Study IDST000641
Study TitleTargeted Amino Acids in American Indian Adolescents (part II)
Study SummaryThe goal of this study is to determine the effect of physical activity on the blood concentrations of several compounds that are proposed to be markers of diabetic risk. We will compare results from normal weight and obese American Indian adolescents, with high or low habitual physical activity. We will also compare the same blood markers in the obese group before and after 4 months of exercise to measure the benefit of the program.

Sample Preparation:

Sampleprep ID:SP000671
Sampleprep Summary:Part 1: Longer-term exercise training study: Samples #1-133. Overweight/Obese adolescents (IDs 434-001 through 434-132) enrolled into a 48-week exercise program (3 days per week). Samples submitted are from the pre-training (Baseline) and the end of the first 16 weeks (Post-training) times. Compliance with the exercise program varies widely among participants. An additional set of normal weight reference group adolescents (IDs 434-301 through 434-308) are included. Note that 15 OW/OB participants in the exercise group and all 8 NW reference group participants have only a single baseline sample. All samples were collected following overnight fast into EDTA (lavender top) glass tubes for preparation of plasma, kept on ice 20 minutes, spun, aliquoted and then kept frozen. None have been previously used. Part 2: Short-term exercise training study: Samples with ID 11xxx. Overweight/Obese adolescents completed a short-term exercise program, consisting of 10 sessions over 5 weeks. Samples were collected following overnight fast, before (Baseline) and after (Post-training) the training program. These samples are serum since plasma was used for other analyses. All tubes are marked with a unique ID number (shown in list below) in black marker. Additional sample details on the labels are listed in the accompanying Excel spreadsheet.
