Eligibility Criteria

Age55 Years - 79 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Ability to provide informed consent
  • Ability to perform motor and cognitive tests (e.g., can rise from a chair, walk for 2 min, climb 10 stairs)
  • Women will be confirmed as postmenopausal (either natural or surgical) based on cessation of menses for \>1 year.

You may not qualify if:

  • ages \<55 years or ≥80 years
  • body mass index (BMI) \>40 kg/m2 (rationale: vascular function and blood pressure measurements can be inaccurate in severely obese subjects and these subjects may differ in many ways from normal weight, overweight or less obese subjects)
  • not weight stable in the prior 3 months (\>2 kg weight change) or unwilling to remain weight stable throughout study (rationale: recent weight change or weight loss can influence vascular function)
  • having unstable angina, acute myocardial infarction, coronary angioplasty, or aorto-coronary bypass surgery as defined by the occurrence of an event, symptom, surgery, or change in medication and/or dosage within 3 months prior to enrollment
  • having thyroid disease that is not controlled by medications or \<3 month's use of a particular medication and/or dosage (rationale: uncontrolled thyroid diseases are associated with alterations in vascular function)
  • having past or present alcohol dependence or abuse, as defined by the American Psychiatry Association, Diagnostic and Statistical Manual of Mental Disorders
  • abnormal blood chemistries for renal and liver function (\>1 standard deviation outside the normal range)
  • Moderate or severe peripheral artery disease (ankle-brachial index \<0.7).
  • Insufficient health to participate in a VO2max test based on a physical examination and/or graded exercise test (this will be determined in accordance with stated contraindications for exercise testing provided by the American Heart Association).
