Energetic Response to Feeding and Exercise in SCI (CRIT)
Spinal Cord Injuries
About this trial
This is an interventional prevention trial for Spinal Cord Injuries focused on measuring postprandial, glycemia, lipemia, macronutrient metabolism, physical activity
Eligibility Criteria
Inclusion Criteria:
- Adult (>/=18 years of age)
- Neurologically stable chronic (>/= 1year) spinal cord injury (SCI)
- American Spinal Injury Association Impairment Scale (AIS) grade A, B, or C
- SCI at level </= the first thoracic vertebrae (T1)
Exclusion Criteria:
- Being of ≤ 18 years of age.
- Contraindication to exercise (ACSM Guideline, 10th edition)
- Lower extremity fracture or dislocation within 6 months of participation,
- History head injury or seizures.
- Inability to consent.
- Restrictions in upper extremity range of motion that would prevent an individual from achieving an unhindered arm cycling motion or moving throughout a range needed to perform resistance maneuvers.
- A pressure ulcer at ischial/gluteus, trochanteric, sacral, or heel sites within the last 3 months.
- Pregnancy determined by urine testing in sexually active females.
- Imprisonment in state or federal jail or prison.

Seated control (CON)
Circuit resistance training (CRT)
Moderate intensity continuous (MICT)
High intensity interval training (HIIT)
Participants remain seated in their habitual wheel chair for ~45 min (duration of exercise performed in other arms). Following the intervention they are fed.
Participants complete upper extremity resistance maneuvers (lifts) interspersed with low-load/high-speed arm cycling for a combined 30 repetitions of 6 lifts and ~20 min of arm cycling. During this time energy expenditure is measured via open-circuit indirect calorimetry. Following the intervention they are fed.
Participants complete continous arm cycling at a steady-state power output (intensity) matched to the energy expenditure (kcal/min) and duration of exercise (min) response during CRT. Following the intervention they are fed.
Participants complete interval arm cycling at power output that varies between 2 min "active" and two min "recovery" periods. This interval exercise is matched to the total energy expenditure (accumulated kcals) response during CRT. Following the intervention they are fed.
