Abstract: According to the World Health Organization (WHO), 47 million people display mental
health disorders Worldwide. In addition, epidemiological studies have shown that the extension of life
expectancy and the increase in aged population will significantly impact the prevalence of several
mental impairments. Although there are strategies for preventing and alleviating mental illnesses, such
as pharmacological and psychological approaches, limited results have been observed. Thus, the search
for new therapeutics for managing psychiatric disorders has explored multiple roads. In recent years, it
has been demonstrated that physical activity and exercise promote health benefits. On the other hand,
among the neurobiological systems that participate in the genesis and development of mental disruptions,
the endocannabinoid system has been suggested as an active player. Supporting this hypothesis,
data suggest that the elements comprising the endocannabinoid system, such as the CB1/CB2 cannabinoid
receptors, endogenous ligands (N-arachidonoylethanolamine [anandamide, AEA] and 2-
arachidonoylglycerol [2-AG]), transporters and the enzymes involved in the biosynthesis and degradation
of the AEA and 2-AG, modulate mental diseases. In this review, we discuss that the endocannabinoid
system might be considered as a modulator for the positive outcomes of exercise in the management
of mental disorders. Clinically, this promising field might be exploited by targeting the elements
of the endocannabinoid system aimed to increase the exercise benefits applied to patients with
mental illnesses.
