Music has been shown to reduce rating of perceived exertion, increase exercise enjoyment and enhance exercise performance, mainly in low-moderate intensity exercises. However, the effects of music are less conclusive with high-intensity activities. The purpose of this with-participant design study was to compare the effects of high tempo music (130 bpm) to a no-music condition during repeated high intensity cycling bouts (80% of peak power output (PPO)) on the following measures: time to exercise end-point, rating of perceived exertion (RPE), heart rate (HR), breathing frequency, ventilatory kinetics and blood lactate (BL). Under the music condition, participants exercised 10.7% longer (p = 0.035; Effect size (ES) = 0.28) (increase of 1 min) and had higher HR (4%; p = 0.043; ES = 0.25), breathing frequency (11.6%; p < 0.001; ES = 0.57), and RER (7% at TTF; p = 0.021; ES = 1.1) during exercise, as measured at the exercise end-point. Trivial differences were observed between conditions in RPE and other ventilatory kinetics during exercise. Interestingly, 5 min post-exercise termination, HR recovery was 13.0% faster following the music condition (p < 0.05) despite that music was not played during this period. These results strengthen the notion that music can alter the association between central motor drive, central cardiovascular command and perceived exertion, and contribute to prolonged exercise durations at higher intensities along with a quicken HR recovery.

Objectives: To clarify the interrelationship of high intensity exercise and durationof time on lipid profile, blood pressure and, body weight in young hyperlipidemic adults andto evaluate the beneficial effects on health in possible shorter duration of time. Study Design:Case control study. Setting: Department of Physiology, BMSI, JPMC, Karachi. Period: January2012 to April 2012. Methods: Total numbers of 60 volunteers moderately active, younghyperlipidemic adults, aged 30 to 50 years, thirty for each A (control), and B (high intensityexercise) group respectively were assigned to participate for 12 weeks exercise programwithout restricted caloric diet at pre–identified track of specific time. Lipids profile and age, sex,weight, BMI, blood pressure, and lab investigations like serum Total cholesterol, Triglycerides,LDL, and HDL, of each participant were recorded at baseline (0 day) and similarly on day30, 60 and 90 respectively. Results: At the end of the 12 weeks program in high intensityexercise group significant effects have been observed by lowering the level of total cholesterol,triglyceride (p <0.05) and lipoproteins variables, with increasing the level of HDL-c. While nosignificant change in blood pressure and weight reduction was observed between indicialand final measurement in control and high intensity exercise groups (p<o.o5). Conclusion:Finding of this study suggest that, high intensity exercise has positive effects on lipid profileby lowering the level of total cholesterol(TC), triglycerides(TGs) low density lipoprotein (LDL-c)and increasing the level of high density lipoprotein (HDL-c) in hyperlipidemic adults rapidlyin short duration of time, thus have beneficial effects by reducing the cardiac risk factors,chronic metabolic disorders and improving the cardio respiratory fitness but reduction in bloodpressure body weight can be achieved in short time by combination of high intensity exerciseand nutritional guidance of caloric restriction.

Abstract Objectives Increasing the reinforcing value of a stimulus occurs after repeated exposures to the reinforcer via neuroadaptations that increase the incentive salience of the stimulus. Exercise is a reinforcer and increasing exercise reinforcement (RRVex) may be dependent on simultaneously increasing tolerance for exercise intensity. Positive outcome expectancy (POE) of participating in an intervention can be an important determinant of treatment efficacy, such as when attempting to increase tolerance for exercise intensity or RRVex. We hypothesized that (1) high-intensity interval training (HIIT) that produces great discomfort would increase tolerance for exercise intensity, (2) adding a positive outcome expectancy (POE) component to HIIT would further increase tolerance for exercise intensity and, (3) increases in tolerance for exercise discomfort would mediate increases in RRVex. Methods A randomized controlled trial with a factorial design included HIIT + POE (n = 33 adults, n = 19 women) and HIIT-only (n = 33, n = 19 women) groups. Both groups participated in HIIT 3 d/wk for 6 wks. HIIT + POE received POE treatment each exercise session. Outcomes were measured at baseline, after 6 weeks of HIIT, and 4 weeks post-HIIT (10 wk). Changes in the RRVex were assessed by a progressive ratio schedule of reinforcement task. Other outcomes were outcome expectations, tolerance for exercise intensity, and behavior regulations of exercise. Results Outcome expectancy did not change in either group. Tolerance for exercise discomfort increased (P < .001) above baseline by 12% at 6 wk and 13% at 10 wk. Intrinsic, integrated, and identified behavior regulations of exercise were all increased (P < .01) at 6 wk and remained so at 10 wk. However, RRVex was not changed and change in RRVex was not correlated with change in tolerance for exercise intensity. Conclusions HIIT increases tolerance for exercise intensity and intrinsic, integrated, and identified behavior regulations of exercise. Funding Sources USDA-ARS.

