Background. Futsal is a high-intensity game that requires both physical endurance and technical precision, particularly passing accuracy. Integrating circuit-based training with small-sided games is considered an effective strategy to enhance these aspects simultaneously.
Objectives. This study aims to evaluate the effect of an 8-week circuit-based futsal training program on endurance capacity (mL/kg) and passing accuracy among novice futsal athletes.
Methods. A total of 60 novice futsal players (aged 12–15 years) participated in this experimental study, divided into two groups: Group A received small-sided games training, while Group B received combined circuit and small-sided games training. The intervention lasted 8 weeks, 3 sessions per week, with each session lasting 90 minutes at moderate-to-high intensity (65–85% HRmax). Endurance was assessed using the multistage fitness test (mL/kg), and passing was evaluated through a standardized passing accuracy test. Data were analyzed with paired and independent sample t-tests, and effect sizes were calculated.
Results. Group A showed significant improvements in endurance (∆ +6.2%, dz = 1.69) and passing accuracy (∆ +28.1%, dz = 1.83). Group B demonstrated larger gains in endurance (∆ +18.3%, dz = 1.24) and passing accuracy (∆ +34.5%, dz = 2.01). Between-group analysis confirmed that the combined program was more effective (p < .001).
Conclusion. An 8-week futsal training program integrating circuit training and small-sided games produced large-to-very-large improvements in both endurance and passing performance. This approach is recommended as a targeted intervention for developing physical capacity and technical skills in young futsal athletes.
