Comparação de 3 testes para determinar a velocidade de limiar em nadadores mirim I e II

Abstract

Introduction: the evaluation of the swimming training should be a trial continues, for an effective control of the training. Some methodologies you come being proposals for relate of stroke velocity with metabolic parameters, as the determination of the LAn through the behaviour of the blood lactate. In the present time indirect protocols as the Critical Velocity (Vcrit) and the Test of 30 minutes (T-30) are being utilized for determine the LAn through the relation time x distances. Objectives: it identify the LAn through the behaviour of the blood lactate, to Vcrit and the T-30 as indirect approaches of determination of the LAn. Methods: Swimmers of little category I and II, through the progressive test of 2 x 200 to 85 and 90% of best performance. It estimates critical velocity through the test of 100 meters and of 200 meters. And it verifies the velocity of stroke in the test T-30. Results: we verify that significant difference between the 3 velocities exists obtained and not correlation between the Vcrit exists and the progressive test of blood lactate. Conclusion: the speed of determined LAn by the blood lactate was over the others 2 indirect tests.