Time constraints are cited as a barrier to regular exercise. If particular exercises can achieve multiple training functions, the number of exercises and the time needed to achieve a training goal may be decreased. It was the objective of this study to compare the extent of trunk muscle electromyographic (EMG) activity during running and callisthenic activities. EMG activity of the external obliques, lower abdominals (LA), upper lumbar erector spinae (ULES), and lumbosacral erector spinae (LSES) was monitored while triathletes and active nonrunners ran on a treadmill for 30 min at 60% and 80% of their maximum heart rate (HR) reserve, as well as during 30 repetitions of a partial curl-up and 3 min of a modified Biering-Sørensen back extension exercise. The mean root mean square (RMS) amplitude of the EMG signal was monitored over 10-s periods with measures normalized to a maximum voluntary contraction rotating curl-up (external obliques), hollowing exercise (LA), or back extension (ULES and LSES). A main effect for group was that triathletes had greater overall activation of the external obliques (p < 0.05), LA (p = 0.01), and LSES (p < 0.05) than did nonrunners. Main effects for exercise type showed that the external obliques had less EMG activity during 60% and 80% runs, respectively, than with the curl-ups (p = 0.001). The back extension exercise provided less ULES (p = 0.009) and LSES (p = 0.0001) EMG activity than the 60% and 80% runs, respectively. In conclusion, triathletes had greater trunk activation than nonrunners did while running, which could have contributed to their better performance. Back-stabilizing muscles can be activated more effectively with running than with a prolonged back extension activity. Running can be considered as an efficient, multifunctional exercise combining cardiovascular and trunk endurance benefits.

In recent years, several multi-user virtual environments (VEs) have been developed to promote motivation and exercise intensity in motor rehabilitation. While competitive VEs have been extensively evaluated, collaborative and competitive rehabilitation VEs have seen relatively little study. Therefore, this article presents an evaluation of a VE for post-stroke arm rehabilitation that mimics everyday kitchen tasks and can be used either solo or collaboratively. Twenty subacute stroke survivors exercised with the VE for four sessions, with the first and third sessions involving solo exercise and the other two involving collaborative exercise. Exercise intensity was measured using inertial sensors while motivation was measured with questionnaires. Results showed high motivation and exercise intensity over all four sessions, and 11 of 20 participants preferred collaborative over solo exercise while only 4 preferred solo exercise. However, there were no differences in motivation, exercise duration, or exercise intensity between solo and collaborative sessions. Thus, we cannot currently claim that collaborative exercises are beneficial for upper limb rehabilitation. Future studies should evaluate other collaborative VE designs in different settings (e.g., at home) and with different participant pairs (e.g., patient-unimpaired) to find effective ways to utilize collaborative exercises in motor rehabilitation.

