The effects of prolonged exercise on cTnT and inflammatory markers in young-aged adults.
This study aims to investigate exercise-inducing changes in Cardiad Troponin T(cTnT) as cardiac bio-markers, effects on serum lipids and inflammatory markers, and cTnT-influencing factors during one-time prolonged exercise. A sample of experiment consists of eight adult males. For one-time prolonged exercise program, target heart rate was kept with 42% for the first one hour of exercise, 60% after one hour, 80% after two hours. Total cholestrol, which is serum lipid, triglyceride, HDL-cholesterol and LDL-Cholesterol are measured. As inflammatory markers WBC, CRP are measured and the following results are obtained. LDL-C, WBC showed significant increase(p<.05) and TG showed significant decrease(p<.05) in exercising hours. Total-C, CRP showed no significant differences in exercising hours. The concentration of cTnT showed no significant differences in exercising hours but, three adult males showed an increase close to the level of Acute Myocardial Infarction(AMI) cut off, cTnT showed a positive correlation between time(r=.432), WBC(r=.431), and heart rate(r=.431). As a result, this study indicates that one time prolonged exercise can induce an increase in cTnT as cardiac bio-markers among adult males who don't exercise regularly, and it can also result in the risk of sudden death. Such a concentration of cTnT represents a significant correlation with the level of WBC and accordingly, cTnT increases significantly at higher level of WBC.
Key words: prolonged exercise, heart rate, cTnT, CRP, WBC
