Resumo: | It has been suggested that the participation of alactic anaerobic metabolism(AAM) in physical activity can be estimated by calculating the fast componentof excess post-exercise oxygen consumption (EPOCFAST). Considering that maximalaccumulated oxygen deficit (MAOD) represents the total amount of energytransferred by anaerobic metabolisms, this study aimed to analyze whethersubtracting EPOCFAST from MAOD (MAODLA-1) provides a satisfactory estimate oflactic anaerobic metabolism (LAM). For this purpose, MAODLA-1 was compared withthe method by which the energy derived from blood lactate accumulation (MAODLA-2)is expressed as oxygen equivalent. Nine active adult men were submitted to fourexperimental sessions: 1) a maximal incremental exercise test until exhaustionon a cycle ergometer to measure the maximal oxygen consumption (VO2max) and theexternal power corresponding to VO2max (WVO2max); 2) and 3) sixconstant-workload tests (3 per session) at intensities below WVO2max; 4) oneconstant-workload test at an intensity corresponding to 110% of W O2max. Themain finding was that both methods (MAODLA-1 e MAODLA-2) that were used toestimate the contribution of LAM in MAOD resulted in similar statistical values(p > 0.05). In addition, percentage values of MAODLA-1 (representing MAL) and EPOCFAST (representing AAM) were approximately 78 and 22%, respectively. Thus,the procedure proposed in this paper may be of interest to future studies onthe contribution of anaerobic components to MAOD. |

Considerando que o Déficit Máximo Acumulado de Oxigênio (MAOD) representa a quantidade total de energia transferida pelos metabolismos anaeróbios, o objetivo desse estudo foi analisar se o método de subtrair o EPOCRÁPIDO do MAOD (MAODLA-1) proporciona uma estimativa satisfatória do metabolismo anaeróbio lático (MAL). Para esse fim, o MAODLA-1 foi comparado ao método capaz de expressar em equivalente de oxigênio a energia oriunda do acúmulo de lactato no sangue (MAODLA-2). Nove homens adultos ativos foram submetidos a quarto sessões experimentais: 1) um teste progressivo até a exaustão em um cicloergômetro para a mensuração do consumo máximo de oxigênio (VO2max) e da potência externa correspondente ao O2max (WVO2max); 2 e 3) seis testes de cargas constantes (3 testes por sessão) com intensidades abaixo da WVO2max; 4) um teste de carga constante com a intensidade equivalente a 110% da WVO2max. O principal achado foi que os dois métodos (MAODLA-1 e MAODLA-2) empregados na estimativa da contribuição do MAL no MAOD geraram valores estatisticamente similares (p > 0,05). Além disso, os valores percentuais do MAODLA-1 (representando o MAL) e do EPOCRÁPIDO (representando o MAA) foram de aproximadamente 78% e 22%, respectivamente. Logo, os procedimentos propostos na presente investigação podem auxiliar futuros trabalhos que porventura objetivem fragmentar as contribuições dos componentes anaeróbio do MAOD.Universidade Federal de Santa Catarina.
