Book excerpt: There is no doubt that if the field of exercise physiology is to make further advancements, the various specialized areas must work together in solving the unique and difficult problems of understanding how exercise is initiated, maintained and regulated at many functional levels, and what causes us to quit. Exercise is perhaps the most complex of physiological functions, requiring the coordinated, integrated activation of essentially every cell, tissue and organ in the body. Such activation is known to take place at all levels - from molecular to systemic. Focusing on important issues addressed at cellular and systemic levels, this handbook presents state-of-the-art research in the field of exercise physiology. Each chapter serves as a comprehensive resource that will stimulate and challenge discussion in advanced students, researchers, physiologists, medical doctors and practitioners. Authored by respected exercise physiologists from nineteen countries, each chapter has been significantly updated to provide up-to-date coverage of the topics and to offer complete descriptions of the many facets of the most physiological responses from a cellular to an integrative approach within individual body systems in normal and disease states and includes some chapters that are rarely addressed in exercise physiology books, such as the influence of exercise on endothelium, vasomomotor control mechanisms, coagulation, immune function and rheological properties of blood, and their influence on hemodynamics. This book represents the first iteration to provide such a work. Normal exercise responses divided into muscle function, bioenergetics, and respiratory, cardiac and blood/vascular function; Fitness, training, exercise testing and limits to exercise; Exercise responses in different environments; Beneficial effects of exercise rehabilitation on ageing and in the prevention and treatment of disease states; Rarely addressed issues such as the influence of exercise on endothelium, vasomotor control mechanisms, coagulation, immune function and rheological properties of blood and their influence on hemodynamics.

Book Metabolic Responses to Supramaximal Exercise and Training

Download or read book Metabolic Responses to Supramaximal Exercise and Training written by Clare L. Weber and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The primary aim of this thesis was to investigate the gender-specific responses to supramaximal cycling and to examine the changes in anaerobic and aerobic metabolism that occur in response to high-intensity interval training (HIT). All subjects in the present experiments were untrained, healthy young adults aged between 18 and 35 yr. Cycle ergometry was used for all experimental test procedures and training programs. The accumulated oxygen (AO2) deficit was used to quantify the production of adenosine triphosphate (ATP) via anaerobic metabolism during supramaximal cycling. In addition, pulmonary oxygen uptake measured at the onset of exercise was described using mathematical modeling to determine the rate response of the aerobic energy system during exercise. The purpose of experiment one was to examine the test-retest reliability of the maximal accumulated oxygen deficit (MAOD) measured at 110% and 120% of peak oxygen uptake for cycling in seven untrained male and seven untrained female subjects. After one familiarization trial, all subjects performed two MAOD tests at a power output corresponding to 110% and two tests at 120% of peak oxygen uptake in random order. MAOD was calculated for each subject as the difference between the estimated AO2 demand and the AO2 uptake measured during the exercise bout. The meanplus or minusstandard error time to exhaustion (TE) for the group was not significantly different between trial one (226plus or minus13 s) and trial two (223plus or minus14 s) of the 110% test. Likewise, the difference in the TE between trial one (158plus or minus11 s) and trial two (159plus or minus10 s) was not significant for the 120% test. The intra-class correlation coefficients for the TE were 0.95 for the 110% test and 0.98 for the 120% test. The mean MAOD value obtained in trial one (2.62plus or minus0.17 L) was not significantly different from the mean value obtained in trial two (2.54plus or minus0.19 L) for the 110% test. Additionally, the mean values for the two trials did not differ significantly for MAOD (2.64plus or minus0.21 L for trial one and 2.63plus or minus0.19 L for trial two) in the 120% test. The intra-class correlation coefficients for MAOD were 0.95 for the 110% test and 0.97 for the 120% test. All intra-class correlation coefficients were significant at p less than 0.001. When conducted under standardized conditions, the determination of MAOD for cycling was highly repeatable at both 110% and 120% of peak oxygen uptake in untrained male and female subjects. The results observed in experiment one suggest that the MAOD may be used to compare the anaerobic capacity (AC) of men and women and to examine changes in the contribution of the anaerobic energy systems before and after training. Experiment two examined the gender-specific differences in MAOD before and after 4 and 8 wk of HIT. Untrained men (n=7) and women (n=7) cycled at 120% of pre-training peak oxygen uptake to exhaustion (MAOD test) pre-, mid-, and post-training. A post-training timed test was also completed at the MAOD test power output, but this test was stopped at the TE achieved during the pre-training MAOD test. The 14.3plus or minus5.2% increase in MAOD observed in males after 4 wk of training was not