Physical and motor ability, anthropometrical and growth characteristics of boys in the Northwest Province of South Africa : a sport talent perspective

Abstract

The objective of the study was to analyse age group differences among and unique to 10 to 15 year old boys of different racial groups living in the North West Province (NWP) of South Africa. Boys (N=604) between 10 and 15 years participated in the study. They were a randomized group and a proportional representation of the four different racial groups living in the NWP. The tests included the Australian Talent Search protocol, consisting of 10 parameters (four anthropometrical, one physical and five motor abilities) and four additional physical fitness parameters (abdominal, grip- and upper body strength and flexibility). The analyses were based on cross sectional data and age group comparisons for anthropometric composition, physical and motor abilities of the boys. Analysis of Variance with an age and group effect revealed growth patterns similar to other studies, although unique growth characteristics were also found in the different racial groups, suggesting population variation. Age group differences and tendencies with regard to body dimensions and physical and motor abilities were indicated. In order to achieve a distinct profile of the current and future sporting potential of a boy in his rapid growing years, it is recommended that comparison to peers from a sport talent perspective will provide a more sensitive assessment when regional or national reference data, but also racial specific growth profiles, are used. The results of this study can serve as areference base for future comparisons in order to ensure that the most talented children are identified for sport on the basis of their own growth profile.
