The Effects of Repetitive Running on Middle-Distance Runners’ Muscle Damage Level

The aim of this study was to examine the effect of repetitive running on middle distance athletes’ muscle damage. There were 24 female middle-distance athletes who have attended training regularly voluntarily participated in this study. Participants were randomly divided two groups which were experimental (n=12) and control (n=12) groups. Experimental group participants’ mean age, height and weight were (20.90±1.05 year, 160.67±3.20 cm, 57.20±3.07kg, respectively). Control group participants’ mean age, height and weight were (21.13±.64 year, 164.88±4.52cm, 58.13±3.48kg, respectively). Participants’ CK, LDH, Urea, Uric Acid, Creatine, HDL, LDL, Triglyceride, Total Cholesterol, Glucose, ALT and AST values were collected before and after 8 weeks repetitive running training. Data were analyzed with SPSS 24.0 package programme. As a result, it showed that LDH¸ uric acid and creatinine values increased significantly in both groups post-test values. There was no statistically significant difference in pre-post test, CK, Urea, ALT, AST, Glucose, HDL, LDL, Triglyceride and Total Cholesterol values Repetitive running training positively increased LDH levels, while positively decreasing creatine and uric acid levels. As a conclusion, 8 weeks repetitive running training positively affected middle distance athletes’ LDH, creatine and urea levels. Applied training program did not affect other values which are used for determining muscle damage.
