The purpose of this study was to examine changes in physical activity and fitness variables in members of 8 volunteer families after 3 months of home use of the Wii Fit™ interactive video game. Pre and postintervention measurements were obtained from 21 subjects relative to physical activity (5 days of accelerometry), aerobic fitness (graded treadmill test), muscular fitness (push-ups), flexibility (sit-and-reach test), balance (composite equilibrium score), and body composition (body mass index and % body fat). Use characteristics of the Wii Fit™ device were also determined. A series of 2 (age group) × 2 (time) repeated measures analyses of variance were conducted to assess changes over time and between adults and children. Three months of home Wii Fit™ use revealed no significant age group × time interactions or main effects of group or time for daily physical activity, muscular fitness, flexibility, balance, or body composition. An age group × time interaction (p = 0.04) was observed in peak VO2 (ml·kg(-1)·min(-1)) with children displaying a significant (p = 0.03) increase after 3 months of Wii Fit™ use, whereas adults showed no significant (p = 0.50) change. Daily Wii Fit™ use per household declined by 82% (p < 0.01) from 21.5 ± 9.0 min·d(-1) during the first 6 weeks to 3.9 ± 4.0 min·d(-1) during the second 6 weeks. Most measures of health-related fitness in this exploratory study remained unchanged after 3 months of home use of the popular Wii Fit™ whole-body movement interactive video game. Modest daily Wii Fit™ use may have provided insufficient stimulus for fitness changes.
本研究旨在探讨 8 个志愿家庭的成员在使用 Wii FitTM 互动视频游戏 3 个月后，其身体活动和健康变量的变化。21 名受试者进行了干预前后的测量，包括身体活动（5 天加速度计）、有氧健身（分级跑步机测试）、肌肉力量（俯卧撑）、柔韧性（坐-触测试）、平衡（综合平衡评分）和身体成分（体重指数和%体脂肪）。还确定了 Wii FitTM 设备的使用特点。进行了一系列 2（年龄组）×2（时间）重复测量方差分析，以评估随时间的变化以及成年人和儿童之间的变化。3 个月的家庭 Wii FitTM 使用并未显示出年龄组×时间的交互作用，也没有显示出组或时间对日常身体活动、肌肉力量、柔韧性、平衡或身体成分的主要影响。观察到峰值 VO2（ml·kg(-1)·min(-1)）的年龄组×时间交互作用（p = 0.04），儿童在 Wii FitTM 使用 3 个月后显示出显著的（p = 0.03）增加，而成年人则没有显著的（p = 0.50）变化。每个家庭的日常 Wii FitTM 使用量从第 1 至第 6 周的 21.5 ± 9.0 min·d(-1)下降了 82%（p < 0.01），到第 2 至第 6 周的 3.9 ± 4.0 min·d(-1)。在这项探索性研究中，大多数健康相关的健身指标在家庭使用流行的 Wii FitTM 全身运动互动视频游戏 3 个月后没有变化。适度的日常 Wii FitTM 使用可能不足以刺激健身变化。
