Descrição
Inclusion Criteria:
All subjects must meet the following eligibility criteria:
- Age range: 60 years and older
- Body mass index between 20-29 kg/m2
- Weight stable (< 2 kg weight change within last 6 months)
- Non-smoking
- Constant habitual activity patterns within last 3 months
- Clinically normal blood profiles (specifically, normal liver and kidney function; normal complete blood count (non-anemic); fasting blood glucose <110 mg/dl)
- Not taking medications known to influence appetite or metabolism
- Non-diabetic
- Confirmation of acceptability of eating the study test foods (solids and fluids)
Trained subjects (Recruiting 36; N-25) must meet the following eligibility criteria:
- Resistive exercise training (≥ 2 times a week) based on reported physical activity levels (questionnaire)
- Active fitness level (≥ 2, 30-minute aerobic exercise sessions/week)
Sedentary subjects (Recruiting 36; N-25) must meet the following eligibility criteria:
- Resistive exercise training (≤ 1 time a week) based on reported physical activity levels (questionnaire)
- Active fitness level (≤ 2, 30-minute aerobic exercise sessions/week)
Exclusion Criteria:
All subjects will be excluded based on the following exclusionary criteria:
- Age: <60 years
- Body mass index: outside of the 20-29 kg/m2 range
- Gained or lost > 4.5 kg within the last 6 months
- Smoker (currently or within the last year)
- Intermittently been involved in a diet and/or exercise program within the last 3 months
- Clinically abnormal blood profiles as identified by our study physician, Arthur Rosen, MD
- Taking medications (currently or within the last 3 months) known to influence appetite or metabolism
- Abnormal heart function (interpreted by a cardiologist) and assessed (for study exclusion) by our study physician, Arthur Rosen, MD
- Clinically diagnosed as diabetic
- Study foods are found to be unacceptable for consumption by the subject
- Clinically diagnosed osteoporosis
Trained subjects will be excluded based on the following exclusionary criteria:
- Did not perform resistive exercise training (currently or within the last 3 months) based on reported physical activity levels (questionnaire)
- Perform ≤ 1, 30-minute aerobic exercise session/week (currently or within the last 3 months) based on physical activity levels questionnaire)
Sedentary subjects will be excluded based on the following exclusionary criteria:
- Performed resistive exercise training (currently or within the last 3 months) based on reported physical activity levels (questionnaire)
- Perform > 2, 30-minute aerobic exercise sessions/week (currently or within the last 3 months) based on physical activity levels questionnaire)
