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

有一些学习者在体育课上很少提高自己的运动技能。学习者的运动技能较差，这是因为他们在运动控制方面的笨拙。他们笨手笨脚的原因以及如何有效地提高他们的运动技能都没有得到揭示，因此日本的体育教师在指导学习者方面存在一些困难。于是，我考察了笨手笨脚的大学生在运动学习、视觉能力和身体素质方面的挫折。结果如下：1)笨拙的学生不擅长短跑、从跑到跳、投球或预测投球轨迹的顺序动作，他们害怕跨栏、跳跳箱等障碍物。2)学生的眼睛/手协调等视觉能力低于平均水平。3)学生的身体素质较差，如跑50米、部分卷曲等。

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.
