IMPACTS OF HIGH-INTENSITY INTERVAL TRAINING ON BODY COMPOSITION OF FEMALE UNIVERSITY STUDENTS

Abstract

ABSTRACT Introduction: In recent years, high-intensity interval training has become a popular tool to help maintain body composition and reduce fat mass. It is believed that its benefits may extend to female college students. Objective: Analyze the impacts of high-intensity interval training on the body composition of female college students. Methods: Thirty high school girls at a university were selected as volunteers for an 8-week experiment. Divided equally into two groups, the experimental group received high-intensity interval training while the control group followed with routine physical training. Results were collected before and after the experiment for statistical analysis. Results: The waist circumference of the experimental group was reduced from 83.74 ± 4.55 cm to 76.49 ± 4.48 cm; hip circumference was from 101.53 ± 3.01 cm to 95.26 ± 2.99 cm; and body fat from 37.29 ± 2.09 kg to 32.93 ± 1.68 kg. The body composition index's body fat content was reduced from 29.01 ± 1.31% to 28.63 ± 1.29%. In contrast, the indexes of the control group did not change statistically compared to before training. Conclusion: High-intensity interval training can effectively improve the body composition of female college students, considerably impacting body fat reduction.
