The purpose of this study was to investigate the relationship between the the physical ability of female collegiate badminton players and their shot skills. The subjects were female collegiate badminton players with similar athletic careers (around 10 years)．First, to clarify the athletic ability of the athletes, a round robin tournament was held to rank the participants (ranking points were given) and the relationship between the results and their shot skills that are frequently used in competitions, was analized. Then next, we investigated the relationship between shot skills and their physical abilities (muscular functional strength, anaerobic and aerobic capacity) which included their abilities to move on the court. The results are as follows: 1. There were positive correlation between ranking points and shot skill points (for clears and smashes)． 2. There were high correlation between ranking points and 6-direction footwork agility test, 30 times repeated shuttle, and total work of isokinetic knee joint extensor muscular strength. 3. There were high correlation between shot skill points especially in smash and mean anaerobic power output, 6-direction footwork agility test, 30 times repeated shuttle, and total work of isokinetic knee joint extensor muscular strength. The above results suggests that improving both the clear and the smash shot skills, improving aerobic capacity on the on-court by doing a 30 times repeated shuttle, improving lower limbs extensor strength and maintaining anaerobic power output may lead to a high level of smash shot skills that can be the key to deciding matches.
