Cardiorespiratory Fitness and Muscular Strength on Arterial Stiffness in Older Adults.

Purpose: To evaluate the independent and combined associations of cardiorespiratory fitness (CRF) and muscular strength (MS) with arterial stiffness (AS), a strong predictor of cardiovascular disease, in older adults.

Methods: This cross-sectional study included 405 older adults (mean age, 72 yr). Cardiorespiratory fitness was assessed by time (s) to complete a 400-m walking test and MS by maximal handgrip strength (kg).
