Combined Impact of Creatine, Caffeine, and Variable Resistance on Repeated Sprint Ability in Young Soccer Players.
Study Goal
The researchers aimed to determine the summative and isolated effects of caffeine supplementation, alongside other ergogenic aids and pre-activation, on repeated sprint ability in young soccer players.
Results Summary
The abstract does not provide specific results regarding caffeine's effects, but it suggests that caffeine was studied in combination with other factors to assess performance enhancement in repeated sprint ability.

There is evidence that both intra-serial variable resistance (I-sVR), as pre-activation within the post-activation performance enhancement cycle (PAPE), and creatine and caffeine supplementation increase athletic performance in isolation. However, the effect of the three conditioning factors on 30 m repeated sprint ability (RSA) performance in young soccer players is unknown. This study determined the summative and isolation effect of ergogenic aids and pre-activation in half-back squats (HBSs) with I-sVR on performance in an RSA test in young soccer players. Twenty-eight young soccer players were randomly assigned to either EG
