Book Validity of Submaximal Cycle Ergometry for Estimating Aerobic Capacity

Available in PDF, EPUB and Kindle. Book excerpt: The accepted method for determining maximal oxygen consumption is collection and analysis of expired gases which has been limited to the research laboratory. Although a variety of tests may be more practical, the relative safety, validity, and reliability has been a concern. To simplify the Wahlund/Astrand-Rhyming protocols to enhance test precision as well as making it reasonable for the non-technically trained test administrator, a procedure has been developed that allows early selection of the most appropriate test work load. A computerized version makes it possible for non-trained personnel to safely administer this test for estimating aerobic capacity. This study critically evaluates the relationship between estimates of maximal oxygen consumption by a specific cycle ergometer protocol and (1) values obtained by the criterion method employing indirect calorimetry and exhaustive treadmill exercise, and (2) the very high and very low levels of aerobic capacity that are implicit for competitive endurance athletes and for documented sedentary adults, respectively.

Book The Prediction of Maximal Oxygen Uptake from a Perceptually regulated Exercise Test PRET

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Borg 6-20 rating of perceived exertion (RPE) scale is a common measure reported during exercise testing and training, and is usually taken as a response measurement to provide a subjective assessment of exercise intensity. A lesser used application of the scale is for regulating exercise intensity, referred to as its 'production mode'. Recent research on this topic initiated by Eston et al. (2005) has led to a novel application of this procedure as a means of predicting an individual's maximal oxygen uptake ( O2max) via a perceptually-regulated exercise test (PRET). The PRET could play a significant role in guiding exercise prescription and monitoring cardiorespiratory fitness levels in situations where the normal heart rate response is affected. The aim of this thesis is to develop further and test the integrity of the PRET technique. Firstly, a review of the evidence on the validity and reliability of the Borg RPE scale when used to regulate exercise intensity in healthy and unhealthy adults is presented, as to-date, no scholarly publication has synthesised the body of knowledge on this specific application of the scale. Subsequently, four studies were completed to investigate the effects of different methodological variations on the predictive capabilities of the PRET, including an examination (for the first time) of its utility among heart failure patients (Study 4). Study 1 re-visited the validity and reliability of the PRET technique utilising a modified protocol of differing durations (2 and 4 min bouts), with revised instructions and placing the graded exercise test (GXT) as the final trial during cycle ergometry. Superior results were observed to those reported in previous investigations (Eston et al., 2008; Faulkner et al. 2007; Eston et al., 2006) during the 3 min trial, further reinforcing the validity and reliability of this technique. Accordingly, Study 2 was the first to investigate the reliability and validity of a treadmill PRET protocol with a ceiling intensity of RPE 15, rather than RPE 17, and observed that a safer modified PRET (with practice) provides acceptably valid and reliable predictions of O2max in healthy adults. In addition, Study 3 extended the research thus far by investigating the PRET protocol during cycle exercise, once again with a ceiling intensity of RPE 15, and demonstrated that (with practice) a cycle-based PRET can yield reliable and valid predictions of O2max that compare favourably to previous investigations. Finally, given that the research employing a PRET has unanimously alluded to its likely value in clinical populations among whom heart rate as a physiological response to exercise is affected (e.g. via medication) and precluded as a means predicting O2max, Study 4 investigated the utility of a PRET in a beta-blocked population of heart failure patients. In the event, it was observed that a PRET (up to RPE 15) was too strenuous and needs to be capped at an intensity of RPE 13 in this population. In addition a continuous protocol seemed unsuitable due to its length and it was recommended that a discontinuous PRET protocol be investigated. Future research needs to investigate the utilisation of the PRET (i) in different exercise modes; (ii) determine the optimum number of practice trials required; (iii) whether a discontinuous or continuous protocol is more appropariate; (iv) whether the extrapolation should be made to RPE 19 or 20 and; (v) whether the PRET can be employed succesfully in other clinical populations.

Book Validation of a Quick Submaximal Test of Maximal Oxygen Intake

Download or read book Validation of a Quick Submaximal Test of Maximal Oxygen Intake written by Alfred Eugene Coleman and published by . This book was released on 1972 with total page 17 pages. 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).

Book Submaximal Cycle Ergometry as a Predictor of Maximal Aerobic Capacity InWomen on Oral Contraceptives

Download or read book Submaximal Cycle Ergometry as a Predictor of Maximal Aerobic Capacity InWomen on Oral Contraceptives written by Jannell C. MacAulay and published by . This book was released on 1999-12-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicted maximal aerobic capacity (VO2max), using submaximal exercise tests, is used to evaluate fitness for job performance, especially within the military. Women who use oral contraceptives experience a rhythmic variation of circulating synthetic hormones that can influence submaximal exercising heart rate. The purpose of this study was to examine the validity and reliability of two submaximal heart rate-dependent cycle ergometry exercise tests, one used by the Air Force (AF) and one suggested by the American College of Sports Medicine (ACSM), for women using oral contraceptives. Eighteen healthy and fairly active women, aged 19-22 years, completed a maximal treadmill exercise test with indirect calorimetric determination of VO2max followed two days later by submaximal testing. Each of the three tests were conducted in both the quasi-luteal (Q-L) phase (the second week of the active pill) and the quasi- follicular (Q- F) phase (the last 3 days of placebo administration). VO2max was lower (by 1.1 + 0.63 ml/kg/min) in Q-L than in Q-F (Q-L = 38.2+ 1.1 ml/kg/min, Q-F = 39.3 1 1.1 ml/kg/min, P = 0.055). Comparison of VO2max predicted by the AF test to the true maximal value revealed a slight, statistically non-significant (1.5%) overestimation in the Q-L phase (AF = 38.8 1 1.8 ml/kg/min vs Max = 38.2 1 1.1 ml/kg/min, P = 0.3) and a larger underestimation (5%) in the Q-F phase (AF = 37.41 1.8 ml/kg/min vs Max = 39.3 11.1 ml/kg/min, P = 0.06). Between the two phases, the predicted values of the AF test were significantly different (Q-L = 38.8 1 1.8 ml/kg/min, Q-F = 37.4 1 1.8 ml/kg/min, P = 0.02). The ACSM test underestimated VO2max in the Q-L (3%) phase and significantly
