Summary
Caffeine is one of the few supplements that have enough scientific evidence to state that can
notably improve performance, as different remarkable organizations in the sports nutrition
context have classified it as an ergogenic aid with strong evidence regarding its efficacy
and that is apparently safe. The beneficial effect of this substance on physical and
cognitive performance has been identified in aerobic and anaerobic efforts, including aerobic
and muscular endurance, power, or strength.
However, it seems that the benefits of caffeine are usually measured only by its effect on
performance, while a comprehensive analysis of its impact on other aspects of the movement
technique of the exercise is not considered. Therefore, although caffeine generates better
performance, a null or negative effect may occur on technique execution. As such, some
consequences might arise (e.g., an increase in injury risk or a decrease in energy
efficiency).
The objective of this randomized controlled trial is to assess the influence of caffeine on
certain biomechanical parameters of the technique of physical exercises in circumstances
without fatigue and under neuromuscular fatigue. The study hypothesis is that caffeine
generates modifications in the technical execution of certain movements in fatigued and
unfatigued circumstances due to its physiological effects, which may be beneficial for
performance and injury prevention.
The participants will have to attend 5 sessions (enrollment, familiarization, control,
placebo, and caffeine), at least 7 days apart. In the last 3 sessions, different measurements
will be done to their technique while jumping, squatting, and running, without fatigue and
with it. Other data will be collected throughout the study to contextualize and analyze in
more detail the obtained information.
