一般生徒におけるスターティングブロックの設置方法の違いが疾走パフォーマンスに及ぼす影響 : 男女差に着目して

The purpose of the present study was to obtain basic data on sprint performance by students in physical education classes for 3 types of crouching start (CS)—bunch start (BS), medium start (MS), and elongated start (ES)— and standing start (SS), and to examine differences between males and females. The results are summarized as follows.1) Over a 50-m running distance, the start method had no significant influence on performance among males in terms of most of the parameters analyzed. However, for BS, stride length in the first 1—2 steps was significantly shorter than for the other start methods.2) Female\u27s ES and SS were seen, and the running speed was seen compared with MS and BS and a high tendency was seen intentionally. For ES, the average stride and average start speed were intentionally greater than for MS and BS in males. The stride patterns during the distance and start phase were similar compared with other start methods before and behind ES and SS, and the possibility that CS (ES) was able to be accomplished in the condition similar to SS was thought.The above findings suggest that a graded learning method for CS in physical education classes would be beneficial for males, and that BS should be excluded in the initial stage of learning, whereas for females it is recommended that ES be employed to acquire a longer stride more easily in the introduction stage
