TL;DR
The results showed that performance over 1 mile across the three supplementation conditions did not differ, and caution against melatonin for performance, particularly when used outside its sleep-promoting context.
Abstract
Sports nutrition, which uses ergogenic substances, has emerged as an important tool that favors athletes’ performance. Like caffeine, melatonin has been investigated as a potential ergogenic aid; however, its effects are not yet fully understood. This study aimed to evaluate the effects of acute melatonin and caffeine intake on performance and sleepiness of runners in the 1 mile physical test. A total of 24 healthy, active, and experienced male runners were selected. Participants completed a 1 mile run under three supplementation conditions (placebo, melatonin, and caffeine), each separated by a 1 week washout period. All evaluations were carried out at the same time. Sleepiness was assessed for 5 h after each supplementation. The results showed that performance over 1 mile across the three supplementation conditions did not differ. Melatonin consumption maintained an increase in sleepiness up to 5 h after the test. These findings caution against melatonin for performance, particularly when used outside its sleep-promoting context.
Background: Caffeine is a well-established ergogenic aid that improves endurance performance at acute doses of 3–6 mg/kg. Widespread habitual intake, mainly via coffee, raises the question whether chronic exposure blunts this effect.
Aim: To critically assess whether regular caffeine consumption, particularly habitual...

PURPOSE
Physiological strain, mental exhaustion, and sleep deprivation are key elements that hinder performance during multi-day endurance activities. Ketone monoester supplementation (KE) may enhance post-exercise recovery, preserve cognitive function, and increase both sleep quantity and quality. Therefore, we simula...

Background
Cycling is a highly demanding endurance sport, in which small improvements in performance may significantly influence results. Caffeine is one of the most commonly used ergogenic aids among athletes, due to its potential to enhance physical performance and delay fatigue. Understanding its effects on cycling...

Background. Matcha and coffee are widely consumed sources of caffeine and other bioactive compounds. Caffeine-mediated effects are well established, but the distinct phytochemical profiles of these beverages contribute to different physiological responses. Direct comparisons between matcha and coffee remain limited.

Background: Caffeine’s ergogenic effects on cognitive function are well-established, but the potential confounding influence of withdrawal is less understood. This study examined the effects of caffeine withdrawal and withdrawal reversal on mood and cognitive performance in habitual caffeine consumers. Methods: Twent...
