EXAMINATION OF TIME-COURSE EFFECT OF EXERCISE INDUCED SKELETAL MUSCLE DAMAGE ON THE POWER SPEED AND BALANCE PERFORMANCE

The purpose of this study was to investigate the time-course effects of an exercise that creates muscle damage on muscle strength, power, speed and balance performance of young male subjects. Ten male subjects (age mean 21.1 ± 3.4 years, height 171.2 ± 6.1 cm, body weight 64.1 ± 4.7 kg) voluntarily participated in the study. On the first day of the study, participants’ height and body weight measurements and muscle pain, Creatine Kinase (CK), balance, power and speed test baseline values obtained. On the second day, a training protocol was performed and the muscle pain, balance, power and speed tests, and CK values were measured at 1, 24, 48 and 72 hours after the protocol. SPSS 19 package program was used to analyze the data. The data were evaluated using the ANOVA test for repeated measures. CK and muscle pain values at 1, 24, 48 and 72 hours after exercise protocol were significantly higher than baseline (p<0.05). There was no significant change in balance and power values at any measurement time (p>0.05). The speed values were statistically significantly higher at 24 and 72 hours after exercise compared to the baseline values (p<0.05). As a result; muscle damage exercise protocol, increased CK and muscle pain scores, adversely affected the speed performance but had no effect on balance and power performance of the subject
