상세 설명
A 6-month, single blind, randomized, controlled multi-center clinical trial comparing a Health Education control intervention to a supervised Progressive Resistance Training intervention to test the central hypothesis that biological mechanisms of aging are mediators of exercise response heterogeneity in older adults.

측정값 설명 |
기간 |
|---|---|---|
|
Precisely define the variability in changes in physical function
기간: baseline, 6 months
|
Measured by the Short Physical Performance Battery (SPPB), a 0-12 categorical scale of walking speed, standing balance, and repeated sit-to-stand time, with higher scores reflecting better physical function. |
baseline, 6 months
|
|
Precisely define the variability in changes in blood glucose concentrations in response to a meal tolerance test
기간: baseline, 6 months
|
Blood glucose concentrations (millimoles/liter) will be measured in response to a physiologically relevant meal challenge. Lower values are indicative of better metabolic health. |
baseline, 6 months

기간 |
|---|---|---|
|
Precisely define the variability in changes in skeletal muscle size.
기간: baseline, 6 months
|
Measured by computed tomography scans of the mid-thigh. Larger muscle cross-sectional area (cm^2) reflects a greater quantity of skeletal muscle. |
baseline, 6 months
|
|
Precisely define the variability in changes in skeletal muscle strength.
기간: baseline, 6 months
|
Measured by the one-repetition maximum, in newtons, on a leg press device, with higher scores reflecting greater skeletal muscle strength. |
baseline, 6 months
|
|
Precisely define the variability in changes in six-minute walk distance.
기간: baseline, 6 months
|
Measured by the distance (meters) walked in six minutes, with longer distances reflecting better physical function. |
baseline, 6 months
|
|
Precisely define the variability in insulin secretion in response to a mixed meal tolerance test.
기간: baseline, 6 months
|
Blood insulin concentrations (pmol/L) will be measured in response to a physiologically relevant meal challenge. Insulin concentrations in a physiological range reflect better metabolic health, while low insulin concentrations can reflect an impaired insulin response and high insulin concentrations can reflect peripheral insulin resistance. |
baseline, 6 months
|
|
Precisely define the variability in changes in the percentage of glycated hemoglobin in the blood.
기간: baseline, 6 months
|
Measured by the percentage of glycated hemoglobin in the blood (often referred to as HbA1c). A lower percentage of HbAlc reflects lower blood glucose concentrations over the past two to three months. |
baseline, 6 months
|
|
Precisely define the variability in changes in blood lipids.
기간: baseline, 6 months
|
Blood lipids, including total cholesterol, low density lipoproteins (LDLs), high density lipoproteins (HDLs), and triglycerides will be measured. Lower levels of total cholesterol (mg/dL), LDLs (mg/dL), and triglycerides (mg/dL), and higher levels of HDLs (mg/dL), are reflective of better metabolic health. |
baseline, 6 months
|
|
Precisely define the variability in changes in waist-to-hip ratio.
기간: baseline, 6 months
|
The circumference (cm) of the waist and hips will be measured and a ratio will be calculated. A lower waist-to-hip ratio is reflective of a better body composition (less central obesity or visceral fat). |
baseline, 6 months
