초록
본 연구에서는 선행 연구에서 수집한 자료를 사용하였다. 대학야구 선수의 스포츠상해 실태조사를위해26개대학에소속된757명의선수로부터수집된자료를활용하여상해발생률을 산출하고상황별비교및평균비교분석에적용하였다. 개인훈련, 팀훈련, 경기의수행빈도와 수행시간을 각각 반영하여 노출시간(참가시간)을 계산하였으며 1,000시간 당 상해 발생률을 산출하여제시하였다. 상해발생률로비교한결과, 빈도분석을이용한선행연구의결론과는 다르게경기상황에서의발생률이가장높게나타났다. 추가로경력, 경기력수준, 포지션에따라 발생률에차이가있는지를비교하였으며, 모든집단간평균비교에서유의미한차이가없는것으로 나타났다. 스포츠상해 연구에서 빈도분석은 여전히 중요하며 기초자료를 제공한다는 점에서 의미가크다. 이에더해발생률정보를제공하면연구결과의활용도를높일것으로기대된다. 같은 조건에서산출된발생률을이용하면한연구내에서비교뿐만아니라다른연구의결과와도동일한 선상에서비교할수있는장점이있기때문이다.
Abstract
This study utilized the data set used in a previous study. Data were collected from 757 players from 26 universities to investigate the status of sports injuries in college baseball players. In this study, the data set was used to calculate injury incidence rates and compare incidence rates based on situations, injury types, and injured body parts, respectively. Exposure time (participation time) was generated by considering the frequency and duration of individual training, team training, and games. Then, injury incidence rate per 1,000 hours was calculated and presented. It was found that, the injury incidence rate in games was much higher than other situations. In addition, group differences in the incidence rate variable were compared based on athletic career (less or over 10 years), team performance level (high-, moderate-, and low-groups), and playing positions. No significant differences were found in all comparisons in all conditions. Frequency analysis is still important in sports injury studies in that providing fundamental information and baseline data. If incidence rate is additionally included, besides frequencies and percentages, it is expected to enhance the usability of a study. Once incidence rates are calculated under the same time-unit condition it enables all comparisons not only within a study but also across studies.
