Abstract: An emerging trend in sports nutrition is the consumption of energy drinks and "energy shots". Energy shots may prove to be a viable pre-competition supplement for runners. Six male runners (mean ± SD age and VO2max: 22.5 ± 1.8 years and 69.1 ± 5.7 mL·kg-1·min-1) completed three trials [placebo (PLA; 0 mg caffeine), Guayakí Yerba Maté Organic Energy Shot™ (YM; 140 mg caffeine), or Red Bull Energy Shot™ (RB; 80 mg caffeine)]. Treatments were ingested following a randomized, placebo-controlled crossover design. Participants ran a five kilometer time trial on a treadmill. No differences (p > 0.05) in performance were detected with RB (17.55 ± 1.01 min) or YM ingestion (17.86 ± 1.59 min) compared to placebo (17.44 ± 1.25 min). Overall, energy shot ingestion did not improve time-trial running performance in trained runners.
