It was the purpose of this study to obtain information regarding the use of mechanical aids in football practice sessions in relationship to football injuries. A questionnaire was sent to aid (377) public high school football coaches in the State of Wisconsin. It was found that two hundred and seventy of the two hundred and seventy-four coaches returning the questionnaire used at least one mechanical aid last football season. In Wisconsin 17,866 boys played football last season. A total of 17,372 boys used mechanical aids last season. There were 3,056 players injured that required a doctor's attention last season. This showed that seventeen point one per cent of the boys playing football were injured requiring a doctor’s attention lost season. In this study the author was not concerned with the type or extent of the injury. Seven popular mechanical aids were used as the criterion in this study to gain information about aids and injury. It was found that coaches use aids anywhere from one day to five days per week. The greater percentage of coaches practice four days a week. The mean number of minutes of all seven aids were found in this study. This showed the mean range of minutes the aids were used in a regular practice session. Two correlation problems were used to determine the relationship of aids and injury. Using the Pearson r both correlation problems showed no relationship between the use of mechanical aids and football injuries. Less than one per cent of the players using mechanical aids were injured on his apparatus last session. Therefore the author concludes that mechanical aids are relatively safe to use. The conclusion drawn by the author in this study was that there is no apparent positive relationship between the use of mechanical aids and football injuries.
