　The present study was conducted to investigate the strength and power characteristics of the lower limb using the rebound jump (RJ) for collegiate female soccer players, focusing on the relationships between running performance, muscle strength and differences in competition level. The performance variables of 19 collegiate female soccer players in the 20 m sprint, pro agility test, squat, isokinetic knee strength, countermovement jump, and RJ were calculated. The kinetics data (ground reaction force, joint torque, power, joint work) in the RJ were then calculated. The results revealed no relationship between performance variables in the RJ and various parameters related to running performance and muscle strength. However, in the starter group, the 20 m sprint time and pro agility time were significantly faster, the RJ-index was significantly higher, and contact time in the RJ was significantly shorter. In addition, in the starter group, the maximum ground reaction force, ankle joint torque, power, and knee joint torque in the first half of the take-off phase were large. Therefore, it is suggested that female soccer players with a high competition level have excellent strength and power abilities, particularly in terms of ankle joint and knee joint muscle strength and power exertion ability to achieve the jumping height in a short contact time.
