RESUMO

Este estudo tem como objectivos: (i) explorar as relações entre o índice de massa corporal (IMC) e a percepção de competência física (PCF e/ou a Competência Efectiva em Basquetebol CEB; (ii) perceber a relação entre a PCF e a CEB, e (ii) determinar quais são as fontes de informação que os jovens utilizam para determinar a percepção de competência física.

Para tal, foi aplicado a 156 jovens estudantes com idades compreendidas entre os 12 e 18 anos (M=14.36; SD=1.76), a subescala de percepção de competência física (SPCF), a escala de informação de competência física (PCIS) e um protocolo para a competência efectiva em Basquetebol.

Os principais resultados revelaram: (i) diferenças estatisticamente significativas entre sexos para o IMC, apresentando os rapazes valores médios mais elevados; (ii) média superior dos rapazes superior às raparigas, para a PCF e CEB; (iii) diferenças estatisticamente significativas entre sexos para os seguintes factores do PCIS: negativismo pré-competitivo e atracção pelo Desporto; e, (iv) diferenças estatisticamente significativas entre as diferentes faixas etárias para o factor avaliação dos pais.

Relatioships between physical aptitude perception, body mass index and true aptitude in young basketball players

ABSTRACT

The purposes of this study were: (i) explore the relationship between Body Mass Index (BMI) and Perceived Physical Competence (PPC), and/or Effective Basketball Competence (ECB); (ii) understand the relationship between PPC and ECB; and, (iii) establish the sources of information that the young use to define the PPC.

A sample of 156 physical education students, with ages ranging from 12 to 18 years (M=14.36; SD=1.76), completed the perception of physical competence subscale (PPCS) and the physical competence source’s subscale (PCSS). They also realized a protocol to measure effective competence in Basketball.

The main results revealed: (i) significant differences between boys and girls, while comparing BMI, with higher mean scores for boys; (ii) higher mean scores of PPC and BEC for boys; (iii) significant differences for the following constructs of the PCSS: pre-competition anxiety and sport attraction; and, (iv) significant differences between different groups of ages, for parent’s evaluation factor.

Key words: Physical aptitude perception, body mass index, Basketball
