一般来讲,绝大多数同学两手的灵活性都有明显差异。普遍是右手比左手灵便。体育课中训练的大多数是以单侧运动为主的项目,同学们往往喜欢用自己较灵活的右手投掷垒球或打篮球、乒乓球等。这样,不灵活的左手自然锻炼得更少,身体左侧肌肉更加僵硬,不利于身体的全面协调发展。 In general, the vast majority of students have obvious differences in the flexibility of both hands. Generally, the right hand is more handy than the left hand. The majority of physical education training is based on unilateral sports-based projects, students often like to use their more flexible right-handed throw softball or playing basketball, table tennis and so on. In this way, the inflexible left hand naturally less exercise, the body muscles on the left more rigid, not conducive to the overall coordinated development of the body.
