Purpose: To assess the impact of chronic ankle instability (CAI) on cardiorespiratory fitness and body composition. Methods: Seventeen participants with CAI were matched for sex, age, height, and weight to participants with no history of ankle injury. Body composition was assessed by dual-energy x-ray absorptiometry. For the treadmill test, a 2-minute progressive test was used until volitional fatigue occurred. Results: Body composition was different between the CAI and control groups (P =.0002). The maximal oxygen uptake (VO
2max ) (mL/kg/min) was significantly less in the CAI group (P <.0001). Time to maximal exercise test completion (P =.02) and maximal minute ventilation (VEmax ) (P =.008) were less in the CAI group. Maximum heart rate was not different (P =.96); however, resting heart rate was greater (P =.0001) in the CAI group. Conclusions: CAI may result in reduced physical activity and cardiorespiratory fitness accompanied by significantly greater body fat percentage. The results suggest that these serious negative health outcomes may rapidly develop from the reoccurrence of this musculoskeletal injury.
