BACKGROUND/OBJECTIVE: The purpose of this study was to examine muscle damage and EMG responses during recovery period following exhaustive concentric and eccentric contractions. METHODS: Fifteen football players participated in this study. In order to evaluate the recovery period after the muscle damage exercise protocol, the expected damage was provoked by concentric and eccentric contractions. The EMG data obtained from Rectus Femoris muscle and levels of CK, LDH, and Myoglobin analysed from plasma were recorded before, immediately after and post 24th, 48th, 72nd, 168th hours of the exercise. RESULTS: Save a significant change in the maximum EMG value of Rectus Femoris muscle, no difference was found among other variables (p > 0.05). While there was no difference (p > 0.05) between the base values (PER) accepted as reference of CK, LDH, Myoglobin and levels at other hours after exercise, there was also no difference (p > 0.05) among values of CK, LDH, Myoglobin between eccentric and concentric contractions. CONCLUSIONS: As a result, various EMG measures and muscle damage responses were recorded during the recovery period after intensive resistance exercises. However the responses during recovery period did not differ by the contraction type.
