Physical exercise is increasingly being promoted by healthcare for chronic pain conditions with beneficial outcomes such as: pain and fatigue reduction, and increased quality of life. Nevertheless, knowledge about biochemical consequences of physical exercise in chronic pain is still relatively poor.The endocannabinoid system has been suggested to play a role for acute exercise-induced reward and pain inhibition. The aim of this study is to investigate the chronic outcomes of resistance exercise on levels of endocannabinoids and related lipids in fibromyalgia (FM).
