CAFFEINE: IS LESS BETTER FOR ENDURANCE?

A new study has investigated the effects of three different doses of caffeine on muscle strength and muscle endurance in resistance-trained men (https://doi.org/10.1123/ijspp.2019-0433). It concluded that a relatively low dose of 2mg per kilo of body weight was as effective in producing lower-body muscle endurance gains as higher doses of caffeine (4 and 6mgs per kilo). The lower dose also appeared to enhance lower-body strength, whereas the higher doses didn’t.
