Data were analyzed by repeated measure ANOVA and Bonferroni tests in SPSS26, α = 0.05).<br />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). <br />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.
