“Preferred Speed” automatically measures the preferred walking speed that your body remembers. Early detection of changes and early treatment can help you maintain your youth for a long time.
The academic paper has been published that clarifies the basis for this.
（“Preferred walking speed”）
- Many academic papers shows that walking speed is closely related to health and serious diseases. For instance, slow walking speed is more likely to cause dementia. This walking speed is the “preferred walking speed” that everyone has and unconsciously walks at this speed frequently in daily life.
- The preferred walking speed decreases from about 5km/hour (120 steps/minute) when you are in your 40s to about 3km/hour (100 steps/minute) as you age and become frail. During this time, the stride length becomes narrower in proportion to the number of steps per minute (cadence).
- However, after pre-frail or frail, the cadence (the number of steps per minute) does not change much, and the stride will shorten and walking speed begin to slow down.
（You can now measure your“Preferred walking speed”!）
- Even if you try to measure the “preferred walking speed” with a measuring device, it is impossible. Because when you are conscious of the measurement, the way you walk changes, and in many cases, you end up walking faster.
- The key of health indicators is that they can read “changes” in health status. If you are alerted to changes in the early stages, you can take an action before it is too late. If you can see a slight improvement, you will feel more confident and can continue your recovery efforts.
- However, When the speed decreases by 30% over several decades, overlooking a slight change of about 3% will not be useful as an indicator. In order not to overlook this slight change, the measurement accuracy must be well below 1% error. Otherwise, you run the high risk of obtaining erroneous results, such as the ratio remaining the same even though it is on the decline, or decreasing slowly when it is slowly recovering.
- With other measurement apps, the error was so large that it was impossible to read the “slightest change”. Because the error rate of conventional measurement methods was significantly higher than 1%, and the reliability of measurement results was extremely low.
- The “Preferred Speed” is the first and only one in the world to accurately measure these changes!
（How to install and use the app）
- iPhone version: search for “Preferred Speed” at App Store
- Available for free. Opening the app, your preferred speed for the last five days will be automatically measured and displayed in a graph.
- And opening the app, the number of steps you have taken up to that time will be displayed immediately, so you can use it every day as a pedometer.
- The “preferred walking speed” decreases over the years, so please use it continuously for at least 3 years, and stay young for a long time by using it in a variety of ways, such as checking your recovery in the fall from summer fatigue, checking the effects of a healthy walking style, and checking the speed of your fast walking exercise habits.
- Learning how to walk using your core will increase your stride length and speed, which is also beneficial for your health. Let’s learn this from your 50s and 60s! You can evaluate the effectiveness of your method with this app.
