: This study aimed to compare the effects of Xbox Kinect Sports (XKS) regarding Nintendo Switch Sports (NSS) and an inactive control group (CG) on body composition (body fat percentage, BFP; and fat-free mass) and physical performance (maximal isometric handgrip strength, MIHS; 30-s chair stand, 30-S; timed up-and-go, TUG; sit-and-reach; and 2-min step) in physically inactive older females. A randomized controlled trial study was conducted with three parallel groups: XKS (n = 13), NSS (n = 14), and CG (n = 16) considering three weekly 60-min sessions for 12 weeks with pre- and post-assessments. A two-factor mixed analysis of variance (ANOVA) model with repeated measures was performed to measure the time × group effect. Multiple comparisons revealed significant differences in BFP (F = 6.12; = 0.005; ηp = 0.226, large effect), 30-S (F = 20.7; = 0.000; ηp = 0.496, large effect), TUG (F = 10.0; = 0.000; ηp = 0.323, large effect), sit-and-reach (F = 37.3; = 0.000; ηp = 0.640, large effect), and 2-min step (F = 9.85; = 0.000; ηp = 0.319, large effect) in favor of XKS regarding NSS and CG. The intragroup results only present in XKS a significant decrease in BFP ( = 0.02; d = 0.98) and significant improvements in the 30-S ( = 0.000; d = 1.88), TUG ( < 0.01; d = 2.00), sit-and-reach ( = 0.003; d = 2.58), and 2-min step ( = 0.004; d = 1.05). training using XKS significantly decreases BFP and improves 30-S, TUG, sit-and-reach, and 2-min step in physically inactive older females.
本研究旨在比较Xbox Kinect Sports（XKS）与Nintendo Switch Sports（NSS）以及非活动对照组（CG）对身体活动不足的老年女性身体成分（体脂百分比，BFP；以及去脂体重）和身体机能（最大等长握力，MIHS；30秒椅子站立试验，30-S；计时起立行走试验，TUG；坐位体前屈；以及2分钟踏步试验）的影响。进行了一项随机对照试验研究，分为三个平行组：XKS组（n = 13）、NSS组（n = 14）和CG组（n = 16），为期12周，每周进行三次60分钟的训练课程，并在训练前后进行评估。采用重复测量的双因素混合方差分析（ANOVA）模型来测量时间×组间效应。多重比较显示，在BFP（F = 6.12；P = 0.005；ηp = 0.226，大效应）、30-S（F = 20.7；P = 0.000；ηp = 0.496，大效应）、TUG（F = 10.0；P = 0.000；ηp = 0.323，大效应）、坐位体前屈（F = 37.3；P = 0.000；ηp = 0.640，大效应）和2分钟踏步试验（F = 9.85；P = 0.000；ηp = 0.319，大效应）方面，XKS组相对于NSS组和CG组有显著差异。组内结果仅显示XKS组的BFP显著降低（P = 0.02；d = 0.98），30-S（P = 0.000；d = 1.88）、TUG（P < 0.01；d = 2.00）、坐位体前屈（P = 0.003；d = 2.58）和2分钟踏步试验（P = 0.004；d = 1.05）有显著改善。使用XKS进行训练可显著降低身体活动不足的老年女性的BFP，并改善30-S、TUG、坐位体前屈和2分钟踏步试验的结果。
