Resumo

The purpose of this study was to investigate differences in running tests and soccer skills according to competition level over a three-year period (1996–1998). The running tests were: 30 m dash (dash), 10x5 m shuttle run (SHR), endurance shuttle run (ESHR), and tempo shuttle run (TSHR). The soccer tests consisted of juggling, dribbling, accuracy of kicking, and accuracy of lob. Three competition levels were selected: high (national division I and II, N = 26), moderate (national division III and IV, N = 23), and low (provincial divisions, N = 13). In 1998, annually measured pubertal boys (between 13 and 14 years of age) who remained in the same competition level during the previous years were selected. Tanner-Whitehouse II method was used to assess skeletal age. ANOVA for repeated measures showed increasing performance over time for all tests (p < .05), except for dribbling and accuracy of kicking. Significant differences were found between the highest and the lowest competition level (p < .05), except for TSHR. Moderate level is not shown in table. Interaction between age and level was only found in dash, SHR, and TSHR. Skeletal age as measured by TWII did not reveal as a significant covariate in the analysis. Competition level in 1998 was predicted via discriminant analysis using running and soccer tests as independent variables. Based on the four soccer specific tests, 59.4% of the sample was classified correctly. By adding the four running tests, predicted group membership increased to 76.8%. These results indicate that selection at high level occurs before the age of 11 years, since differences in running and soccer specific tests already existed in 1996. Differences between the competition levels did not change over time, suggesting that training at the highest level (three times a week) is not resulting in substantial increase in performance compared to the low competition level (once a week). Therefore, reconsidering training quality is of main importance. Supported by Nationale Loterij België, N 2811-02ATable
