Frailty and physical activity

Care, prevention and rehabilitation

Prevention and measures against frailty are important to prevent future conditions that require nursing care. In this laboratory, we are engaged in practical research that contributes to health promotion so that elderly people can continue to live their own lives. People with frailty or sarcopenia have reduced physical activity. We are investigating the adverse effects on health caused by this decrease in physical activity and the expected effects of improving it. It has become clear that maintaining an active lifestyle is important for preventing and dealing with frailty. As one method, we are verifying the health effects of quantitatively understanding one's own physical activity and taking steps to promote health.

A completely new system for dealing with frailty that does not assume the use of outpatient facilities

Quantitatively grasp the physical activity of the elderly and implement initiatives to promote their health.

To enable elderly people to continue living in their own way and prevent them from needing nursing care in the future
