La description
Inclusion Criteria:
Adult, ambulatory males > 60 years old (n=30) will be recruited for this proposed study. Participant inclusion criteria also includes having clinically significant sarcopenia based on the body composition assessment showing an aLM that is < 2 SD below the mean values of a young adult reference group using DEXA scanning.
Exclusion Criteria:
Exclusion criteria include BMI scores > 30 or a Mini-Mental Status exam score of < 22. The second tier of screening will include the following blood tests, obtained between 8-9 AM, following a 12-hour overnight fast: CBC, routine chemistry profile (e.g., glucose, kidney and liver function tests). Veterans with an elevated fasting blood glucose by WHO criteria (FBG >110 mg/dl), triglyceride levels > 200 mg/dL, and/or known DM, or abnormalities of other routine blood tests (i.e., > 2 SD beyond normal) will be excluded from the study. Uncontrolled cardiovascular disease, non-ambulatory status, evidence of a major disease exacerbation over the last six months, and current participation in a supervised exercise program (minimum of three months, twice per week) would also preclude participation in this study.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Changes in insulin sensitivity following the exercise intervention as estimated with the QUICKI algorithm (quantitative insulin sensitivity check index)
Délai: Change from baseline in QUICKI values at week 6, week 12, and week 24
|
Blood tests will be obtained after a 12- hour overnight fast at baseline, weeks 6, week 12 and week 24: glucose and insulin values will be determined before and during a standard (75 g) 2 hour oral glucose tolerance test (to determine insulin sensitivity via QUICKI algorithm.
