This study aimed at clarifying the present status and problems of studies on sports injury surveillance studies in Japanese schools. We performed a literature search using databases (CiNii Articles and Google Scholar) and extracted 69 papers involving studies that investigated sports trauma and overuse injuries in schools for the period from 1980 to 2016. Most of extracted studies targeted contact sports and university students. Those reporting only females were limited. In addition, the injury definition and the methods for classifying the body part are varied. There were also aspects of examination and integration difficulties. We found that the problems such as bias in the types and ages of the study subjects and the inconsistencies in the study methods on trauma and overuse injuries.
In Japan, school sports club activities and safety measures are important themes in school sports. The purpose of this study is to present as much objective data as possible regarding how athletic trainers are placed and intervene in athletic club activities in junior high and high schools in Japan and to clarify the current situation. In addition, while analyzing the problems and issues related to the interventions, we tried to identify commonalities and find solutions by assessing the current situation in the United States, where trainer intervention in schools seems to be more substantial than in Japan.
The participation of athletic trainers in high school athletic club activities in Japan was about 20 to 30%, but no objective data regarding junior high school were found. Athletic trainer support for athletic club activities was also desired by instructors and is clearly needed, but more data are needed to prove its involvement. Furthermore, academic discussions are also needed. The search for athletic trainers and the achievement of their placement in high schools, which has been undertaken since the early 1990s in the United States, will be an effective landmark for achieving the beneficial involvement of athletic trainers in Japanese schools.
本研究は，男子大学生ラグビー選手を対象に，肉離れの発生率，重症度，外傷負担，発生要因について分析することを目的とした．男子大学生ラグビー選手113名を対象に，2017年から2018年の2年間に発生した肉離れを記録した．肉離れの発生率は，練習時（0.66/1000 player hours）よりも試合時（13.38/1000 player hours）で有意に高かった．重症度は試合時と練習時で差はなかったが，外傷負担は試合時が282.5 （日/1000 player hours）で練習時の約15倍であった．肉離れの38.5％はランニングで発生したが，次いでラックが26.9％でコンタクトプレーでも発生していた．また，肉離れの既往歴を有する選手は発生リスクが4.5倍であった．若年層からの肉離れの予防と再発予防は，チームの競技時間損失の軽減に貢献すると考えられた．
