Setbacks in Motor Learning and Perceptual-Motor Abilities of Motor Skill Underachievers

有一些学习者很少在体育课上提高他们的运动技能。学习者的运动技能较差，因为他们在运动控制方面的笨拙。日本的体育教师在指导学习者时存在一定的困难。于是，我考察了笨拙的大学生在运动学习、视觉能力和身体素质方面的挫折。结果表明：1）笨拙的学生不擅长短跑，不擅长从跑到跳的连续动作，不擅长扔球或预测投射球的轨道，他们对障碍物有恐惧感，障碍物是跨栏，跳箱等。2）学生的视觉能力如眼/手协调能力低于平均水平学生们跑50米、部分卷缩等身体素质较差。

There are some learners who rarely improve their motor skills in physical education classes. The learners' motor skills are poor because of their clumsiness in motor control. The reason why they are clumsy and how to improve their motor skills effectively are not revealed, so physical education teachers in Japan have some difficulties in instructing the learners. Thereupon, I examined setbacks in motor learning, visual abilities and physical fitness of clumsy university students. The results were as the followings.1) The clumsy students were not good at sprinting, the sequential movements from running to jumping, throwing a ball or anticipating the orbit of a projected ball, and they had fear about obstacles, which were hurdles, vaulting boxes and so on.2) The students' visual abilities such as eye/hand coordination were below-average.3) The students had poor physical fitness such as running 50 meters and partial curl-up.
