Abstract
This study aimed to examine the relationships among reactive agility, running ability, and turn-around ability in 39 pre-school children. Measurement items were 4- sensor agility for reactive agility, 10-m run for running ability, and pro-agility run for turn-around ability. Significant correlations were found between all items. In particular, the higher the 4-sensor agility is, the faster the 10-m run and pro- agility are. Furthermore, pro-agility had a greater effect on 4-sensor agility than on 10-m run. It was also suggested that it is necessary to increase turn-around ability rather than straight running speed, in order to improve reactive agility.
