O principal objetivo da avaliação da composição corporal recai sobre a determinação do percentual de gordura. Dentre os vários métodos possíveis, o que envolve a mensuração de dobras cutâneas pode ser bastante acurado - se bem escolhidas as equações a serem utilizadas. Neste aplicativo foram inseridas as seguintes equações:
Jackson & Pollock (1978) p/ homens brancos, 18 a 61 anos, pregas: peito, abdôme e coxa:
Dc (g/cm³)=1,109380-0,0008267(∑3DC)+0,0000016(∑3DC)²-0,0002574(idade)
Jackson, Pollock & Ward (1980) p/ mulheres brancas, 18 a 55 anos, pregas: coxa, tríceps e suprailíaca:
Dc (g/cm³)=1,0994921-0,0009929(∑3DC)+0,0000023(∑3DC)²-0,0001392(idade)
Jackson & Pollock (1978) p/ homens negros, 18 a 61 anos, pregas: peito, abdôme, coxa, tríceps, subescapular, suprailíaca e axilar média:
Dc (g/cm³)=1,1120-0,00043499(∑7DC)+0,00000055(∑7DC)²-0,00028826(idade)
Jackson, Pollock & Ward (1980) p/ mulheres negras, 18 a 55 anos, pregas: peito, abdôme, coxa, tríceps, subescapular, suprailíaca e axilar média:
Dc (g/cm³)=1,0970-0,00046971(∑7DC)+0,00000056(∑7DC)²-0,00012828(idade)
Siri (1956, 1961):
%G=[(4,95/Dc)-4,50]x100
Heyward (2001):
%G=[(5,01/Dc)-4,57]x100, %G=[(4,85/Dc)-4,39]x100
Heyward & Stolarczyk (1996):
%G=[(4,37/Dc)-3,93]x100
Lohman (1986):
%G homens – 7 a 8 anos: [(5,38/Dc)-4,97]x100, 9 a 10 anos: [(5,30/Dc)-4,89]x100, 11 a 12 anos: [(5,23/Dc)-4,81]x100, 13 a 14 anos: [(5,07/Dc)-4,64x100], 15 a 16 anos: [(5,03/Dc)-4,59]x100, 17 a 19 anos: [(4,98/Dc)-4,53]x100, 20 a 50 anos: [(4,95/Dc)-4,50]x100
%G mulheres – 7 a 8 anos: [(5,43/Dc)-5,03]x100, 9 a 10 anos: [(5,35/Dc)-4,95]x100, 11 a 12 anos: [(5,25/Dc)-4,84]x100, 13 a 14 anos: [(5,12/Dc)-4,69]x100, 15 a 16 anos: [(5,07/Dc)-4,64]x100, 17 a 19 anos: [(5,05/Dc)-4,62]x100, 20 a 50 anos: [(5,03/Dc)-4,59]x100
A principal ideia em se disponibilizar este aplicativo para os celulares Android é a de facilitar a obtenção das massas gorda e livre de gordura por parte dos interessados - que, além da praticidade, podem minimizar a chance de possíveis erros ao se calcular tudo "na mão" (principalmente quando o número de avaliados em uma mesma oportunidade for grande).
É válido ressaltar a grande importância em se realizar medidas fidedignas - pois, tudo decorre das mesmas (ou seja, se a medida não for bem feita, tudo o que vier depois, como já dizia um de meus grandes professores, não será bom...).
Associado à inteligência, este aplicativo pode colaborar sobremaneira em um processo avaliativo pertinente à rotina dos profissionais de Educação Física.
The main objective of body composition evaluation is to determine the percentage of fat. Among the several possible methods, what involves the measurement of skin folds can be quite accurate - if well chosen the equations to be used. In this application the following equations were inserted:
Jackson & Pollock (1978) for white men, 18 to 61 years, folds: chest, abdomen and thigh:
Dc (g / cm 3) = 1.109380-0.0008267 (Σ3DC) +0.0000016 (Σ3DC) ²-0.0002574 (age)
Jackson, Pollock & Ward (1980) for white women, 18 to 55 years, folds: thigh, triceps and suprailiac:
Dc (g / cm 3) = 1.0994921-0.0009929 (Σ3DC) +0.0000023 (Σ3DC) ²-0.0001392 (age)
Jackson & Pollock (1978) for black men, 18 to 61 years, folds: chest, abdomen, thigh, triceps, subscapular, suprailiac and mid axillary:
Dc (g / cm 3) = 1.1120-0.00043499 (Σ7DC) +0.00000055 (Σ7DC) ²-0.00028826 (age)
Jackson, Pollock & Ward (1980) for black women, 18 to 55 years, folds: chest, abdomen, thigh, triceps, subscapular, suprailiac and mid axillary:
Dc (g / cm 3) = 1.0970-0.00046971 (Σ7DC) +0.00000056 (Σ7DC) ²-0.00012828 (age)
Siri (1956, 1961):
% G = [(4.95 / Dc) -4.50] x100
Heyward (2001):
% G = [(5.01 / Dc) -4.57] x100,% G = [(4.85 / Dc) -4.39] x100
Heyward & Stolarczyk (1996):
% G = [(4.37 / Dc) -3.93] x 100
Lohman (1986):
% G men - 7 to 8 years: [(5.38 / Dc) -4.97] x100, 9 to 10 years: [(5.30 / Dc) -4.89] x100, 11 to 12 years: (5.23 / Dc) -4.81] x100, 13 to 14 years: [(5.07 / Dc) -4.64x100], 15 to 16 years: [(5.03 / Dc) -4.59 ] x100, 17 to 19 years old: [(4.98 / Dc) -4.53] x100, 20 to 50 years old: [(4.95 / Dc) -4.50] x100
% G women - 7 to 8 years: [(5.43 / Dc) -5.03] x100, 9 to 10 years: [(5.35 / Dc) -4.95] x100, 11 to 12 years: (5.25 / Dc) -4.84] x100, 13 to 14 years: [(5.12 / Dc) -4.69] x100, 15 to 16 years: 64] x100, 17 to 19 years: [(5.05 / Dc) -4.62] x100, 20 to 50 years: [(5.03 / Dc) -4.59] x100
The main idea in making this application available for Android phones is to make it easier for consumers to get fat and fat-free masses - which, in addition to practicality, can minimize the chance of possible errors when calculating everything "in the hand "(especially when the number of evaluated at the same opportunity is large).
It is worth noting the great importance of taking reliable measures - because everything comes from them (that is, if the measure is not well done, everything that comes later, as one of my great teachers already said, will not be good .. .).
Associated with intelligence, this application can collaborate greatly in an evaluation process pertinent to the routine of Physical Education professionals.
