Document Summary
Ability to perform dynamic exercise involving large muscle groups at moderate-to-high intensity for prolonged periods (acsm 2000) * could ask how to do vo2max calculation in text book. Vo2max is the most valid measure of the cardiorespiratory systems functional capacity. Vo2max reflects: maximal ability of cardiorespiratory system to deliver o2 and nutrients to muscles used, ability of muscles to use them. Hr fails to increase with increasing workload. Rer 1. 15 (respiratory exchange ratio) shouldn"t be here. Rpe 17 on borg 6 to 20 scale. 50 ml/min change with increasing workload (plateau attained) * get plateau for vo2 and heart rate at max/ really intense work rates. Athletes can sometime be able to endure more lactate, greater than 8mmol. Rer- ratio btwn oxygen consumption and carbon dioxide production doesn"t always work ex. Absolute vo2 discrete volume of o2 consumption expressed in l/min or ml/min. * use vo2 peaks in young children and older adults.
