EFFECTS OF THE KFIT EXERCISE CLASS ON BODY COMPOSITION IN FEMALE STUDENTS WHO EXERCISE REGULARLY

Abstract

The purpose of this research was to study the effects of KFIT exercise class on body composition in female college students at Rajabhat Maha Sarakham University who exercise regularly and compare them with the group that exercises on their own as usual. The sample group consisted of female students. A specific sample of 16 people was selected, divided into an experimental group of 8 people, and performed 30-minute KFIT exercise classes twice a week. In conjunction with regular self-exercise, a control group of 8 people performed self-exercise. Body composition was assessed before the experiment, including body mass index, fat percentage, fat mass, and skeletal muscle. Total muscle mass and body weight data were collected for 4 weeks, and body composition was assessed after the 4 weeks of the experiment. Data were analyzed by mean and standard deviation. When comparing the means within groups with t-test dependent and t-test independent statistics, the research results found that when comparing within the experimental group, there was a difference between skeletal muscle and total muscle mass. But when comparing body composition between groups, no statistical differences were found. In conclusion, in comparison between the control group and the experimental group, no statistical difference in body composition was found at the 0.05 level, but the experimental group that exercised in the KFIT class found that skeletal muscle and total muscle mass show a statistical difference at the level of 0.05. Therefore, KFIT exercise classes are an option for people who exercise regularly and can still maintain muscle mass.
