Brief Summary:

Currently, those with spinal cord injury (SCI) demonstrate increased prevalence of obesity (75%) cardiovascular disease (30 - 50%), type II diabetes (21%) and osteoporosis in the legs (100%) when compared to the general population. It is important to identify the modes and intensities of exercise most likely to generate a reduction in these inactivity-related diseases in this population.

Therefore, the main purpose of this pilot research project is to implement and test a form of a spinal cord injury-specific exercise, known as FES rowing (FES: functional electrical stimulation).

Arm Intervention/treatment
Experimental: Functional electrical stimulation rowing
Using an Odstock 4 channel neuromuscular stimulator with Concept 2 Rower
Device: Functional electrical stimulation rowing (Odstock 4 channel neuromuscular stimulator with Concept 2 Rower)
Participants will strengthen their quadriceps and hamstrings using electrical stimulation for up to 12 weeks (using an Odstock 4 channel neuromuscular stimulator). Then participants will use a seated rower (Concept 2 Rower, fitted with a backrest that allows those with spinal cord injury to engage in rowing) in conjunction with the electrical stimulation for 12-24 weeks.

Primary Outcome Measures :
  1. Peak VO2 (volume oxygen) output during exercise [ Time Frame: 24 weeks compared to baseline ]
    Peak VO2 testing will be performed before beginning rower training and again at the end of the 24 weeks of training. Testing will be performed with an arm ergometer, rowing without electrical stimulation, and rowing with electrical stimulation. This will assess energy use, time to fatigue, and perceived exertion.

Secondary Outcome Measures :
  1. Body composition [ Time Frame: 24 weeks compared to baseline ]
    Participants will have their body composition (specifically leg percent fat and muscle, and bone mineral density) measured before beginning training and at the end of the 24 weeks of training.

  2. Leg EMG (electromyogram) while rowing [ Time Frame: Throughout study (up to 36 weeks) ]
    Participants will perform the rowing exercise while having EMG of multiple leg muscles.