Regelmessig fysisk aktivitet bedrer den fysiske formen, og er dokumentert å være en viktig bidragsyter med tanke på å redusere forekomsten av sykdom og dødelighet. Det maksimale oksygenopptaket, som er det beste målet på arbeidskapasitet, er vist å være en svært sterk indikator på dødelighet både hos friske og hos pasienter med hjerte-karsykdom. Regelmessig utholdenhetstrening for å øke maksimalt oksygenopptak er derfor anbefalt for bedret helse og økt livslengde. Selv om dette er etablert kunnskap, vet man lite om hvilken intensitet kondisjonstreningen bør gjennomføres med for å oppnå best mulig helsegevinst. Hensikten med denne doktorgradsavhandlingen var derfor å kartlegge hvilken intensitet i kondisjonstreningen som gir best effekt med tanke på å øke det maksimale oksygenopptaket blant pasienter med koronarsykdom. Vi ønsket også å studere hvorvidt intensiteten er viktig for å bedre fysisk form og redusere risikofaktorer for hjerte-karsykdom hos pasienter med metabolsk syndrom, som har en sterk opphopning av disse risikofaktorene. Derfor sammenliknet vi aerob intervalltrening med høy intensitet (80-90 % av maksimalt oksygenopptak) med kontinuerlig kondisjonstrening med moderat intensitet (50-60 % av maksimalt oksygenopptak) der total treningsmengde var lik. Videre ønsket vi å undersøke hvordan blodårenes funksjon og elastisitet ble påvirket av ulik type trening, både blant unge trente og utrente, og blant pasienter med metabolsk syndrom. Resultatene viste at trening med høy intensitet ga bedre effekter enn moderat intensitet for å bedre aerob kapasitet og redusere kjente risikofaktorer forbundet med hjerte-karsykdom, inkludert blodårefunksjonen. Avhandlingen kan derfor bidra med ny innsikt med tanke på bruk av aerob intervalltrening for mer effektivt å bedre kondisjonen og dermed helsen, både blant hjertesyke og hos individer med forhøyet risiko for fremtidig hjerte-karsykdom

The overall aim to this thesis was to identify if the use of self-regulated (SR) rest during high intensity training (HIT) can be used to increase endurance and power output measures between males and females. Study one aimed to determine if males and females can maintain mean power output (MPO) during repeated sprints when using self-regulated (SR) rest, and identify male and female response in MPO when SR rest is reduced. Participants completed four trials of 10 x 6 sec sprints separated by SR rest against 7.5% body mass (BM) as a resistance. If the mean power output (MPO) for all ten sprints in each trial had a coefficient of variation (CV) of ≤ 5.2%, then it was deemed that the participant was able to maintain their MPO. In trials 1-4 males significantly maintained their MPO greater than females in relation to their respected criterion sprint MPO data. In addition to this, only 85% of the participants could maintain their MPO when using SR rest (two males and one female failed). When SR rest was reduced by 10 and 15% there was no difference in CV between these two trials and the original 4 trials. However, MPO significantly dropped greater in females than in males SR rest was reduced by 15%. Therefore, this study indicates that males can use SR rest to maintain their MPO greater than females, and participants may be pacing their sprint efforts to maintain a sub-maximal MPO instead of their maximal MPO when SR rest is reduced by 15%. Study two aimed to compare endurance and Wingate power output adaptations to HIT with a fixed rest (30 sec) or self-regulated rest, and identify if reproducibility of MPO during HIT is correlated to endurance and Wingate power output adaptation. Male participants the same HIT protocol from Study 1 for six sessions over a two-week period. Participants completed the HIT with either SR rest or with a fixed rest (FR) of 30 sec between each sprint. Magnitude in change for time to exhaustion (TTE), time trial (TT) and Wingate power measures was greater in the SR group, whereas VO2 peak increased greater in the FR group. However, no strong correlation between maintaining power output and increasing endurance measures or power measures appeared. Whereas correlation data indicates that VO2 peak increased for the FR group due to a decrease in power output during the trials. Therefore, this study indicates that TTE, TT and Wingate power output experience a greater increase when rest is SR and with the aim of maintaining MPO during HIT. Study three aimed to compare the magnitude in change in VO2 peak, TTE, TT, and critical power (CP) when SR rest is reduced by 15 and 20% during HIT between males and females. Participants completed the same HIT protocol from the previous studies but completed eight HIT sessions over a four week period. Both training groups experienced a significant increase in endurance performance as measured via VO2 peak (males only), TTE, TT and critical power (20% group only). A larger aerobic response during the HIT was significantly correlated to an increase in VO2 peak in both males and females. Increases in critical power was significantly correlated to an improved TT time, which was also significantly correlated to increasing TTE. Indicating that TTE and TT improved due to an increase in greater power output. Reducing SR rest leads to a greater increase in endurance measures compared to non-reduced SR rest (Study 2), apart from females VO2 peak who saw no change. Conclusion: Overall this thesis can conclude that: 1) males appear to maintain their MPO greater than females when using SR rest and females experience a greater drop in trial MPO when SR rest is reduced. 2) Participants may be pacing in trials as CV remains unchanged but MPO decreases. 3) The CV method to identify successful SR rest to maintain MPO is unreliable and doesn’t take into account potential pacing tactics. 4). SR rest in HIT causes a greater increase in TTE, TT and Wingate power output measures, however, using a FR leads to greater increases in VO2 peak all in males. 5) Reduced SR rest causes a greater increase in TTE, TT and VO2 peak (males only) compared to SR rest, and also increases CP. 6) Maintaining MPO during HIT is not strongly correlated to increasing endurance or power output measures.

