The present invention relates to a frailty degree monitoring system and a pedometer.

There have been many papers and articles on walking speed and health, and it is known that walking speed and stride value are important indicators for health. It is also known that as the elderly age, the decrease in muscle mass of the upper and lower limbs known as sarcopenia causes a decrease in walking speed and a decrease in stride value, which tends to lead to a frail state. For this reason, a health management technique that monitors daily walking speed and stride value and leads to prevention of frailty is disclosed, instead of the conventional health management that aims at the number of steps.

For example, the following patent documents include a pedometer that can accurately measure walking speed and walking distance by accurately grasping the stride value that changes depending on the walking method, and can enhance the exercise effect and effectively improve the physical ability. It is disclosed in 1.

The prior art disclosed in Patent Document 1 calculates walking speed and stride value from an acceleration signal of the lower limbs and personal data input means, and further outputs walking force evaluation data at a plurality of stages based on the walking speed and stride value. It is configured to be equipped with walking ability evaluation means.
