Not by chance I want to indicate it with BIVA and not simply BIA, as often bioimpedance is reported.
The extra V stands for vector, what does it mean?
Bioimpedance is based on the passage of a weak electric current through the body, the various ones compartments behave differently, they can be insulators, conductors or capacitors (ie they hold the current and then let it pass after a certain time, the cells do behave in this way).

There are now many devices of this kind, but only those that return two vectors they are more reliable.

It should be emphasized that bioimpedance first reads body water then from this reading through complex algorithms (often even these make the difference in the goodness of reading e then of the instrument) they calculate the other parameters, which are:

  • Total hydration: it is the quantity of body water, essential for any purpose make it possible to reach a dehydrated organism that does not "work" at its best; if we talk about athletes it is decisive, just think that losing 2% of body water means worsening one's own 25% performance
  • Intra and extra cellular water: it is not enough for our body to be hydrated, but that water must being inside the cells, otherwise it is even harmful, certainly unsightly, is called e feared, especially by women, water retention.
  • Active cell mass (ATM or BCM): in practice from an estimate of the volume of our cells, that is, of the number but also of how much they are full of water (to remember that the water must stay inside the cells), can be seen as an index of real health, in an athlete as an index of state of form.
  • Phase angle: is the angle formed by the two bioelectric vectors, also represents an index of health and more about physical performance.
  • Fat mass percentage: it is the ratio between fat mass and lean mass, to be emphasized as you don't have to run into the error of seeing the index only on the fat side, you can have one high fat percentage also due to lack of lean mass, which often happens in a consequence of too restrictive diets or training that is too intense and not well compensated.
