Abstract
SAQ (speed, quickness and agility) is an important fundamental ability in a majority of field and team sports. However, SAQ has not been researched extensively in terms of technical skill of the accelerating body movements in junior athlete. The purpose of this study is to investigate the correlative relationship between sprint ability and initial body movements via a 9 m sprint test. The research was conducted on 51 female junior athletes in a primary school. The mean (SD) age of the athletes was 10.6 ± 1.6 years. The correlation coefficient between sprint ability (9 m sprint time) and length of first step stride, second step contact time, center of gravity movement speed from the starting position in an upright posture to the lowest point, and 0-3 m movement acceleration were −053 (p < 0.01), 0.43 (p < 0.01), −0.67 (p < 0.01) and −0.95 (p < 0.01), respectively. The findings of this study indicate that the body movements to the first step, especially center of gravity movement speed, are related to sprint ability (SAQ performance) in junior athlete.
