde arteriële bloeddruk en harttempo (HT) is gemonitor om die veranderinge vanaf rustende waardes na elke sessie te bepaal en om die hipotensiewe respons na land- en wateroefening te vergelyk. Landoefening het ‘n 3.6 mmHg laer gemiddelde SBD oor 24 uur tot gevolg gehad in vergelyking met die kontrolesessie (P = 0.04). Die gemiddelde verskil oor 24 uur tussen die water- en kontrolesessies was 2.2 mmHg en 1.5 mmHg tussen die land en water oefensessies (P > 0.05). Gedurende die dag het beide die land- and wateroefening gelei tot beduidende laer SBD (12.7 en 11.3 mmHg) in vergelyking met die kontrolesessie (2.3 mmHg). Die post-oefening hipotensie het 24 uur geduur na die landoefening en nege uur na die wateroefening. Daar was geen verskil in DBD gedurende die dag tussen die drie groepe nie (P > 0.05).

Abstract:

Cette thèse, intitulée « L’exploration fonctionnelle de repos et à l’exercice dans l'hypertension pulmonaire », est le résultat de différents travaux de physiologie clinique effectués dans le cadre des maladies vasculaires pulmonaires (MVP).La première partie de cette thèse est consacrée à l’étude de la diffusion des gaz dans l’hypertension artérielle pulmonaire (HTAP), l’hypertension pulmonaire thromboembolique chronique (HTP-TEC) et la maladie veino-occlusive pulmonaire (MVOP). Nous nous sommes particulièrement intéressé à l’étude de la double diffusion du monoxyde de carbone (DLCO) et d’azote (DLNO), permettant notamment la mesure du volume capillaire (Vc) et de la diffusion membranaire (Dm). Nous avons mis en évidence une diminution significative de ces paramètres dans les trois maladies et plus particulièrement dans la MVOP. Cette pathologie a la particularité de présenter un rapport DLNO/DLCO significativement plus élevé, évocateur de l’hémangiomatose capillaire associée à l’atteinte veinulaire. De plus, nous avons mis en évidence que le volume capillaire et la diffusion membranaire sont corrélés aux paramètres de capacités à l’exercice, dont la consommation en oxygène (VO2), dans un groupe de patients avec HTAP indemnes de toute comorbidité. Enfin, nous avons mis en évidence une corrélation significative entre la Dm et la survie dans l’HTAP.La deuxième partie de cette thèse fait référence a l’étude du cathétérisme cardiaque droit durant l’exercice. Dans un premier travail, nous avons collaboré à la proposition d’une nouvelle définition de l’hypertension pulmonaire à l’exercice (HTPe). Dans une cohorte rétrospective de patients investigués au Centre National de référence de l’Hypertension Pulmonaire, nous avons montré que l’association de résistances pulmonaires totales supérieures à 3 UW au pic de l’effort avec une pression artérielle pulmonaire moyenne (PAPm) supérieure à 30 mmHg présentent des valeurs de sensibilités et de spécificités élevées pour le diagnostic de patients avec MVP ou cardiopathie gauche sans hypertension pulmonaire de repos. Nous avons confronté ces résultats à une cohorte historique de sujets sains et trouvé des valeurs similaires. Dans un autre travail, nous avons analysé la concordance entre trois différentes définitions utilisées jusqu’à présent dans la littérature concernant l’HTPe, en montrant qu’elles ne sont pas équivalentes. Enfin, nous avons collaboré à une étude hémodynamique des sujets présentant une PAPm au repos comprise en 21 et 24 mmHg. Nous avons démontré que ces sujets présentent une hémodynamique d’effort anormale et qu’il existe une association entre la PAPm de repos et la fréquence de l’ HTPe.Dans la troisième partie de la thèse, nous avons contribué à l’étude de la distensibilité vasculaire dans les MVP. Dans une première étude rétrospective, nous avons collaboré à la validation du modèle alpha de distensibilité vasculaire. Nous avons démontré dans une cohorte de sujets avec maladies vasculaires pulmonaires que le coefficient alpha permet de détecter précocement des anomalies de la circulation pulmonaire chez des sujets présentant une PAPm de repos inférieure à 25 mmHg. De plus, dans une étude prospective, nous avons également étudié une nouvelle technique diagnostic : le signal