A study was conducted to investigate the age-related development of rebound and counter movement jumping ability. A total of 1137 boys (6 yr: 59, 7 yr: 82, 8 yr: 69, 9 yr: 142, 10 yr: 105, 11 yr: 169, 12 yr: 103, 13 yr: 110, 14 yr: 77, 15 yr: 66, 16 yr: 73, and 17 and 18 yr: 82) conducted counter movement jumping (CMJ) as a non-ballistic movement and five-repeated rebound jumping (5RJ) as a ballistic movement. Jumping ability was assessed using CMJ jumping height and the value obtained by dividing jumping height by the ground contact time in 5RJ (RJ-index). CMJ jumping height and the RJ-index in 5RJ increased in accordance with growth. Development of the RJ-index in 5RJ depended on the increase in jumping height, because ground contact time did not change even though jumping height increased with growth. There was a significant correlation between CMJ jumping height and RJ-index in 5RJ (r=0.765, p<0.001, r<SUP>2</SUP>=0.585). Division of jumping ability types was based on±1SD of the residual. These types were as follows: CMJ ability corresponded to RJ ability (CMJ=RJ: n=810), RJ ability was superior to CMJ ability (Good RJ: n=165) and RJ ability was inferior to CMJ ability (Poor RJ: n=162). The number of Good RJ and Poor RJ types increased between the ages of 9-13 years, which is the onset of the growth spurt. These results suggest that CMJ jumping height and RJ-index in 5RJ increase in accordance with growth, but the processes of age-related development of both types of jumping ability do not necessarily correspond to each other, and developmental differences between individuals tend to increase at the onset of the growth spurt.
