Sobre os efeitos (benéficos) de alguma cafeína sobre os desportistas. E quanto se deve poder tomar (e de que forma):
Citando:
"[Quantities:] According to Center for Science in the Public Interest, Starbucks espresso (75mg/shot), black tea (30-80mg/250mL), green tea (35-60mg/250mL).
Many runners rely on caffeine-laced gels, blocks, and beans for a mid-run pick me up. Because there are many levels of caffeine in these products, always be careful to check the label of your favorite flavour to see how much it might contain. In general, if a product contains caffeine, it likely offers somewhere between 25-100mg per serving. Athletes who don’t often use caffeine but want to try out a mid-run fuel with some kick would do well to start with a conservative 25mg dose and see how they respond."
