What are "Mets" and "Mets Time"?

This is the "physical activity" that indicates "how many times more energy is consumed compared to when resting (the state of lying down and making it easier) is set to 1."

It represents "physical activity amount" and can be expressed by the following calculation.
　　　 Exercise intensity "Mets" x Implementation time (Time)

For example, if you perform exercise intensity activity for 3 Mets for 1 hour, you can calculate the amount of physical activity using the following calculation.
　　　 3 Mets x 1 hour = 3 Mets ・ Physical activity at times

By the way, the exercise intensity of 3 Mets include "normal walking (about walking a dog)", "riding a bicycle with electric assist", and "helping the kitchen".

In addition, calorie consumption (kcal) is calculated by the following formula.
　Physical activity ("Mets & Time") x weight (Kg) x 1.05

3 It is said that it is good to perform "physical activity" of Mets or more in one week 23 Mets.
Simple calculation requires about 3.3 Mets / hour physical activity per day.
3 The amount of physical activity at Mets and time is almost the same as "normal walking (about dog walking) 60 minutes".
