Does Caffeine enhance Performance?

Does Caffeine Enhance Performance?
Several research studies showed improvement in endurance performance followed by caffeine intake. Caffeine increases endurance and speed, but not maximal VO2max and related parameters.

How much?
A minimal dose of 5 mg/kg of body weight (BW) is necessary to induce performance enhancement. However, higher doses of 9 or 13 mg/kg of BW did not show a greater enhancement than the dose of 5mg/kg of BW.
So, a person weighing 60 kg needs to intake 300 mg of caffeine 1 hour before the event to have improvements in his/her performance. Considering that 1 cup of brewed coffee contains 115 mg of caffeine, one pill of caffeine supplement contains 84 mg of caffeine and 1 “espresso” contains 80 mg of caffeine, a 60 kg person would need to drink 3 cups of brewed coffee, or 4 espresso shots OR take 4 pills of supplements or any combination of these drinks (example: 2 espresso shots normally included in 1 largo Latte at Amante + 2 pills of supplements).

There is no advantage to ingesting higher doses of caffeine than outlined above for performance. In fact, ingesting large amounts of caffeine can have deleterious health effects.
