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.

), as well as an increase in knee valgus angle ( Leppanen et al., 2017 ) as risk factors for ACL injury. Reduced lower extremity flexion results in reduced force absorption by the dynamic stabilizers, placing greater loads on the static stabilizers, specifically the ACL ( Alentorn-Geli et al., 2009

Soccer-induced fatigue has been linked with decreased technical performance ( Rampinini et al., 2009 ) and altered lower-extremity neuromuscular control in female soccer players ( De Ste Croix et al., 2015 ).

practical use of these two variables in volleyball. Lastly, this study showed that athletes tended to have a higher impact on jump landings as the season progressed. This metric should be monitored as it may inform an athlete’s risk of lower extremity injury. References Armstrong , R. ( 2005 ). Effects
