Effects of concurrent and mixed-methods training on physical performance in futsal athletes

Introduction. Futsal requires high-intensity performance, involving both aerobic and anaerobic energy systems. Athletes must maintain agility, strength, speed, and endurance throughout matches. Objective. This study aimed to compare the effects of concurrent training and mixed-methods training on agility, maximal strength, speed, repeated sprints, VO₂ max, and power in futsal athletes in Thailand. Methodology. Thirty-six male futsal players were randomly assigned into three groups: concurrent training, mixed-methods training, and control. The training groups trained three times per week for eight weeks. Pre-, mid-, and post-intervention tests were conducted. Variables were measured using standard physical fitness assessments, and statistical analysis was performed using two-way ANOVA and ANCOVA. Results. Both training methods significantly improved multiple performance variables. Concurrent training led to greater improvements in maximal strength, VO₂ max, and power, while mixed-methods training showed superior effects on agility and repeated sprints. The control group showed minimal improvements. Discussion. Findings align with prior research, confirming that concurrent training improves strength and aerobic capacity, while mixed-methods training enhances agility-related abilities. The specificity of training programs influenced the type of physical adaptation achieved. Conclusions. Both concurrent and mixed-methods training are effective for enhancing the physical fitness of futsal athletes in Thailand, and should be selected based on specific performance goals.
