Therefore, the aim of the present study was to evaluate the effect of acute caffeine ingestion (3 mg/kg body mass). Equipment and methods Thirteen elite adult ice hockey male players participated in this double-blind, randomized, counterbalanced, placebo-controlled crossover trial. A 35-m sprint, an agility test (Weave agility-slalom with puck), and a reaction test were performed twice in two separate days. On both occasions players ingested 330 ml of water with lemon isotonic drink (86 kcal/19 g of carbohydrates). On one of the days the drink included 3 mg/kg body mass of anhydrous caffeine. The randomization was performed by a researcher who was not involved in the register of main outcomes. Results No differences were found between the placebo and the caffeine condition for the 35-m sprint (4.223 vs. 4.188 s respectively, P = 0.516), Weave agility test (22.492 vs. 22.341 s respectively, P = 0.534) and reaction test (4.869 vs. 4.837 s respectively, P = 0.570). When analyzing individual results, three players showed improvements in the 35-m sprint while two showed decreases in performance after ingesting caffeine. Caffeine consumption did not improve athletic performance in ice hockey players. 000130029 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000130029 590__ $$a0.8$$b2023 000130029 592__ $$a0.3$$b2023 000130029 591__ $$aSPORT SCIENCES$$b101 / 127 = 0.795$$c2023$$dQ4$$eT3 000130029 593__ $$aOrthopedics and Sports Medicine$$c2023$$dQ3 000130029 593__ $$aSports Science$$c2023$$dQ4 000130029 594__ $$a1.5$$b2023 000130029 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000130029 700__ $$aPantoja, Pablo 000130029 700__ $$0(orcid)0000-0003-0330-5558$$aMoradell-Fernández, Ana$$uUniversidad de Zaragoza 000130029 700__ $$0(orcid)0000-0001-8500-1667$$aMatute-Llorente, Ángel$$uUniversidad de Zaragoza 000130029 700__ $$0(orcid)0000-0002-0520-1640$$aGómez-Bruton, Alejandro$$uUniversidad de Zaragoza 000130029 7102_ $$12008$$2640$$aUniversidad de Zaragoza$$bDpto.
