“…In 1998, limits were placed on the number of practices and the number of contacts allowed during spring football practices in an attempt to reduce the injury rate, which was twice as high during spring football practices as during fall practices. 5 Data released in 2008 by the Japanese Football Association 16 indicated that approximately 20 000 football players participated on 402 teams, including 11 junior high school teams, 112 high school teams, 218 university teams, and 61 adult club teams. Despite the relatively large number of players, research regarding football injuries in Japan is limited.…”

“…In comparison, research in the United States has examined injury rates based on multiple-year records. 5,7,10,11,13,14 We aimed to examine practice and game injury rates according to season, injury type, body part, severity, and mechanism in a Japanese Division I collegiate football team over 3 consecutive seasons. Injuries were also analyzed according to position of player, school year, and playing experience.…”

Context: Previous research on American football injuries in Japan has focused on incidence proportion in terms of the number of injuries divided by the number of players. This is the first study to examine injury rates over several seasons.Objective Main Outcome Measure(s): A certified athletic trainer kept a daily record of all practice and game injuries. Injury rates were calculated according to season, injury type, body part, severity, and mechanism. Injuries were also analyzed according to position of player, school year, and playing experience.Results: The game injury rate (GIR; 32.7 injuries/1000 athlete-exposures) was higher than the practice injury rate (PIR; 10.9 injuries/1000 athlete-exposures) over the 3 seasons (P , .05). The PIR was higher among Japanese players than the comparable United States collegiate football injury rates (5.8-7.0 injuries/1000 athlete-exposures). Ankle and foot injuries occurred more frequently during games, whereas thigh and gluteal injuries occurred more frequently during practices.Conclusions: Our data show differences between games and practices in terms of injury rates, body parts injured, and positions of players injured. The high PIR in Japan may be due to the increased contact during practices and length of practices compared with the United States. Further research involving multiple teams is recommended to validate the trends noted in this study. The expanded data set could assist in the development of safety regulations and preventive interventions for Japanese football.Key Words: Japanese football, American football, college football, injury rates Key PointsThe practice injury rate for Japanese collegiate football players was higher than in the United States. This may be explained by the increased contact during practice and unregulated practice length in Japan. Ankle and foot injuries occurred more often during games, whereas thigh and gluteal injuries were more frequent during practices.

Injury incidence was identified using the Sports Injury Monitoring System (SIMS), 19 an ongoing injury surveillance system established for the Big Ten Athletic Conference. Enrolled athletes identified in SIMS as experiencing an injury were contacted 3 months after their injuries.…”

Context: Social support has been identified as an important factor in facilitating recovery from injury. However, no previous authors have prospectively assessed the change in social support patterns before and after injury. Objective: To examine the preinjury and postinjury social support patterns among male and female collegiate athletes. Design: Prospective observational study. Setting: A Big Ten Conference university. Patients or Other Participants: A total of 256 National Collegiate Athletic Association Division I male and female collegiate athletes aged 18 or older from 13 sports teams. Main Outcome Measure(s): Injury incidence was identified using the Sports Injury Monitoring System. Social support was measured using the 6-item Social Support Questionnaire. Data on preinjury and postinjury social support patterns were compared. Results: Male athletes reported more sources of social support than female athletes, whereas female athletes had greater satisfaction with the support they received. Athletes' social support patterns changed after they became injured. Injured athletes reported relying more on coaches (P = .003), athletic trainers (P < .0001), and physicians (P = .003) for social support after they became injured. Athletes also reported greater postinjury satisfaction with social support received from friends (P = .019), coaches (P = .001), athletic trainers (P < .0001), and physicians (P = .003). Conclusions: Our findings identify an urgent need to better define the psychosocial needs of injured athletes and also strongly suggest that athletic trainers have a critical role in meeting these needs.

The purpose of this study is to examine the effect of knee bracing on static and dynamic balance (postural stability).Two knee braces were examined: soft type (A, "Short Runner Airmesh") and hard type (B, "TownsendRebel TM5"). For thirteen collegiate American football players, three conditions -no bracing (Group N), attached brace A (Group A), and attached brace B (Group B) -were set. All subjects performed three tests: a) single-leg standing with eyes closed to measure static balance, b) forward single-leg drop jump with eyes open, and c) lateral single-leg drop jump with eyes open to measure their dynamic balance, by using Zebris PDM-S system. We measured two items: 1. total track length (mm) of center of pressure (COP) and 2. confidence ellipse area (mm Consequently, dynamic balance was shown to decrease when a knee brace was worn, and a hard type reduced dynamic balance more than a soft type. We suspected that bilateral uprights contacted the knee joint hindered the joint proprioception, during controlling the balance of the side movement after landing. Moreover, many compression and contact parts against the knee joint due to the hard shell and rigid straps of a hard type caused to reduce the dynamic postural stability.