Doppler pulmonaire, basé sur la pulsatilité de la paroi vasculaire, et donc reflétant la distensibilité des vaisseaux. Nous avons démontré que la performance diagnostique de cette technique était tout à fait acceptable en comparaison avec le cathétérisme cardiaque droit.Enfin, dans la dernière partie, nous avons exploré les différences de réponses à l’effort entre un groupe de patients avec HTAP et un groupe de patients avec une forme distale d’HTP-TEC. Nous avons observé une réponse ventilatoire différente, notamment avec une inefficience ventilatoire plus importante liée à un effet espace mort, expliquant une partie de la limitation fonctionnelle
This thesis, entitled « Rest and exercice functional investigation in pulmonary hypertension » is the sum of several physiological and clinical works in the field of pulmonary vascular diseases (PVD).The first part of this thesis is focused on the study of gas diffusion in pulmonary arterial hypertension (PAH), chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary veno-occlusive disease (PVOD). We have a special interest in the study of combined nitric oxide diffusion (DLNO) and carbon monoxide diffusion (DLCO) technic, which allows the measurement of capillary blood volume (Vc) and membrane diffusion (Dm). We have demonstrated a significant decrease of those parameters in the three forms of PH, specifically emphasized in PVOD. Furthermore, DLNO/DLCO ratio was remarkably increased in PVOD, suggesting a component of capillary hemangiomatosis associated to venular remodeling. Moreover, we have demonstrated that Vc and Dm were correlated to exercice capacity, such as peak VO2, in a group of PAH patients without confunding factors. Finally, we have found a significant correlation between Dm and survival in PAH.The second part of this thesis was about right heart catheterization during exercice. In this work, we have collaborated to the proposition of a new definition of exercice pulmonary hypertension (ePH). In a retrospective cohort of patients investigated in the French National Center for Pulmonary Hypertension, we have shown that total pulmonary resistance above 3 WU during exercise associated with a mean pulmonary arterial pressure (mPAP) above 30 mmHg displayed high sensitiviy and specificity for diagnosis of patients with PVD or left heart disease without resting pulmonary hypertension. We have compared these results with an historical cohort of healthy subjects and found similar results. In an other work, we have analyzed the concordance between three different definitions of ePH recently used in the litterature. We have demonstrated that they were not equivalent. Finally, we have collaborated to an haemodynamic study of subjects with resting mPAP between 21 and 24 mmHg. We have demonstrated that these subjects displayed abnormal haemodynamics during exercice. We have also demonstated that a progressive rise of resting mPAP was associated with an increase of the frequence of ePH.The third part of this manuscript is consacrated to the study of pulmonary vascular ditensibility in PVD. In a retrospective study, we have collaborated to the validation of the alpha model which allow the estimation of a distensibility coefficient. We have demonstrated in a cohort of patients with PVD that alpha allowed the early detection of abnormal pulmonary circulation in subjects with normal mPAP. In a prospective study, we have used a new technic called the lung Doppler signal (LDS) to diagnose PH, which investigates the pulsatile distensibility of pulmonary vascular walls. We have demonstated that LDS diagnostic performance was acceptable in comparison with the gold standard right heart catheterization.Finally, in the last part of the thesis, we have investigated differences of exercice profile between patients with PAH and distal CTEPH. We have demonstated an abnormal ventilatory pattern, with hyperventilation and marked ventilatory inefficiency in distal CTEPH. This is related to the increased physiological deadspace, which explained a part of fonctional limitation in distal CTEPH

Abstract:

