Experimental trials

BLOOD
Baseline urine samples were analyzed for color using an 8-point Likert scale [Supplements were administered across a 30-min window. Participants then completed VAS and treatment assignment questionnaires that asked them to select which treatment they believed had been given (“oral NaHCOAfter the 10-min warm-up, blood samples were repeated. Participants commenced the team sport-specific exercise tests 120 min after applying PR Lotion (~105 min after the final set of capsules). Additional blood samples were analyzed for lactate after CMJ tests and the repeated sprints. Rating of perceived exertion (RPE; 6–20 Borg scale) was recorded after each sprint and post-Yo-Yo IR2. Blood sampling was repeated pre- and post-Yo-Yo IR2. Post-exercise urine samples, treatment assignment questionnaires, and VAS were completed after the final CMJ test. An overview of experimental procedures is shown in Experimental schematic showing timings (minutes) and procedures for warm up and battery of team sport-specific exercise tests.
