Frailty refers to the decline in the physiological reserve or multi-system functions in the elderly. Adverse events in them such as upper respiratory infection, minimally invasive therapy and shift to new medication may lead to functional decline, reduced self-care ability, and shortened life expectancy. Studies have found that early intervention can be expected to reverse frailty, with exercise in particular showing a clear effect on alleviating frailty. This review aims to summarize the rescent research of exercise intervention for the elderly both in China and other countries in recent years with a view to providing scientific evidence for exercise intervention suitable for Chinese elderly with frailty.
