Detection principle: water in the body is conductive, while fat is not. The fuzzy length is calculated by measuring the resistance and calculated according to the formula.

So what should I think of the physical test sheet?

In fact, only two data above are accurate: one is weight and the other is body mass index.

Some things are meaningless to measure once: skeletal muscle, body fat and percentage of body fat.

In addition, basal metabolism must be tested in an empty stomach, supine, awake and quiet state at room temperature of 20-25℃, otherwise it is useless.

So don't listen to the coach's cards just because of a physical test sheet. Some just want to make money.
