Background: This study aimed to investigate the effect of caffeine and carbohydrate co-ingestion on anaerobic performance and muscular strength of female wushu athletes. Methods: 7 female wushu athletes with 22.00 ± 6.11 years of age, 52.96 ± 4.87 kg weight and 161.29 ± 5.28 cm height participated in 1RM leg and bench press and RAST tests on 4 occasions separated by 1-week washout after accidental consumption of caffeine (6 mg/kg in 250 mL water), 8% carbohydrate (21 g in 250 mL water), caffeine+carbohydrate and placebo. Data were analyzed by repeated measure ANOVA and Bonferroni tests in SPSS26, α = 0.05).Results: caffeine alone did not affect variables (P ≥ 0.05). Carbohydrate consumption increased 1RM bench press ⁓7% (P = 0.010) and 1RM leg press ⁓16% (P = 0.033). co-ingestion of carbohydrate and caffeine improved mean power ⁓15% (P = 0.027), 1RM bench press ⁓26% (P = 0.005) and leg press ⁓39% (P = 0.027). Conclusion: it seems, that carbohydrate has more effect on strength than caffeine, but combined with caffeine it may improve mean power besides the muscular strength in female wushu athletes due to effects on the central nervous system and increasing carbohydrate effect.
