Are There Sex Differences in Balance Performance after a Short-Term Physical Intervention in Seniors 65+? A Randomized Controlled Trial

A systematic review and meta-analysis of studies demonstrated a relationship between sex and balance determinants in seniors; however, no study has focused on sex-related differences in static and dynamic balance performance after a physical intervention as primary interest. The aim was to investigate sex differences in the static and dynamic balance performance after a 4-week physical intervention based on yoga in seniors 65+ years of age. Five-hundred participants (234 males, 266 females) were assessed with the Tinetti Balance Assessment Tool in pre-and post-testing. The experimental group (122 males, 140 females) underwent the intervention, while the control group (112 males, 126 females) ran their usual daily program. ANCOVA model was used for the statistical evaluation of the results. No sex differences were found in balance performance after a short-term physical intervention in seniors 65+ years of age. At the same time, a significant positive shift was demonstrated in performance in both static and dynamic balance.