The purpose of this study was to evaluate the intermodal reliability of perceptually-based exercise intensity among four machines: Treadmill (TM), Stationary cycle (CB), Body Trec elliptical arm/leg (BT), and AirDyne (AD). Nineteen subjects (8 male and 11 female; age 44 + 12 yrs) completed one GXT on each of the machines, following a mode-specific protocol. Subjects also completed two 15 minute production trials (PTs) on each machine at self-selected workrates corresponding to target RPEs of 11-12 (L) and 15-16 (H). In the PTs, workloads were self-adjusted through the first 5 minutes and then remained stable for the rest of the trial. Modes were randomly assigned, and subjects were blinded to the workload throughout each trial. Heart rate (HR) and oxygen uptake (V02) were obtained during the final 5 min. of each trial using a Polar HR monitor and Aerosport TEEM 100. Also, blood lactate (BLC) was sampled immediately following exercise at each intensity. Intermodal reliability was assessed using ANOVA, intraclass correlations (R), coefficients of variation (CV), and mean absolute differences for HR, V02, and BLC during the second PT. ANOVA revealed nointeraction for BLC at either the LOW or HIGH. Post -hoc analysis showed the TM and/or BT to produce significantly higher physiological responses at both intensity levels. At the L and H, intermodal Rs were: HR (.84/.88), VO2 (8/.77) and BLC (0.09/0.67). Significant intrasubject differences were observed at the L for HR (11-47bpm, VO2 (.04-1.46 L/min), and BLC (.29-12.94 mM/L). The H trials followed a very similar trend. Using a HR criteria of +2 beats/15 sec. to assess intrasubject reliability, 0% of the subjects were reliable at both the L and H. This data suggests that perceptually-based exercise across multiple modes is associated with significant intraindividual variability, and reliability is dependent upon the statistical design and physiological variable being used. In conclusion, it is recommended that extensive exercise testing be performed to ensure that individual participants can reliably use the RPE scale, prior to using an RPE value to prescribe the intensity of exercise.

Abstract:

Both positive and negative effects of exercise participation on health are shown in the literature. However, exercisers’ perceived health is still unexplored from this two-line influence perspective. The Perceived Health and Sport/Exercise Participation model (PHS/EP) served as theoretical framework for the study that aimed at testing the Perceived Health and Exercise Participation Profile (PHEPP) Questionnaire and examining factors involved in exercisers’ tendencies towards healthy versus unhealthy exercise participation and their association with perceived health, exercise satisfaction, goal orientation, self-esteem and physical self-perception. A package of four instruments was completed by 148 exercisers. The healthy tendency of exercise participation represented in the PHS/EP model was supported by the results obtained, whereas the unhealthy tendency needs further investigation and some related changes in the PHEPP questionnaire. Regression analyses confirmed some relationships between the PHS/EP model and established concepts such as goal orientation, self-esteem and physical self-perception dimensions. The results are discussed with reference to previous research and the PHS/EP model.

Abstract:

The purpose of this study was to compare the growth response elicited by an acute bout of resistance exercise (RE) conducted on a traditional weight stack device (WS) and a flywheel device (FW). Eight recreationally trained males (25 ± 9 y, 77 ± 27 kg) performed 4 sets of 7 repetitions of bilateral knee extension on each exercise device separated by 7 days. Muscle biopsies were obtained from the vastus lateralis at rest and 4 hrs post-exercise to examine the expression of selected myogenic and proteolytic genes. RE increased (P < 0.05) mRNA expression of Myogenin (3.6 vs. 3.6 fold), and MyoD (2.2 vs. 2.0 fold) and decreased (P < 0.05) expression of Myostatin (1.4 vs. 1.5 fold) to a similar degree on both exercise devices. There was no change in the expression of Atrogin-1, MuRF-1 or MRF4 following RE on either device. The only device mediated difference in the expression of the selected genes was observed in Atrogin-1 which was lower following RE on the FW versus the WS device. The current data shows that in the initial hrs following RE, use of the FW is as effective as the traditional resistance training devices (WS) in promoting the induction of genes involved with muscle remodeling and growth.

Abstract:

The study was designed to assess the effectiveness of the use of ownership of an exercise program to enhance exercise adherence. A design using the staggered introduction of the independent variable was used as a means of assessing the effectiveness of ownership on exercise adherence. Participants exercised in two separate exercise programs during the course of the study. Measures were taken on the: (a) number of fully completed workouts, (b) number of partially completed workouts, (c) number of missed workouts, (d) rating of perceived enjoyment, and (e) rating of perceived exertion. It was expected that each participant's attendance level would become more consistent and even be somewhat higher during the ownership phase. In addition, perceived exertion and enjoyment were also expected to be more consistent. Of the 6 participants, 4 showed the expected change in at least one measure.

