A recent study found that maximal anaerobic power tests and maximal strength tests are not affected by combined caffeine/ephedra intake as well as intake of caffeine by itself.


 


The results showed no differences in body weight, total energy consumption, muscle strength and peak anaerobic power; however, a placebo test showed that participants undergoing the caffeine and ephedra trial reported a perception of increased exercise performance and alertness.


 


The study was conducted in response to the International Olympic Committee lifting its ban on caffeine and allowing more lenience in ephedra levels in athletes. Doses were based on those regarded as therapeutic.
