Abstract

Tswana boys (n = 120) and girls (n = 120) performed test of hand grip strength, vertical and standing long jump, and maximum running speed. Mean values for performace at each age between 7 and 12 years were analysed using power functions to relate performance to body size as represented by height. Theoretical power function models for each task were constructed and actual results compared with these models. Differences between theoretical and empirical values are discussed in terms of body composition and skill level changes in this age range. Comparison of Tswana children with counterparts in developed countries is made in terms of physical education and sports opportunities available in each case. Planning and implementation of such programmes in developing countries is strongly recommended. Verf.-Referat