Abstract:

The purpose of the study was two fold: a) to develop and to test the Perceived Health & Exercise Participation Profile (PH&EPP); b) to examine the relationship between exercisers’ perceived health, goal orientation, physical self perception and exercise satisfaction. The sample consists of 126 exercisers (43 Male, 83 Female with mean age 35.6 ± 9). The study included a new questionnaire - the Perceived Health & Exercise Participation Profile (PH&EPP) and three other instruments: 1) Physical Self-Perception Profile (PSPP); 2)Task & Ego orientation in Sport Questionnaire (TEOSQ); and 3) Rosenberg's Self-Esteem (RSE) Scale. The data were analyzed through SPSS 13.0 using Alpha coefficient, test-rest reliability, bivariate correlation and analysis of variance (ANOVA). Cronbach’s Alpha was satisfied

( .70) at 5 of 6 subscales. The test-retest reliability reached to significant level (ranging from .43 to .76) for all subscales. The majority of PH&EPP’s subscales reached to significant correlations except Health and Exercise as Life Values. The Satisfaction with Health and Exercise Participation reached to significant correlations with all PSPP’s subscales, Task goal orientation, and RSE except Ego goal orientation. The Perception of Exercisers obtained significant correlations at 3 of 5 PSPP’s subscales. Exercisers indicated more task goal orientation than ego goal orientation. The results are discussed from the point of view of the Perceived Health and Sport/Exercise Participation model.

Abstract:

In order to examine the effects of exercise intensity on the post exercise elevation in esophageal temperature (DeltaTes), 8 male subjects performed 15 minutes of treadmill running exercise at 3 different exercise intensities, subthreshold (70% VO2max), threshold (84% VO 2max, and suprathreshold (93% VO2max), followed by an upright 45 minute recovery period. In addition, the effects of exercise intensity on the internal temperature threshold for cutaneous vasodilation (Tdil ), as well as post exercise blood pressure, cutaneous blood flow (SkBF) and cardiovascular conductance (DeltaCVC), were examined. Significant differences (p < 0.05) in DeltaTes were found between the 3 exercise intensities during exercise, as well as between suprathreshold (0.91°C), and threshold (0.56°C)/subthreshold (0.44°C) intensities during the recovery period. The elevated DeltaTes remained significantly above pre-exercise values for the entire recovery period for all 3 exercise intensities. Exercise intensity also demonstrated an effect on Tdil during exercise where significant differences were found between the 3 exercise intensities (0.26°C, 0.47°C, 0.84°C for subthreshold, threshold, and suprathreshold intensities respectively). However, no significant correlation was found between Tdil, and post exercise DeltaTes. Finally, a state of hypotension with respect to pre-exercise was observed during recovery from suprathreshold exercise. This could explain the significantly higher post exercise elevation in DeltaTes from subthreshold and threshold exercise.

Abstract:

The current study is exploratory in nature and is the first to consider Sport, Exercise, and Performance Psychologists (SEPP) as proxy-agents for exercise. The primary focus is on three questions: Who would be interested in using a SEPP as a proxy-agent for exercise, do certain factors influence interest, and what specific self-regulatory mental skills are certain people interested in learning from a SEPP?

Two hundred and twenty-eight participants anonymously completed a survey online through Qualtrics. To answer the first question, participants in the age ranges of 18–22 and 23–49 were most interested and participants in the age range of 50 and higher were least interested. Participants who reported making less than $20,000 a year were the most interested, and participants who reported making more than $150,000 were the least interested. Participants who identified as being in the contemplation and action stages of change showed the most interest, whereas participants in the maintenance stage of change showed the least. To answer the second question, self-regulatory efficacy negatively influenced interest, whereas proxy-efficacy positively influenced interest. For the final question, participants were most interested in learning skills to manage their energy, and least interested in help reducing anxiety towards exercise from a SEPP. This study’s findings are important to the growing body of research regarding the best practices to embed long-term commitment to exercise behavior in individuals.

