<![CDATA[Background: Physical fatigue can diminish the motor performance and tactical sharpness of futsal athletes. Pre-workout liquid nutrition strategies are required to rapidly optimize exogenous energy availability. Objective: To compare the effectiveness of Ambon banana milkshake and mango milkshake against a commercial energy gel in reducing the anaerobic fatigue index of futsal athletes.Methods: A true experimental design involved 30 male futsal athletes (aged 15–20 years) in Tasikmalaya City, selected via purposive sampling. Fatigue was measured at the end of each week using the Running-based Anaerobic Sprint Test (RAST). Subjects consumed 300 ml of milkshake (or 1 sachet of gel) 30 minutes prior to the physical test. Interventions were administered sequentially: baseline (Week 1), Ambon banana milkshake (Week 2), mango milkshake (Week 3), and energy gel (Week 4). Data analysis was performed using the Paired Sample T-Test.Result: All three interventions significantly reduced the athletes' fatigue index (p<0,05). The proportion of athletes categorized with "good" endurance surged from 10% (baseline) to 60% post-energy gel intervention, closely followed by the Ambon banana milkshake at 56.67%, and the mango milkshake at 33.33%. Conclusion: The commercial energy gel provided the highest fatigue reduction effect. However, the Ambon banana milkshake, as a local functional food, proved to have a competitive physical recovery effectiveness that closely matched the manufactured product. This product is recommended as a practical and economical natural nutritional alternative for futsal athletes]]>
