Abstract

Training with high intensity and high training volume impacts muscle damage and increased creatine kinase levels. Muscle damage occurs due to mechanical and metabolic stress within the muscle activated during the exercise stimulus. Measurement of serum Creatine Kinase (CK) activity can be used to examine muscle damage indirectly.
The author carried out data collection analysis of creatine kinase (CK) enzyme levels in blood samples and body composition measurement tests using the Bioelectrical Impedance Analysis (BIA) tool. Sampling was carried out using a purposive sampling technique. Out of 101 DKI Jakarta athletes in the sports of judo, kickboxing, muay thai, diving, table tennis, swimming, rock climbing and taekwondo, 81 athletes met the criteria. The data were analyzed using the Spearman^s Correlation test. The results of the study showed that there was a significant relationship (p=0.001) and a moderate positive correlation (r=0.543) between creatine levels and muscle mass. This research also shows a significant (p=0.001) and positive (r=0.566) relationship between creatine levels and protein mass.
This study shows that athletes with high muscle mass and protein mass produce high levels of creatine kinase but with levels that are normal for the athlete category. Further research needs to be carried out to examine the long-term effects of training carried out by athletes.
