[Purpose] The time-course effects of individual (ID) and active individual (AID) muscle stretching exercises on jump performance were examined. [Participants and Methods] The jump performance levels (jump heights) of 20 healthy males were measured before, immediately after, and at 5 and 10 minutes after ID/AID stretching and compared between the 2 stretching exercises and among different points. [Results] Both stretching exercises significantly reduced jump heights immediately, but there were no significant differences between them or at 5 or 10 minutes after them. [Conclusion] Both ID and AID stretching exercises reduced jump heights as an immediate effect, suggesting their effectiveness for muscle relaxation as a purpose of static stretching.
