In detail, we will look for a "possible correlation between its theoretical principles and the results - in terms of body composition - concretely obtainable in the field, estimating them by means of the now known bioimpedance analysis (BIA).
by Mike Mentzer, also BIIO is based on the awareness that an excessive training load due to too high volumes is, more often than not, limiting and even counterproductive.The theoretical principles of BIIO are contained in its acronym: B.reve, Intense, Infrequent, Organized.
But how to actually evaluate a possible plateau or regression - in terms of the cross section of the muscle - due to this common programming error?
Thanks to anthropometric measurements and body composition estimation equations.
, of the muscular circumferences and of the adipose folds (plicometry), today the use of bio-impedancemetry (BIA) is particularly widespread.Born with the aim of calculating the state of body hydration, today the BIA is able to estimate the intra and extra cellular distribution of liquids, as well as the extent of lean and fat mass (in clinical, aesthetic and sports ), cell mass (BCM), basal metabolic rate (BMR) etc.
However, bio-impedancemetry, like plicometry, is also an indirect evaluation method. Extremely simplifying, we could say that:
its operation is based on the induction and subsequent reception of an imperceptible electrical stimulus, from one end of the organism to the other. By measuring the difference in this current, and inserting the data into special algorithms, the BIA then obtains all the parameters of the case.
On the other hand, bio-impedancemetry also presents a certain "margin" of error. Paradoxically, the hydration status of the subject constitutes the factor mainly limited to a correct estimate of the general body composition.
and require, in addition to drinking more, often the integration with mineral salts. This is because a dehydrated body, in addition to not being healthy, shows lower athletic performance.
Secondly, some argue that excessive exercise volumes may be responsible for a greater accumulation of extracellular fluids. In fact, high volumes of training certainly cause a more transient state of inflammation than shorter sessions; on balance, there is a slight increase in subcutaneous swelling, which however vanishes within a few minutes.
BIIO and body cell mass
The body cell mass - cell mass (BCM) - represents the totality of living metabolically active cells.
Muscle mass is the main constituent of BCM, therefore, by analyzing the latter we could easily estimate the effectiveness of training. If BCM remains unchanged or worse it tends to decrease, training is undoubtedly inadequate.
There are those who maintain that, in the BIA analysis, by reducing the number of workouts to a maximum of 2 per week, with the lowest volume and maximum intensity per session, an increase in cell mass can be found.
BIIO and body cell mass index
The body cell mass index (BCMI) is the relationship between the BCM and the height of the subject; it provides us with more sensitive information than a possible malnutrition.
Downward variations of this index make us understand that the subject has an insufficient caloric intake, or consumes an inadequate amount of protein or carbohydrates for the situation.
By observing this value, in correspondence with the weight and the percentage of fat mass, it is possible to manage the dietary parameters by monitoring the impact of any changes.
