ABSTRACT
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.

Resumo O objetivo desta pesquisa foi comparar as variáveis antropométricas e de aptidão física de crianças e adolescentes de ambos os sexos em diferentes estágios de maturação sexual. Foram coletadas amostras de 436 escolares de Porto Velho, RO, 218 meninos e 218 meninas. Foi utilizado o protocolo de Tanner para dividir a amostra em relação aos estágios de 1 a 4 e na sequência foram coletados os dados de antropometria (peso, altura e IMC) e aptidão física (flexibilidade, força e corrida/caminhada). Este estudo caracterizou-se como "ex-post-facto", portanto, utilizou-se a média e desvio padrão, seguido de análise de variância (Anova "one-way") com "post-hoc" de Bonferroni, adotando um nível de significância de 5%. Não foram encontradas diferenças nas variáveis antropométricas para os dois sexos. Nos testes de aptidão física foram encontradas diferenças relativas à flexibilidade e corrida/caminhada no sexo feminino e nas variáveis força e corrida/caminhada no sexo masculino.
Abstract The purpose of this study was to compare the anthropometric and fitness variables of children and adolescents of both sexes at different stages of sexual maturation. The sample was composed by 436 students of Porto Velho, RO (218 boys and 218 girls). Tanner protocol was used to divide the sample in relation to the stages 1-4 and then anthropometry (weight, height and BMI) and physical fitness (flexibility, strength and run / walk) data were collected. This study was characterized as' 'ex post facto', so we used the mean and standard deviation, followed by analysis of variance (one-way ANOVA) with post-hoc Bonferroni, adopting a significance level of 5 %. There were no differences in anthropometric variables for both sexes. However, differences were found in flexibility and run/walk for females and in strength and running/walking for males.
