Oxidative Stress on High Intensity Interval Training (HIIT) and Moderate Intensity Continuous Training (MICT)

This study objective was compared the tissue damage caused by physical stress from two types of training in the form of High Intensity Interval Training (HIIT) and Moderate Intensity Continuous Training (MICT) to the levels of malondialdehyde (MDA). Experimental research was used post-test Only Control Design in ten students SMA Pradita Dirgantara Boyolali were divided into 2 groups randomly, group I: HIIT (High Intensity Interval Training), in the form of run 4 times 30 seconds, the intensity of 80–95% MHR, with Work: Recovery ratio = 1:1. While group II: MICT (Moderate Intensity Continuous Training), in the form of continuous running moderate intensity 60–75% MHR for 40–60 minutes. Physical training was carried out for 6 weeks with a frequency of 3 times a week. Immediately after training, all respondents were taken blood samples from the cubital ante vein to be tested for MDA (Malondialdehyde) levels by the ELISA method. Research was shown that HIIT (High Intensity Interval Training) and MICT (Moderate Intensity Continuous Training) trainings have an effects on MDA (malondialdehyde) levels. However, high intensity training (High Intensity Interval Training) contributed to a greater increase in MDA levels that is 37.47% compared to MICT (Moderate Intensity Continuous Training) training of 17.93% of MDA levels. HIIT (High Intensity Interval Training) training has shown to increase MDA (malondialdehyde) levels compared to MICT (Moderate Intensity Continuous Training).
