OBJECTIVES: This study was to investigate the change of inflammatory markers and fatigue substance of muscle damage on different resistance exercise intensities.
METHODS: The subjects were 7 students (age, 21.0 ± 1.56) in physical education department C University in Gyeongnam. The same amount of exercise was applied to each subject by low and high intensity resistance exercise. Inflammatory and muscle damage markers were based on IL-6, CRP, Myoglobin, CK and LDH. The changes of inflammatory and muscle damage markers on different exercise intensities were measured pre and immediately post exercise and during recovery periods. Blood was collected at each time and analyzed.
RESULTS: The IL-6 level was significantly lower (0.526) after 24 hours than before exercise in the high intensity exercise. Regardless of the difference in exercise intensities, the change was significantly higher(p <.001) after exercise than immediately post exercise and recovery periods(3 hours, 24 hours later). CRP was lower at 3 hours post recovery than at pre - exercise, but there was no significant difference between the intensities of resistance and the time of pre and post exercise. Myoglobin was found to be low (3.19ng/ml) at 24 hours post exercise in high intensity exercise, but it was not related different in resistance intensities and was influenced by time (p <.01). CK was not related to exercise intensities. Regardless of the high or low intensities of exercise, there was a significant change after exercise (p <.01). LDH was not related to the difference in exercise intensity. After 24 hours of both intensity resistance exercise, LDH was lower than before exercise, but the time-period change was high(p <.001).
CONCLUSIONS: Inflammatory and muscle damage markers were not related to exercise intensity. Regardless of the intensity of exercise, Without CRP were changed at the time periods.
