BACKGROUND: Functional training, also known as CrossFit, is a unique sport that combines weightlifting, gymnastics, and metabolic conditioning into a single program. There are an estimated 50 functional training centers in Malaysia. PURPOSE: To analyze the injury rates, patterns, and risk factors of functional training/CrossFit. STUDY DESIGN: Descriptive epidemiology study. METHODS: Electronic questionnaires were distributed to 244 participants from 15 centers in the country. Descriptive data regarding the athletes, injury occurrence within the past 6 months, injury details, and risk factors were collected. RESULTS: Of the 244 athletes, 112 (46%) developed at least 1 new injury over the previous 6 months. Injury rates were significantly higher in athletes from nonaffiliate training gyms compared with CrossFit-affiliated gyms, in athletes with previous injuries, and in those who perceived themselves as having more than average fitness. CONCLUSION: Coaches and athletes need to be more aware of risk factors for injury to enable safer and better training strategies.
