Within recent years there has been a wave of research conducted aimed at understanding the performance enhancing benefits of caffeine. Recent research by Chen et al, (2019) looked into how caffeine can reduce muscle soreness in men and women.
The purpose of this study was to see if caffeine attenuates soreness and prevents strength reductions following exercise induced muscle damage. The test was also completed to understand if this differed between males and females.
Researchers involved hypothesised that the caffeine intake after a workout during the recovery period would attenuate soreness, and accelerate strength recovery. They also specified that they believed there would be a difference in males and females as to how much the caffeine attenuated pain.
