Adaptação do teste de Borsetto para avaliação anaeróbia de jovens corredores

Abstract

Laboratory and field tests are used to evaluate Anaerobic Power (AnP) e Anaerobic Capacity (AnC). The field tests are easy access, generally low-cost, practical alternatives and are considered more applicable to the evaluation routine in athletics teams. The Borsetto test (TBor 200 m) is a field test in which the evaluated must run 1000 m in submaximal effort, and then 200 m in maximal effort to evaluate the running speed produced by lactic power. This method minimizes the speed produced by the aerobic glycolisis, which makes it an efficient test for anaerobic evaluation. The time and speed of a 300 m run has been used for AnC evaluation. In this way, the objective of this study is to verify if the adaptation of Borsetto Test, using 300 m run in maximal effort after 1000 m run in submaximal effort (300 m TBor) would be more efficient than the 200 m TBor to exhaust anaerobic reserves (AnR) and, for this reason, to evaluate the AnC of young runners in a more specific way; verify if the 200 m TBor and the 300 m TBor can discriminate AnC in different groups of runners and verify the relation between final heart rate (Final HR), Fatigue rate (FR) and maximal lactate (ML) variables with the tests results. 15 young males participated in the study (8 sprinters and 7 middle distance runners) at about 17,0 ± 1,6 years old, 62,66 ± 7,67 kg of body mass, 176,34 ± 5,80 cm height who practice athletics for at least 10 months and at most 96 months. The evaluations happened in 4 meetings, being performed: anamnesis, anthropometric evaluation, Léger and Boucher tests to obtain aerobic speed peak (ASP); and randomly, the 200 m TBor and the 300 m TBor, to obtain: AnR, Max lactate, FR, final HR and subjective effort perception (SEP) of each test. Final SEP and final HR indicate that the athletes performed intense effort on the tests. The 200 m TBor AnR is higher than the 300 m TBor both for sprinters and long distance runners, both tests can discriminate AnC between the groups. Sprinters have higher AnC and long distance runners have higher ASP. Time and speed of maximal runs indicate that the 300 m TBor is influenced by aerobic metabolism, because it has shown significant correlation with ASP. Maximal lactate, FR and Final HR were the same for both groups and haven’t shown correlation with the results of the tests, except for the 300m TBor Final HR that has shown correlation with AnR%. It can be concluded that the 200 m TBor is efficient to evaluate the AnC, as it discriminates trained groups of young runners and AnR evaluation is influenced by aerobic metabolism on this test.
