A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. ⋯ The athlete returned to competitive activities after 5 months. One year later he lifted 170 kg and won the national championship.
