  • Values are mean±SD.

  • One-way repeated measure ANOVA shows significant difference at the level of p<0.05 (#p<0.05).

  • Results of t test *p<0.05, **p<0.01, ***p<0.001 (when compared between the control and experimental groups on a specific visit).

  • ANOVA, analysis of variance; CG, control group (n=40); EG, experimental group (n=37); HIE, high-intensity efforts; HC, hip circumference; RIF, Ramadam intermittent fasting; VJT, vertical jump score; VO2max, maximum oxygen uptake; WC, waist circumference; W-H ratio, waist to hip ratio.
