10 mg THC
Arm Description
Delta-9-tetrahydrocannabinol (THC) free fruit snack gummy. One time, two gummies will be ingested prior to an exercise bout.
Delta-9-tetrahydrocannabinol (THC) 5 milligrams (mg) in gummy form. One time, two gummies will be ingested prior to an exercise bout.
Outcomes
Primary Outcome Measures
Comparison of Blood Lactate Levels during a 24 minute graded standard exercise test (50 watts, 100 watts, and 150 watts) to placebo.
Blood will be collected to determine Blood Lactate Levels during standard exercise following ingestion of placebo or active formula.
Comparison of Heart Rate during a 24 minute graded standard exercise test (50 watts, 100 watts, and 150 watts) to placebo.
Heart rate will be collected during standard exercise graded exercise following ingestion of placebo or active formula.
Comparison of Rating of Perceived Exertion (RPE) during a 24 minute graded standard exercise test (50 watts, 100 watts, and 150 watts) to placebo.
During standard exercise, participants will be asked to report Rating of Perceived Exertion (RPE) on a scale from 6-20 (6 is no exertion and 20 is maximal exertion) during a graded standard exercise test following ingestion of placebo or active formula.
Comparison of Indirect Calorimetry (VO2) during a 24 minute graded standard exercise test (50 watts, 100 watts, and 150 watts) to placebo.
VO2 will be collected during graded standard exercise following ingestion of placebo or active formula.
Comparison of Maximal Mean Power Output to placebo
Mean maximal power will be measured over 20 minutes following ingestion of placebo or active formula
Comparison of Time to Exhaustion to placebo
Cycling until Time to Exhaustion in seconds following ingestion of placebo or active formula

5. Study Description
Brief Summary
Lots of people, including athletes and people who like to exercise regularly, enjoy marijuana. Some people believe marijuana might improve their ability to exercise. There are no recent, up-to-date scientific studies to suggest that this belief is right or wrong. The goal of this study is to determine the influence of marijuana on exercise performance.
Detailed Description
The purpose of the proposed project is to provide athletes and the scientific community with data pertaining to the acute influence of edible marijuana on exercise performance, and the physiological responses to standardized exercise. Specifically, the investigators wish to determine: 1. The influence of edible marijuana on cardio-respiratory and metabolic responses to standardized cycle ergometer exercise. 2. The influence of edible marijuana on endurance exercise (time-trial) performance.
The investigators wish to determine if edible marijuana, ingested prior to exercise, is ergogenic (improves performance) or ergolytic (decreases performance).
The investigators hypothesize that edible marijuana will be ergolytic.
