The effects of Two-Week High Intensity Interval Training on Weight Loss in School Going Obese/Overweight Students

Abstract

BACKGROUND- Children and teenagers are becoming more and more obese all around the world. High Intensity Interval Training (HIIT) allows for short, intense bursts of activity followed by quick recovery periods, which can be repeated many times. This lead them to seek effective, inexpensive approaches that can burn a lot of calories in a short amount of time. To implement a home-based effective weight loss program through HIIT. The main objective of this study is to evaluate the effects of HIIT on weight, pulse rate, oxygen saturation (spO2), waist circumference (WC) and body mass index (BMI). METHOD - Ten different schools were selected, screened for the overweight/obese subjects and they were randomly assigned to supervised group (n=15) and non- supervised group(n=15). All the subjects performed 45 minutes of a HIIT body workout, consisting of random repetitions of 45 seconds of each exercise followed by 5 seconds of passive recovery for two weeks. RESULT – The pre and post-treatment mean values showed a significant result in both the groups (<0.05) on weight (2.18 ± 1.08), WC (5.6 ± 2.73), spO2 (0.07 ± 1.86), pulse rate (10.73 ± 13.2), and BMI (1.01 ± 0.37). CONCLUSION – This study provides the evidence that supervised HIIT is proved effective in reducing weight.
