Lower extremity muscle mass predicts functional performance in mobility-limited elders.
This study examined the influence of lower extremity body composition and muscle strength on the severity of mobility-disability in community-dwelling older adults. ⋯ These data suggest that lower extremity muscle mass is an important determinant of physical performance among functionally-limited elders. Such findings may have important implications for the design of suitable strategies to maintain independence in older adults with compromised physical functioning. Additional studies are warranted to assess the efficacy of lifestyle, exercise or therapeutic interventions for increasing lean body mass in this population.
