Cross-sectional analysis examines muscle health components and their relation to gait speed in older adults, highlighting clinical relevance.

Key Points

The study aims to clarify the relationships between muscle health components and gait speed in older adults, specifically comparing upper- and lower-limb indicators.
Cross-sectional analysis involving 284 community-dwelling adults aged ≥ 65 years.
Measurements included handgrip strength, knee extension strength, arm and leg muscle mass, and usual gait speed.
Linear regression models adjusted for age, sex, and body mass index examined associations with gait speed.
Knee extension strength showed the strongest association with gait speed (standardized β = 0.37, 95% CI 0.23–0.51).
Upper-limb muscle-specific strength (MSS) and lower-limb MSS were associated with gait speed (β = 0.28, 95% CI 0.15–0.40 and β = 0.32, 95% CI 0.21–0.44 respectively).
In a combined model, both upper-limb MSS (β = 0.18, 95% CI 0.05–0.31) and lower-limb MSS (β = 0.27, 95% CI 0.16–0.39) were independently associated with gait speed.
