Caffeine improves volleyball serves precision among college male players

Abstract

Objective: The aim of this study was to identify whether caffeine ingestion affects the precision of volleyball serves. Material and Methods: The study´s design was double-blind, crossover, and counterbalanced. Nineteen college volleyball players took part of the study. They performed two adapted volleyball matches on different days, separated by a 72 hours interval. Before the matches, they consumed randomly 6 mg·kg -1 of caffeine or placebo. After each volleyball match, a serving precision test with two sets of ten serves was performed. Results: The evaluation of each serve's mean (placebo or caffeine) as well as the sum of total points according to the serve's order and intervention were not statistically different. However, the caffeine intervention mean scores were significantly
