Resumo: | Few studies in Africa have investigated the physical performance of children using the allometric method. This study evaluated the functional fitness of children and adolescents in a rural area of Mozambique using the contrast between theoretical models and empirical allometric coefficients. Height and weight were measured and functional fitness was assessed using the AAHPERD, EUROFIT and Fitnessgram tests. The allometric equation Y=aXb, was used. In addition to descriptive statistics, factorial ANOVA was used to test differences of body size and functional variables between sexes and age groups. An extension of the allometric equation based on ANCOVA was used after proper logarithmic transformation of all variables of interest. Mean height and weight increased with age and were significantly associated with age and sex. Functional fitness increased with age, and mean results were higher for boys. Allometric coefficients were different from those expected according to theory, and girls had higher coefficients in almost all tests. A marked sexual dimorphism was seen in functional fitness results according to age. Empirical coefficients were different from those expected according to theory, which demonstrated the absence of the presumed geometric similarity. Girls had higher coefficients than boys in all fitness tests. |

Allometric study of functional fitness of children and adolescents in a rural area of MozambiqueEstudo alométrico da aptidão funcional de crianças e jovens rurais de MoçambiqueFew studies in Africa have investigated the physical performance of children using the allometric method.

O estudo teve como objetivo averiguar a variabilidade da aptidão funcional de crianças e jovens rurais Moçambicanos por meio do contraste entre expoentes alométricos teóricos e empíricos. Foram medidas a altura e o peso, e avaliada a aptidão funcional com base em testes selecionados das baterias AAHPERD, EUROFIT e Fitnessgram. Foi considerada a equação alométrica fundamental, Y=aXb. Para além das estatísticas descritivas habituais, recorreu-se à ANOVA fatorial para determinar o efeito da idade e do sexo nas variáveis somáticas e funcionais. Aplicou-se uma extensão do modelo alométrico a partir da ANCOVA após transformação logarítmica das variáveis de interesse. Os valores médios de altura e peso aumentam em função da idade, interagindo significativamente com idade e sexo. Constatou-se um efeito da idade nas provas físicas, com maiores médias dos meninos. Os coeficientes alométricos encontrados são distintos dos esperados teoricamente, sendo maiores nas meninas do que nos meninos em quase todas as provas. Pode-se concluir que existe um dimorfismo sexual nas diferenças de médias na aptidão funcional ao longo da idade. Os expoentes empíricos encontrados, em ambos os sexos, são antagônicos aos esperados teoricamente, salientando ausência do pressuposto da similaridade geométrica. Nas meninas, os expoentes alométricos são, em todas as provas, maiores do que dos meninos.Universidade Federal de Santa Catarina. Florianópolis, SC.
