Caffeine Better in the Morning or Afternoon?
Caffeine has long been part of the pre-workout regimen for all gym advocates and professional athletes. Caffeine is well-known as a central nervous system stimulant. Studies have shown that caffeine can help an athlete perform better in a variety of different activities. It has been shown to be a powerful ergogenic aid that is beneficial in athletic performance and training. Caffeine has been shown to increase speed and power output, improve the length an athlete can train, and assist the athlete in resisting fatigue. Caffeine reduces fatigue and increases concentration and alertness, and athletes regularly use it as an ergogenic aid.
Trained athletes seem to benefit from a moderate dose of 5 mg/kg, however, even lower doses of caffeine (1.0–2.0 mg/kg) may improve performance. Some researchers have found significantly improved time trial performance or maximal cycling power from caffeine use. A new study recently found that if you want to get the most out of your caffeine, take it in the morning.
