Abstract
O objetivo deste estudo foi comparar a potência correspondente à máxima fase estável de lactato sanguíneo determinada de forma contínua (MLSSC) e intermitente com recuperação ativa (MLSSI). Dez ciclistas treinados do sexo masculino (25 ± 4 anos; 72,5 ± 10,6 kg e 178,5 ± 4,0 cm), realizaram os seguintes testes, em um cicloergômetro: 1) incremental até a exaustão voluntária para a determinação da potência máxima (Pmax); 2) dois a cinco testes submáximos de carga constante para determinar a MLSSC, e; 3) dois a três testes submáximos de carga constante, consistindo de oito repetições de quatro minutos, com dois minutos de recuperação a 50% Pmax para determinar a MLSSI. A MLSSC (273,2 ± 21,4 W) foi significantemente menor do que a MLSSI (300,5 ± 23,9 W). Com base nestes resultados, verifica-se que o modelo de exercício intervalado utilizado permite um aumento de aproximadamente 10% na intensidade correspondente à MLSS.
The objective of this study was to compare the power corresponding to maximal lactate steady state determined through continuous (MLSSC) and intermittent protocol with active recovery (MLSSI). Ten trained male cyclists (25 ± 4 yr., 72.5 ± 10.6 kg, 178.5 ± 4.0 cm), performed the following tests on a cycle ergometer: (1) incremental test until voluntary exhaustion to determine the maximal power (Pmax); (2) two to five constant workload tests to determine MLSSC, and; 3) two to three constant workload tests to determine MLSSI, consisting on eight repetitions of four minutes interspersed by two minutes of recovery at 50% Pmax. The MLSSC (273.2 ± 21.4 W) was significantly lower than MLSSI (300.5 ± 23.9 W). With base on these data, it can be verified that the intermittent exercise mode utilized in this study, allows an increase of 10% approximately, in the exercise intensity corresponding to MLSS.
