Abstract

The aim of this study was to examine the effect of a ten-week high-intensity interval training (HIIT) program on changes in body composition in women. The study involved 42 female subjects, aged 25 to 32 years, divided into an experimental (n=22) and a control group (n=20). The experimental group participated in a HIIT program three times a week for 10 weeks, while the control group did not have organized physical activity. Body composition parameters were measured using bioelectrical impedance, and statistical data processing included an ANOVA test for repeated measures. The results showed significant improvements in the experimental group in terms of reducing body mass, fat percentage and increasing muscle mass, with statistically significant values (p<0.05) and large effect sizes (eta² > 0.14). It was concluded that HIIT is an effective method for improving body composition in women, and is recommended as an effective form of physical activity in order to improve health and appearance.
