Five football teams from major colleges in the nation were surveyed during practices and games in the 1976 season. Data were collected on three packages of information designed as a computer program for tabulation, analysis, and storage of data. Investigators, with a thorough knowledge of football and trained in the use of the program, obtained the data from a given team during every drill, practice, and game of the season. Injury exposure rate was calculated as a ratio of injuries to minutes of exposure in 14 categories (12 specific drills, practice games, and other activities). Agility drills produced the fewest number of injuries for the amount of exposure time (exposure rate, 47,138; risk ractor, 1) and, therefore, it served as a base from which risk factors for all other categories would be calculated. No injuries were recorded in calisthenics. Practice games had the lowest injury exposure rate (1,009) and the highest risk factor (47). Analysis of data is incomplete at this time. The ultimate intent of the study is to help identify and eliminate harmful factors, establish norms, and provide a service to other schools that may desire exposure rate/risk factor data analyzed at a reasonable cost.
1976赛季期间，对全国主要院校的五支橄榄球队在训练和比赛时的情况进行了调查。收集了三类信息包的数据，这些信息包被设计成一个用于数据制表、分析和存储的计算机程序。调查人员对橄榄球有深入了解且经过该程序使用培训，在赛季的每次训练、练习和比赛中从特定球队获取数据。损伤暴露率计算为14个类别（12种特定训练、练习赛和其他活动）中损伤数与暴露分钟数的比率。敏捷训练在暴露时间量方面产生的损伤数量最少（暴露率为47,138；风险系数为1），因此，它作为计算所有其他类别的风险因素的基准。在健身操训练中未记录到损伤。练习赛的损伤暴露率最低（1,009），风险系数最高（47）。目前数据分析尚不完整。该研究的最终目的是帮助识别和消除有害因素、建立规范，并为可能希望以合理成本分析暴露率/风险系数数据的其他学校提供服务。
