This answer focuses on benefits, uncertainty, and practical interpretation. - Evidence regarding the acute effects of caffeine (CAF), L-theanine (TEA), and their combination remains inconsistent, particularly with respect to their combined influence on physical and cognitive performance in athletic populations. [Tuncer SY (2026); evidence level 2] - Results Condition effects were found for leg strength ( p = 0.004, ηp 2 = 0.24) and back strength ( p = 0.008, ηp 2 = 0.19). [Tuncer SY (2026); evidence level 2] - Additionally, no significant difference was found between the conditions in aerobic endurance, maximum isometric handgrip strength, and hand-eye coordination results. [Tuncer SY (2026); evidence level 2] - Introduction Modern athletic performance is driven not only by physical capacity but also by rapid decision-making, attentional control, and visuomotor coordination. [Tuncer SY (2026); evidence level 2] - Sleep is a complex biological process whose evolutionary purpose has remained equivocal for quite some time.More recently, however, compelling evidence has emerged, leading to recognition of the numerous metabolic and physiological functions sleep contributes to and actively supports. [Conti Federica (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
