Physical activity has become a first-line treatment in rehabilitation settings for individuals with chronic pain. However, research has only recently begun to elucidate the mechanisms of exercise-induced analgesia. Through the study of animal models, exercise has been shown to induce changes in the brain, spinal cord, immune system, and at the site of injury to prevent and reduce pain. Animal models have also explored beneficial effects of exercise through different modes of exercise including running, swimming, and resistance training. This review will discuss the central and peripheral mechanisms of exercise-induced analgesia through different modes, intensity, and duration of exercise as well as clinical applications of exercise with suggestions for future research directions.

Background: Exercise-induced hypoalgesia (EIH) is characterized by a reduction in pain perception and sensitivity across both exercising and non-exercising body parts during and after a single bout of exercise. EIH is mediated through central and peripheral mechanisms; however, the specific effect of muscle contraction alone on EIH remains unclear. Moreover, previous studies on electrical muscle stimulation (EMS) have primarily focused on local analgesic effects, often relying on subjective pain reports.

Introduction: Exercise-induced hypoalgesia (EIHypo) among healthy individuals is well documented; however, the opposite effect of exercise, ie, exercise-induced hyperalgesia (EIHyper), has mainly been described in patients with chronic pain or after intense/painful exercise.
Objectives: We investigated the extent to which EIHypo and/or EIHyper occur among healthy participants and whether these responses are associated with individuals' pain modulation capacity.
Methods: Fifty-seven participants (mean age 29.

Background: Vagal activity has analgesic effects that are attributed to exercise-induced hypoalgesia (EIH). High vagal tone and low pain sensitivity are reported in individuals who routinely exercise yet, their association is unclear. Furthermore, it is unknown if the heightened vagal tone following high physical activity predicts and intensifies EIH.

To understand the neuroscience of pain relief, one must know about the descending pain modulatory system. Neuronal pathways that originate in the brainstem and project to the spinal cord to modulate spinal neuronal activity provide a well-documented perspective on the mechanisms of analgesia that underpin pharmacological and nonpharmacological treatment options for people with musculoskeletal pain. Peripheral stimuli or signals from the cortex and subcortical regions of the brain can trigger the descending pain modulatory system (DPMS).
