Many persons with Multiple Sclerosis ( MS) have problems with memory and thinking.Exercise has been shown to improve memory and thinking in persons with diseases such as Alzheimer's. This study will investigate whether a program of aerobic exercise can improve memory and thinking in persons with MS

Arms Assigned Interventions
Experimental: aerobic exercise
Subjects will train on a recumbent cross trainer 20-30 minutes/session for three times/week for six months under supervision of a fitness specialist
Behavioral: exercise
subjects will participate in one of two forms of exercise
Active Comparator: stretching
Subjects will particiate in supervised stretching at same frauency, duration and intensity of aerobic exericse arm
Behavioral: stretching
subjects will particiopate in supervised stretching as described in arm description.

Detailed Description:

Persons with Multiple Sclerosis(MS)will be screened for eligibility and randomized to a protocol with two intervention arms. One group will have aerobic training on a recumbent cross trainer three times a week for 20-30 minutes/session. The other group will participate in stretching exercises at the same frequency and intensity.Total training time will be six months.Outcome measures will include tests of memory and thinking, and fitness measures.
