RT Journal Article SR Electronic T1 Endocannabinoids and exercise JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 536 OP 541 DO 10.1136/bjsm.2004.011718 VO 38 IS 5 A1 Dietrich, A A1 McDaniel, W F YR 2004 UL http://bjsm.bmj.com/content/38/5/536.abstract AB Exercise induces changes in mental status, particularly analgesia, sedation, anxiolysis, and a sense of wellbeing. The mechanisms underlying these changes remain unknown. Recent findings show that exercise increases serum concentrations of endocannabinoids, suggesting a possible explanation for a number of these changes. This article provides an overview of this emerging field.
