Conditions
Brief summary
This study will evaluate if Ursolic Acid supplementation may be effective in reducing muscle loss and improving blood sugar control in the SCI community.
Interventions
Subjects will take an oral 400mg (8 capsules - 4 in the morning/200mg and 4 at night/200mg) supplement of UA every day for 12 weeks.
Subjects will perform 3 sets of 10 repetitions of concentric and eccentric upper body exercises (bicep curls and tricep extensions) each session. Each session will last approximately 10-15 minutes of weightlifting with a 2-minute rest period between sets. The arm selected for exercise will be randomized.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Muscle Mass Using Dual X-ray Absorptiometry (DXA) | Baseline, 12 weeks | Changes in muscle mass in grams as measured by Dual X-ray Absorptiometry |
| Changes in Peak Isokinetic Strength | Baseline, 12 weeks | Peak strength (peak torque in ft-lb) of both arms at 90 degrees range of motion will be tested in elbow flexion and extension (at 60 deg/s) on a Biodex dynamometer |
| Changes in Fasting Insulin Resistance (IR) | Baseline, 12 weeks | Changes in IR using Homeostatic Model of Assessment (HOMA) v2 model estimates steady state beta cell function and insulin sensitivity as percentages of a normal reference population. The change in resting IR will be measured by (fasting serum glucose\*fasting serum insulin/22.5). Lower values indicate a higher degree of insulin sensitivity. |
| Changes in Glucose Disposal | Baseline, 12 weeks | Changes in glucose disposal will be measured by the Oral Glucose Tolerance Test (OGTT) using Trutol glucose solution of 75 grams. The rates of glucose disposal will be defined by the area under the glucose challenge curve (AUC). |
