Ankle injuries are among the most common injuries in soccer. A contributing factor to ankle injuries is decreased proprioception. It is important to find ways to improve proprioception in order to decrease the incidence of ankle injuries in soccer players. This study examined the effects of plyometric training on ankle proprioception in a specified athletic population. We compared two" groups (N=18) of high school female soccer players; ten players served as our experimental group and eight players served as our control group. The experimental group did plyometric exercises along with their normal training program while the control group did their normal training program without any plyometric exercises. These training programs lasted eight weeks. Pre-season and post-season postural sway measures were taken on the Chattecx Balance System as a means for measuring proprioception. Static and dynamic single leg postural sway measures were recorded. During testing, each participant wore a Japanese lantern forcing her to rely on proprioceptive information to maintain balance. The results showed that plyometric training did not improve postural sway. However, the experimental group had 17.5% fewer injuries during the season as compared to the control group.
