Documentation about the relationship between fatigue and dance injuries is sparse. Dancers often train in settings that do not enforce regulated exposure and periodization, cardiovascular fitness training, or adequate hydration and nutrient repletion. Yet to this author’s knowledge, only two studies examining the effects of fatigue on dance injuries have been published. Kadel et al (AJSM, 1992) demonstrated a relationship between number of hours danced per day and stress fracture rates. Liederbach et al (MPPA, 1994) demonstrated a relationship between fatigue and onset of injury as measured by changes in urinary catecholamines and Profile of Mood States®. In the sports literature, numerous studies have shown that chronic athletic fatigue adversely affects motor control via multiple physiological pathways (Noonan et al, AJSM, 1994; Costill et al, MSSE, 1998; Morgan, BJSM, 1987; Snyder, MSSE, 1998; Gabriel et al, MSSE, 1998; Gatsmann, MSSE, 1998; Lehmann et al, MSSE, 1998; Kannus, SJMSS, 1997; Bennell BJSM, 1996; Houston & Wojtys AJSM 1996; Rowbottom, EJAP, 1995; Hewitt, AJSM, 1999). In the present study, 500 injury report forms of dancers from three different settings (a professional ballet company, a university conservatory, and a hospital-based orthopaedic clinic) were analyzed for injury factors. Data revealed that fatigue factored out as the most common variable associated with injury in all three groups. The injury circumstances associated with the fatigue variable will be described and physiologically based, practical recommendations for clinicians and teachers about how to monitor fatigue in order to avoid onset of fatigue-related injuries in the dance environment will be provided.
