描述
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.

Changes in insulin sensitivity following the exercise intervention as estimated with the QUICKI algorithm (quantitative insulin sensitivity check index)
大体时间：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.
