Effects of high and low intensity exercise training on body fat in young individuals- Comparative study

Abstract

The purpose of the study is to compare between the high intensity interval training (HIIT) and low intensity steady state (LISS) training for reduction of body fat % in young individuals. Since there are a lot of complications of increased fat in the body, it is necessary to find a protocol for fitness. A sample size of 42 was taken and 2 groups were made of 21 each using chit method. Subjects in LISS underwent a 40mins low intensity workout at RPE 11-12 for 5 times a week including aerobics, jog, and brisk walk. At the same time HIIT subjects had to undergo a protocol of 20mins at RPE 17-18 including 4 cycles of 1min work and 1min rest (step up and down, burpees, push-ups, butt kicks, sumo squats) 3 times a week. Data was recorded post the protocol of 5 weeks. An intraclass analysis showed statistically significant difference in pre and post values of both the groups (p values>0.001), whereas the interclass comparison between both the groups showed significant difference with HIIT having a significantly better result. Thus it was concluded that both the groups helped in fat reduction but HIIT had better and efficient results for fat reduction in young individuals. Also it is time efficient.
