Caffeine as a efficiency enhancer
Caffeine, identified for its stimulating results on the central nervous system, has lengthy been acknowledged for its potential to reinforce athletic efficiency. World Athletics even recommends it as a efficiency enhancer. Up to now, most analysis on caffeine and efficiency was achieved on cyclists, with research on sprinters and endurance runners solely not too long ago (with optimistic outcomes).
On this context, the examine targeted on 36 leisure runners able to finishing a 5K run in beneath 25 minutes. The runners had been a part of a double-blind, placebo-controlled intervention, exploring whether or not chewing caffeine-infused gum may contribute to improved parkrun efficiency.

Chewing towards a PB
The runners, randomly assigned to both caffeine or placebo gum teams, engaged in a five-minute gum-chewing session half-hour earlier than every parkrun, to permit the caffeine to take impact. The outcomes revealed a noteworthy enchancment in 5K efficiency, with a median time discount of 17.28 seconds amongst these chewing the caffeine gum.
This enhancement in efficiency was additional mirrored in a lower within the runners’ RPE (charge of perceived exertion) by 1.21 models in comparison with the placebo group. This aligns with analysis on caffeine and endurance athletes, the place scientists noticed that caffeine might “inhibit perceptual response throughout train,” which means members had an elevated capacity to tolerate discomfort related to fatigue whereas operating.
Whereas extra analysis must be achieved to find out the utmost greatest efficient doses for runners, it’s clear that including a caffeinated increase to your parkrun race prep might enable you to as you chase that PB.
