项目摘要

Two main studies were included in this research project. First, daily physical activity levels of 71 fifth-grade children of elementary school in Tohoku district, including those from a rural area and city, were investigated in the autumn. The participants were asked to wear a heart rate monitor for 12 day-time hours and to give a self-report on their activities.Although no significant differences were found in mean HR among children with two living conditions and between genders, some tendencies were identified. The time that children of the rural area spent in going to school was 30 minutes longer than that of children living in a city, and there was a significant gender difference in the amount of after-school activities ; boys spent 40 minutes longer than girls. The mean total time of high intensity activities (*150 bpm) taken by children who were categorized active was about an hour, and this was longer than that of those who were categorized inactive.Activity levels of children w … More ere also measured in snowing season. The mean total time of high intensity activities the children had after school was decreased to between one third and one sixth of the autumn. It is suggested from the preferable amount of activity that skiing in the PE class can be one of the better sport activities for school curriculum.Second, the effect of practice on motor performance (50m run, long jump and throwing) was examined. In the first year, 65 third-grade and 74 fifth-grade children were asked to practice all these skills for four to five weeks, three to four days a week, under teacher's instruction. Records of respective events were measured before and after practice. The results showed that the rate of improvement was higher in children with relatively low score before practice and of third-grade rather than fifth-grade. In the second year, 93 third-grade and 85 fifth-grade children were asked to practice only one of the three events for eight weeks, three to four days a week, 20 minutes at a time. Significant improvement due to practice was shown in 50m run by third-grade girls as well as long jump and throwing by fifth-grade boys. Less

本研究项目包括两项主要研究。首先，在秋季调查了东北地区小学五年级71名儿童的日常体力活动水平，包括农村和城市。参与者被要求佩戴心率监测器12天的时间，并给自己的activity.Although没有显着差异，发现在两种生活条件的儿童和性别之间的平均HR，一些趋势被确定。农村儿童上学的时间比城市儿童多30分钟，在课外活动的时间上存在显著的性别差异;男孩比女孩多40分钟。被归类为活跃的儿童进行高强度活动（*150 bpm）的平均总时间约为1小时，比被归类为不活跃的儿童长。 ...更多信息也在下雪的季节测量。孩子们放学后高强度活动的平均总时间减少到秋季的三分之一到六分之一。从活动量上看，体育课中的滑雪活动可以作为学校体育课程中较好的体育活动之一。第二，考察了练习对运动成绩（50 m跑、跳远和投掷）的影响。在第一年，65名三年级和74名五年级的孩子被要求在老师的指导下练习所有这些技能，每周三到四天，为期四到五周。在练习前后测量相应事件的记录。结果表明，练习前成绩较低的儿童和小学三年级的儿童比小学五年级的儿童进步率高。在第二年，93名三年级和85名五年级的孩子被要求在八周内只练习三个项目中的一个，每周三到四天，每次20分钟。由于练习，三年级女生的50米跑以及五年级男生的跳远和投掷成绩有了显著提高。少
