Whole body protein utilization (WBPU), which includes flux (Q), protein synthesis (PS), protein breakdown (PB), and whole body protein balance (WBPB), provides insight regarding muscle mass, a criterion for sarcopenia.
PURPOSE: To characterize yoga's impact on WBPU, body composition and functional measures in healthy (50-65y) women.
METHODS: WBPU and functional measures were compared between women who routinely practiced yoga (YOGA; n=7) and non-active counterparts (CON; n=8).
RESULTS: Q (0.61±0.06 vs. 0.78±0.07, p=0.04), PS (3.07±0.37 vs. 4.17±0.40, p=0.03), PB (2.59±0.48 vs. 3.80±0.48, p=0.05) were lower, and lean body mass higher (64±1 vs. 58±2%, p≤0.01) for YOGA vs. CON, respectively. WBPB, and functional measures were similar.
CONCLUSIONS: Routine yoga practice influenced WBPU in healthy older women. Study findings are novel and provide a basis for future investigations evaluating long-term benefits of yoga as an alternative mode of exercise for maintaining muscle mass in support of active aging.
