Acute Resistance Training May Have Lasting Benefit to Middle-Aged Adults

Abstract

Age-related declines in physical function can be mitigated with resistance training (RT), but most adults do not regularly exercise. We aimed to identify the magnitude and duration of benefits after RT in the Stay Strong, Stay Healthy (SSSH) program. A total of 27 adults (Repeaters n = 15; Summer Only n = 12), aged 60.7 ± 4.8 years, completed the same 8 weeks of SSSH in the summer and Repeaters continued in fall and spring months. Independent and paired t -tests and repeated-measures ANOVAs were used to test changes in survey responses and physical performance over 10 months. Both groups were similar at baseline ( p > .07) and improved from pre- to post-summer for health surveys scores, 30 second-sit-to-stand, timed-up-and-go, and sit-n-reach ( p ≤ .02). Additionally, Repeaters (measured data) and Summer Only (2.3% modeled decline) maintained those improvements 10 months later. Participation in 8 weeks of SSSH significantly improved physical strength and function and these improvements may last up to a year.
