Understanding Submaximal Cardiovascular Mechanics
The cardiovascular response to low-intensity submaximal work is a generally consistent surrogate for maximal exercise capability. During moderate walking, the heart rate escalates in proportion to muscular oxygen requirement. Individuals with superior aerobic capacity exhibit a lower heart rate response because their left ventricle is capable of pumping more blood per beat (higher stroke volume). The Rockport formula uses this physiological relationship to accurately estimate maximal oxygen capacity without exposing the athlete to extreme exhaustion.
