Adolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD).
A single-group pre-post design was conducted to assess the impact of a newly developed Wii protocol in adolescent girls attending school in a low income community of Cape Town, South Africa. Sixteen participants (aged 13-16 years) with p-DCD (≤16th percentile on the MABC-2 test) were recruited. Participants received 45 min Wii training for 14 weeks. Outcome measures included the six-minute walk distance and repeated sprint ability. Information on heart rate, enjoyment and perceived exertion ratings were also collected.
Significant improvements in aerobic and anaerobic fitness were observed. The participants reported high enjoyment scores and low perceived exertion ratings. The graded Wii protocol was easily adaptable and required little resources (space, equipment and expertise) to administer.
The findings provide preliminary evidence to support the use of the graded Wii protocol for promoting physical fitness in adolescent girls with p-DCD. Further studies are needed to confirm these results and to validate the clinical efficacy of the protocol in a larger sample with a more robust design.
与运动能力高的同龄人相比，运动能力低的青少年参与体育活动较少，且身体素质往往较差。因此，有必要找到提高这一人群身体素质的新方法。已有研究表明，主动式电子游戏（AVG）可改善运动表现，但关于其对身体素质影响的研究有限。本研究的目的是探讨分级Wii方案对可能患有发育性协调障碍（p-DCD）的青春期女孩身体素质的影响。
采用单组前后测设计，评估一种新开发的Wii方案对南非开普敦一个低收入社区上学的青春期女孩的影响。招募了16名患有p-DCD（在MABC-2测试中百分位≤16）的参与者（年龄13 - 16岁）。参与者接受了为期14周、每次45分钟的Wii训练。结果测量指标包括6分钟步行距离和反复冲刺能力。还收集了心率、享受程度和主观用力程度评分等信息。
观察到有氧和无氧适能有显著改善。参与者报告享受程度得分高，主观用力程度评分低。分级Wii方案易于调整，实施所需资源（空间、设备和专业知识）很少。
研究结果提供了初步证据，支持使用分级Wii方案来提高患有p-DCD的青春期女孩的身体素质。需要进一步研究来证实这些结果，并在设计更完善的更大样本中验证该方案的临床疗效。
