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.
To date, no previous investigation has studied the effect of acute caffeine ingestion on futsal performance during futsal-specific testing and during a simulated match. Therefore, the aim of this investigation was to establish the effects of acute caffeine intake on futsal-specific tests (e.g. futsal kicking velocity) and match-play running performance in male futsal players.
