Blood lactate response after high intensity exercise is not dependent on aerobic capacity

Abstract

This study was delineated to analyze the relationships between the aerobic capacity and the increased and decreased rates of blood lactate after high-intensity exercise. Seven male individuals performed two evaluations in outdoor athletic track: a) a sprint of 200 m in the maximum speed (T200) to determine the blood lactate kinetics after intense exercise and b) a progressive test to determine the Anaerobic Threshold (LAn). The average of the LAn was 13.8 (1.4) km.h-1. There were not significant correlations between LAn and the initial rates of increase and decrease of blood lactate after T200 (r = 0.07, p= 0.88 e r = - 0.46, p= 0.31, respectively). There are no evidences that the aerobic capacity can be a determinant factor in kinetic response of the blood lactate after high-intensity exercise.
