The impact of high-intensity interval training on VO2max of futsal student-athletes

Introduction: The level of participation of student-athletes in futsal continues to increase significantly. However, this increase is not accompanied by a variety of training programs. Objective: This study aims to analyze the impact of high-intensity interval training on the maximal oxygen uptake of student-athletes in futsal. Methodology: A descriptive research method with a one group pretest and posttest design was used to achieve the research objectives. A total of 20 male student-athletes were involved as samples. The sampling technique used was total sampling. high-intensity interval training was carried out for six weeks. Each week consisted of three meetings. The maximal oxygen uptake level of student-athletes was measured using an instrument in the form of a Bleep Test. Paired sample t-test assisted by SPSS was used to determine the difference in maximal oxygen uptake before and after the implementation of high-intensity interval training. Results: The results of the analysis showed that there was a significant increase in the mean, median, standard deviation, minimum value, and maximum value. The results of the paired sample t-test showed that there was a significant effect of maximal oxygen uptake before and after the implementation of high-intensity interval training (0.000 <0.05). Discussion: This research highlights the undeniable impact of a six-week high-intensity interval training program in unlocking substantial increases in athletes' maximal oxygen uptake. Conclusion: High-intensity interval training applied for six weeks can increase the maximal oxygen uptake of student-athletes in futsal. This study can be the basis for further research by implementing experiments involving a control group.
