Background and Objectives: Exercise snacks are defined as short, intense bouts of physical activity (maximum one minute) performed intermittently throughout the day. The purpose of this study was to investigate the effect of high-intensity exercise snacks, as a supplement to physical education classes, on body fat percentage and body mass index (BMI) in overweight male adolescents.
Methods: In this quasi-experimental study, 28 overweight male adolescents (age range 13-18 years, BMI 28.4 ± 2.65 kg/m²) were matched based on BMI and randomly assigned to either an experimental or a control group. The experimental group performed a six-week exercise snack protocol, three sessions per week, consisting of 3 x 1-minute bouts of jump squats (20 seconds), burpees (20 seconds), and high knees (20 seconds), with 1-4 hours of rest between bouts. Body fat percentage and BMI were measured 48 hours before and after the six-week training period. Data were analyzed using paired t-tests and ANCOVA, with statistical significance set at P < 0.05.
Findings: After six weeks of exercise snack training, both body fat percentage and BMI significantly decreased in the experimental group compared to the control group (P < 0.05).
Conclusion: Based on the findings of this study, exercise snacks, when implemented as a supplement to physical education classes, appear to be effective in reducing body fat percentage and BMI in overweight male adolescents.
