Number of participants that the trial has enrolled

12

Results

Paired running attenuated the exercise-induced increase in fatigue and the reduction in plasma AEA levels. AEA was identified as a moderator buffering the fatigue-induced deterioration of negative affect; notably, this adverse association was significantly mitigated in high AEA responders.

Baseline Characteristics

Participants were healthy non-smokers with no history of abnormalities in medical examinations, current medication use, or vasovagal syncope during blood sampling. The physical characteristics of the participants were as follows: age, 21.2 (0.4) years; height, 172.8 (6.4) cm; weight, 68.3 (9.0) kg; and body mass index (BMI), 22.9 (2.1) kg/m2 (mean [SD]).

Participant flow

A priori statistical power analysis using G*Power 3.1.9.7 indicated that a sample size of 12 was necessary to detect.

Adverse events

No adverse events were reported during the study.

Outcome measures

Plasma endocannabinoid concentrations
Heart rate
Rating of perceived exertion
Mood index (Physical Activity Affect Scale)