Abstract:

Exercise-induced hypoxemia [EIAH, arterial PO2 < 90 mmHg and/or alveolar-arterial oxygen partial pressure gradient (A-a DO2) ≥ 25 mmHg] occurs during strenuous exercise in some healthy women. There is conflicting opinion if performing successive bouts of strenuous exercise reduces the severity of EIAH. The aim was to (a) test the hypothesis that the severity of EIAH would be reduced with three successive bouts of strenuous exercise, (b) to determine if repeated bouts of exercise increases hyperventilation thus improving arterial PO2. Seven fit female subjects with EIAH [arterial PO2 or PaO2= 88 +/- 2 mmHg, A-a DO 2 = 25 +/- 3 mmHg and 7 fit female control subjects (PaO2 = 100 +/- 5 mmHg, A-a DO2 = 16 +/- 5 mmHg) performed three bouts of intense exercise on a cycle ergometer at 236 +/- 27 watts [oxygen consumption at end of each set = 48 +/- 6 mL/kg/min, or 96 +/- 5% of maximum] for 5 min each with 10 min of rest between sets. Arterial PO 2 increased [EIAH Delta = +4 +/- 5 mmHg. 95% CI = 0.6 to 7.8; Control Delta = +2 +/- 2 mmHg. 95% CI = 0.4 to 3.6] and arterial PCO 2 or PaCO2 decreased [EIAH Delta = -5 +/- 4 mm Hg, 95% CI = -7.4 to -2.2; Control Delta = -4 +/- 2 mmHg, 95% CI = -5.8 to -2.4] between set 1 and set 3 (P< 0.05). Also, 34% of the variance in the change in PaO2, was explained by the variance in the change of PaCO2 (P < 0.05). In conclusion, repeat exercise improves PaO2, which is related to improved hyperventilation.

Abstract:

The purpose of this study was to investigate whether there is a greater reduction in appetite following a high intensity interval training (HIIT) exercise session compared to a steady-state exercise (SSE) exercise session. Six subjects completed all three trials in a random, counterbalanced order, measuring subjects? perceived appetites throughout the trial. HIIT was 10 two-minute bouts of high-intensity exercise separated by one minute rest, SSE was 30 minutes moderate intensity exercise, and control was 40 minutes rest. Eleven visual analog scale (VAS) surveys were completed to measure perceived appetite and taste preferences. HIIT significantly lowered appetite scores compared to the control trial immediately after exercise: ?how hungry do you feel? (p = 0.0476); ?how satisfied do you feel?? (p = 0.0116); ?how full do you feel?? (p = 0.0225). No other significance was found. These results strengthen previous research that HIIT may lead to greater suppression of appetite immediately following exercise.

Abstract:

Twenty subjects were audio and video taped during their exercise leadership examination. The tapes were used to code the interactions that occurred between the exercise leaders and the participants in the simulated cardiac rehabilitation exercise session using an interaction analysis system developed specifically for this physical activity setting group. The system identified interactions that could occur during the warm-up, stimulus, and cool-down phases of the session. The tapes were coded using the Datamyte 801 Observational Recorder. The phases of the sessions were coded individually. A frequency count was made as the interaction categories occurred. The frequencies were converted into rates of interaction (f•min⁻¹) for comparison. The mean rates of interaction were low for the phases and overall (warm-up= .38/min; stimulus= .59/min; cool-down= .29/min; total= .46/min). The individual subject's rates of interaction were all less than 1 interaction per minute (minimum= .28/min; maximum= .72/min). Related t-tests across category facets between phases showed the instruction and explanation facets in the warm-up phase differed significantly from the same facets in the stimulus phase. The compliance facet differed significantly in the stimulus phase from the compliance facet in the other two phases. The monitor facet in the stimulus phase differed significantly from the monitor facet in the cool-down phase. There was no significant differences across facets between the warm-up and cool-down phases. Higher rates of interaction occurred more frequently in the stimulus phase. The coding showed the differences in the interactions of the exercise leaders in the different phases in the simulated exercise session. The low rates of interaction suggest that the exercise leaders may have been reactive to the specific examination situation in which these data were collected.

Abstract:

