Due to COVID-19 safety precautions and public health guidelines, the study was terminated early.

The purpose of this study is to evaluate a physical therapist (PT) led gait training intervention for 100 older adults with pre-frailty or frailty. The goals of this study are To determine the effect of gait training intensity on frailty, mobility, physical functioning, and quality of life, as well as balance and healthcare utilization.

Frailty is a leading cause of dependency among older adults, affects up to 60% of older adults, and is associated with an increased risk for falls, hospitalizations, institutionalization, and death. Exercise is the most widely recommended treatment for improving physical function among the frailty, but the optimal type or intensity of exercise is unknown. Walking is a preferred physical activity among older adults, however, there are no clear guidelines on the best intensity of walking to reduce frailty. The specific goal of this project is to compare a high intensity walking (HIW) intervention (70-80% of heart rate maximum) to a moderate intensity walking (MIW) intervention (50-60% of heart rate maximum) for pre-frail or frail older adults to determine the impact on frailty, mobility, balance, quality of life, and healthcare utilization.
