Abstract :

Introduction: This study aimed to evaluate the effects of a high-intensity interval training program on dribbling skills, body mass index (BMI), aerobic and anaerobic capacity, fatigue index, and intermittent endurance in futsal players aged 8 to 14.

Material & Methods: The research was semi-experimental, with data collected through field measurements. The sample consisted of 30 futsal players, with an average age of 11.73 years, weight of 41.2 kg, and height of 147 cm, who were randomly assigned to either an experimental group (15 players) or a control group (15 players). Measurements included height, weight, aerobic capacity (via the Queen's step test), anaerobic capacity and fatigue index (via the RAST test), and intermittent endurance (via the FIET test). Data analysis was conducted using descriptive statistics, including means and standard deviations, and inferential statistics, including the Shapiro-Wilk test for normality and t-tests for hypothesis testing.

Results: Results showed that high-intensity interval training had no significant impact on BMI. However, significant improvements were found in dribbling performance for the experimental group, and a significant difference between the experimental and control groups was observed in post-test dribbling scores. Significant changes in anaerobic capacity were found within both groups, with a significant difference between groups. Fatigue levels improved significantly within both groups, with a notable difference between groups.

Conclusion: In conclusion, high-intensity interval training is recommended for futsal players.
