摘要

体育活动在儿童成长中起着至关重要的作用,学校成为促进儿童体育活动的关键场所。本研究的目的是验证高强度循环训练在学校常规体育课上的效果。对115名11-14岁的儿童(71名男孩,34名女孩)进行了评估。参与者被分为对照组(男孩:N = 47;女生:N = 16)和实验组(男生:N = 24;女孩:N = 18)。除了正常的体育课外,实验组还在课程开始时进行了为期八周的高强度循环训练,每周两次。进行了前后测试。心肺(20米穿梭跑试验)和一组强度变量进行评估。脂肪质量百分比作为体细胞指标。20米穿梭跑测试存在显著的时间效应,但不存在时间X性别、时间X组和时间X体重状态的交互作用。相反,强度变量呈现显著的时间X组交互作用(组间显著差异)。脂肪质量百分比存在显著的时间效应,但X组交互作用不显著。数据显示,在体育课中增加高强度的循环训练可以显著提高儿童的肌肉健康表现,但心肺健康可能没有同样程度的改善。高强度的循环训练计划(在学校的常规体育课程中进行)似乎在身体健康参数和减少脂肪量百分比方面表现出积极和显著的影响。

The influence of a specific high intensity circuit training during physical education classes in children’s physical activity and body composition markers
Physical activity plays a paramount role on children growth and schools emerged as a key setting for pro- moting physical activity during childhood. The aim of this study was to verify the effects of a high intensi- ty circuit training performed during regular physical education classes at schools. One hundred and five children aged 11–14 years (71 boys and 34 girls) were evaluated. The participants were split into a control group (boys: N = 47; girls: N = 16) and an experimental group (boys: N = 24; girls: N = 18). Besides the normal physical education classes, the experimental group also performed a high intensity circuit training for eight weeks, twice a week, at the beginning of the lesson. A pre- post-test was performed. Cardiorespiratory (20 m shuttle run test ) and a set of strength variables were evaluated. Percentage of fat mass was used as a somatic indicator. The 20 m shuttle run test presented a significant time effect, but not a time X sex, time X group, and time X weight status interactions. Conversely, the strength variables presented a significant time X group interaction (significant differences between groups). Percentage of fat mass presented a significant time effect, but not a significant time X group interaction. Data showed that adding a high intensity circuit training to physical education classes would result in a significant increase in muscular fitness performance in children, but cardiorespiratory fitness may not present the same magnitude of improvement. High in- tensity circuit training programs (performed during regular physical education classes at schools) seem to present a positive and significant effect in physical fitness parameters as well as reducing the percentage of fat mass.
