Validation Of A New Method For Estimating Vo2max Based On Vo2 Reserve, David P. Swain, James A. Parrott, Anna R. Bennett, J. David Branch, Elizabeth A. Dowling

Human Movement Studies & Special Education Faculty Publications

Purpose: The American College of Sports Medicine's (ACSM) preferred method for estimating maximal oxygen consumption (V̇O_2max) has been shown to overestimate V̇O_2max, possibly due to the short length of the cycle ergometry stages. This study validates a new method that uses a final 6-min stage and that estimates V̇O_2max from the relationship between heart rate reserve (HRR) and V̇O₂ reserve. Methods: A cycle ergometry protocol was designed to elicit 65–75% HRR in the fifth and sixth minutes of the final stage. Maximal workload was estimated by dividing the workload of the final stage by …

Dietary Supplements And Sports Performance: Introduction And Vitamins, Melvin H. Williams

Human Movement Studies & Special Education Faculty Publications

Sports success is dependent primarily on genetic endowment in athletes with morphologic, psychologic, physiologic and metabolic traits specific to performance characteristics vital to their sport. Such genetically-endowed athletes must also receive optimal training to increase physical power, enhance mental strength, and provide a mechanical advantage. However, athletes often attempt to go beyond training and use substances and techniques, often referred to as ergogenics, in attempts to gain a competitive advantage. Pharmacological agents, such as anabolic steroids and amphetamines, have been used in the past, but such practices by athletes have led to the establishment of anti-doping legislation and effective testing …

Characterizing Consumer Motivation As Individual Difference Factors: Augmenting The Sports Interest Inventory (Sii) To Explain Level Of Spectator Support, Daniel C. Funk, Daniel F. Mahony, Lynn L. Ridinger

Human Movement Studies & Special Education Faculty Publications

The central focus of this study was to examine how individual difference factors could be used to explain various levels of consumer support for a specific sport property. The present study extends the Sport Interest Inventory (SII) in order to enhance current understanding of consumer motives in relation to sport in general and women's competitive sport in particular. Confirmatory factor analysis confirmed the 12-item Sport Interest Inventory, measuring 14 individual difference factors related to spectator interest in soccer. Multiple Linear regression analysis revealed that five motivational characteristic--(a) sport interest, (b) team interest, (c) vicarious achievement, (d) role modeling, and (e) …

Vo2 Reserve And The Minimal Intensity For Improving Cardiorespiratory Fitness, David P. Swain, Barry A. Franklin

Human Movement Studies & Special Education Faculty Publications

Purpose: The American College of Sports Medicine has stated that aerobic: training needs to occur at a minimum threshold intensity of 50% VO_2max for most healthy adults and at 40% VO_2max for those with a very low initial fitness. Recently, the concept of VO₂ reserve (% VO₂R, i.e., a percentage of the difference between maximum and resting VO₂ has been introduced for prescribing exercise intensity, This analysis was designed to determine the threshold intensity for improving cardiorespiratory fitness expressed as %VO₂R units. Methods: Previous studies in healthy subjects (N = 18) that …

Is There A Threshold Intensity For Aerobic Training In Cardiac Patients?, David P. Swain, Barry Franklin

Human Movement Studies & Special Education Faculty Publications

Purpose: Recent guidelines have recommended the use of a percentage of oxygen uptake reserve ((V) over dot O₂R) for prescribing aerobic exercise intensity for cardiac patients. Moreover, these guidelines suggest that a threshold intensity may exist, below which no improvement in peak oxygen uptake ((V) over dot O-_2peak) occurs, The purpose. therefore. was to translate the intensity of aerobic exercise in previous training studies using cardiac patients into %(V) over dot O₂R units, and determine whether a threshold intensity exists, Methods: Twenty-three studies, using 28 groups of aerobically trained cardiac patients. were identified in …

Pumping Dietary Iron: Implications For Aerobic Endurance Exercise, Melvin H. Williams
