The present study investigated the effect of a four-week high-intensity interval training (HIIT) protocol on increasing cardiorespiratory and muscle endurance in futsal extracurricular activities. There were 40 students aged between 15-20 years with both sexes, who were randomly assigned to either an intervention or control group, which received their routine training schedule compared to the HIIT program, respectively. Cardiorespiratory endurance was quantified using a submaximal treadmill test to estimate VO2max, while muscular endurance was assessed with push-up and sit-up tests. Results indicated that the intervention group experienced significant improvements in VO2max (from 45.2 ± 4.1 to 50.3 ± 4.5 mL/kg/min, p < 0.001) and in both push-up (from 15.2 ± 3.4 to 22.5 ± 4.1 repetitions, p < 0.001) and sit-up tests (from 20.1 ± 4.2 to 28.3 ± 5.0 repetitions, p < 0.001). On the other hand, the control group showed no significant differences in any of the parameters evaluated. The findings suggest that a clearly structured HIIT program is effective in improving both cardiorespiratory and muscular endurance in futsal players and that it has immense potential as an effective training modality for attaining maximal athletic performance in sports involving intermittent high-intensity efforts. The results of this study are valuable for futsal as well as other sport categories trainers and coaches who wish to improve physical long-term consequences as well as characteristics of sportsmen. The physiological rationale of HIIT on endurance performance need to be explored through further studies.

Conclusion

The study demonstrates that a four-week interval training program significantly improves cardiorespiratory and muscle endurance among futsal extracurricular athletes.These findings suggest the necessity of incorporating high-intensity training methods within sports preparation programs for optimal performance outcomes in team sports like futsal.By implementing such training protocols, coaches can better prepare participants for competitive competition while fostering a culture of fitness and well-being within sports programs.

Future Research

Penelitian lebih lanjut perlu dilakukan untuk menguji efektivitas program interval intensitas tinggi (HIIT) dalam jangka waktu yang lebih lama, melampaui empat minggu, guna memahami adaptasi berkelanjutan dan peningkatan kinerja pada pemain futsal. Selain itu, studi di masa depan dapat menyelidiki pengaruh HIIT terhadap karakteristik fisiologis spesifik yang relevan dengan futsal, seperti efisiensi gerakan dan kemampuan pengambilan keputusan di bawah tekanan, untuk mengoptimalkan protokol pelatihan. Terakhir, penelitian lebih lanjut harus mengeksplorasi potensi personalisasi program HIIT berdasarkan profil individu pemain, termasuk tingkat kebugaran awal, posisi bermain, dan karakteristik genetik, untuk memaksimalkan manfaat pelatihan dan meminimalkan risiko cedera, sehingga memberikan pendekatan pelatihan yang lebih tepat dan efektif bagi atlet futsal.
