Why buy scales-analyzers and what indicators to pay attention to

Scales-analyzer – show how well you feel, for which several important indicators of the body are measured. We will talk about how and why this is done today.



All the metrics of smart scales-analyzers somehow record what helps you to lose weight or gain weight (depending on the purposes). Even when it comes to hydration, one must understand that this parameter is introduced for a reason. At the same time, having some degree of convention, they still help to track trends in time and with some, if only superficial, study of the issue, these trends will help to draw some conclusions.

Bioimpedansometry

The technology is based on bioimpedance analysis, known since the 1960s, based on the measurement of electrical resistance of tissues. Such an analysis is considered accurate and helps to identify a number of diseases and to assess the body composition of a person for compliance with accepted norms.

A clever balance is a kind of "truncated" bioimpedance analyzer, since there are very fewer leads here, as you know, – only in the heels, but this may be enough to calculate the basic parameters.

The main indicators of bioimpedanceometry

  • The level of water in the body
  • The level of fat mass
  • Analysis of bone tissue
  • Analysis of muscle mass

Also, in the process of bioimpedance analysis, the active cell mass, the rate of the basic metabolism and some other parameters can be calculated.

With the help of scales-analyzers, everything starts with weight, a parameter that does not require special explanations, and body mass index.

Where is biompedance analysis used

  • Endocrinology practice. The analysis allows to get an "objective picture" of the body composition and to reveal various deviations from the norm for subsequent correction with the help of exercise therapy, diets and other clinical measures.
  • Sports medicine. Diagnosis reflects trends that at the starting levels can not be seen in the mirror or feel. Also contributes to the adjustment of diets and training programs.

Clinical biomedance analysis, more detailed, also allows to assess the risk of various diseases of the musculoskeletal system, genitourinary system, diabetes (often – type II), as well as diseases associated with lack of protein in the body.

Also with the help of this study can be evaluated the viability of tissues during transplantation, etc.

Safety

It is not recommended to carry out bioimpedanceometry in pregnancy or having a pacemaker, and Also during menstruation, increased body temperature or skin damage in places of contact with electrodes.

Smart scales as a bioimpedance analyzer have wide capabilities today. We list the most important, central parameters on which to evaluate:

BMI

The body mass index is more a mathematics than an analysis. The simplest parameter, calculated by the formula: weight in kg / height in m ^ 2 .

That is, for example, 65 / (1, 709]

The level of fat

As already noted, any scales-analyzers are approximate figures in all data except weight, however These figures help track trends : if the percentage of fat will increase from metering to gauging, then this is a bad signal, and count on the fact that this "all lies" should not be.

You can calculate the percentage of fat and yourself: for this you need to divide the fat mass by the weight of the body, but for this you need to know the first parameter, which with accuracy will only give a hydrostatic weighing. The scales-analyzers do the calculation already "in the mind" – passing the current through one leg and receiving a signal with losses at the output – on the other leg – they divide the figure and give you the initial percentage, which then can decrease / increase depending on habits and image Life.

For men, it is seen that the range is from 6 to 13 percent – close to the athletic rate, over 25% – obesity.

Problems with determining the level of fat in the body would not be so acute if the excess of that would not be a possible factor in other, very sad diseases of the cardiovascular system, diabetes, etc., so even in this approximate form this percentage is very important And the claimed metric!

Bone mass

The most important parameter, which among others analyze the smart scales! The bone mass, or the mass of the mineral composition of the skeleton, is shown in kg and should correspond to the following norms:

Decrease is a bad sign, because, even guided by one's own logic, one should understand that Strength of bones = support and support of muscles and internal organs. With losses in this indicator in the trend, you need to see a doctor and make the proposed tests, because among other things, bone loss can indicate osteoporosis, a disease that is now on a par with oncology, diabetes and cardiovascular diseases.

Extract from statistics in the United States

Annually 1.5 million fractures associated with osteoporosis are fixed, of which 700 thousand vertebral fractures, 250 thousand hip fractures, 250 thousand fractures Fractures of the distal radius and 300 thousand fractures in other parts of the skeleton. The risk of fractures in the spine, femoral neck and distal radius is 40% for white women and 15% for white men aged 50 years and over. Up to 50% of patients with fracture of the femoral neck can not do without outside help, and 15 to 20% of patients die within 1 year. The number of osteoporotic fractures in the world is increasing and from 1.7 million in 1990 will increase to 6.3 million in 2050.

Hence

Also, more in-depth studies of bone tissue can identify specific types of cancer in children.

In any case, these data should not be underestimated.

Analysis of muscle mass

The increase in muscle mass is conditionally equated to a decrease in fat mass: more muscle – less fat, which is the main criterion when losing weight. However, this is not always the case.

The danger in some sense is low-calorie diets, which some use "in pairs" with physical exertion: there are few proteins in such diets, so losing weight – a person grows thin, but not by burning fat, but at the cost of both Once the loss of muscle mass!

In this connection, if the index of muscle mass, following the weight, decreases, then the trend can also be considered unfavorable, therefore it is customary to follow this with the help of improvised tools, including scales.

The muscle mass can be calculated independently:

Here is one of the advice

In order to determine the percentage of muscle weights in the human body, auxiliary devices are needed. Such are the caliper and the tailor's centimeter.