Resumo:

The Thoroughbred racehorse is capable of maintaining speeds of approximately 17 m/s for distances of over a mile. This represents an average speed and the Thoroughbred can reach speeds in excess of 20 m/s over short distances. The present series of studies was undertaken to investigate further the metabolic response to high-intensity exercise in the Thoroughbred racehorse. Unlike man, high-intensity exercise in the horse results in an increase in packed cell volume. This in turn causes acute changes in the colligative properties of blood and plasma. The changes in these properties were investigated and the effect on calculation and distribution of metabolites in blood and muscle was determined. The horse has a high capacity for lactate production compared to man and existing methodology for the assessment of muscle buffering capacity in biopsy samples was further developed and investigated. The horse was found to have a significantly higher muscle buffering capacity compared with man and it was calculated that this could be explained wholly on the basis of the higher muscle carnosine content in the horse. The metabolic response to high-intensity exercise was investigated using several exercise models, including single and multiple field gallops and treadmill exercise. A consistent finding was that high-intensity exercise in the Thoroughbred racehorse was nearly always accompanied by a reduction in muscle ATP content. The nature of the ATP decrease was further investigated using a treadmill exercise model. Muscle ATP decrease was found to occur at a particular exercise intensity rather than show a gradual decrease with increasing intensity. The intensity at which muscle ATP content began to decline significantly varied between individual horses, but in each case appeared to coincide with muscle lactate contents of approximately 70 mmol/kg dry muscle. The significance of the decline in ATP is discussed.

The aim of this series of studies was to investigate the effects of oral caffeine ingestion (5 mg . kg-1) on whole-body, short-term, high-intensity exercise (ST; representing an exercise intensity of between 100% -150% V02 max), an area that has received scant attention in the past. It was found that, in common with other 'open-ended' tests, one ST assessment, the maximal accumulated oxygen deficit (MAOD), appeared to lack both validity and reliability. Although traditional reliability markers of MAOD were favourable, the 95% limits of agreement were unacceptably large. In addition, the validity of MAOD was also found to be questionable because a study of elite runners revealed that a large proportion were unable to accomplish a plateau in the V02 -exercise intensity relationship. A follow-up study developed an original bespoke 'preloaded' ST cycling protocol that combined constant-rate exercise with an 'all-out' effort. This protocol appears to have several features that make it a more appropriate assessment to use in ergogenic studies than the MAOD. The work also considered the original, and as yet, undeveloped potential, for the assessment of rating of perceived exertion (RPE) during ST. It was shown for the first time that RPE (Borg scale; 6-20) could be used reliably during constant-rate ST. Three of the ten studies demonstrated that caffeine can be ergogenic during ST, with improvements averaging 11 % (95% GI, 7.4% -14.5%) above placebo treatment. In addition, the caffeine studies contributed to a meta-analysis of the effects of caffeine on test outcome that resulted in an effect size greater than zero, with 95% confidence intervals not crossing zero. The studies have examined potential physiological and metabolic mechanisms of action that may help explain caffeine's impact on ST. These suggest that there is some evidence that caffeine both stimulates anaerobic glycolysis and reduces electrolyte disturbance during ST. Finally this work has demonstrated for the first time that the perceptual response during constant-rate ST, as measured by RPE, is blunted following caffeine ingestion. It is concluded that caffeine is ergogenic during ST, and that while the exact mechanism(s) of action remains unknown, one consistent test outcome is a reduction in RPE during constant-rate ST.

