Abstract Aims Aging is associated with declines in muscle strength and physical function, sleep plays a crucial role maintaining musculoskeletal health. This cohort study, based on the China Health Retirement Longitudinal Study (CHARLS), aims to explore relationship between characteristics performance middle-aged elderly individuals. Methods A total of 2,998 participants from CHARLS were included, baseline data 2011 survey follow-up 2015 survey. Nighttime napping patterns assessed, changes duration over time categorized. Physical functioning was assessed through handgrip strength, chair stand test, walking appendicular skeletal mass, SPPB scores. Multiple linear regression restricted cubic spline models employed analyze effects Results After adjusting for all confounding factors, multifactor liner indicated that durations exceeding 90 min reduced grip ( β = -0.39, 95% CI: -1.43, -0.01, P < 0.05) longer test times 0.59, 0.18, 0.99, 0.01). The clear U-shaped nap (non-linear 0.05), whereas no such observed test. In subgroup analyses addressing significant it found older than 65 years, males, those low levels daily activity exhibited greater sensitivity function. joint analysis showed compared individuals less 6 h nighttime napping, 6–8 30–90 0.63, 0.06, 1.20, 0.05). Additionally, naps 1.44, 0.68, 2.21, Conclusions Both insufficient excessive at linked diminished performance. For adults, approximately 50 may be potentially optimal strength. These findings highlight importance proper management, particularly men years old levels, preserving function reducing risk mobility decline.
