Note that this question is related to Excessive caffeine consumption effect on heart/body. The question and answers however only cover long term usage effects, I want to know about the short term effects.
Which effects does consumption of caffeine during workout have?
I usually drink one or two 0.7l bottles of water before, during and after workout. I drink about one or two cans of tea daily, and was wondering if it has a detrimental effect when I keep drinking tea instead of water while working out.
I also noticed that some pulverized energy drinks contain some amount of caffeine and was wondering what the effects of caffeine consumption are on both strength and cardio exercises.
As I regularly drink coffee, tea or mate I am somewhat used to caffeine. Would there be different effects if I'd increase the dose or if someone who isn't used to caffeine would start consuming during exercise?
