Book Validity of Submaximal Cycle Ergometry for Estimating Aerobic Capacity

Download or read book Validity of Submaximal Cycle Ergometry for Estimating Aerobic Capacity written by and published by . This book was released on 1998 with total page 0 pages. 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 1994 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two hundred and seven subjects (males, n=103; females, n=104) between the ages of 18 and 54 volunteered for this study to determine the accuracy of the USAF submaximal cycle ergometry (SCE) test versus treadmill (TM). The analysis shows that USAF SCE VO sub (2max) estimates are valid for males and females in this age range. For males, baseline SCE underpredicted VO (2max) by 2.2 ml/kg/min, had a moderately high correlation (r=0.85), and acceptably low standard error of the estimate (SEE, 6.7 ml/kg/min). For females, baseline SCE overestimated VO sub (2max) by 2.2 ml/kg/min. For females, correlation was moderately high (r=0.85) with a relatively low SEE (5.5 ml/kg/min, 16.6%). Repeat SCE did not increase accuracy. Adjusting power output to achieve higher steady state heart rates improved correlations and lowered SEE. SCE was more closely related to TM VO sub (2max) than to maximal cycle measures. Finally, 102 subjects completed a YMCA SCE test. For males, the YMCA test overpredicted VO sub (2max). Correlation and SEE were not satisfactory (r=0.63 and SEE=9.8 ml/kg/ min). For females, the YMCA test was equally good or slightly better than the USAF SCE in estimating VO sub 2max. USAF SCE sensitivity was 75%. Specificity was 96%. Suggestions to further improve USAF SCE validity and accuracy are offered. Aerobic capacity, Cycle ergometry, Physical fitness.

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

Download or read book Submaximal Cycle Ergometry as a Predictor of Maximal Aerobic Capacity in Women on Oral Contraceptives written by and published by . This book was released on 1999 with total page 0 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.

Book Validity and Reliability of the YMCA Submaximal Cycle Test Using an Electrically Braked Ergometer

Download or read book Validity and Reliability of the YMCA Submaximal Cycle Test Using an Electrically Braked Ergometer written by and published by . This book was released on 2018 with total page 40 pages. Available in PDF, EPUB and Kindle. 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 The Test Retest Reliability of the United States Air Forces Submaximal Bicycle Ergometry Aerobic Fitness Test

Download or read book The Test Retest Reliability of the United States Air Forces Submaximal Bicycle Ergometry Aerobic Fitness Test written by Frank Allen Glenn and published by . This book was released on 1998-05-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to perform endurance work is dependent on aerobic metabolism. Maximal oxygen consumption (VO2max) defines aerobic capacity and quantifies an individual's capability for aerobic resynthesis of adenosine triphosphate (6,51). VO2max is the primary indicator of aerobic fitness, cardiovascular health, and endurance performance (2,22,39,51,93). When assessing aerobic capacity, a type of exercise must be chosen which involves a large group of muscles and be of sufficient intensity and duration to cause an adjustment in the cardio-respiratory system to the level of exercise ?7,74,9 1). The typical exercise modes include treadmill running and walking, endurance runs and walks for time or distance, stationary cycling, arm cranking, bench stepping, and swimming (10,66,74). To determine aerobic capacity, a maximal test (direct measurement) or a submaximal test (estimation or prediction) is used to obtain a VO2mx value (2,31,91).

Book Submaximal Aerobic Fitness Evaluation

Download or read book Submaximal Aerobic Fitness Evaluation written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase 1A: Twenty-five healthy males, 18 to 30 years of age, completed this study to cross-validate the Banister-Legge (B-L) submaximal cycle ergometry test. The B-L nomogram for untrained and trained subjects and the USAF CE significantly underestimated the measured VO2 sub max. The B-L nomogram was not recommended as a protocol for use by the USAF. Phase 1B: Fifty-eight males and 61 females, 18 to 48 years of age, completed this study to develop new submaximal cycle ergometer protocols and prediction equations to estimate VO2 sub max. Ramp (registered) and ramp to steady-state (RSS) protocols, six prediction equations for men, and three prediction equations for women were developed. Phase 2: Thirty-one males and 36 females, 18 to 40 years of age, completed this study comparing the 1-mile walk and USAF CE test for estimating VO2 sub max. There were no significant differences between the VO2 sub max estimated by these tests and the measured VO2 sub max A subset of this population (17 males and 20 females) also completed R and RSS tests. There were no significant differences between the measured and estimated VO2 sub max for the 1-mile walk, the USAF CE, the six new equations for men, and one of three new equations for women.

Book Fitness Measures and Health Outcomes in Youth

Download or read book Fitness Measures and Health Outcomes in Youth written by Institute of Medicine and published by National Academies Press. This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.

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.
