摘要：The purpose of this study was to evaluate the long-term and repeated bout effects of static stretching (SS) program in older active adults, and to clarify the effects of flexibility on muscle strength of knee and trunk. The subjects were healthy active adults (aged 67–80 years). The intervention group (n = 7) performed the SS program for 1 year and an additional period of 2 years. The SS program was configured to target the body’s major muscle groups, and the exercises were performed five times a week. The peak torques in extension and flexion of knee and trunk (isokinetic contraction 60°/ sec) were obtained from isokinetic dynamometer, and sit and reach test was assessed yearly. As a result, flexibility was increased by 31% during the first SS intervention (period of 1 year), and muscle strength were also increased by about 10% to 17%. Additionally, a higher effect was obtained by the second SS intervention (period of 2 years). We found a significant correlation between the magnitude of changes in flexibility and muscle strength. Therefore, the repetition of an SS program is important for improving or maintaining flexibility and muscle strength in older active adults.
