Purpose: Various psycho-physiological effects are promoted by physical exercise, including modulation of pain perception. Assuming central opioidergic mechanisms, we expected physical exercise (two hours outdoor run) to affect the affective dimensions of pain processing, as compared to a control condition (two hours outdoor walk). Materials and Methods: Thermal heat-pain fMRI was performed in 20 athletes (mean age 39 years, range 23–59 years) before and after both interventions. The paradigm consisted of 2×5 blocks of 30sec stimulation phases (5x heat pain, 46.5°C/5x non-painful heat, 43.0°C). Examinations were…
