About this study
Official title: Effects of Acute Caffeine Ingestion on Futsal Performance in Sub-elite Players
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.
Read the detailed description
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.
- Being tested
- Caffeine, Placebo
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CaffeineDietary 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.
PlaceboDietary 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.
| Study group | Role | What they receive |
|---|---|---|
| Caffeine supplementation | Experimental | Acute caffeine supplementation Receives: Dietary Supplement: Caffeine |
| Placebo supplementation | Placebo comparator | Acute placebo supplementation Receives: Dietary Supplement: Placebo |

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in futsal match-play demands (m/min) (time frame: 48-hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04852315, which also lists 1 linked publication.
