High-intensity Resistance Training May Help MS Patients With Fatigue

Three months of once-weekly sessions of high-intensity resistance training — consisting of strength exercises followed by a short recovery between sets — effectively eased fatigue in multiple sclerosis (MS) patients experiencing low energy and tiredness, a trial in Sweden shows. This intervention also lessened feelings of depression and anxiety,…

Resistance Training Can Slow MS Patients’ Brain Shrinkage, Clinical Trial Indicates

Resistance training like weight lifting can protect or even regenerate the nerve cells of relapsing-remitting multiple sclerosis patients, slowing the progression of the disease, according to a clinical trial. A hallmark of MS is the brain shrinking faster than normal, and findings from this trial indicates that resistance training can slow the shrinking or even make some brain areas grow. Research has shown that physical training benefits MS patients, helping them alleviate many symptoms, including excessive fatigue and balance control problems. Recent studies suggest that exercise can have a disease-modifying role in MS. This means physical activity can be an important adjuvant, or add-on therapy, for standard-of-care regimens. Researchers followed 35 patients with relapsing-remitting MS for 24 weeks. Eighteen patients did resistance training twice a week, consisting of four lower- and two upper-body exercises. The other 17 patients struck with their normal routines. Before and after the 24 weeks, doctors took magnetic resonance imaging scans, or MRIs, to evaluate patients' brain structures. After the 24 weeks, the scans showed less brain shrinkage in those who had resistance training. Some of their cortical brain regions were also thicker — an indication they were growing. It is not clear why exercise benefits MS patients' brains, nor if exercise has the same effect on all patients. Additional studies are needed to clarify its therapeutic effect, the researchers said. That knowledge could help improve current MS therapies.

Combined High-Intensity Interval, Resistance Training Improves Physical Health and Quality of Life in MS

In a pilot study with patients with multiple sclerosis, high-intensity interval training combined with resistance training improved physical capacity and quality of life in a pilot study of multiple sclerosis (MS) patients — whether or not they were disabled. French researchers at the University of Strasbourg assessed physical capacity, strength and quality of life before the training started, and then again after completing a 12-week exercise program. They divided participants into two groups: one of 18 patients with no disabilities, and a group of eight with disabilities. Participants followed a personalized exercise program involving both high-intensity interval training — a kind of cardiovascular exercise strategy alternating short periods of intense anaerobic exercise with less intense recovery periods — and resistance training to improve muscular strength and endurance. Scientists used a French version of the Multiple Sclerosis Quality Of Life-54 test — a questionnaire filled out by MS patients to measure health-related quality of life — with five additional questions. After the exercise program, women improved significantly in vitality, general well-being and physical health composite scores in the quality of life assessment, while men showed no significant improvements. Vitality and general well-being only improved in the group with no disability. Peak oxygen consumption improved by 13.5 percent, and maximum tolerated power — a measure of maximum energy that can be expended — by 9.4 percent. Muscle strength increased in both quadriceps and hamstrings. Women showed better improvements than men in peak oxygen consumption, maximal tolerated power, strength in both quadriceps and hamstrings, and quality of life. Both groups showed increased peak oxygen consumption and strength. “Our study has shown that high-intensity interval training combined with resistance exercise training induced an improvement in physical capacity and quality of life. Moreover, this study allowed patients, irrespective of their sex or EDSS [Expanded Disability Status Scale] score, to resume exercise autonomously,” the team wrote. "High-intensity interval training is well tolerated too and can be used in clinical rehabilitation with resistance training, in both men and women with and without disabilities."
