Abstract

Exercise is rewarding, and long-distance runners have described a runner's high as a sudden pleasant feeling of euphoria, anxiolysis, sedation, and analgesia. A popular belief has been that endogenous endorphins mediate these beneficial effects. However, running exercise increases blood levels of both β-endorphin (an opioid) and anandamide (an endocannabinoid). Using a combination of pharmacologic, molecular genetic, and behavioral studies in mice, we demonstrate that cannabinoid receptors mediate acute anxiolysis and analgesia after running. We show that anxiolysis depends on intact cannabinoid receptor 1 (CB1) receptors on forebrain GABAergic neurons and pain reduction on activation of peripheral CB1 and CB2 receptors. We thus demonstrate that the endocannabinoid system is crucial for two main aspects of a runner's high. Sedation, in contrast, was not influenced by cannabinoid or opioid receptor blockage, and euphoria cannot be studied in mouse models.

  • Exercise-induced elevations of endocannabinoid levels have been proposed to account partially for anxiolytic, anti-nociceptive and neuroprotective properties of exercise.

    “Exerciseinduced elevations of endocannabinoid levels have been proposed to account partially for anxiolytic (Tantimonaco et al., 2014;Fuss et al., 2015), anti-nociceptive (Galdino et al., 2014) and neuroprotective (Hill et al., 2010a) properties of exercise, which are all responses that instead are affected in a negative direction by sleep loss (e.g.Roy-Byrne et al., 1986;Schuh-Hofer et al., 2013;”
  • In mice, central and peripheral CB1 and CB2 receptors are necessary for inducing anxiolysis and analgesia after running.

    “Indeed, recent research suggests that at least in mice, central and peripheral CB1 and CB2 receptors are necessary for inducing anxiolysis and analgesia after running (Fuss et al., 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
