Effects of Resistance Training in Multiple Sclerosis: a Randomized Trial.

Multiple sclerosis is a dysimmune and neurodegenerative disease of the central nervous system. Despite highly effective drug, multiple sclerosis represents the main cause of non-traumatic disability in young people. Interventions based on physical exercise have a positive impact on the course of the disease, although the pathophysiological mechanisms responsible for this benefit remain unknown. This project aims to investigate the impact of physical exercise on neuronal destruction in patients with multiple sclerosis. To do this, the investigators will study the evolution of the concentrations of two markers of neuronal injury, acidic gliofibrillary protein (GFAP) and light chain neurofilaments (Nfl) in two groups of patients: a control group and a second group subjected to a supervised resistance physical exercise program performed during 10 weeks. Marker values will be compared before and after the intervention and between groups. The results will allow the investigators to delve into the pathophysiology of multiple sclerosis and the mechanism through which physical exercise impacts on the disease. In addition, the investigators will generate knowledge that will allow us to reinforce the idea of integrating physical exercise as part of the treatment in multiple sclerosis.
