Clinical Trial Summary

The study seeks to investigate whether 24 weeks of power training has neuroprotective effects in older PwMS. Additional purposes are to examine the effects of 24 weeks power training on physical function, cognitive function and neuromuscular function. Further, it is investigated whether the potential effects of power training are maintained after 24 weeks of follow-up.


Description:

Over the past 3-4 decades, the lifespan among people with multiple sclerosis (MS) has increased substantially. Today more than one-third of all people with MS are 60 years or older. With advanced age, people with MS are more likely to have impairments in cognitive and physical function. Positive adaptations within the nervous system (~neuroplasticity) have been shown to occur in people with MS following periods of resistance training (RT). This resembles the observations in young and old healthy individuals. Moreover, a specific type of RT termed power training appears to be particularly beneficial, as it emphasizes an explosive concentric phase of muscle contraction. This taxes the nervous system to a very high extent. As a result, power training has been shown to improve several aspects that rely on the nervous system in older individuals without MS. These aspects include cognition, neuromuscular function, and physical function. The investigators speculate that older people with MS would also benefit. However, no studies have looked into the effects of power training in older people with MS.

Intervention

Other:
Power training
First a brief warm up on a stationary bike and uni-lateral knee raises is completed. Power training: Involves exercises performed with fast/explosive muscle contraction during the concentric phase, and slow/controlled (approximately 2-3 s) muscle contraction during the eccentric phase. Functional- and balance exercises are included from week 9-24. Progression: Week 1-4: 3 sets of 12 repetitions at a load of 14 repetitions maximum (RM) with focus on introducing resistance exercise and familiarizing participants with exercises. Week 5-8: 3 sets of 12 repetitions at a load of 14 RM the power training component. Week 9-16: 3 sets of 10 repetitions at a load of 12 RM. Week 17-24: 3 sets of 8 repetitions at a load of 10 RM Strengthening exercises: Bilateral leg-press Bilateral plantar flexion Bilateral knee extension Unilateral banded dorsal flexion Bilateral lying leg curl Back extension Shoulder press Seated row Chest press Lat pull-down
