The aim of this research focus on knowledge of the muscular asymmetries in the upper and lower limbs in school aged children. Sample: 144 children (73 girls and 71 boys) registered on the 1th grade (n = 60) and 4th grade (n= 84) of the primary school of Santo of the City of Fafe. Methodology: The laterality of the hand and foot was assessed by The Dutch Handedness Questionnaire (Van Strien, 1992) e by the Coren e Porac (1978) questionnaire. Eight anthropometric measures were evaluated and four tests of physical fitness were conducted (handgrip, long jump with one foot, “sit and reach” test and the flexibility of shoulders test). Statistical procedures: median, average, standard deviation, scale, the Shapiro-Wilk test, linear correlation coefficient of Pearson, correlation coefficient, Spearman Rho, t test for independent measures, Mann-Whitney U test, Levene test, test T ranges from Wilcoxon, Eta test. The level of statistical significance was maintained at 5% (p£0.05). Results and conclusions: i) there are statistically significant differences between the right and left handgrip in boys and girls with 6/7 years; ii) there are statistically significant differences between right and left handgrip and between the “sit and reach” test in the boys of 9/10 years; iii) We found statistically significant differences between the right and left one foot long jump in the group of boys with 6/7 years; iv) Statistically significant differences were found between the right and left one foot long jump in groups of girls with 9/10 years; v) Statistically significant differences were noted between the right and left arm contracted circumference in the boys with 6/7 years and in the girls with 9/10 years; vii) Statistically significant differences were found between the right and left leg circumference in girls and boys with 9/10 years.
