The purpose of this study was to investigate characteristics of past injuries of female university soccer players in comparison with injuries in male university soccer players.
We investigated past injuries of female players (n=32) and male players (n=24) . A past injury was defined as any injury sustained during soccer that required admission to a team doctor, medical attention or absence from practices or games for more than seven days.
The most frequent injury was Joint Injuries in both female and male players. High occurrence of overuse injuries of lower leg was most apparent in the female players. The 32 female players had experienced 144 injuries, or 4.5 injuries per player, and the 24 male players had suffered 85 injuries, or 3.5 injuries per player. The numbers of injuries per player of female players were 1.3 times higher than the male players. Also, the incidence of injury was 0.64 (injury/player/year) in female players, and 0.27 (injury/player/year) in male players. The incidence of injury of female players was significantly larger than that of male players.
We conclude that the prevention and care of overuse injuries in lower leg is very important for female succor players.

Introduction: We evaluated a trainer for improving knot-tying skills using gummy candies (KTG; knot-tying trainer using gummy). To reveal its efficacy, the KTG was compared with a standard knot-tying board by evaluating construct and concurrent validities.　Method: The completion times for knot-tying with the both the trainers were recorded for 18 novices and 18 experts in our university hospital. The evaluation formula was published previously and comprised four items (accuracy, gap, slippage, and breakage) to calculate the total score.　Results: With the standard knot-tying board, the average score was 27.1±22.6 points in the novice group and 37.3±18.7 points in the expert group. There was no statistically significant difference between the groups. With the KTG, the average score was 12.3±20.6 points in the novice group and 36.7±18.3 points in the expert group, with a statistically significant difference (p<0.001).　Discussion: Using the KTG for knot-tying training, it may be possible to acquire knot-tying skills with proficiency-based training, which could improve knot-tying technique.
