This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was designed to permit a comparison of the values obtained on four maximal oxygen consumption tests: the Mitchell, Sproule and Chapman Maximal Oxygen Intake Test, the Taylor, Puskirk and Penschel Treadmill test of Maximal Oxygen Consumption, the modified Astrand Bicycle Ergometer test of Maximal Oxygen Uptake and the modified Astrand-Ryhming Nomogram for the Prediction of Maximal Oxygen Uptake. In addition, an attempt was made to determine the degree of relationship between the predictive-type maximal oxygen consumption test, the determined measures of maximal oxygen consumption as yielded by both of the treadmill tests and the bicycle ergometer test and a test of physical fitness. The Johnson, Brouha and Darling test of Physical Fitness was used to determine a fitness score. A second aspect of the study was an attempt to examine changes in oxygen uptake values on the various tests incurred by additional work after a maximal value had been arrived at on the basis of the criteria established in the test outline. The experimental group was composed of 24 healthy, physically active male students and staff members of the University of Alberta and soldiers from Griesbach Barracks, Edmonton, Alberta. The age range was 17 to 53 years. The testing sequence was based on a permutation design except for the physical fitness test which was administered on the initial visit. A Godart Capnograph carbon dioxide analyzer and a Beckman #E-2 oxygen analyzer were used for the gas analysis and their accuracy was validated by the Scholander method. The mean maximal oxygen consumption values obtained on the Mitchell et al. test, Taylor et al. test and the modified Astrand-Ryhming Nomogram test were found to be significantly larger than the mean obtained on the modified Astrand Bicycle Ergometer test (p = .05). The values (expressed as liters of oxygen consumed per minute) obtained on the modified Astrand-Ryhming nomogram correlated at 0.80 with the physical fitness test, 0.78 with the Mitchell et al. test, 0.72 with the Taylor, Buskirk and Henschel test and 0.65 with the modified Astrand Bicycle Ergometer test. Correlations after body weight was partialled out were of the same magnitude. Of 22 subjects who performed extra worklevels on the Mitchell et al. test after achieving a criterion-designated maximal oxygen uptake, 15 developed a significantly higher value (p = .01). Seven subjects participated in this phase of the study on the Taylor et al. test. Three of the seven developed a significantly higher maximal oxygen consumption value (p = .05). None of the 15 subjects who did extra work on the modified Astrand Bicycle Ergometer test was able to elicit a higher maximal oxygen uptake value. Within the limitations of the study it was concluded that: 1. The treadmill tests and the predictive-type test yielded higher maximal oxygen consumption values than did the modified Astrand Bicycle Ergometer test. 2. The correlation coefficients which resulted from a comparison of the Astrand-Ryhming Nomogram test with the other four tests were not significantly different from the correlations that existed between the maximal tests of oxygen consumption and the fitness score. 5. The Astrand-Ryhming test produced a significantly larger variance than did any of the three direct tests of maximal oxygen consumption. 4. The present criteria used for the establishment of a maximal oxygen consumption value on the two treadmill tests studied do not necessarily provide a maximal estimation of this ability for all subjects.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to validate a submaximal treadmill test for prediction of maximal oxygen consumption in fifteen male college students. This objective was accomplished by comparing maximal oxygen intake values recorded during a maximal treadmill test with those predicted from the submaximal test. Comparisons were also made among the between the true and predicted values and those estimated from the Astrand-Rhyming nomogram. Application of the analysis of variance techniques indicated that no significant difference existed between the criterion and the two predictors. The average error of prediction; however, was 8 percent for the submaximal test and 15 percent for the nomogram. The results of the study indicated that the submaximal test yielded a valid estimate of maximal oxygen intake and is more accurate than several of the commonly used submaximal tests. (Author).

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.
