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).

This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty-eight physically active males were used to evaluate the modified Astrand-Ryhming Nomogram as a predictor of Maximal oxygen consumption. In addition to the modified Astrand Bicycle Ergometer test of Maximal Oxygen Uptake and the Mitchell, Sproule and Chapman Maximal Oxygen Intake test, body height, weight and surface area as well as fitness scores and time run on the Johnson, Brouha and Darling test of Physical Fitness were studied. Oxygen uptake tests were performed in definite sequences and subjects were equally divided by chance into all possible orders. Gas analyses were performed using a Beckman E-2 oxygen analyser and a Godart Capnograph carbon dioxide analyser and checked by the Scholander method. Results were analysed with Pearson Product-moment correlation coefficients and analysis of variance. Results obtained were: In terms of liters per minute, the modified Astrand-Ryhming nomogram produced significant correlations (p = .01) of O .67 with the Mitchell, et al test, and 0.62 with the modified Astrand Bicycle test. The treadmill test correlated 0.51 with the maximal bicycle test. With body weight partialled out the correlations were again significant (p = .01) and equal to 0.53> 0.47» and 0.39 respectively. Fitness scores on the Johnson, Brouha and Darling test produced significant correlations (p = .01) of O .38 with the treadmill test, O .46 with the maximal bicycle test, and 0.55 with the predicted test in terms of liters per minute. Corresponding values in milliliters per kilogram of body weight per minute were 0 . 46 , 0.55» and O .67 respectively. Height correlated significantly with the Astrand Bicycle test (p = .01), the Mitchell, et al test (p = .05) and the predictive test (p = .05) in terms of liters per minute. Weight and body surface area produced equivalent results which were significant with all three of the oxygen consumption tests in terms of liters per minute (p = .01) and with the two actual tests (negative relationship) in terms of milliliters per kilogram of body weight per minute (p * .05). Fitness scores and endurance measured on the Johnson, et al test did not correlate significantly with height, weight, or body surface area. Within the limits of this study, the following conclusions have been made: 1. For the population studied, the Mitchell, Sproule and Chapman Maximal Oxygen Intake test and the modified Astrand-Ryhming Nomogram for Prediction of Maximal Oxygen Uptake, yielded significantly higher mean values than the modified Astrand Bicycle Ergometer test of Maximal Oxygen Uptake. 2. Statistically equivalent means were obtained on the modified Astrand- Ryhming Nomogram and the Mitchell, Sproule and Chapman Maximal Oxygen Intake test. 5. The Astrand-Ryhming Nomogram produced a significantly greater variance than did the modified Astrand Bicycle Ergometer test and the Mitchell, Sproule and Chapman test. 4. The Astrand-Ryhming Nomogram was able to predict maximal oxygen intake values on the modified Astrand Bicycle Ergometer test and the Mitchell, Sproule and Chapman test as well as the latter tests were able to predict values on each other. 5. As measured by the Johnson, Brouha and Darling test of Physical Fitness, the Astrand-Ryhming Nomogram was able to predict physical fitness as well as the modified Astrand Bicycle Ergometer test and significantly better than the Mitchell, Sproule and Chapman test. 6. Body weight and surface area produced equivalent significant correlations with the three test of maximal oxygen uptake in terms of liters of oxygen consumed per minute. 7. Body height, weight and surface area did not show any significant relationships with the Johnson, Brouha and Darling fitness index or endurance. 8 . Correlation coefficients involving body weight and body surface area proved to be virtually identical.

Available in PDF, EPUB and Kindle. Book excerpt: "In this fifth edition of Principles of Exercise Testing and Interpretation, as in earlier editions, we attempt to develop conceptual advances in the physiology and pathophysiology of exercise, particularly as related to the practice of medicine. The underlying theme of the book continues to be the recognition that the most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a byproduct of exercise metabolism. Thus, appropriate cardiovascular and ven- tilatory responses are required to match those of muscle respiration in meeting the energy demands of exercise. As depicted by the logo on the book cover, normal exercise performance requires an efficient coupling of external to internal (cellular) respiration. Appropriate treatment of exercise intolerance requires that patients' symptoms be thought of in terms of a gas exchange defect between the cell and the environment. The defect may be in the lungs, heart, peripheral or pulmonary circulations, the muscles themselves, or there may be a combination of defects. Thus, we describe the pathophysiology in gas transport and exchange that affect any site in the cardio- respiratory coupling between the lungs and the muscles. We illustrate how cardiopulmonary exercise testing can provide the means for a critical evaluation by the clinician-scientist of the functional competency of each component in the coupling of cellular to external respiration, including the cardiovascular system. To achieve this, clinical cases are used to illustrate the wide spectrum of pathophysiology capable of causing exercise intolerance"--Provided by publisher.

Available in PDF, EPUB and Kindle. Book excerpt: In the last several years, Clinical Exercise Testing has become an increasingly important tool for patient evaluation in clinical medicine due to a growing awareness of the limitations of traditional resting cardiopulmonary measurements. Emphasizing scientific and technological advances and focusing on clinical applications for patient diagnosis and management, this volume provides a comprehensive interdisciplinary review of clinical exercise testing, concentrating on Cardiopulmonary Exercise Testing (CPET). 25 reader-friendly chapters discuss important topics, including the physiologic responses to exercise in normal subjects, in the aged and in various disease states; the set-up of an exercise lab; the methodology and protocols used for clinical exercise testing; and an integrative approach to the interpretation of CPET results. CPET in heart failure, deconditioning, COPD, ILD, pulmonary vascular disease, neuromuscular disease, and asthma is thoroughly discussed. Clinical applications including pulmonary and cardiac rehabilitation, heart and lung transplantation evaluation, unexplained exertional dyspnea assessment, evaluation for lung resection and lung volume reduction surgery, and impairment-disability evaluation are also covered in detail. Additional chapters on clinical exercise testing in children, during pregnancy and the postpartum, and in other systemic disorders complete this extensive publication. Written by well-respected experts, this volume will be a valuable resource for a wide audience including pulmonologists, cardiologists, pediatricians, exercise physiologists, rehabilitation specialists, nurse clinician specialists, and respiratory therapists.
