People with MS working to strengthen cognitive functions, such as learning and memory, may reap greater benefits from walking on a treadmill than from stretching and toning, according to a recent study.
Researchers investigated the effects of treadmill-walking on the hippocampus — a critical brain area for cognition — for people with relapsing-remitting MS. One target of MS is the hippocampus. Damage to this brain area can reduce its size and damage functions in learning and memory.
Before and after completing 12 weeks of either treadmill walking or a low-intensity exercise, study participants underwent a series of neuropsychological tests to look at learning and memory function. The researchers found that people who walked on a treadmill showed greater verbal learning and memory improvement than those who did not.
For the study, participants also underwent brain scans, allowing researchers to observe any changes in hippocampal volume before and after the 12-week exercise regimen.
The researchers had hypothesized that, after walking on a treadmill, participants would see improvements in their learning and memory, as well as to their hippocampal volume. However, the team found the hippocampal volume remained the same. People who did low-intensity exercise, such as stretching, showed decreased hippocampal volume.
