Reduction of LDL Cholesterol through MICT and HIIT in Rats

摘要

The reduction of obesity is possible through the use of exercise. It can also be used as a treatment in improving health status. Obese people have higher levels of Low-density lipoprotein/LDL cholesterol, which has the probability of leading to risk of degenerative diseases such as hypertension, stroke and coronary heart disease. Exercising with Moderate Intensity Continuous Training (MICT) and High-Intensity Interval Training (HIIT) methods can lower LDL levels. The exercise process was done for 6 weeks (4 times/week). The subjects were 21 male rats, which were equally divided into 3 groups (control, MICT, and HIIT). The MICT exercise was done at 50-60% of total capacity while HIIT was done at 100% of total capacity. Data collection of LDL levels was done through the use of ABX Pentra LDL Direct CP. Data analysis technique used were ANOVA test and Tukey HSD advanced test (Sig. 0,05). A significant difference between control and MICT group was found, therefore, MICT influences LDL levels. In the Tukey Test results, no significant difference between the control-HIIT group was found. The study showed that MICT was effective and safe in lowering LDL levels in obese subjects. It can be interpreted that regular exercise (MICT) gives positive effects on improvement of health conditions, especially on cholesterol levels of the body.
