Abstract
The null hypothesis of no effect of melatonin on subjective sleep quality and physical performance could not be rejected (P > 0.30).
- Five milligrams of melatonin were ingested by twelve physically-active subjects before sleep in a double-blind experiment.
- Subjective sleep quality, intra-aural temperature, grip strength, and time to complete a 4 km cycling test were measured the following morning.
- The mean differences in grip strength and cycling performance between melatonin and placebo treatments were less than 1%.
- Confidence intervals for grip strength and cycling performance indicated minimal variability, ranging from -3.1 to 2.8 kg and -3.0 to 4.5 seconds, respectively.
- These findings suggest that melatonin may have little to no impact on physical performance or sleep quality in fit individuals.
