Aim. This study aimed at investigating the rest changes of concentration of Creatine Kinase (CK) and Lactate Dehydrogenase (LHD) after aerobic exercise. For this purpose, 12 male athletes were selected.
Methods. The means and the standard deviation of high, weight, age and body mass index (BMI) were measured and recorded as (175.83±6.06), (68.25±10.33), (19.83±1.40) and (22.01±2.63) respectively. The subjects performed 16 sessions running exercises during 8 weeks. In the first four sessions, their heart rate was 140-150 and in the last four sessions 170-180 times per minute was controlled by Pollar watch. About 3 cc blood sample was taken from the subject’s elbow vein before the exercise. In this process, their concentration average of CK and LDH enzymes in the rest mood and also maximum oxygen consumption (V.O2max) were analyzed by t-test formula.
Results. There was significant difference between CK serum (P=0.023), LHD serum (P=0.021) and V.O2max (P=0.0001), which shows the effects of aerobic exercise on increase of anaerobic enzymes concentration.
Conclusion. This seems to be the result of high degree of aerobic training sessions and also the result of muscular damage during the training period and even 24 hours after the stopping exercise and recovery.
