|Beneficial effect of caffeine intake on team-sport performance|
Eleven male rugby players ingested either caffeine (6 mg/kg) or placebo 70 min before performing a simulated intense team-sport performance.
After caffeine intake 20-m sprint speed, power generation in a drive and passing accuracy improved by 1, 5 and 10%, respectively. These changes were associated with a 50% increase in mean plasma epinephrine concentration. Thus, caffeine produced marked enhancements of several aspects of intermittent high-intensity team performance.
Recommendations: Soccer players may benefit from ingesting caffeine about 1 h before a game.

Biomarkers of inflammation such as C-reactive protein, which are associated with chronic diseases, are reduced in active individuals relative to sedentary individuals, and the positive effects of exercise may be due to its anti inflammatory effects. Thanks.
