- Changes in motor competence over four decades in 10 to 14-year-old Austrian boys Klaus Greier Herbert Riechelmann Gerhard Ruedl Clemens Drenowatz Salud youth adolescents Motor skills secular trends physical fitness Background: Data on secular trends in motor competence in children and adolescents have been inconsistent. While several studies showed a decline in motor competence over the last several decades there is also research that showed no change or even an increase in motor competence in youth. Methods: In the present study motor competence was assessed via 6 test items in 10- to 14-year-old Austrian boys in the years 1972 (n=694), 1987 (n=138) and 2015 (n=222). At each meas- urement time participants performed 20m sprint, 800m run, sit ups, jump and reach, one-leg stand and stand and reach tests in the school gymnasium during regular school time. Data across measure- ment times was compared using weighted means across 5 age groups with pooled standard devia- tions. Results: Average performance on the 20m sprint, jump and reach test and one leg stand im- proved significantly (p<0.05) from 1972 to 2015 by 0.3 seconds, 3.9 cm and 3.5 seconds, respectively. Time for the 800m run increased significantly by 15% (p<0.01), indicating a decline in cardiorespira- tory endurance. Flexibility, measured by the stand and reach test, also declined significantly (p=0.02) from 1972 to 2015. There was no significant difference in the number of sit ups performed at the 3 measurement times. Conclusion: Results of the present study do not show a general decline in motor competence in male middle-school students over the last 4 decades. Rather, secular trends differ by specific components contributing to overall motor competence with declines in flexibility and endurance but increases in power, speed and balance. 2019 artículo científico 2414-6641 https://www.redalyc.org/articulo.oa?id=677873369009 en http://www.redalyc.org/revista.oa?id=6778 Current Issues in Sport Science application/pdf Universität Bern Current Issues in Sport Science (Suiza) Vol.4
