摘要
The purpose of this study was to examine the association between stride length and body composition, physical fitness level, and activity of daily living (ADL) in the Korean elderly population. This study included 98 Korean elderly subjects aged 65-82 years. These subjects visited the health promotion center at Gyeong-Ju, Gyeongsangbuk-Do, Korea, where stride length, body composition, physical fitness level, and ADL were assessed in August 2011. Subsequently, the association of stride length with body composition, physical fitness level, and ADL were assessed using multivariate logistic regression analysis adjusted for gender, age, and body mass index (BMI). The odds ratio (OR) [95% confidence interval (CI)] of a stride length across the 6 min walk groups was 8.042 (range, 3.132-20.650; p < 0.001) for the greater level, compared to the smaller level. The OR (95% CI) of a stride length across the grip strength groups was 3.071 (range, 1.307-7.218; p = 0.010) for the greater level, compared to the smaller level. The OR (95% CI) of a stride length across the gait speed groups was 0.429 (range, 0.088-0.566; p = 0.002) for the greater level, compared to the smaller level. The OR (95% CI) of a stride length across the ADL groups was 2.571 (range, 1.086-5.834; p = 0.031) for the greater level, compared to the smaller level. The differences in the OR (95% CI) of a stride length among the following groups were insignificant: fat free mass (FFM), percent body fat, sit ups, sit and reach, and Standing on 1 foot with open eyes, compared to the greater level (p > 0.05). We conclude that body composition is not closely related to a greater stride length. However, the association between physical fitness level such as distance covered in a 6 min walk, grip strength, gait speed, and ADL was evident.