Resumo:

Cortisol (C) and testosterone (T) are commonly suggested as markers of overreaching and the unexplained underperformance syndrome (UPS) as taken together they highlight the body s state of stress by indicating the body s catabolic/anabolic balance. Research in this area has focused on the resting concentrations of these hormones and provided inconsistent findings with increases, decreases and no changes reported when individuals are compared in an overreached state with a normally trained state. Little attention has been given to the exercise-induced responses of these hormones and whether this could be a reliable marker of overreaching/UPS. Overreaching will only occur with an intensification of training so the aims of the studies in this thesis were to determine the effects of intensified training on the exercise-induced responses of salivary and plasma C and T concentrations. Study 1 (Chapter 4) determined the salivary and plasma C, T and plasma adrenocorticotrophic hormone (ACTH) concentration responses in physically fit, healthy males to a double-bout cycle to fatigue protocol devised by Meeusen et al. (2004). They reported blunted exercise-induced hormonal responses to this protocol when well-trained cyclists were overreached compared with a normally trained state. Study 1 concluded that the exercise-induced responses of the salivary and plasma C and plasma ACTH concentrations were unaffected by a 4-day intensified training period. Blunted exercise-induced salivary and plasma T concentrations were found post-training but were due to blunted resting, basal T concentrations post-training compared with pre-training. The double-bout cycle to fatigue protocol did not elicit large C or T responses and so was not ideally suited to highlight alterations in the exercise-induced hormone responses. A high-intensity, short-duration exercise protocol (called the 55/80 bout) was established in Chapter 5 which induced robust elevations of salivary and plasma C and salivary T concentrations when in a normal trained state. Such a protocol could highlight any adaptations in the exercise-induced responses of C and T concentrations. It was also concluded that salivary and plasma C concentrations positively correlated if the peak post-exercise values were compared but not so with the salivary and plasma T concentrations. Chapter 6 and Chapter 7 concluded that blunted responses of the salivary C (Chapter 6) and T (Chapter 6 and Chapter 7) concentrations to a 55/80 bout occurred after an intensified endurance training period (~10 days). These results indicate that the 55/80 bout could be a useful detection tool of exercise-induced alterations in salivary C and T concentrations caused by an elevation of training loads in both recreationally active and elite athlete populations. The reproducibility of the salivary hormonal responses to the 55/80 bout needed to be established before it could be concluded that this was indeed a useful tool. Chapter 8 concluded that the responses of both salivary C and T concentrations to the 55/80 bout were reasonably reproducible with intra-individual variations of 12% (salivary C) and 7% (salivary T) reported. Chapter 8 also concluded that a familiarisation 55/80 bout was needed to reduce the variation in the responses of both salivary C and T concentrations. The final experimental chapter examined the response of salivary C and T over a competitive season in elite male triathletes and concluded that the 55/80 bout was unable to highlight any adaptations in the salivary C and T exercise-induced responses. This was suggested to be due to the low numbers of participants in this study and the ability of the triathletes to cope well with the elevations in training loads over the season. In conclusion, the studies in this thesis suggest that the exercise-induced responses of salivary C and T do alter due to an intensification of training loads. This alteration presents as a blunting of the exercise-induced responses of these salivary hormones. The 55/80 cycle bout can highlight this blunted response in both recreationally active and elite athlete male populations and therefore may be a useful tool to examine exercise-induced adaptations in salivary C and T concentrations caused by periods of intensified training.