different from the 14.0plus or minus3.0% increase seen in females (p greater than 0.05). MAOD increased by a further 6.6plus or minus1.9% in males and this change was not different from the additional 5.1plus or minus2.3% increase observed in females after the final 4 wk of training. Peak oxygen uptake measured during incremental cycling increased significantly (p less than 0.01) in male but not in female subjects after 8 wk of training. Moreover, the AO2 uptake was higher in men during the post-training timed test compared to the pre-training MAOD test (p less than 0.01). In contrast, the AO2 uptake was unchanged from pre- to post-training in female subjects. The increase in MAOD with training was not different between men and women suggesting an enhanced ability to produce ATP anaerobically in both groups. However, the increase in peak oxygen uptake and AO2 uptake obtained in male subjects following training indicates improved oxidative metabolism in men but not in women. It was concluded that there are basic gender differences that may predispose males and females to specific metabolic adaptations following an 8-wk period of HIT. Increases in AO2 uptake during supramaximal cycling demonstrated in men after training led to the hypothesis that peak oxygen uptake kinetics are speeded in male subjects with short-term HIT. It was suggested that training does not improve peak oxygen uptake kinetics in women as no change in AO2 uptake was found after 8 wk of HIT in female subjects. The purpose of experiment three was to examine peak oxygen uptake kinetics before and after 8 wk of HIT in six men and six women during cycling at 50% (50% test) and 110% (110% test) of pre-training peak oxygen uptake. A single-term exponential equation was used to model the peak oxygen uptake response (after phase I) during the 50% and 110% tests pre- and post-training. In addition, phase II and III of the peak oxygen uptake response during the 110% tests were examined using a two-term equation. The end of the phase I peak oxygen uptake response was identified visually and omitted from the modeling process. The duration of phase I determined during all experimental tests was not different between men and women and did not change with training in either group. Before training, men obtained a phase II peak oxygen uptake time constant (t2) of 29.0plus or minus3.3 s during the 50% test which was not different to the t2 of 28.8plus or minus2.2 s attained by women. In addition, the t2 determined during the 50% test was unchanged after 8 wk of HIT in both groups. The peak oxygen uptake kinetics examined during the 110% tests before training were well described by a single-term model in all male and female subjects. The t2 determined before training for the 110% test was significantly faster in men than in women. Furthermore, peak oxygen uptake was unchanged in female subjects and the t2 remained unaltered with 8 wk HIT (pre 45.5plus or minus2.2; post 44.8plus or minus2.3 s). In contrast, male subjects achieved a significantly higher peak oxygen uptake after training and the t2 determined for men during the 110% test was faster after training (36.4plus or minus1.6 s) than before training (40.1plus or minus 1.9 s). Improved model fits were obtained with the two-term equation compared to the single-term equation in two of the six male subjects during the 110% test post-training. It was found that the onset of the peak oxygen uptake slow component occurred at a mean time of 63.5plus or minus2.5 s and the t2 was reduced to 18.4plus or minus1.7 s. Using a Wilcoxon Signed Ranks z-test, the t2 described by the single-term equation in the remaining four subjects was determined to be significantly faster after training than before training, thus confirming the results obtained from the original group (n=6) of male subjects. End exercise heart rate (HREE) values obtained during the 50% and 110% tests were not different between men and women. During the 50% test, HREE values were unchanged, whereas HREE was significantly decreased during the 110% test after training in both groups. These data show that HIT might improve oxidative metabolism in men but not in women as reflected by a greater peak oxygen uptake and faster peak oxygen uptake kinetics during supramaximal work rates. We further suggest that the faster peak oxygen uptake kinetics demonstrated in men after training are probably not due to an improvement in cardiac function. Finally, the augmentation of oxidative metabolism during exercise after HIT in men might be dependent on the intensity of the exercise bout at which the peak oxygen uptake response is examined. The findings presented in this thesis suggest that MAOD is a reliable measure in both male and female subjects and can be used to monitor changes in anaerobic ATP production during supramaximal cycling. Moreover, these data suggest that 4 and 8 wk of HIT produce similar changes in anaerobic ATP generation in men and women. Finally, 8 wk of HIT results in the increase of peak oxygen uptake and AO2 uptake as well as the speeding of peak oxygen uptake kinetics during supramaximal cycling in male subjects. There was no evidence to suggest that oxidative metabolism was improved in women after short-term HIT. -- In conclusion, improvement in supramaximal exercise performances should be examined specifically for changes in the anaerobic and aerobic contributions to energy production. In addition, it is suggested that gender should be of primary consideration when designing exercise-training programs where improvement in both anaerobic and aerobic metabolism is required.
