Group exercise instructors are at particular risk for performance-related injuries because many teach multiple classes each day where they repetitively demonstrate exercise moves. To assess performance-related injuries, a paper-pencil survey was mailed to 1000 randomly selected American Council on Exercise certified group exercise instructors. Questionnaire respondents included 386 professionally certified female instructors from 48 states. Most injuries reported (77%) were of the lower extremity (feet, knee, calf, thigh, shin, ankle, hip). Less than one-fourth of the injuries (23%) were of the trunk or upper body (shoulder, arm, back). The three most commonly reported injury sites were the foot (13.1%), knee (12.5%), and back (9.5%). The three most common types of injury reported were general inflammation (20.7%), muscle strain or sprains (19.6%), and stress fractures (16.8%). Two independent variables were significantly associated with rates of injuries: obligatory exercise scores (p = .0028), and reports of a past eating disorder (p = .0007). Group exercise instructors are at particular risk for injury to the lower body. Those instructors with exercise and eating-related disorders are especially prone to activity-related injuries.

This study is an examination of eating behaviors and body image concerns among 587 female collegiate athletes from nine colleges/universities representing 14 different sports. Measures included the Eating Disorders Inventory-2 (EDI-2), the Eating Attitudes Test (EAT-26), and a questionnaire gathering general demographic information, reasons for dieting and/or using other methods of weight control, as well as information about expressed concerns from others regarding the respondents weight. Three sport groups were hypothesized to be at increased risk: athletes whose performance is subjectively scored; athletes who compete in a sport where a low body weight is considered advantageous; and athletes who must wear body conrevealing clothing. Chi-Square and Logistic Regression analyses revealed no association between these sport groups and the presence of a subclinical eating disorder (SED). Additional analyses determined no statistical association between student-athletes competing at the National Collegiate Athletic Association Division I level (versus Division II or III level) or student-athletes who were scholarship recipients (versus non-scholarship recipients) and the presence of SED. Student-athletes who have heard expressed concerns from others regarding their body weight were significantly more likely to report the presence of SED (p < .0001). Therefore, special care should be taken with all student-athletes when discussing body weight.
