Muscle aging and response to exercise in older adults with multiple sclerosis

Skeletal Muscle Aging and Responsiveness in Aged People With MS

Not applicable Interventional Oklahoma Medical Research Foundation · NCT07500727

This study will test whether a combined cardio and strength exercise program improves muscle health and fitness for people with MS who are 60 or older compared with similar people without MS.

What this trial studies

The investigators will first compare baseline muscle and cardiovascular health in adults aged 60 and older with MS to age-matched people without MS. Participants will then complete a combined cardiovascular and resistance training program with visits about three times per week, roughly 1.5 hours per visit, for approximately four months. The study will measure whole-body and muscle-specific changes, including differences between a more affected and a less affected leg in people with MS, and cardiorespiratory fitness (VO2max). Results will show whether older adults with MS adapt to exercise differently than age-matched peers without MS.

Who should consider this trial

Good fit: Adults aged 60 or older with a diagnosis of MS, EDSS 2.0–5.5, cognitively able to consent, not currently in a structured exercise program, and without unmanaged chronic diseases are ideal candidates.

Not a fit: People with severe disability outside the EDSS range, unmanaged cardiopulmonary or metabolic diseases (including diabetes or liver disease), recent chemotherapy, those taking metformin, or other conditions that limit safe exercise are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, participants could gain stronger, healthier muscles, better cardiovascular fitness, and improved day-to-day mobility.

How similar studies have performed: Exercise trials in younger and middle-aged people with MS have shown benefits for strength and fitness, but few studies have focused on people over 60, so this approach is partly supported but relatively novel in this age group.
