Abstract
Background:Sedentary behavior among female university students is on the rise, often associated with weight gain and reduced physical fitness. Tabata training, a high-intensity interval training (HIIT) modality, was examined for its impact on body composition and fitness parameters in normal-weight and overweight female students.
In this study, 52 female students aged 20–25 were randomly divided into four groups: Tabata-normal weight (n=15), Tabata-overweight (n=11), control-normal weight (n=14), and control-overweight (n=12). A Tabata protocol was followed by the training groups for 8 weeks (3 sessions a week). The outcome measures included body weight, BMI, body fat percentage, VO2max, vertical jump height, and agility (4×9 m shuttle run). The data were analyzed using repeated-measure ANOVA and Bonferroni post-hoc tests.
Body weight (P=0.014), BMI (P=0.017), fat percentage (P=0.009), and VO2max (P=0.021) all showed significant main effects, with group-by-time interactions also significant (P<0.05). Only the overweight Tabata group showed statistically significant improvements. Vertical jump (P=0.312) and agility (P=0.281) did not show any significant differences.
Conclusion: In overweight female students, an 8-week Tabata-based HIIT program significantly improved body composition and aerobic capacity, which supports its application in academic settings as an efficient and accessible fitness strategy
