Study: NCT04149717

Intervention type: DIETARY_SUPPLEMENT
Group type: EXPERIMENTAL
Intervention: Energy Drink Ingredients and Exercise
Description: Subject will ingest 500 mL of one of three test solutions:~A) sucrose (150g) B) sucrose (150g); caffeine (400 mg) C) sucrose (150g); caffeine (400 mg); taurine (4,000 mg); carnitine (400 mg) 3. 30 min later, subject will exercise on a treadmill using the Bruce Protocol maximum exercise test (https://www.aopa.org/go-fly/medical-resources/health-conditions/heart-and-circulatory-system/bru...). For one additional session, subjects will receive test solution C without exercise.~4. Each stage will last 3 minutes. Stage 1 = 1.7 mph at 2% Grade Stage 2 = 2.5 mph at 4% Grade Stage 3 = 3.4 mph at 6% Grade Stage 4 = 4.2 mph at 8% Grade Stage 5 = 5.0 mph at 10% Grade Stage 6 = 5.5 mph at 12% Grade Stage 7 = 6.0 mph at 14% Grade Stage 8 = 6.5 mph at 15% Grade Stage 9 = 7.0 mph at 15% Grade. The test will end when subjects reach exhaustion.~5. 1, 2, and 4 hrs following ingestion, HR, BP, and EKG will be recorded.
