This study examined the level of preseason conditioning and health maintenance for high school football players in Massachusetts. In July 1988, data were obtained through a survey of high school football coaches regarding players' conditioning programs and injury rates. A total of 286 surveys were distributed to public, private, and parochial schools that have interscholastic football programs. Of these, 182 correctly completed surveys were collected for a 64% return rate. Although many high schools offer a strength training program (88%), very few of the programs have high participation levels. Only two out of five programs had more than 60% player participation. Most high schools used free weights, and many included the use of machines for their conditioning programs. Although one purpose of preseason conditioning is injury prevention, many respondents reported preseason conditioning-related injuries-47% of which involved the low back area. While static stretching techniques were typically used, over 90% of the responding coaches said the stretched position was held no longer than 10 to 20 seconds. Based upon survey results, 10 guidelines were recommended for safe, effective, and efficient strength training. These include recommendations for mandatory preseason conditioning under the direct supervision of trained strength coaches, with careful attention to proper lifting technique and progression.
