ABSTRACT

High intensity of physical exercise in long period causes muscle damage. Muscle damage in physical exercise can occur due to muscle stretching followed by sarcomere disruption. Muscle damage can be detected by measuring several indicators or markers. Muscle protein efflux during severe physical activities signed by the increase of LDH (lactate dehydrogenase) and CK (Creatine Kinase). Many studies explained the effect of high intensity physical exercise in long period on muscle damage, but only few studies investigated the effect of high intensity exercise in short period. The purpose of research is to analyze the high intensity short period exercise on blood lactate and creatine kinase serum between elite and non-elite athlete. The post test only group design study was conducted to reach the aims of research. Seventy-five participants involved in this research and they were elite athletes (n=37) and non-elite athletes (n=38). The elite athletes were 24.71 ± 4.753 years old, while the non-elite athletes were 20.19 ± 1.619 years old. All participants perform Running -based Anaerobic Sprint Test (RAST) as a high-intensity short period exercise. The velocity of athletes was calculated for each running track. The blood for lactate level and creatine kinase (CK) measurement was taken as soon as they finished the RAST. The blood lactate level was 6.96 mmol/L (non-elite) and 5.5 mmol/L (elite). The serum level of CK was 241 (non-elite) and 198.8 (elite). Both of elite and non-elite CK level were higher than normal value. There was no difference in blood lactate (p=0.063) and serum level of CK (p=0.241) between elite and non-elite athlete. The conclusion was the blood lactate and CK serum level after high intensity short period increased higher than the normal value. There was not difference between elite and non-elite athletes, suggesting that the elite and non-elite athletes put in the same effort in performing and running the test. The recommendation of this research is that the high intensity short period exercise should be alternatively implemented to avoid muscle damage to athlete.
