Acute Caffeine Ingestion on Futsal Performance

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Sub-elite men futsal players

Exclusion criteria

  • Intolerance to caffeine,
  • Suffering from any chronic pathology or an injury in the month prior to the investigation
  • Use of medicines or dietary supplements during the study.

Treatment and study plan

Caffeine

Dietary Supplement

Gelatine capsule with caffeine (3 mg/kg body mass of caffeine) (Bulk Powders, London, United Kingdom). The capsule containing the treatment was ingested with 150 mL of water 60 minutes before the onset of the experiment to allow substance absorption.

Placebo

Dietary Supplement

Gelatine capsule with placebo (Cellulose; Guinama, Valencia, Spain). The capsule containing the treatment was ingested with 150 mL of water 60 minutes before the onset of the experiment to allow substance absorption.

Secondary outcomes

  1. Changes in maximal jump height (cm)
