The Relationship between Lower Limb Explosive Power and Ability of Sprint and Change of Direction in Male College Soccer Players:Focusing on the Difference between Jumping Types [Received July 18, 2019; Accepted October 30, 2019] The purpose of this study was to investigate the relationship between lower limb explosive power, sprint and change of direction according to jumping type in male college soccer players. This study recruited 97 college soccer players including High level (n=50) and Low level (n=47). Participants who have been selected for the national team were classified as Top level (n=6). All of the participants conducted the following, with their results recorded for analysis: 30m sprint (30mS), Pro-agility test (PA), counter movement jump (CMJ) and rebound jump (RJ). All of the participants were classified into two types: CMJ type (relatively greater in CMJ), RJ type (relatively greater in RJ-index). The relationships between CMJ, RJ, 30mS and PA were analyzed in each type. The results indicated that CMJ showed significant negative correlation between 30mS and PA in CMJ type and RJ type respectively. On the other hand, RJ-index showed a significant negative correlation between 30mS and PA only in CMJ type, but no relationship was found in RJ type. It was also revealed that the number of RJ type was particularly large at the high level, and the CMJ type was large at the low level. Participants at Top level were significantly superior to those at High level in RJ-index and CMJ. On the basis of these findings, this study has shown that the importance of relatively high RJ ability and possible availability of training program according to jumping type.
