Brief summary
This is a longitudinal study to examine the effects of a short-term training program on neurofilamet and GFAP plasma levels. Participants will be divided in two groups: control group (moderate aerobic training) and active group (resistance training). The change in biomarkers will be analyzed pre and post intervention in both groups. Differences between groups will be also evaluated by investigators.
Detailed description
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.

Interventions
OTHERResistance training
The experimental group (ACTIVE GROUP) will perform a circuit-based muscular strength program at high intensity three days per week for 10 weeks. Each session will last approximately 45 minutes. The Resistance training program will be supervised by staff from the Department of Health Sciences and Sports of the Miguel de Cervantes European University of Valladolid and will be carried out at the facilities of the Miguel de Cervantes European University of Valladolid.
OTHERLow aerobic training
Patients assigned to this group will perform exercise in static bicycle during 45 minutes three days a week, with a duration of 10 weeks. This second group, despite performing the aerobic exercise, is considered control, since they will perform low-intensity aerobic exercise (50% of the maximum power developed in cycloergometer) The Resistance training program will be supervised by staff from the Department of Health Sciences and Sports of the Miguel de Cervantes European University of Valladolid and will be carried out at the facilities of the Miguel de Cervantes European University of Valladolid.

Masking description
A double-blind system will be maintained in which the exploring neurologists and the patient will not know the assigned therapeutic group. Randomly assigned to one or the other group.
Intervention model description
We will include patients with multiple sclerosis in the ACTIVE GROUP (resistance training) and patients with multiple sclerosis CONTROL GROUP (low intensity aerobic training).
