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

Purpose: The American College of Sports Medicine has stated that aerobic: training needs to occur at a minimum threshold intensity of 50% VO2max for most healthy adults and at 40% VO2max 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

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 …
