실험적: Hyperglycemia
Hyperglycemia (rest controlled) will be induced by i.v.
injection of 25 mL of dextrose 50% over 3 minutes with the subject supine.
Includes blood draws and fasting requirements.

Hyperglycemia (rest controlled) will be induced by i.v.
injection of 25 mL of dextrose 50% over 3 minutes with the subject supine.
Blood will be sampled every 10 min from 0700 to 1300 h.
Each intervention will begin at 0800 h after 1 h of baseline sampling, and be completed by 0900 h.
Intervention is followed by 4 additional h of sampling to capture recovery (total sampling 6 h).
Ten-min samples are for Te, LH, ACTH, cortisol, and GH.
Glucose will be checked every 30 min.
At 07000 h an archival serum sample will be obtained for safety-monitoring purposes.
Beginning at 1900 h on the evening prior to each study visit, subjects will remain fasting except for water, diet soda, and other non-caloric and non-caffeinated fluids, until 1300 h the next day.

실험적: Exercise
Monitored exercise of 7-minute biking, 2-minute arm weights and a blood draw at the 10-minute time point will be repeated 3 times,which takes 30 minutes. Bilateral arm curls begin at 20 pounds and decrease by 5 pounds as needed to sustain 2 minutes of exercise at a rate of 1 complete curl every 2 seconds. Includes blood draws and fasting requirements. |
