PENGARUH KOMBINASI CIRCUIT TRAINING DAN FARTLEK TRAINING TERHADAP PENINGKATAN VO2MAX PEMAIN FUTSAL U-16 DI USC MALANG

Background: Futsal is a high-intensity sport that requires optimal cardiovascular endurance, as indicated by VO₂Max parameters. However, observations show that U-16 futsal players at Unggul Sport Center (USC) Malang still experience fatigue and decreased performance due to low VO₂Max. Therefore, an appropriate training program is needed, such as a combination of circuit training and fartlek training to improve cardiovascular endurance.
Objective: This study aims to analyze the effect of combining Circuit Training and Fartlek Training on improving VO₂Max in U-16 futsal players at USC Malang.
Research Method: This study employed a quasi-experimental design with pre-test and post-test methods. The subjects were all 10 U-16 futsal players at USC Malang, selected using total sampling technique. The intervention, consisting of a combination of circuit training and fartlek training, was administered over 4 weeks with a frequency of 3 times per week (total 12 sessions).
Results: The results showed a significant increase in VO₂Max values after the combination of circuit training and fartlek training was administered. Based on statistical analysis, a p-value of <0.05 was obtained, indicating a significant difference between VO₂Max values before and after the intervention.
Conclusion: The combination of circuit training and fartlek training was proven to be effective in increasing VO₂Max in U-16 futsal players at USC Malang, and can therefore be recommended to improve cardiovascular endurance in adolescent athletes.
