Background: Indonesia's futsal level stands at 37th in the world. Understanding the demands during the match is very important for improving performance. Futsal is a sport played at high intensity, and the tight schedule of matches, it means that players only have a short rest period. Good aerobic demands are useful for accelerating recovery between high-intensity efforts or even after fatigue. Indonesia is very rich in natural ingredients, including turmeric and black pepper, which are commonly used as ergogenic aids in sports. Turmeric can accelerate the recovery process due to its antioxidant and anti-inflammatory properties, while black pepper has been shown to increase the absorption of curcumin in the body. Aim: Measure and analyse the effectiveness of a combination supplement of turmeric (Curcuma longa L.) and black pepper (Piper nigrum) extracts on changes in biochemical parameters of muscle damage as a recovery process and on the physical performance of futsal players. Methods: A randomized, placebo-controlled study was used. The subject in this study was 32 people, divided into two groups randomly. A total of 16 participants were in the experimental group and 16 participants in the placebo group. The experimental group consumed combination supplement extracts, while the placebo group microcrystalline cellulose. The experimental group consumed extract of turmeric containing 100 mg curcumin and black pepper containing 5 mg piperine, at a dose of 2x/day taken during the day and night. Players used a polar heart rate (HR) monitor during the match, and analyses were conducted on two consecutive days of the match to observe changes in muscle damage with creatine kinase (CK), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) as indicators. Furthermore, physical performance was assessed with countermovement jumps and sprint. Data were collected 6 times, 7 days before the match, just before the match, 24 hours after the first match, 24 hours after the second match, 48 hours after the second match, and 72 hours after the second day of the match. Statistical analyses used were one-way anova, with post hoc Tukey for comparison of time intervals, and t-test for comparison between experimental and placebo groups. Results: The results showed significant differences in CK, as well as AST and ALT values between the test and placebo groups at 24 hours after the second match. The placebo group had a significantly (p<0.05) higher CK value 342 ± 116 U/L compared to the test group 216 ± 46 U/L at 72 hours after the second match. However, the CK value of the placebo group was still high, while the experimental group had returned to the baseline value. Comparison of the placebo group and the experimental group, in CMJ, at 24, 48, and 72 hours after the second match were significantly (p<0.05) different (47.94 ± 4.43 vs 51.38 ± 4.99; 47.50 ± 4.17 vs 52.25 ± 5.85; and 48.25 ± 4.10 vs 53.50 ± 3.96 cm). Furthermore, sprint time at 24, 48, and 72 hours after the second match game in placebo vs experimental groups were significantly (p<0.05) different (3.23 ± 0.20 vs 3.12 ± 0.14; 3.30 ± 0.20 vs 3.16 ± 0.18; and 3.25 ± 0.18 vs 3.15 ± 0.06 seconds). Conclusion: The combination of supplementation of turmeric and black pepper extracts contributes to improved recovery and maintenance of performance in futsal players with tight competition schedules. Thus, fatigue can be avoided, and good performance can be maintained.
