Abstract
The researchers in this study investigated the effect of short-term creatine supplementation on markers of cardiovascular damage after exhaustive exercise in elite karate. For this purpose 7 Karate Ka athletes (mean age 19/4±2/6 yrs, weight of 70/7±7/7 kg, height of 179/7±4 cm) participated in the study, voluntarily. Study method was double-blind. First, subjects were assessed on the treadmill with cardiopulmonary test. Before, after and 30 minutes after; blood samples were taken from the participants. Subjects consumed 20 grams of creatine or placebo per day for 5 days in 4 steps. Then, before and after that they were assessed with cardiopulmonary test. Between the use of creatine or placebo was taken one week apart to clean. The results showed that short-term use of creatine supplementation on markers of heart damage has favorable effects but not markers of vascular injury. Thus, short-term use of creatine supplementation may have a protective role against heart damage.
