Key result
Higher levels of physical fitness, including VO2 max, handgrip strength-to-body weight ratio, one-leg standing time, and walking speed, were significantly inversely associated with systemic arterial stiffness in older adults.
Why the study?
Previous studies examining associations between physical fitness measures and arterial stiffness reported inconsistent results.

Higher physical fitness, including VO2 max, relative handgrip strength, balance, and walking speed, is significantly associated with lower arterial stiffness in older adults.

Pulse-wave velocity (PWV) is a widely used clinical marker of arterial stiffness. Associations between several physical fitness measures and arterial stiffness have been examined. However, these results were inconsistent. Therefore, we conducted a cross-sectional study to assess the relationship between various physical fitness parameters and arterial stiffness in older adults. From January 2014 to December 2015, 1500 participants (men, n = 587; mean age, 71.78 ± 5.10 years) in South Korea were enrolled in the study. Koreans aged >65 years who agreed to participate in the study were enrolled. Individuals who were unable to exercise because of underlying conditions were excluded. VO2 max (mL/kg/min), handgrip strength (kg), handgrip strength (kg)/body weight (kg) ratio, one-leg standing time (s), and 10-meter walking speed (m/s) were measured. The brachial-ankle pulse wave velocity (baPWV) was measured using a VP-1000 instrument. VO2 max (mL/kg/min), handgrip (kg)/body weight (kg) ratio, one-leg standing time (s), and 10-meter walking speed (m/s) were significantly inversely associated with baPWV. This association was consistent even after adjusting for confounding factors. Our study revealed a significant association between various aspects of physical fitness and arterial stiffness. This study suggests that physical fitness is a useful predictor of arterial stiffness in older adults.

Yoo et al. (2022) conducted a cross-sectional in Arterial stiffness (n=1,500). Higher physical fitness (VO2 max, handgrip strength/body weight ratio, one-leg standing time, walking speed) vs. Lower physical fitness (lowest tertile) was evaluated on Brachial-ankle pulse wave velocity (baPWV) (Beta -94.95, p=0.02). Higher levels of physical fitness, including VO2 max, handgrip strength-to-body weight ratio, one-leg standing time, and walking speed, were significantly inversely associated with systemic arterial stiffness in older adults.
