Brief Summary

Caffeine supplementation has been recognized such as an useful strategy for improving performance in intermittent sports, however caffeine ingestion in futsal has been barely studied. In this randomized placebo-controlled study, we investigated the effects of acute caffeine supplementation in improving neuromuscular performance and physical match activity in futsal players.
