RESUMEN
Abstract Aim: The purpose of the current study was to investigate the effects of considering single/ combined and raw/ standardized measures from the Körperkoordinationstest für Kinder (KTK) and Fitnessgram tests on the relation between GMC and HRPF in four age-groups. Method: Participated five-hundred thirty-one children and adolescents (279 boys). The individuals were divided into four groups: 4 to 7, 7 to 9.5, 9.5 to 12, 12 to 15 years of age. We utilized the KTK and Fitnessgram tests to measure, respectively, GMC and HRPF. Bootstrap correlations and χ2 tests were performed for all individuals, and each group controlling for sex. Results: For the raw scores, correlations were around (absolute) r = 0.37, except body composition, with large decreases when controlling for age and sex. For standardized tests, considering either the GMC quotient or GMC categories, correlations were all significant (around r = 0.34). Finally, considering broad categories (apt/non-apt and coordinated/non-coordinated), the association was 0.16. Conclusions: We found clear influences of the measure utilized on the association between GMC and HRPF measures.
