Body composition analyzers and their credibility | safe-sport
With the long-awaited spring, gyms and fitness clubs are inundated with new customers fighting for show silhouette worthy bikini in the upcoming season. Tony poured sweat, or subjective feelings of better appearance, are often not sufficiently measured, the results of our work. Hence the search for the most objective ways to measure and indicator that directly tell us whether you work in the gym brings results.
Suggesting the results of the basic measurement of body weight on the proverbial 'bathroom scale' can be frustrating. Not everyone realizes a scale that, very often, along with the reduction of body fat is going to increase muscle mass. Measurement of body weight may therefore give the opposite result - instead of reducing the number of pounds a scale of nuggets us nightmares, you will increase a scale them. What's more, there are situations that body weight decreases, but fat mass grows because of poor hydration or mismatched a scale diets. Therefore, in the home can supplement measurements of body weight measurement circuits. Buying tailor's tape costs about 5 zł, and certainly many of you save the stress associated with the lack of effects on weight.
Another popular indicator used to define underweight, normal, overweight or obesity is the body mass index called BMI (Body Mass Index). It is produced by dividing the weight in kilograms by the square of height in meters given. Unfortunately also this indicator does not specify the relationship of body fat to muscle mass and those with high physical activity may indicate overweight. Therefore, it was necessary to analyze the composition of the body, or its individual components, such as water, fat, muscle, or bone tissue in relation to each other. Hence the idea to use electrical resistance of body tissues ie. impedance. During the measurement of special devices through the body is transmitted electrical signal of very low intensity, completely undetectable. The electrical resistance of individual tissues is different. Muscle tissue is composed of about 80% water and electrolytes which is a very good conductor, as compared to fat tissue, which consists of only 20% of the water. It is a noninvasive, safe and painless, but people with pacemakers or pregnant women should not join the study.
Are these indicators a scale are reliable? To answer this question would need to determine the accuracy, precision and repeatability of the measurement device. On the market there are outfits that advertise as body composition analyzers within the price from 70 zł to even 7000 zł. To select the appropriate equipment, ask yourself how much you need advanced a scale information for themselves. Available analyzing bathroom scales and body composition will be characterized by the smallest measurement precision due to poor discrimination of fluid contained in the body. What's more important here is the individual thickness of the skin on the feet. This does not mean, however, that measurement is entirely worthless. It allows you to more or less get an idea of the composition of the body, and how it changes when changes in diet, exercise, or other external factors. However, to assume the appearance a scale of considerable differences compared to a professional test. Greater accuracy of bathroom scales are characterized by equipment with additional handles a scale on the upper limbs. Thanks to them, we are sure that the measurement is also collected from the upper part of the body, which is important for people with muscular legs construction and construction filigree rim of the upper limbs, or vice versa - skinny a scale legs and massive shoulders and back. Most professional equipment can be found in institutions dietary or better fitness a scale clubs. Increased number of electrodes and analyzing measurements of body segments insures greater accuracy.
You should also remember to do measurements at the same time of day 3-4h before a meal, or preferably in the morning on an empty stomach. Before the measurement, avoid drinks moczopennych, avoid consuming alcohol for 24 h before measurement, clean the skin thoroughly hands and feet before measurement. Analysis a scale of body composition will better diet plan and carry out the appropriate sports training a scale depending on your fitness goals. I recommend!
Zuza forgot to write about one important a scale issue - the repeatability of measurements. Ie. first we can get the result of very different from measurement of the other. This is due to surges of water the order of 1-5kg per day (!) Which has a fundamental impact on the result. a scale Whether a measure is comparable, tells us impedance, or resistance in ohms, which puts our body. If the two measurements are similar to each other impedance (standard deviation of ~ 5 ohms), then we believe that in our flesh there was a change. For larger deviations difference in the estimated proportion of the machine t
