Sarcopenia, the age-related loss of skeletal muscle mass and function is associated with risk of falls/fractures and mortality. Physical inactivity and inadequate protein intake are lifestyle factors that may contribute to the development of sarcopenia. Weight-adjusted skeletal muscle index (wSMI), grip-strength (GRIP) and gait-speed (GAIT) are utilized to diagnose sarcopenia. The PURPOSE of the study was to evaluate the relationships among indicators of sarcopenia, physical activity and protein intake in older adults. METHODS: In 112 subjects (81W/31 M, 67±6.3 years) gait speed, grip strength, body composition, and habitual physical activity were measured. wSMI [skeletal muscle mass (SMM)÷body mass] was also calculated. In a subset of 52 subjects, habitual dietary intake was determined. RESULTS: MODMIN/DAY PA was significantly correlated with wSMI (r= 0.306) and ASM (r=-0.310). MVPA was significantly correlated with GAIT (r=0.195). There was a significant correlation between TPI and ASM (r= 0.436) and ASM/m2 (r=0.45). CONCLUSION: These data show that PA and protein intake are associated with better scores for some indicators of sarcopenia. Thus, increased physical activity and protein intake may represent effective strategies for decreasing the risk of sarcopenia.
