BACKGROUND
This study compared the effects of plyometric training (PT) and virtual training (VT) on physical and functional performance.
METHODS
Fifty-five moderately-trained women participated in this randomized, controlled, prospective study. The subjects were randomly assigned to VT (N.=20), PT (N.=18), and control (CG, N.=17) groups. The VT was performed using the Your Body Shape Fitness Evolved 2012 exergame in an Xbox360/Kinetic environment. The PT was based on the methods used in previous studies. Both interventions were performed 3 times per week for 8 weeks. Participants in the CG were not submitted to any type of intervention. Physical performance (fitness and athleticism levels) was assessed using the Nike+ Kinetic Training exergame in an Xbox360/Kinetic environment. Functional performance was assessed using the shuttle run (SR), triple hop test (THT), and six-meter timed hop test (STHT).
RESULTS
Postintervention fitness and athleticism levels were significantly greater in VT (P<0.001 and P=0.009) and in PT (P<0.001 and P=0.003) than baselines values. Only VT postintervention fitness level was significantly greater compared to CG (P=0.03). Postintervention SR values were significantly lower than baselines values in all groups (P<0.001). VT (P=0.08) and PT (P=0.006) postintervention values were significantly lower compared to CG. Postintervention THT values were significantly greater than baselines values in VT and PT (P<0.001). VT (P=0.04 - dominant limb) and PT (P=0.003 - dominant limb; and P=0.03 - non-dominant limb) postintervention values were significantly greater compared to CG. Postintervention STHT values were significantly lower than baselines values in VT (P<0.001), PT (P<0.001) and CG (P=0.01-0.02). PT postintervention dominant (P=0.01) and non-dominant (P=0.03) limb values were significantly lower compared to CG.
CONCLUSIONS
Both VT and PT are beneficial for improving physical and functional performance. Therefore, VT might be a new tool that can be used for physical exercise practice and conditioning training in moderately-trained women.
背景
本研究比较了增强式训练（PT）和虚拟训练（VT）对身体和功能表现的影响。
方法
55 名中等训练水平的女性参与了这项随机、对照、前瞻性研究。受试者被随机分配到 VT（N=20）、PT（N=18）和对照组（CG，N=17）。VT 使用 Xbox360/Kinetic 环境中的 Your Body Shape Fitness Evolved 2012 运动游戏进行。PT 基于以前研究中使用的方法。两种干预措施每周进行 3 次，持续 8 周。CG 中的参与者没有接受任何类型的干预。使用 Nike+Kinetic Training 运动游戏在 Xbox360/Kinetic 环境中评估身体表现（健身和运动水平）。使用穿梭跑（SR）、三跳测试（THT）和六米定时跳测试（STHT）评估功能表现。
结果
与基线值相比，VT（P<0.001 和 P=0.009）和 PT（P<0.001 和 P=0.003）的干预后健身和运动水平显著提高。只有 VT 干预后的健身水平与 CG 相比（P=0.03）显著更高。所有组的 SR 值均低于基线值（P<0.001）。与 CG 相比，VT（P=0.08）和 PT（P=0.006）干预后的 SR 值显著更低。VT（P=0.04-优势肢）和 PT（P=0.003-优势肢；和 P=0.03-非优势肢）干预后的 THT 值与 CG 相比显著更高。与基线值相比，VT（P<0.001）、PT（P<0.001）和 CG（P=0.01-0.02）的干预后 STHT 值均显著降低。PT 干预后的优势（P=0.01）和非优势（P=0.03）肢体值与 CG 相比显著降低。
结论
VT 和 PT 都有益于提高身体和功能表现。因此，VT 可能是一种新的工具，可用于中等训练水平女性的身体锻炼实践和调节训练。
