WHY? SV? HR? SPMD 202 Transition from Rest to Exercise • At the beginning of exercise there is a rapid increase in HR, SV, and CO (w/in first second of exercise). • If work rate is constant, steady-state is reached within 2-3 min. 2 SPMD 202 Plowman & Smith. Exercise Physiology for Health, Fitness, and Performance SPMD 202 Recovery from Exercise • Recovery from short-term, low-intensity exercise is generally rapid. --varies from individual to individual --well-trained recover faster than untrained • Recovery from long-term exercise is much slower. SPMD 202 Incremental Exercise • HR & CO increase in direct proportion to oxygen consumption. • In moderately or untrained individuals, SV does not appear to increase beyond a workload of ~40% VO2max (continues more “linearly” with trained individuals).
