|Acute effect||Effect on performance||THC dose||Reference|
|Resting heart rate and both systolic/diastolic blood pressure were significantly elevated at rest||Physical work capacity at a heart rate of 170 decreased by 25% compared to placebo||18.2 mg of Δ9-THC||Steadward and Singh |
|Induced tachycardia at rest||VE, VO2 and VCO2 were increased above control at ≥50% max effort; Small, but significant reduction in maximal exercise duration; tachycardia up to 80% of maximum effort and during recovery||7 mg/kg marijuana (containing 1.7% Δ9-THC)||Renaud and Cormier |
|Increased heart rate and the rate-pressure product at rest||No effect on blood pressure, ventilation or oxygen uptake during submaximal exercise (15 min at 50% of VO2max); increased heart rate and the rate-pressure product during recovery||Smoking 7.5 mg of Δ9-THC||Avakian et al. |
