Brief summary
The purpose of this study is to test different types of exercise training for people with multiple sclerosis (MS). The exercise program is based on physical activity guidelines that have been developed specifically for people with MS. The investigators believe these guidelines will be effective for improving physical fitness and function in persons with mild-to-moderate MS.
Detailed description
Most adults with multiple sclerosis (MS) are physically inactive. One approach to address physical inactivity in this population has involved the provision of physical activity guidelines. Such physical activity guidelines are an important tool for exercise prescription, promotion, and monitoring, and recommend that people with MS participate in at least 30 minutes of moderate intensity aerobic activity 2 times per week and strength training exercises for major muscle groups 2 times per week. The guidelines were developed from a systematic literature review and have yet to be tested for efficacy in improving fitness or other outcomes. This study will test that efficacy of aerobic and resistance training alone and in combination (based on the MS physical activity guidelines) for improving physical fitness and other outcomes (e.g., walking, thinking, MS symptoms) in persons with MS who have mild-to-moderate disability. Such an examination will be important to confirm the efficacy of the exercise prescription for people with MS and health-care providers. The investigators will further perform an exploratory analysis of blood biomarkers and eye imaging parameters to examine some of the mechanisms of exercise training effects in persons with MS.
Interventions
BEHAVIORALResistance exercise
strength training consists of 1-3 sets , 10-15 repetitions of 10 exercises targeting lower body, upper body and core muscle groups
BEHAVIORALStretching exercise
The stretching condition will consist of 1-3 sets, 30-40 seconds of 12 stretching movements targeting lower body, upper body, and core areas performed 2 days per week.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physical activity | 0 and 6 months | an accelerometer along with the Godin Leisure Time Physical Activity Questionnaire and 7-day Physical Activity Recall Questionnaire will be used to measure physical activity. |
| Physical fitness (aerobic and muscular) | 0 and 6 months | Physical fitness determined by VO2 peak using a computer-driven cycle ergometer Muscular fitness determined by a seated dynamometer machine for leg strength and a hand dynamometer for upper body strength |
| Walking and physical function | 0 and 6 months | A timed 25-Foot walk, a 6 -minute walk, walking on a GaitRite electronic walkway, 9-hole peg test and the use of a force platform will measure walking and physical function. |
| Cognition | 0 and 6 months | The Brief International Cognitive Assessment for MS battery will be used. |
| Patient-rated outcomes | 0 and 6 months | Self reporting questionnaires on fatigue, mobility, anxiety, depression, QoL, and social cognitive theory variable (e.g. Exercise Self-Efficacy Scale, Late-life function and disability scale) |
Secondary
| Measure | Time frame | Description |
