The Claim
Caffeine administration at 3 mg/kg has no effect on oral temperature in adolescent male volleyball players, and its cognitive effects are mediated by neuropharmacological mechanisms independent of thermoregulatory changes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Giving adolescent male volleyball players 3 mg of caffeine per kilogram of body weight does not change their oral temperature, and any cognitive effects from caffeine occur through direct brain mechanisms, not through changes in body heat.
See the scientific wording
Caffeine administration at 3 mg/kg does not alter oral temperature in adolescent male volleyball players, indicating that its cognitive effects are mediated by neuropharmacological mechanisms rather than thermoregulatory changes.
Caffeine enters the brain and blocks signals that make you feel tired, which lets brain chemicals that boost alertness and focus become more active, making you react faster and think more clearly without changing your body temperature.
What the research says
1 studyCaffeine helped young athletes think faster and react better without making them hotter, which means it works by changing brain chemistry, not by warming up their bodies.