This thesis investigated the effect of high intensity, intermittent exercise (HIIE) on fat loss in young, sedentary women. It attempted also to identify possible mechanisms underpinning exercise-induced changes in adiposity. Study 1 investigated some of the metabolic and hormonal responses to two variations of HIIE. Sixteen female subjects were tested. The first session involved a cycle ergometer VO2peak test. The next two sessions were completed in random order. After baseline measures the women did 20 min of HIIE. There was a short bout exercise of 8 s work, followed by 12 s relative rest and a long bout exercise of 24 s work followed by 36 s relative rest. Seven subjects had excess postexercise oxygen consumption (EPOC) and resting metabolic rate determined. Both exercise modalities made significant demands on the participants??? oxygen delivery systems. RER diminished over the 20 min of exercise and plasma glycerol concentrations increased. Lactate concentrations rose. Catecholamine concentrations were elevated postexercise. There was an elevated EPOC associated with above baseline fat utilisation. Study 2, a 15-week training study, was a randomised controlled trial comparing the effects of short bout HIIE and steady state (SS) exercise on fat loss. Forty-five women were randomly assigned to one of three groups: HIIE, SS, or control. Preliminary and posttraining testing included a DEXA scan and a VO2peak test including blood collection. All participants completed 3-d diet diaries and maintained their current diet for the course of the study. Participants exercised three times a week for the next 15 weeks under supervision. The HIIE group did 20 min of HIIE (8 s work:12 s rest) at a workload determined from the VO2peak test. The SS group cycled at 60%VO2peak , building to a maximum of 40 min exercise. Both exercise groups increased VO2peak . The HIIE group had a significant loss of total body mass (TBM) and fat mass (FM) when compared to the other groups. There was no change in dietary intake. There have been a number of studies examining the acute effects of HIIE but, to our knowledge, this is the first study examining the chronic effects of this particular exercise protocol.

Resumo:

Review question / Objective: The Effect of β-alanine Supplementation on Athletic Performance in Female Athletes: a Systematic Review of Randomized Control Trials. Condition being studied: β-alanine is an endogenously produced non-proteinogenic amino acid that can also be obtained through the consumption of foods such as meat. The ergogenic effect of β-alanine supplementation is linked to the levels of carnosine (a cytoplasmatic dipeptide to which β-alanine is a precursor). It has become one of the most common sports nutrition ergogenic aids, with typical doses at about 4 to 6 g per day that are ideal to elevate muscle carnosine concentrations by up 80%. This elevation happens regardless of high or low baseline levels (common in vegetarians, women and in older subjects) and chronic supplementation (and the associated increase of muscle carnosine levels) is known to be of particular interest in improving high-intensity exercise performance by enhancing intracellular H+ buffering, reducing muscle acidosis. It has been mostly proposed as beneficial in exercises between 60 seconds and 4 minutes, but some positive effects have been noted in other sport-related outcomes. The fact that women tend to have less muscle carnosine content then man, in addition to other characteristics of the female athlete, highlights the importance of understanding if the outcomes and magnitude of the effects already found and stablished in male athletes are, in fact, equivalent in the female athlete.

Resumo:

The article presents varieties and variants of relaxation techniques advisable to use after intense physical exertion. The concept of "relaxation" and understanding of its role in physical education to maintain health and harmonious development of youth are considered. Considering the fact that one of the main trends in sports remains the increase in the intensity of training and the need to improve the results of competitions, the problem of restoring the athlete's performance capacity after physical exertion is extremely relevant today. Understanding the causes of fatigue and the physiological mechanisms of recovery, control over the relevant processes, the rational use of modern methods of body relaxation and means of recovery are important for assessing the impact of physical stress on the body, the effectiveness of training programs, identifying overtraining, determining the optimal rest time after physical exercises, and therefore, are necessary to improve the athlete's training and achieving high results.