Friske gravide anbefales å trene regelmessig under svangerskapet for å fortsette å oppnå de samme helsegevinstene som ved trening i ikke-gravid tilstand. Når det gjelder forebygging og behandling av svangerskapsrelaterte plager, har det ikke tidligere vært gjennomført store randomiserte kontrollerte studier for å studere mulig effekt av trening i svangerskapet. Dagens kunnskap er hovedsakelig basert på observasjonsstudier. TRIP-studien er en to-armet, to-senter, randomisert kontrollert studie og ble gjennomført i perioden 2007-2010. Studien inkluderte 855 friske, gravide kvinner fra Trondheim og Stavanger. Kvinnene ble tilfeldig fordelt i en treningsgruppe og i en kontrollgruppe. Kvinnene i treningsgruppen ble tilbudt et 12-ukers standardisert treningsprogram med ukentlig gruppetrening, ledet av fysioterapeut, og to dager egentrening. Kvinnene i kontrollgruppen fulgte vanlig svangerskapsomsorg. Kvinnene ble testet i svangerskapsuke 18-22 og retestet i svangerskapsuke 32-36. Målet med denne studien var: I) å undersøke om deltagelse i treningsprogrammet kunne redusere forekomsten av svangerskapsdiabetes og gi bedre insulinresistens, II) å undersøke om kvinner i treningsgruppen rapporterte mer rygg- og bekkensmerter enn kvinner i kontrollgruppen, III) å undersøke om kvinner i treningsgruppen som ble tilbudt et generelt treningsprogram inkludert bekkenbunnstrening, rapporterte mindre inkontinens enn kontrollgruppen og IV) å undersøke om energiforbruket, målt med en fysisk aktivitetsmonitor, SenseWearTM Pro2 Armband, er forskjellig fra energiforbruket målt med indirekte kalorimetri. Totalt 55 % av kvinnene i treningsgruppen trente tre ganger per uke eller mer på moderat til høy intensitet på slutten av svangerskapet. Til sammenligning trente 10 % i kontrollgruppen tilsvarende (p<0.001). I) Det var ingen forskjell på gruppene i forekomst av svangerskapsdiabetes eller insulinresistens. II) Andelen kvinner med rygg- og bekkensmerter var lik i begge gruppene, men færre kvinner i treningsgruppen var sykmeldt på grunn av ryggog bekkensmerter. III) Forekomsten av urininkontinens var mindre i treningsgruppen, og treningsprogrammet viste seg å ha både forebyggende og behandlende effekt. Det var ingen forskjell på gruppene i andel kvinner som rapporterte analinkontinens. IV) SenseWearTM Pro2 Armband viste seg å være en god fysisk aktivitetsmonitor for å registrere totalt energiforbruk hos gravide. Resultater fra TRIP-studien understøtter de generelle anbefalingene om at gravide kvinner bør trene i svangerskapet. En grundig instruksjon i korrekt bekkenbunnstrening og et bekkenbunnstreningsprogram bør inngå i treningsgrupper for gravide kvinner

Abstract:

Background. Regularly exercising is diﬃcult, some people stop exercising either due to it not being fun or they might not see any results of the eﬀort they put in. Exercise and gaming or also know as exergaming, is a way to combine the fun entertainment of games with the health beneﬁts of exercise. Objectives. The objective of this study is to conduct an experiment to ﬁnd out if people are more interested in an exercising app which has been gamiﬁed compared to a normal exercising app. Gamifyingsomethingsuggeststhatsomethingwhichisnotconsideredagamemedium is taken, and then inﬂuence with game related aspects. Methods. A prototype was created to show the participants both sides of the exercise apps, one normal app which resembles an everyday exercising app, and one gamiﬁed app which shows the user their progress in a fashion similar to role-playing games with levels and quests. The participants of the test will try both apps and later vote in a survey whichever they liked the most. Results. While only about 60% of the participants had prior experience with exercise apps, 90% would rather choose the gamiﬁed app over the normal app. 95% of the participants were regular gamers. Conclusions. The vast majority of the participants preferred the gamiﬁed version of the app over the normal one. Speciﬁcally mentioning that they ﬁnd it more interesting and that they enjoy the upfront progression system a lot more since they are used to it from the games they play on their free time

Abstract:

OBJECTIVE:The aim of the study was to evaluate whether a repeated exercise challenge test requires reconsideration of the final exercise-induced bronchoconstriction diagnosis due to a difference in test results, and if so, whether the difference is associated with exercise intensity. METHOD: A total of 20 referred subjects with symptoms strongly suggesting exerciseinduced bronchoconstriction performed two exercise challenge tests on a treadmill. The exercise protocol of the repeated test was adjusted. Forced expiratory volume in 1 second was measured before and at 1, 3, 6, 10, and 15 minutes after exercise. Ventilation and heart rate were measured during exercise. RESULTS: The exercise intensity was not significantly different between the two tests, yet five subjects tested positive in both tests. Ten subjects tested negative in both tests. Three subjects tested positive in the first test only, while two subjects tested positive in the second test only. CONCLUSION: Our study showed a 25% divergence in the diagnostic results of two consecutive exercise challenge tests on subjects with symptoms strongly suggesting exerciseinduced bronchoconstriction. The difference in the test results was not explained by a difference in the exercise intensity. Keywords: exercise challenge test, exercise-induced bronchoconstriction, forced expiratory volume in one second

