Summary: |
Introduction: Although children and youth currently form the most active segments of the population in the westernized world, there is a
marked trend towards an increase in sedentary lifestyle and a decrease in physical fitness among school-age children. In order to counteract the suspected degradation, potential determinants must be known. Previous studies are based on non-representative samples mostly and are only conditionally comparable. Therefore, reliable findings on the determinants of physical fitness are not available. The purpose of the study is the identification of correlates of physical fitness in childhood and adolescence. It is assumed that physical fitness is associated with intrapersonal, behavioural and ecological factors. Method: Data were obtained from the “Luxembourg project”, a representative sample of the 9, 14- and 18-year-old boys and girls from Luxembourg (N = 1188). Physical fitness was measured on the basis of ten motor description categories such as aerobic endurance and flexibility by using a standardised test profile. Intrapersonal (e.g. BMI, sports interest), behavioural (e.g. extent of physical activity; p.a.) and ecological (e.g. peer-group behaviour, socio-economic status; ses) factors were assessed by using a standardised questionnaire (cf. Bös et al., 2006). Results: Ten multiple regression equations with sequential entry of the model levels help to confirm the suspected relation for eight out of ten motor description categories. Percentage of declared total variance is between 8.0% (fine motor abilities on precision tasks; F=5.19; p=.000; adjusted R²=.080) and 58.1% (speed of force development in lower extremities; F=67.70; p=.000; adjusted R²=.581). The identified effects and their directions can be clarified by the example of gross motor abilities under time pressure (F=35.98; p=.000; adjusted R²=.241). The performance in jumping sideways rises with increasing age (Beta=.64; T=17.52; p=.000), sports interest (Beta=.12; T=4.19; p=.000) and ses (Beta=.10; T=3.51; p=.000) as well as under the influence of an increased extent of p.a. in sports club (Beta=.15; T=5,10; p=.000), whereas lower performances become obvious with increasing BMI (Beta=-.12; T=-3.95; p=.000). Perspectives The results delimit the spectrum of potential correlates of physical fitness. However, the related design does not permit any causal conclusions. To receive reliable statements about the determinants of motor development in childhood and adolescence, the individuals included here will be examined prospectively in the context of a longitudinal section study. |
