About this study
Official title: Exercise Treatment of Obesity-Related Secondary Conditions in Adults With Paraplegia
This hypothesis-driven study will investigate effects of physical activity with or without a nutrient supplement known to increase body lean mass in adults with chronic paraplegia who have clusters of obesity and obesity-related secondary complications.
Read the detailed description
Obesity and obesity-related secondary complications are pandemic health hazards that are highly prevalent among persons with spinal cord injuries (SCI). Accumulation of body fat disposes persons with SCI to accelerated endocrine and cardiovascular diseases, as well as pain, functional decline, and diminished health-related quality of life (HRQoL). While use of combined resistance and endurance exercise by persons without disability can remedy many of the problems associated with these disorders, their widespread use for persons with spinal cord injuries (SCI) must first satisfy scientific burdens of effectiveness.
The investigators have adopted the term "obesity-related secondary complications" to describe accumulation of body fat clustering with other secondary CVD risks, while recognizing that a threshold criterion for diagnosis of obesity in persons with SCI remains ill-defined. For purposes of this proposal, the "-related" part of the term confers physical deconditioning, hypertension, fasting dyslipidemia, post-prandial lipemia (PPL), and impaired insulin sensitivity, all of which have been reported in persons with SCI. Contextualized, any of these risks occurring independently or in clusters would be cause for immediate therapeutic lifestyle intervention (TLI), if not frank medical treatment. Given our early understanding of effective treatments for these risks, any improvement in their severity would be CVD risk-reducing and thus life-benefiting and function-preserving.
The investigators expect that the research findings will improve the understanding of risks for obesity and obesity-related secondary complications so that future interventions can be better targeted, identify an exercise intervention that can attend to current health risks, clarify whether nutrient supplementation improves risk-lessening benefits of exercise, identify exercise timing and intensities that best enhance fat utilization, and expand the understanding of the interrelated nature of risk factors after SCI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ExerciseOther
Also called Circuit Resistance Training (CRT)
CRT will occur 3 times per week for 26 weeks. Each training session will last approximately 40-45 minutes and employ resistance training (weight lifting) and high-speed, low intensity endurance activities (arm cranking) with interposed periods of incomplete recovery (i.e., heart rate not falling to baseline).
| Study group | Role | What they receive |
|---|---|---|
| Supplement | Experimental | Participants randomized to the 'supplement' arm will consume a blended drink containing 48g of ionexchange, hydrolyzed vanilla-flavored whey protein (Whey to Go, Solgar Vitamin and Herb, Leonia, NJ; 3g CH2O, < 3g Total Fat). The drink will be given in split doses immediately before and after each training session, which represents a timing schedule that best stimulates muscle anabolism in persons undergoing exercise training. Receives: Other: Exercise |
| Placebo | Placebo comparator | As ingestion of the protein supplement is critically influenced by time of administration, participants assigned to the 'placebo' study arm will consume the identical supplement and dose on days during which training is not performed. This strategy will allow the groups to be isocaloric and equal in protein supplementation. Receives: Other: Exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Global cardiovascular disease risk score
Global cardiovacular disease risk will be generated by evaluating blood metabolism in the fasting and fed state for inflammatory disease markers including total cholesterol: high density lipoprotein ratio (TC: HDL ratio), post-prandial lipemia (PPL), whole body fat oxidation (WBFO), insulin resistance, and inflammatory mediators.
Measured: 4 visits over 9 months
Secondary outcomes (3)
Body composition
The percent of muscle and fat in each participants' body will be measured by dual x-ray absorptiometry (DEXA) scan.
Measured: 4 visits over 9 months
Cardiovascular Endurance
Endurance will be measured using a calibrated upper arm ergometer. An initial exercise workload of 0 Watts at 60 revolutions per minute (RPM) for three minutes will be followed by three minute stages increasing in 20 Watt increments. Responses to exercise will be continuously monitored via open-circuit spirometry and 12-lead electrocardiography. Peak Work will be defined as volitional fatigue, inability to maintain targeted workload, or the point at which increasing workload fails to further increase VO2.
Measured: 4 visits over 9 months
Muscular strength
Upper extremity dynamic strength testing will be performed on a Helms equalizer 1000 multi-station exerciser using the following maneuvers: overhead press, horizontal row, vertical butterfly, biceps curl, latissimus pull down (either to the chest or neck), and dips. The 1-repetition maximum (1-RM) will be calculated using the Mayhew regression equation.
Measured: 8 visits over 9 months

Questions about this trial
What is this clinical trial studying?
A study testing Exercise in people with Spinal Cord Injury, run by University of Miami at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Global cardiovascular disease risk score (time frame: 4 visits over 9 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2015.
