Abstract: 

The purpose of this study was to examine the influence of three bouts of 90 minutes high intensity intermittent exercise (specific for soccer) in a week along with carbohydrate supplementation on variations of specific biochemical markers of myocardial muscle ( cTnI, CK-MB ) in soccer players. 12 elite soccer players were selected and divided in three groups of carbohydrate, placebo and control, respectively. They were studied in 12 day time course. For evaluation of the biochemical responses blood samples were taken in 6 phases (3 phases in resting state and 3 phases immediately after exercise) and were analyzed in laboratory with Chemiluminescence's method. Results show that three bouts of 90 minutes high intensity intermittent exercise along with carbohydrate supplementation not induce significant difference in cTnI indices in resting or post exercise. However, there was significant difference in CK-MB values after second session (p=0.038) and third session (p=0.025) than values at first day. Comparison of three groups in different phases show that there were significant difference between carbohydrate and placebo after first session (p=0.009) and second session (p=0.042). It is concluded that since there is not consistent results even after ultramarathon events, it not appear exercises with lesser duration and intensity like soccer even with three sessions in a week be effective on the markers. When overall intensity of exercise is moderate it appear that carbohydrate supplementation have less effective on alteration of biochemical markers of myocardial muscle.
