Book excerpt: Purpose: To test the effect of using an electrically braked ergometer on the validity and reliability of the YMCA submaximal cycle test. Methods: 22 male and 13 female subjects ages 19 to 31 completed one maximal treadmill test and four submaximal cycle tests to measure and estimate VO2max, respectively. The maximal tests involved recording heart rate and VO2 during graded exercise until volitional fatigue; an actual max was verified when two out of the following criteria: respiratory Exchange Ratio> 1.1, VO2 plateau (150 ml/min increase in VOsub2/sub during final stage), and achievement of 90% age-predicted HR max (or completed a validation stage). The submaximal tests were conducted in accordance with ACSM guidelines (10supth/sup ed.). Measured and predicted VOsub2max/sub measurements were compared between tests using repeated measures ANOVA and Pearson correlations. Results: The treadmill VOsub2max/sub protocol yielded significantly higher values (50.3 ± 7.7 mL/kg/min) than the YMCA submax protocol using a friction-braked (40.8 ± 5.5 mL/kg/min) and electrically braked ergometer (38.8 ± 4.5 mL/kg/min). Furthermore, estimated VOsub2max/sub using the friction-braked ergometer was higher than that observed using the electrically braked ergometer. There were similar reliability coefficients between the friction-braked (R = 0.63) and electrically braked (R = 0.52) ergometers. Lastly, a moderately strong (R = 0.74) relationship was observed between actual VOsub2max/sub and prediction error (VOsub2max/sub - estimated VOsub2max/sub). Conclusion: Both Monark and Viasprint ergometers severely underestimated VOsub2max /subin a sample of generally fit, young individuals. Future investigations should explore the possible relationship between higher aerobic fitness and accuracy of predicting VOsub2max

Book excerpt: Maximal oxygen consumption (VO2max) serves as an accurate predictor of an individual's cardiorespiratory fitness (CRF) and is typically measured via a maximal treadmill test. Due to costs, age and health limitations, submaximal tests (such as the YMCA test) can be administered to estimate VO2max values. There is much dispute regarding the validity and accuracy of these tests as estimators of CRF. This study investigated the effect of using an electrically-braked cycle ergometer on the validity of the YMCA cycle ergometer test. A population of healthy, fit college-aged individuals (n = 20) were administered one maximal treadmill test to obtain actual VO2max, and four submaximal tests following the YMCA protocol (2x Monark ergometer and 2x Viapsrint ergometer) to estimate VO2max. Overall this study observed estimated VO2max values obtained from the YMCA protocol underpredicts VO2max (regardless of whether the test is performed on either an electrically-braked or a mechanically-braked ergometer. Neither submaximal test showed a strong correlation (Monark: R = 0.53 & Viasprint: R = 0.30) with actual VO2max but the Monark test was more valid and reliable than the Viasprint test due to the lack of a significant validity and reliability coefficient for the electrically-braked ergometer protocol. Additionally, both submaximal tests showed relatively low reliability coefficients (Monark: R = 0.50 R; Viasprint: R = 0.42). The findings from this study indicate that the YMCA submaximal test needs to undergo improvements in order to serve as an accurate predictor of VO2max in this population.

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.

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

There was a time when exercise testing was largely limited to cardiologists, but no more. Ex- cise testing, which providesinformationon tness, the risk of coronarydisease, and all around vitality, is now being performed in the of ces of primary care physicians across the United States. Although there is a signi cant risk in some populations, a careful doctor who takes the trouble to become knowledgeable in exercise physiology and the pat- physiologyof coronary artery disease can use exercise testing to improve his ability to give excellent, preventive medicine.
