Placebo komparator: Placebo
|
In a double-blind randomized design, participants have taken placebo supplementation in one of the three experimental sessions
|
|
Eksperimentel: Melatonin
|
Our protocol was composed of three experimental sessions.
During each testing session, participants were requested to attend the laboratory at 20:00h where they ingested a standardized light meal.
Melatonin (5 mg or 8 mg) or placebo were ingested in capsule in the evening at 21:00h in a double-blind randomized design