Abstract:

Exercise participation is linked to mental health and wellbeing. However, we need to identify optimal settings for promoting exercise-associated wellbeing outcomes, and for promoting exercise adherence. The literature suggests environmental settings may be important. The aim of this thesis was to rigorously test influences of environmental settings on exercise-related wellbeing outcomes. These over-arching research questions guided the experimental chapters: (i) is there an optimal green exercise environment for promoting wellbeing? (ii) When exercise is controlled, are findings consistent with previously reported psychological outcomes? (iii) Do environmental settings influence social outcomes of exercise or intentions to repeat exercise behaviours? Via field-based sampling, Chapter 3 found large proportions of affective benefits were universally obtainable across four typical green exercise environments, and suggested that the processes component of green exercise warranted further investigation; however, this method lacked control. Chapter 4 used laboratory-based methodology to control exercise and isolate the visual environment; consistent with both theory and previous research, nature environments facilitated wellbeing-related attention restoration. However, this method did not provide an accurate multisensory experience, therefore lacking ecological validity. Chapter 5 investigated methodologies for controlling the exercise component, comparing wellbeing-related outcomes of indoor versus outdoor exercise. This was important because previous research had not rigorously controlled exercise, therefore potentially confounding its findings. Results for environment-related exercise differences and affective outcomes were inconclusive. Chapter 6 merged laboratory-based methods with the indoor versus outdoor exercise paradigm, ensuring control and ecological validity. Environmental setting did not influence perceived exertion or mood; green settings promoted attention restoration and social interaction; for green exercise, social interaction predicted exercise intentions. Green exercise promotes wellbeing improvements; environmental influences on affective outcomes may be contributed to by differences in exercise performed. Independent of exercise differences, green environments promote attention restoration and social interaction during exercise, which may in turn influence exercise intentions.

Abstract:

It has been well-documented in the literature that there are many physical and psychological benefits to be derived from regular aerobic exercise. It has also been noted that adherence/compliance to aerobic exercise regimens tends to be quite low. Investigators have found that a number of factors tend to correlate with adherence, but it has been difficult thus far to determine a mechanism which underlies a tendency to adhere versus a tendency to drop-out. This study examined the problem of non-adherence from the perspective of Self-Efficacy Theory (Bandura, 1977). Subjects for this investigation included all patients seen during a four week period in the Cooper Clinic at the Aerobics Center in Dallas, Texas. Patients at the clinic receive a complete physical examination and health prescriptions based upon the results of their examination. During this four week period, half were administered a Self-Efficacy Questionnaire. Approximately three months later all patients seen during this four week period received a followup (adherence questionnaire in the mail). It was hypothesized that there would be a positive relationship between responses on the Self-Efficacy Questionnaire and responses on the Adherence Questionnaire. A second hypothesis stated that there would be a positive relationship between items which specifically pertained to exercise on each of the questionnaires. In addition, it was expected that there would be no difference in adherence rates between those who made self-efficacy judgments and those who did not. Results of a t-test conducted between the group which made self-efficacy judgments and the group that was not asked to make such an evaluation demonstrated no significant difference in adherence rates. A correlational analysis revealed that there was not a statistically significant relationship between total self-efficacy scores and total adherence scores. There was, however, a statistically significant relationship between levels of exercise self-efficacy and levels of exercise adherence. In addition to these main variables of interest, correlations between other variables (sex, age, percent bodyfat, etc.) were examined and discussed.

