项目摘要

We had 480 children from the first to sixth grade of elementary school divided into 4 groups in every grade. In each grade, three groups(A, B, C)were experimental groups and the other(D)was a control group. The former practiced for 3 weeks, and 6 days per week, with three different types of dynamic balance movement. All children were examined by the balance meter in terms of the most appropriate age to get practice.The results of this experiments suggested that the optimal period for learning the dynamic balance movement might be existed in early elementary school years for both sexes. But, the effectiveness of practice in this experiment was lower than tlat of Kobayashi's. Therefore, it is thought that the trainability of dynamic balance ability is much higher in the latter term of infancy(5 years old).The result of this experiment and the discrepancies of the optimum time to learn the walking on stil'ts, and the crouching start which was previously reported indicate that the best tim … More e to learn the dynamic balance movement is shifted to the higher grades of the elementary school, as the necessity of keeping the balance with the center of gravity line falling outside of the base of support, gets larger.We had 180 boys from the forth grade of elementary school through third grade of high school divided into 2 groups in every grade. In each grade, one group was an experimental group and the other was a control group, The former trained for 8 weeks, and 3 days per week, with isokinetic muscle exercise for the muscles of the thigh and arm. All subjects were examined by the Cybex 11 in terms, of the muscle strength and endurance at various angular velocities(Oﾟ 60ﾟ 120ﾟ 180ﾟ 240ﾟ 300ﾟ/s).From this studies, we conclude that the best time to train the muscle strength is at about the 13 years for boy, muscle endurance is at about 12 yearsThe results of these studies suggested that the physical abilities such as muscle endurance, they were found that the effect of training and practice were more considerable among the age group whose physical maturing were remarkable than other age groups.

我们有480名小学一年级到六年级的孩子，每个年级被分成4组。每个年级有三组(A、B、C)为试验组，另一组(D)为对照组。前者训练3周，每周6天，有三种不同类型的动态平衡动作。所有儿童都接受了平衡仪的测试，以确定练习动态平衡动作的最佳年龄。实验结果表明，无论男女，学习动态平衡动作的最佳时期可能都存在于小学早期。但本实验的练习效果低于小林的练习效果，因此认为幼儿后期(5岁)动态平衡能力的可训练性更高。本实验的结果与以往报道的最佳踩踏和下蹲开始时间的差异表明，…的最佳训练时间是在幼儿后期(5岁)更多的动态平衡动作被转移到小学较高的年级，因为保持重心落在支撑底座外的平衡的必要性越来越大。从小学四年级到高中三年级的180名男生每年级分成两组。每个年级一组为试验组，另一组为对照组，试验组训练8周，每周训练3天，进行大腿和上臂肌肉等速肌力训练。对所有受试者进行了Cybex 11测试，测试了不同角速度下的肌肉力量和耐力(Oﾟ60ﾟ120ﾟ180ﾟ240ﾟ300ﾟ/S)。结果表明，男生在13岁左右训练肌肉力量的最佳时机是13岁左右，肌肉耐力训练的最佳年龄在12岁左右。较少
