Concerning balance training, the most effective design of several load dimensions (e. g., training frequency, volume) is unclear. Thus, we determined the effects of different balance training volumes on dynamic balance in healthy children. Three groups of 20 children (age: 11.0±0.7 years; 47% females) were randomly assigned to a balance training group using a low or a high training volume or an active control group that performed regular physical education lessons. All groups trained for 8 weeks (2 sessions/week), whereby balance training volume amounted to 4 min/session and 18-24 min/session for the low- and high-volume group, respectively. Pre- and post-training, balance performance was assessed using the Lower Quarter Y-Balance Test and the Timed-Up-and-Go Test. Fifty-five children completed the study and significant Test x Group interactions were detected for both outcome measures in favor of the two balance training groups. Additionally, improvements in the high-volume group were significantly larger for some measures (Y-balance test anterior reach distance: <.001, =.94; Timed-Up-and-Go time: =.003, =.81) compared to the low-volume group. The results indicate that balance training is effective to improve balance performance in healthy children and it seems that a 36-48 min/week compared to an 8 min/week training volume provides additional effects.
关于平衡训练，几个负荷维度（如训练频率、训练量）中最有效的设计尚不清楚。因此，我们确定了不同平衡训练量对健康儿童动态平衡的影响。将三组20名儿童（年龄：11.0±0.7岁；47%为女性）随机分配到使用低训练量或高训练量的平衡训练组或进行常规体育课的积极对照组。所有组均训练8周（每周2次），低训练量组和高训练量组的平衡训练量分别为每次训练4分钟和18 - 24分钟。在训练前和训练后，使用下肢Y平衡测试和定时起立行走测试评估平衡能力。55名儿童完成了研究，两项结果测量均检测到显著的测试×组交互作用，表明两个平衡训练组更具优势。此外，与低训练量组相比，高训练量组在某些测量指标上的改善更为显著（Y平衡测试前伸距离：<.001， =.94；定时起立行走时间： =.003， =.81）。结果表明，平衡训练对于提高健康儿童的平衡能力是有效的，而且与每周8分钟的训练量相比，每周36 - 48分钟的训练量似乎能带来额外的效果。
