NCT07118514

Brief Summary

This randomized controlled trial aims to investigate the effects of a supervised resistance training program on plasma levels of Brain-Derived Neurotrophic Factor (BDNF) and irisin in individuals diagnosed with multiple sclerosis (MS). The study will also examine secondary outcomes, including fatigue, quality of life, anxiety and depression symptoms, muscular strength, and functional capacity. Participants will be randomly assigned to either an intervention or control group in a 2:1 allocation ratio. The intervention group will undergo a 12-week supervised resistance training program, while the control group will maintain their usual care without engaging in any structured exercise regimen. The trial will be non-blinded and involve assessments at baseline and after the 12-week intervention period. Eligible participants must be adults (≥18 years), of any sex, with a confirmed diagnosis of MS by a neurologist, and currently undergoing disease-modifying therapy (DMT). Participants must not be engaged in any other structured physical exercise program, though symptom-management physiotherapy will be permitted. All participants should have sufficient mobility to complete the training sessions and assessments. Exclusion criteria include the inability to perform the physical training or functional tests due to severe mobility restrictions, lack of standard pharmacological treatment for MS, or concurrent participation in other structured exercise programs.

Study Arms (2)

Exercise Group

EXPERIMENTAL

Participants in this group will undergo a 12-week supervised resistance training program, twice a week for approximately 50 minutes per session. Exercises are performed on fixed machines and based on 1-repetition maximum (1-RM) tests, with progressive loads from 50% to 65% of 1-RM. Training includes leg press, leg curl, knee extension, chest press, biceps and triceps curls, seated row, and lat pulldown

Behavioral: Progressive Resistance Training

Control Group

ACTIVE COMPARATOR

Participants in this group will engage in light stretching and relaxation sessions twice a week for 12 weeks. Each session lasts approximately 30-40 minutes and includes breathing exercises, stretching of major muscle groups, and guided relaxation.

Behavioral: Stretching and Relaxation Activities

Interventions

A 12-week supervised resistance training program, performed twice weekly for 50 minutes per session. Exercises are based on 1-repetition maximum (1-RM) tests, using fixed machines and progressive loads (50-65% of 1-RM). Exercises include leg press, leg curl, knee extension, chest press, biceps/triceps curls, seated row, and lat pulldown.

Also known as: Resistance training, Weight Training, Strength Training
Exercise Group

A 12-week supervised program focused on flexibility and relaxation, performed twice weekly for approximately 50 minutes. Includes static stretching of major muscle groups and guided breathing exercises aimed at reducing muscle tension and promoting mental relaxation.

Also known as: Static Muscle Stretching, Dynamic Stretching, Flexibility Protocols
Control Group
