Estudio comparativo de ecuaciones de predicción del porcentaje graso en varones de 8-11 años de edad

Abstract

The present study has an objective to compare for prediction equations that are goog to calculate the fatty percentage (% F) of a school population understood between the 8 and 11 years of age of sex masculine, the fellows they present an age average of 9.77±1.12 years, being on the other hand its corporalweight of 29.24±3.80kg and size of 131.84±6.56cm. Ontheotherhand, was select by strata 150 males probabilistically , being evaluated the corporal weight, height, and the cutaneous pleats triceps and subscapular. The data wer processed by means of the statistical analysis ANOVA and the multiple corrlation analysis, where the results shows the existence of (Parizkova and Roth, 1972) 17.86±3.92 VS (Boileau and col., 1985) 15.80:1:4.43, (Parizkova and Roth, 1972) 17.86±3.92 VS (Slaughter, 1990) 16.39±4.45 and (Parizkova and Roth, 1972) 17.86±3.92 VS (Cossio, et.al., 1999) 15.80±4.32. Likewise, among the techniques of (Slaughter, 1990) 16.39±4.45 VS (Boileau and col., 1985) 15.80±4.43 and (Cossio, et.al., 1999) 15.80±4.32, there were not a statistically significant differences; on the other hand, it was obtained high correlation values among the techniques of (Boileau and col., 1985) and (Cossio, et.al., 1999) r=0.975. Therefore the result are the most suitable for the analysis of (% F) of the present study, presenting likeness and similarity as for their statistical and populational distribution.
