The Effect of High Intensity Interval Training and Resistance Training in Altering Body Composition of Obese Postmenopausal Women

Abstract

Background: This study was designed to evaluate the effectiveness of High Intensity Interval Training (HIIT) and
Resistance training (RT) on obese postmenopausal women in altering body composition.
Purpose: To compare the effectiveness of High Intensity Interval Training and Resistance Training in altering
body composition of post-menopausal women
Materials and Methods: Twenty obese postmenopausal women randomly selected from Poongothai hospital
, karur were divided into two groups using concealed envelope method. Group “A” was given HIIT three
times a week and Group “B” was given RT three times a week for four weeks. Body mass index (BMI), Waist

post intervention).Study period:October 2022 to June 2023.
Results: Statistical analysis show that there is a significant change within the group for BMI, WC, and WHR pre
and post intervention with a p<0.0001 for both groups A and B. The mean value of HIIT group was 30.2 using BMI,
92.90 using WC, 0.92 using WHR, whereas the mean values of RT was 30.4 using BMI, 93.0 using WC, 0.94 using
WHR As a result, the findings are not statistically as the differences were small.
Conclusion: According to the findings, obese postmenopausal women who took part in the HIIT Group shows
considerable reduction in body composition than RT Group.
