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.

This book was released on 2021-12-03 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2017 in the subject Engineering - Computer Engineering, grade: 100.00/100.00, Çukurova University, language: English, abstract: The purpose of this thesis is twofold. The first purpose is to develop new hybrid feature selection-based maximal oxygen uptake (VO2max) prediction models using for the first time the double and triple combinations of maximal, submaximal and questionnaire variables. Several machine learning methods including Support Vector Machine, artificial neural network-based and tree-structured methods combined individually with three feature selectors Relief-F, minimum redundancy maximum relevance (mRMR) and maximum-likelihood feature selector (MLFS) have been applied for model development. The second purpose is to design a new ensemble feature selector, which aggregates the consensus properties of Relief-F, mRMR and MLFS to produce more robust decisions about the set of relevantly identified VO2max predictors and to create more accurate prediction models. Using 10-fold cross validation on three different datasets, the performance of prediction models has been evaluated by calculating their multiple correlation coefficients (R’s) and root mean squared errors (RMSE’s). The results show that compared with the results of the other regular feature selection-based models in literature, the reported values of R and RMSE of the hybrid models in this thesis are considerably more accurate. Furthermore, prediction models based on the proposed ensemble feature selector outperform the models created by individually using the Relief-F, mRMR or MLFS, achieving similar or ideally up to 12.46% lower error rates on the average.

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.

Download or read book Prediction of Vo2max with Submaximal and Questionnaire Variables written by Yucel Eser and published by LAP Lambert Academic Publishing. This book was released on 2015-11-24 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maximal oxygen uptake (VO2max) refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. The purpose of this thesis is to develop accurate VO2max prediction models using submaximal and questionnaire variables. Regression methods such as Support Vector Machines (SVM), Multilayer Perceptron (MLP) and Multiple Linear Regression (MLR) have been used for developing VO2max prediction models. The performance of prediction models has been evaluated by calculating their multiple correlation coefficients (R's) and standard error of estimates (SEE's). The results show that the accuracy of VO2max prediction models based on submaximal and standard non-exercise variables could be significantly improved by including questionnaire variables in prediction models. The results of SVM models have been also compared with the ones obtained by MLP and MLR and it turned out that SVM-based VO2max prediction models perform better (i.e. yield lower SEE's and higher R's) than the prediction models developed by other regression methods.

This book was released on 2010-07 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study determined the accuracy of non-exercise VO2max prediction equations with measured maximal oxygen uptake values in long distance runners. Eight male volunteer ULM cross country athletes performed a VO2max test and had their body composition measured utilizing the three site Jackson-Pollock skinfolds equation. The participants completed a modified version of the physical activity rating questionnaire to assess physical activity for the previous month. Activity levels included values for sedentary lifestyle (PA-R = 0) to running 60 miles per week (PA-R = 14). Non-parametric (Spearman's rho) correlations were used to analyze relationships between measured VO2max values and non-exercise prediction equations. The correlation between measured VO2max values and a multiple regression equation, featuring body mass index and the runners' physical activity rating (PA-R) was significant (r = .762) at the p

This book was released on 2015 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to evaluate the effect of using the Rating of Perceived Exertion (RPE) on the accuracy of the Rockport 1- mile walk test. Eighty-eight subjects ranging in age and fitness levels performed a Rockpmt 1- mile walk test and a Balke maximal oxygen consumption (V02max) test on the treadmill. During both tests the subject's RPE was recorded each stage of the V02mnx test and every 200 meters of the Rockpmt test. Maximal oxygen consumption was predicted by using linear regression. The accuracy of the equations was determined using multiple regression (R2 between V02max predicted fi·om 1 mile walk time and RPE with measured V02max· The Rockport lJ equation was slightly less accurate compared to the original Rockport, but is simpler as it only used 2 variables.
