Heart rate recovery as an assessment of cardiorespiratory fitness in young adults.

ABSTRACT:

Background

Cardiorespiratory fitness, typically measured as peak oxygen uptake (VO_2peak) during maximal graded exercise testing (GXT_max), is a predictor of morbidity, mortality, and cardiovascular disease. However, measuring VO_2peak is costly and inconvenient and thus not widely used in clinical settings. Alternatively, postexercise heart rate recovery (HRRec), which is an index of vagal reactivation, is a valuable assessment of VO_2peak in older adults and athletes. However, the validity of HRRec as a clinical indicator of cardiorespiratory fitness in young, sedentary adults, who are a rapidly growing population at risk for developing obesity and cardiovascular disease, has not been fully elucidated.
