Aging is said to start in the legs, and the decline in walking speed begins in the 40s or 50s. This walking speed refers to a walking speed that is easy to walk in daily life, that is, normal walking speed or preferred walking speed, usual walking speed.
The relationship between normal walking speed and health has already been validated in many academic papers.

Walking is an exercise in which many musculoskeletal systems are coordinated with time lags, so it is necessary to maintain and control the balance of the whole body as well as the strength of the leg muscles. As we age, this control becomes less smooth, and our gait begins to become erratic and slow down. It's not just physical strength and strength.
Decrease in normal walking speed is generally very gradual. Therefore, it is necessary to reliably detect slight changes in order to detect signs of a downward trend at an early stage, to steadily detect a slight recovery and gain confidence, and to maintain the desire to recover for a long time. . If you can't detect the symptoms early on, even if you notice it after your body has weakened, your physical strength is already declining, so you won't be able to do enough exercise to recover, and recovery will tend to be too late.
However, the existing speed measurement method (app) cannot even determine whether the measured value of minus 2% is actually less than minus 5% or more than plus 1%. It was not possible to assess recovery.
The app reliably detects small changes in normal walking speed based on newly discovered phenomena.
The app detects all your steps during the day. Therefore, by analyzing the large amount of walking data, we can capture the normal walking speed and its slight changes.
Walking speed decreases gradually over the years. However, if we do not know the normal walking speed before the speed slows down, we cannot detect the change compared to when it slows down slightly.
Therefore, ideally, you should start using it around the age of 40, when it should not have slowed down yet, and continue using it for many years.
People in their 40s still have physical strength and may not feel the need for it. However, there is also an academic paper that the walking speed of people in their 40s greatly affects their health in the prime of life and old age.
Please use this app regularly and keep your health and youth for a long time.
