Exercise and SCI
Most people exercise to improve their appearance and self-esteem, increase their physical endurance and strength, relieve stress or simply to become healthier. Although spinal cord injury can make it somewhat harder, it need not make it impossible.
When you have SCI it is much harder for you to burn off calories as effectively as someone without paralysis.
The major factor that makes it harder for your body to burn off calories is the loss of muscle mass. Muscle burns calories even when your body is at rest. So for a spinal cord injured person, your resting metabolism can be as low as half that of a person without a SCI.
So even though you may exercise regularly, you will burn significantly fewer calories than an able-bodied person performing the same exercise.
