保护与帮助是体操教学与训练的特点,也是教学与训练必不可少的手段和教学方法之一,在体操教学与训练中占有极其重要的地位。适当地运用保护与帮助的时机,有助于减轻学生的身体负担,消除顾虑,增强学习信心,从而加速建立正确的动作概念,掌握动作与技术。帮助的时机运用不当,不但起不到助力的作用,而且会有碍动作。如帮助需要升高重心的动作时,应在抛高(上起)过程中帮助加力,这样形成的力等于两人的合力,动作效果会最佳。如果失掉这个时机,待练习者身体(或某部位)开始下降再帮助,既费力又不可能完成动作,达不到预期的目的。有些动作对帮助时机的要求非常严格,如团身前空翻,当练习者两臂上摆后,帮助者必须一手及时插放其腹前帮助翻转,过早必然妨碍摆臂,过晚则错过时机不能及时给予助力,失去了帮助的意义。下面就几个实例对帮助时机进行一下粗浅分析。 例1 单杠径直角悬垂摆动屈伸上 Protection and help are the characteristics of gymnastics teaching and training. It is also one of the indispensable means and teaching methods of teaching and training, occupying an extremely important position in gymnastics teaching and training. Appropriate use of the timing of protection and help to help reduce the physical burden on students, to eliminate concerns and enhance learning confidence, so as to accelerate the establishment of the correct concept of movement, master the action and technology. Improper use of the opportunity to help not only does not help but also hinders action. Such as helping to need to raise the center of gravity action, should be in the process of throwing (from) to help force, this force is equal to the resultant force of the two, the action will be the best. If this opportunity is lost, it will be difficult and impossible for the practitioner’s body (or a part) to start descending and then help it to complete its intended purpose. Some actions on the timing of the request is very strict, such as the group before the flip, when the practitioners on both arms, the helper must promptly insert their abdomen in one hand to help flip, prematurely impede the swing arm, too late to miss the opportunity Can not give aid in time, lost the meaning of help. Here are a few examples to help you analyze the timing. Example 1 straight bar straight swing swing over the stretch
