The aim of this study was to examine the effect of a ten-week highintensity 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
