Study Design Participants completed two treatment sessions involving the oral administration of CBD (300 mg) or a placebo in a randomised, double-blind, crossover design. Each session involved seven consecutive blocks of testing: Baseline (pre-treatment), Pre-RUN 1 (+ 60–90 min post-treatment), RUN 1 (+ 90–150 min), Post-RUN 1 (+ 155–170 min), RUN 2 (+ 180– approx. Participants were not permitted to consume fluid during exercise but received up to 500 mL of water on completion of the Post-RUN 1 and 2 assessments; again, individual intakes were recorded and replicated across sessions. Respiratory gases were sampled continuously between 24–32 (24 EX ), 37–45 (37 EX ) and 50–58 (50 EX ) min of exercise. Respiratory gases were sampled during the final ~ 5 min of exercise (i.e. from the point at which HR exceeded ~ 90% HR max , as determined during the initial V̇O 2max test).
