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. 

This study investigates the impact of repetitive running on muscle damage in middle-distance runners.
