Neural
Caffeine intake led to lower ratings of perceived exertion (RPE) for back squat and deadlift exercises.
Caffeine can help athletes feel less exertion during heavy lifts, potentially improving performance.
StrongSupportsmedium confidence
For RPE, there was a main effect of condition where CAF intake led to lower scores for back squat (p = 0.003) and deadlift (p = 0.042).
Why this rating
Based on the randomized, placebo-controlled, cross-over study design.
