Summary
Weightlifting is a high-intensity strength-power sport where performance depends on maximal force, power output, and technical execution in the snatch and clean and jerk. Due to the sport's short-duration efforts, the ATP-PCr system predominates, with glycolysis supporting recovery between attempts. Given these demands, ergogenic aids are commonly used. While some supplements show limited or inconsistent evidence, caffeine stands out as one of the most well-supported for enhancing strength and power, mainly through central nervous system stimulation. Although its benefits are well documented in other strength sports, research specifically in Olympic weightlifting is scarce. Therefore, this study aimed to examine the effects of caffeine on neuromuscular and competition performance in elite weightlifters, hypothesizing a positive effect.
