중등부 단거리 선수의 100M 질주시 속도 및 가속도 변화 분석

Analysis on Change of Velocity and Acceleration at Full Speed of 100M in Middle School Athletes

&nbsp;&nbsp;The purpose of this study is to analyze the velocity and acceleration in each block, using the 10 lap timer sensor, at full speed of 100M based on 5 male and female athletes in middle school.<BR>&nbsp;&nbsp;The results of this study are as follows:<BR>&nbsp;&nbsp;1. By recording the highest speed at 50M, or a little more late time than in pre-studies in both male and female groups, entire records were found to have a significant loss by late arriving at the highest speed.<BR>&nbsp;&nbsp;2 The width of increase and decrease at acceleration in male athletes was found to be higher than in female athletes, and then the training for speed maintenance neared by uniform velocity was found to be needed.<BR>&nbsp;&nbsp;3. The acceleration at 60-70M in both male and female groups was found to decrease because of the lack of speed endurance, and then the decrease phenomenon of acceleration was found to bring about loss of entire records, and then also the training of speed maintenance was found to be needed from the highest speed block to final line.
