IJERPH, Vol. 15, Pages 1378: High Body Mass Index Is Associated with the Extent of Muscle Damage after Eccentric Exercise

International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071378

Authors: Jooyoung Kim Wi-Young So

Purpose: The present study aimed to investigate the effects of body mass index (BMI), which is an obesity index, on the change in the muscle damage index after eccentric exercise. Methods: Forty healthy male university students participated in this study and were classified into normal (BMI 18.5–22.9 kg/m2, n = 20) and high BMI groups (BMI ≥ 25 kg/m2, n = 20). For eccentric exercise, a modified preacher curl machine was used. Participants performed two exercise sets with 25 repetitions in each set. With regard to the muscle damage index, maximum strength, muscle soreness, and the creatine kinase (CK) level were measured. Results: Loss of maximum strength, muscle soreness, and the CK level were higher in the high BMI group than in the normal BMI group (p < 0.05, p < 0.05, and p < 0.01, respectively). Conclusions: In conclusion, BMI is one of the potential factors related to muscle damage after eccentric exercise.
