Static balance in young athletes is an important ability that has a relevant influence on their present and future sport performances, as well as on the reduction in risk of injury. The present study reports data collected on three homogeneous groups of 9 years-old athletes (n=10 for each group), whose static balance was monitored every two months during an overall period of six months. At the beginning of the study, all of the children in each of the three groups were performing soccer activity with a frequency (three times a week) that was kept constant during the observation period. During the six months, group 1 maintained only the soccer activity, group 2 also performed swimming activity (twice a week) in parallel with the soccer activity, while group 3 started, at month 2, to perform soccer activity with a break dance course (twice a week). Double leg stance (with eyes open and closed) and single leg stance (on dominant and non-dominant leg) tests were performed using a force platform, and the COP area calculated for each trial. Results show a clear decrease in the "soccer+break dance" players COP area values during the six months, suggesting an improvement in their static balance. The difference was significantly greater with respect to that of soccer players and "soccer+swimming" players. This was evident in all the tests performed starting from two months after the break dance activity began.
年轻运动员的静态平衡是一项重要的能力，它对他们目前和未来的运动表现以及减少受伤风险都有相关影响。本研究报告了在六个月的总体期间内每两个月监测一次的三组同质 9 岁运动员（每组 10 名）的静态平衡数据。在研究开始时，三组中的所有儿童每周进行三次足球活动，在观察期间保持不变。在六个月期间，第 1 组仅维持足球活动，第 2 组在足球活动的同时还进行游泳活动（每周两次），而第 3 组在第 2 个月开始每周两次进行足球活动和霹雳舞课程。使用力平台进行双腿站立（睁眼和闭眼）和单腿站立（优势腿和非优势腿）测试，并计算每次测试的 COP 区域。结果表明，在六个月的时间里，“足球+霹雳舞”运动员的 COP 区域值明显下降，表明他们的静态平衡得到了改善。与足球运动员和“足球+游泳”运动员相比，差异更为显著。从霹雳舞活动开始两个月后进行的所有测试中都可以明显看出这一点。
