VALDIVIA, Alcibiades B. et al. Coordination readiness: multivariate profiles based upon age, sex, and socioeconomic status. Rev. Port. Cien. Desp. [online]. 2008, vol.8, n.1, pp.34-46. ISSN 1645-0523.

Purpose:To describe motor coordination levels (CoM), their centile distribution, as well as identify the coordinative readiness of Peruvian children as a function of age, sex and socioeconomic status. Methodology: Sample size included4007 children (n=1889 females; n=2118 males) between 6 and 11 years of age (young = 8,99; children = 9,07) from several schools of the metropolitan area of Lima, Perú. CoM was assessed with the KTK, a battery of tests that includes: balancing backward (BB), hopping on one leg (HO), jumping sideways (JS) and shifting platforms (SP). Socioeconomic status (SES) was assessed according to the physical localization of each school (type of neighborhood). Exploratory, descriptive and inferential statistical analyses were used, including: multivariate analysis of variance, discriminant function and chi square. Percentile charts were constructed in the LMS software version 1.32. Results: Significant increases in mean values of CoM were found in both sexes, and across age groups. Reclassification values of CoM in their original ages are low and  presents a decreased tendency throughout age (30% to 23% and 30% to 20% in girls and boys, respectively). SES is not a relevant predictor of differences in coordination profiles of children. Conclusions: The development of coordination is highly gender specific. There is a clear trend, in boys and girls, to show a coordination profile that is lower than expected for their chronological age. SES is not a conclusive predictor in the development of motor coordination profiles of children.
