Abstract:
Purpose of this study was to examine the recovery process of delayed onset muscle soreness, jump performance, force to contact with the ground and lower limbs movement after intensive jump exercise (IJE), and the relationships between muscle soreness, changes of jump performance and lower limbs movement. Nine males who have experience in special jump exercise participated in this study voluntarily. For the measurement, subjective investigation of the muscle soreness, drop jump performance using a 30 cm high box [jump height, contact time and drop jump index (jump height / contact time)], ground reaction force and movements of lower limbs. This measurement was carried out before IJE (Pre), and at 4 hours (P4), 24 hours (P24) and 72 hours (P72) after IJE. Main results are as follows ; at the time of P24 when intense muscle soreness appeared, significant jump height decreases and contact time increases were shown, and the jump index decreased markedly. This decrease of performance correlated to the change of knee and ankle joint movements during the eccentric phase. At P4, for a subject who felt strong muscle soreness, the decrease of jump height and jump index were considerable. At P72, most subjects recovered to the levels of jump height and contact time to the Pre level. The findings reveal that the jump performances are related to the degree of delayed onset muscle soreness.
