caffeine — decreases time-trial completion time
Evidence strength: very limited.Findingreplicated ×5“The primary statistical analysis using data from the caffeine trials revealed that caffeine gum reduced parkrun finishing time by 17.28 s (95% CI 4.19, 30.37; t (13) = – 2.85, P = 0.01).”

- crossover
- Participants
- 14
- Dose
- 300 mg caffeine (three pieces of gum, each analysed at about 92 mg) chewed for 5 min, starting 30 min before the 5 km parkrun, single dose per run
- Population
- Fourteen recreational runners capable of running 5 km in under 25 min, completing the caffeine-gum and placebo-gum crossover over two Saturday parkruns (self-paced 5 km, outdoor mass-participation event); habitual caffeine consumers

caffeine — decreases rating of perceived exertion
Evidence strength: insufficient.Findingreplicated ×4“RPE at the end of each parkrun was significantly lower after caffeine gum than placebo gum (15.43 v 16.64, mean difference – 1.21 95% CI – 0.30, – 2.13; P = 0.01).”