If the caliper is absent, then it can easily be replaced by a caliper. Before you start to determine the muscle mass in the human body, you need to be aware of what measurements of the body you need to take to begin with and take into account all sorts of nuances of this process.

Calculation begins with measurements using a centimeter, which you need to measure Four circles:

  • Shoulder
  • Forearm
  • Shin
  • The thigh

Measuring the shoulder is recommended only in a relaxed state, so strain the muscles during the measurement is not worth it. To try to measure the shoulder in the place where most of the muscles are located.

When taking measurements from the forearm, care should be taken so that the hand is not in tension and hangs freely.

With caviar, preferably in the place where they are identified most.

When measuring the thigh, it is necessary to become even, so that the body weight is evenly distributed on two legs. After that, the centimeter should be measured, covering the thigh under the gluteal fold.

After the required indicators were removed, further calculations will also require subcutaneous fat folds. The calipers will do this. On the basis of the data obtained, it is possible to calculate what kind of muscle mass a person has.

In order to calculate the muscle mass of a male body, one can use the Matejka formula. For this purpose, the following formula is developed: M = L * r2 * K

In order to understand the calculations, we can use the following decoding:

  • M – this Is the muscle mass of the body, which we need to calculate.
  • L – an indicator that characterizes the growth of men. For this formula, growth is recommended in centimeters.
  • r – Three steps are required to calculate this indicator. The first step is to calculate the sum of the four indicators obtained at the very beginning of the definition of mass: coverage of the shoulder, forearm, lower leg, and thigh. The resulting amount must be divided into 25, 12. The second action is similar to the first, because it also needs to know the sum of the indicators and divide it by 100. In the second step, measurements are taken of subcutaneous fat folds. The essence of the third action is to get the difference between the first action and the second. This difference is the exponent of r, which will need to be substituted into the formula, which was given above.
  • K is an unchanged indicator, which is equal to 6.5.

According to this formula, provided that the calculations were carried out, it is true that the muscle weight in the human body can be determined.

The norm of the muscle mass of the body in percent for Men and women are different. So, for a woman the norm is 35% of the total body weight. But the norm for a man is slightly higher and is about 43%.
Of course, with regular physical activity and proper nutrition in the athlete's body, the processes of increasing muscle mass are more active than in a person who has nothing to do with sports. Therefore, the norm for an athlete is 50% of the muscles of the total body weight.

Hence

It should also be taken into account that the balance is an unsegmented muscle mass, including both smooth and skeletal muscles, in other words, the average index, but with a uniform decrease in weight and muscle mass, one must guess that something has probably gone wrong, and

The level of fluid in the body

First of all, in the scales this metric is introduced because the decrease in the level of the liquid leads to a set of fat, in other words for those who Grows thin, it is important to track this. A liquid level of 50-75% is considered normal.

It should also be understood that water as a whole is assigned one of the key roles in our health. Here are just a few "spheres of influence":

  • body temperature adjustment
  • provision of nutrients, oxygen, enzymes, hormones
  • withdrawal of toxins and metabolic products from the body
  • supporting the normal operation of the joints
  • ensuring the natural moisture of the skin and other tissues, etc.

With a decrease in this indicator, it is necessary to consult a specialist, since a lack of water worsens the kidneys, increases the load on the liver, etc., which can lead to serious chronic diseases.

What scales to choose

Libra-analyzers are an extraordinary set, and each model claims to be accurate. Attention deserves the novelty that we brought recently – the MGB Body fat scale.

First, they offer the widest range of metrics that will give odds to most popular models, including Xiaomi. Secondly, the price – it is more than viable in this category and, finally, dimensions, which is important. But first things first.

Application

The scales are synchronized via Bluetooth with iOS and Android-devices, after which it is required to register.

At the moment we are busy translating the application, However, while the software is in English. Nevertheless, everything is pretty clear. The analysis is made on 13 metrics, among which are those that we have already described, and others:

  • Muscle mass in percent and kg
  • Hydration
  • Bone mass
  • BMR – metabolic rate. This menu shows the calorie prediction needed to maintain the body at rest. This index is "sensitive" to the lifestyle, for example, when gaining muscle mass, the indicator will grow.
  • The level of visceral fat is an important indicator. Conditionally visceral fat – it's like, on the one hand, a pillow for the internal organs, on the other – something like a "warmer" for them. A high level of visceral fat raises pressure, provokes heart disease, reduces sensitivity to insulin, which can cause diabetes. Data are offered in units of:

  • The fat-free mass
  • Protein

The data is immediately loaded onto the main screen: the key parameters are the weight, the body mass index, the fat mass, and then the list goes further.

For each metric, one can get the decryption, however,

The application supports the "multi-user" mode.

Appearance

The scale has, you can say, a classic look: a white square with a display in the middle at the top. The distinctive feature of this model is the small size: the square 26X26 is only 2.5 cm away from the floor

It is separated, by the way, on rubberized, firm legs, that is, they will not go anywhere in the tile.

There are scales from 4 "little fingers" batteries:

Sold device in a thin, nebulous box, on the back side Which can be found links to both applications, as well as enumeration of the data obtained:

The price of the device

Now the price / quality / Consumer accuracy they look very good: at retail this model costs 2490 rubles, which with such a set of characteristics seems profitable.

Also, when paying on the site, you can Use This Criterion special coupon: MGBBFS . In this case, the scales will cost 1990 rubles.