Abstract:

Despite pharmacological advances, exercise remains a cost effective preventative for cardiovascular disease (CVD) by acutely and chronically lowering systolic blood pressure (SBP). Although numerous studies have investigated aerobic and resistance training’s role in eliciting an acute SBP response termed post-exercise hypotension (PEH), few researchers have investigated how performing both cardiovascular and weight training in a single session (concurrent training) or how different prescriptions for order of exercise modality will elicit this PEH response; no known studies have attempted altering the order of exercise types within each session. This study seeks to determine if the order of exercise type will affect a PEH response following concurrent exercise. Participants (n=13), considered low risk for cardiovascular disease participated in a control session, graded exercise test (GXT) and two concurrent sessions, with concurrent sessions counterbalanced for order of exercise mode. Recovery SBP was analyzed in the laboratory for sixty minutes and for twenty-four hours thereafter using an ambulatory blood pressure monitor. All exercise conditions elicited a depression in SBP; however, only the cardiovascular-weight training (CVWT) concurrent session elicited PEH (p = 0.05). However, there were no differences in SBP attenuation between conditions. There was no main effect for PEH between conditions during twenty-four hour assessment. With no statistically significant differences in the magnitude of PEH twenty-four hours after exercise, it may be determined that the order of exercise does not vi affect the preventative attributes of aerobic and resistance exercise in regards to acute SBP response. Furthermore, only exercise involving resistance training (CVWT) provoked PEH during the first 60 minutes; therefore it may be argued that individuals should pair cardiovascular exercise with weight training in order to elicit the greatest cardiovascular benefits. Future studies should consider evaluating the effect of time of day and PEH following concurrent exercise to determine if pairing exercise modalities will at different times will affect the blood pressure response.

Abstract:

Exercise induces a residual post-exercise increase in the core temperature threshold at which cutaneous vasodilation and sweating begins. The hypothesis that exercise intensity causes a parallel increase in the post-exercise onset threshold for cutaneous vasodilation mediated by an attenuation of active vasodilator activity, was tested in nine subjects. The effect of exercise intensity on the esophageal temperature threshold for the onset of sweating was also evaluated. Esophageal temperature was monitored as an index of core temperature while sweat rate was measured using a ventilated capsule placed on the upper back. Increases in forearm skin blood flow and mean arterial blood pressure were measured and used to calculate cutaneous vascular conductance at two superficial sites, one with intact alpha-adrenergic vasoconstrictor activity and one infused with bretylium tosylate. On four separate days, subjects either remained seated for 35 min or performed 15 min treadmill running at 55, 70 or 85% VO2max followed by 20 min seated recovery. A liquid conditioned suit was used to increase mean skin temperature until cutaneous vasodilation and sweating occurred. It is concluded that intensity of exercise has a prolonged residual effect on the post-exercise vasomotor and sudomotor response by increasing the esophageal temperature at which onset of vasodilation and sweating occurs. Furthermore, the post-exercise increase in onset threshold for vasodilation is likely caused by an attenuation of active vasodilator activity modulated by baroreceptor reflexes in response to post-exercise hypotension.

Abstract:

Purpose: To determine the effect of four postexercise beverages, differing in macronutrient content, on metabolic response to an acute resistance exercise bout.

Methods: Forty male subjects performed five sets of eight repetitions at 80% 1RM for leg press and leg extension, and then consumed one of four postexercise beverages (Placebo, PL: a carbohydrate-electrolyte beverage, CE; or one of two milk-based beverages, MILK 1: 1% chocolate milk; MILK 2: a high protein milk beverage). Indicators of muscle protein synthesis (MPS) were assessed before and 1-hr after consuming a postexercise beverage. Muscle protein degradation (MPD) was examined the day before and the day of exercise.

Results: No significant differences were found among groups in MPS. The resistance exercise bout increased the amount of eIF4E-eIF4G by 4.5% 1-hr postexercise (p<0.05) without affecting the amount of eIF4E-4E-BP1. One hour after beverage consumption, serum total amino acid concentration increased for MILK 1 (p=0.003) and MILK 2 (p<0.001) but decreased for CE (p=0.028) and PL (p=0.276). Consumption of MILK 1, MILK 2, and CE significantly increased circulating levels of serum insulin (p<0.001). Serum growth hormone increased 3-fold as a result of the exercise bout but fell to baseline for all groups by 60 min (p<0.001).

Conclusion: The resistance exercise bout was anabolic as shown by the increase in the active eIF4E-eIF4G complex and serum growth hormone. Consumption of MILK 2 led to the most optimal environment for muscle anabolism; however, none of the experimental beverages influenced the measured indicators of muscle protein translation 1-hr after ingestion.
