Abstract

Background/Objectives: This study aimed to compare the effects of Xbox Kinect Sports (XKS) relative to an inactive control group (CG) on cognitive status and physical performance in physically inactive older females. Methods: A randomized controlled trial study was conducted with the following groups: XKS (n = 15) and CG (n = 15), considering three weekly sessions of 60 min for 24 weeks. A two-way mixed analysis of variance with repeated measures was performed. Results: A two-way mixed ANOVA revealed significant time × group interactions for the Mini-Mental State Examination (MMSE) (F(2,18) = 14.8, p = 0.000, ?p2 = 0.292, large effect), Timed Up-and-Go (TUG) (F(2,18) = 19.5, p = 0.000, ?p2 = 0.351, large effect), and Falls Efficacy Scale-International (FES-I) (F(2,18) = 6.55, p = 0.015, ?p2 = 0.154, large effect). No significant interactions were observed for the Berg Balance Scale (BBS) (F(2,18) = 0.998, p = 0.324, ?p2 = 0.027, small effect), Maximal Isometric Handgrip Strength (MIHS) (dominant: F(2,18) = 0.163, p = 0.688, ?p2 = 0.005; non-dominant: F(2,18) = 0.012, p = 0.912, ?p2 = 0.000, small effects), or Maximal Isometric Pinch Strength (MIPS) (dominant: F(2,18) = 0.099, p = 0.756, ?p2 = 0.003; non-dominant: F(2,18) = 0.233, p = 0.632, ?p2 = 0.006, small effects). Conclusions: XKS significantly improves cognitive status measured by the MMSE and physical performance through reduced time in TUG and fear of falling through the FES-I in physically inactive older females. © 2025 by the authors.
