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

Human Movement Sciences & 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 …
