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 2017 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the accuracy of non-maximal tests: the Talk Test (TT), Rating of Perceived Exertion (RPE) extrapolation, Rockport Walking Test (RWT) and non-exercise VO2max prediction equation for predicting exercise capacity (VO2max and VT). Subjects (N=20) were 18-50 yrs. of low to moderate fitness level. Subjects performed three exercise sessions. Test 1 was a maximal incremental test to measure VO2max and VT. Test 2 was a submaximal incremental exercise test without respiratory gas exchange measurements, using the TT and RPE. Test 3 was the RWT. Also, VO2max was calculated using the non-exercise prediction equation of Matthews et al. (1997). The results showed that there was no significant difference between measured VO2max and predicted VO2max using the non-exercise equation, extrapolation to RPE19 and the RWT. However, measured VO2max was significantly less than predicted VO2max using extrapolation to RPE 20 (p≤0.05). There was no significant difference (p>0.05) between the VO2 at VT, the LP, and EQ stages of the TT, and at RPE13 and RPE14. However, the VO2 at RPE 15 was significantly higher than VO2 at VT (p≤0.05). In conclusion, the results showed that the non-maximal methods could be used as primary methods for exercise prescription and outcome assessment.

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.

Download or read book Improving Exercise Testing Methods and Interpretation in Human Health and Diseases written by Mathieu Gruet and published by Frontiers Media SA. This book was released on 2023-11-28 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise testing is a versatile tool for health purposes. When used in combination with specific devices and sensors, it can provide valuable diagnostic and prognostic information in a wide range of populations. Exercise testing outcomes are also useful for training prescriptions and defining responses to clinical trials evaluating interventions. Whole-body maximal tests (e.g., cardiopulmonary exercise testing), field tests (e.g., walking tests), and modalities isolating a muscle group (e.g., isokinetic endurance testing) all have their advantages and limits and should be viewed as complementary. Recent advances in wearable technology and artificial intelligence provide unique opportunities to broaden the application of these tests and facilitate their interpretation. In the meantime, the clinimetric properties of some widely used exercise tests are still poorly documented in several clinical populations, which hampers optimal diagnosis and management. Moreover, most exercise tests used in clinical practice are suffering from a lack of ecological validity and there is a need to develop and valid new testing modalities that best mimic daily life functioning. This Research Topic aims to extend our knowledge regarding the validity and clinical utility of various exercise testing modalities and facilitate their interpretation. This topic supports a multimodal approach to exercise testing and welcomes reports investigating either whole-body or local muscle testing. Submission of research combining different exercise modalities and investigating their potential links are particularly encouraged. Inter-disciplinary research with studies integrating concepts, tools, and data from various disciplines like exercise physiology, biomechanics, and psychology are of particular interest for this Research Topic. This topic is not restricted in terms of age, medical conditions, or type of disease but manuscripts must have clear implications for human health.

Download or read book An Accurate VO2max Non exercise Regression Model for 18 to 65 Year old Adults written by Danielle I. Bradshaw and published by . This book was released on 2003 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (Rp = .91 and SEEp = 3.63 mLʺkg-£ʺmin-£); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (aged 18-65) with a similar cardiorespiratory fitness level. Based on standardized ¿-weights the PFA variable (0.41) was the most effective at predicting VO2max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO2max in adult men and women.

Download or read book DEVELOPMENT AND VALIDATION OF A REGRESSION MODEL TO ESTIMATE VO2 Max FOR OLDER ADOLESCENTS FROM PACER 20 M SHUTTLE RUN PERFORMANCE written by Matthew S Hanna and published by . This book was released on 2017 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PACER provides a convenient and relatively low cost assessment of aerobic fitness. The PACER is less expensive and more readily available than stationary or portable metabolic systems, can be completed in a condensed area of 20 meters, and can be administered to large groups. The PACER is the preferred (or default) test of aerobic fitness for the FITNESSGRAM[registered] youth fitness program. The purpose of this study was to develop a regression model to estimate VO2 max from PACER performance, age, gender, and body mass or body mass index in 17- to 18-year-old males and females. Additionally, several previously published equations were cross-validated to allow for comparison between prediction models. A secondary purpose was to examine the criterion-referenced validity of the models. Participants included 22 females and 26 males aged 17 to 18 years. Height and weight were assessed and percent body fat was measured with air displacement plethesmography via the BOD POD. Participants completed a maximal treadmill test following the Bruce protocol. The PACER 20-m multi-stage shuttle run was completed following FITNESSGRAM[registered] procedures. Multiple linear regression analysis was used to predict VO2 max from the number of laps completed on the PACER, age, gender, and body mass or body mass index. Estimates of VO2 max from previously published prediction models were cross-validated and the standard error of estimate (SEE) and total error (TE) were calculated. Comparison of the two error estimates identified the effect of systematic overestimation or underestimation on prediction accuracy. Mean scores for VO2 max for males (41.9 ± 9.9) and females (33.1 ± 6.7) were lower than the 2010 FITNESSGRAM[registered] Healthy Fitness Zone (HFZ) standards (males [greater-than or equal to] 44.2 ml.kg-1.min-1 and females [greater-than or equal to] 38.6 ml.kg-1.min-1). Only 27% of female participants (n = 6) and 42% of male participants (n = 11) had a measured VO2 in the HFZ. The only variable that significantly contributed to estimation of VO2 max was PACER laps completed. The model developed on the current sample was: VO2 max = 20.41012 + (PACER laps * 0.41304). The correlation between measured VO2 max and VO2 max predicted from this equation was high (R = .89). All cross-validated prediction equations produced high correlations between measured and estimated VO2 max (R [greater-than or equal to] .81). The prediction model developed in the current study and the L©♭ger et al. (1988) model produced the highest correlations (r = .89) between measured and estimated VO2 max, the lowest standard errors of estimate (4.36 ml.kg-1.min-1 and 4.43 ml.kg-1.min-1), and the lowest TE (4.36 ml.kg-1.min-1 and 4.81 ml.kg-1.min-1). Criterion-referenced analysis was used to examine the classification accuracy of the models for three categories (HFZ, Needs Improvement – Some Risk [NISR], and Needs Improvement – High Risk [NIHR]) and two categories (HFZ and Needs Improvement [NI]). Proportion of agreement for the three category analysis was moderate (Pa = .73) for the model developed in the current study. When classification was condensed into two classification zones (HFZ and NI), Pa increased (Pa = .88). The remaining cross-validated models had a low to moderate Pa (.52 - .66) under the three category format, and moderate Pa (.66 - .77) under the two category format. In conclusion, the prediction model developed in the current study developed on an older adolescent sample provides an accurate estimate of VO2 max. The variable of laps completed on the PACER was the only significant contributor to the equation. Most of the previously published equations were notably less accurate than this new model. The current prediction model also produced accurate classification of fitness levels into the Healthy Fitness Zone or Needs Improvement categories.

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.
