Abstract
Caffeine functions as an adenosine receptor antagonist by blocking pain reception. However, research is warranted to examine the efficacy of caffeine on delayed onset of muscle soreness (DOMS). PURPOSE: This study investigated the effects of caffeine on 5km time trial performance following exercise-induced muscle soreness. METHODS: Recreationally trained male participants (n=9) completed a 30min downhill run at 70% VO2max to induce muscle soreness. Participants returned to the lab 48 h after the downhill run to complete a 5k-time trial (TT). Using a double blind, counterbalanced design the participants ingested either the placebo (5mg/kg) (PLB) or caffeine (5mg/kg) (CAFF) 1h prior to the 5km TT. RPE was recorded every 2 min during each minute of the TT. A repeated measures ANOVA (treatment x time) was used to analyze dependent measures. RESULTS: There was no interaction for the treatments (PLB, CAFF) across time for RPE or heart rate. No significant difference was detected for 5k performances between trials (1036.2 ± 92.6 sec vs. 1043 ± 91.9 sec for CAFF and PLB, respectively). There was no difference between CAFF and PLB trials for RF muscle soreness (p = .216) or VMO muscle soreness (p = .679). These findings of similar physiological and pain responses between trials suggest that caffeine has a limited ergogenic effect after severe muscle damage on subsequent sustained maximal exercise performance.
