THE EFFECT OF HIGH INTENSITY INTERVAL TRAINING AND BODY MASS INDEX EXERCISE ON REDUCING BODY FAT FOLD LEVELS

Abstract

The aim of this research is to analyze 1). The effect of HIIT training with a 2:1 ratio on reducing body fat folds, 2). The effect of HIIT training with a ratio of 1:3 on reducing body fat folds, 3). The difference between HIIT training ratios of 2:1 and 1:3 in reducing body fat folds, 4). Differences in decrease in body fat folds between overweight and obese BMI. This research uses a quasi-experimental method, a 2 x 2 factorial research design. The test instrument in this research is 1). Body fat thickness test, 2). Body Mass Index (BMI). Data analysis using Two Way Anova. The research results show: 1). HIIT training with a ratio of 2:1 to a decrease in body fat folds obtained a significance value of 0.01 < 0.005, 2). HIIT training with a ratio of 1:3 to a decrease in body fat folds obtained a significance value of 0.04 < 0.005, 3). HIIT training with a ratio of 2:1 and 1:3 to reduce body fat folds obtained a significance value of 0.02 < 0.005, 4). BMI overweight and obesity on decreasing body fat folds obtained a significance value of 0.00 <0.005.
