Change in the number of chair stands during the 30-second chair stand test |
Physical performance will be objectively measured using the 30-second chair stand test, measured by the number of times a person comes to a full standing position from a chair in 30 seconds. Scores range from zero (cannot perform the test) to 30 or higher, with a higher number of chair stands representing stronger leg strength. |

Change in balance score during the 4-stage balance test. |
Physical performance will be objectively measured using the 4-stage balance test. The 4-stage balance test includes standing in each of four positions for up to 10 seconds: 1) feet side-by-side; 2) semi-tandem stand [one foot slightly behind but touching the other foot]; 3) tandem stand [one foot in front of the other; heal touching toe]; and 4) stand on one foot. Scores range from zero (cannot perform the test) to 40 (completion of all four positions). Higher scores represent better balance. |

Change in number of steps per day |
The activPAL accelerometer/inclinometer will be used to measure steps per day. Participants will be asked to wear the monitor for 7-days. Average daily steps will be calculated as the total steps divided by the number of days the monitor was worn. |

Change in objective measures of light-intensity physical activity |
The activPAL accelerometer/inclinometer will measure the daily minutes spent in light-intensity stepping. The average daily minutes of light-intensity stepping will be the total minutes divided by the number of days the activPAL monitor was worn. Light-intensity stepping is defined as stepping at a cadence equivalent to 1.5 to 3.0 METs. A MET is a multiple of resting energy expenditures. With resting (sitting quietly) energy expenditure defined as 1 MET, a 3-MET activity expends the energy of rest by 3 times. |
