“…Although the MAOD technique (Medbo et al 1988) has been criticised as an indirect measure of anaerobic energy system capacity (Bangsbo et al 1993) it has been reported in the recent literature for anaerobic capacity determination in athletic subjects in a number of sports including cycling (Craig et al 1993), swimming (Ogita et al 1996), rowing (Pripstein et al 1999) and track running (Spencer and Gastin 2001). Additionally, the study design that was used, together with good measurement precision (TEM 2.8 ml kg -1 ; see Methods), suggest that the MAOD is at least appropriate to track temporal changes in anaerobic capacity in the same athletes.…”

Nineteen well-trained cyclists (14 males and 5 females, mean initial .VO(2max) 62.3 ml kg(-1 )min(-1)) completed a multistage cycle ergometer test to determine maximal mean power output in 4 min (MMPO(4min)), maximal oxygen uptake (.VO(2max)) and maximal accumulated oxygen deficit (MAOD). The athletes were divided into three groups, each of which completed 5, 10 or 15 days of both a control condition (C) and live high:train low altitude exposure (LHTL). The C groups lived and trained at the ambient altitude of 610 m. The LHTL groups spent 8-10 h night(-1) in normobaric hypoxia at a simulated altitude of 2,650 m, and trained at the ambient altitude of 610 m. The changes to MMPO(4min), .VO(2max) and MAOD in response to LHTL altitude exposure were not significantly different for the 5-, 10- and 15-day treatment periods. For the pooled data from all three treatment periods, there were significant increases in MMPO(4min) [mean (SD) 5.15 (0.83) W kg(-1) vs 5.34 (0.78) W kg(-1)] and MAOD [50.1 (14.2) ml kg(-1) vs 54.9 (13.1) ml kg(-1)] in the LHTL athletes between pre- and post-altitude exposure. There were no significant changes in MMPO(4min) [5.09 (0.76) W kg(-1) vs 5.16 (0.86) W kg(-1)] or MAOD [50.5 (14.1) ml kg(-1) vs 49.1 (13.0) ml kg(-1)] in the C athletes over the corresponding period. There were significant increases in .VO(2max) in the athletes during both the LHTL [63.2 (9.0) ml kg(-1 )min(-1) vs 64.1 (9.0) ml kg(-1 )min(-1)] and C [62.0 (8.6) ml kg(-1 )min(-1) vs 63.4 (9.2) ml kg(-1 )min(-1)] conditions. In these athletes, there was no difference in the impact of 5, 10 or 15 days of LHTL on the increases observed in MMPO(4min), .VO(2max) or MAOD; and LHTL increased MMPO(4min) and MAOD more than training at low altitude alone.

“…In fact, many studies have investigated the energy contribution (Hagerman et al 1978;Mickelson and Hagerman 1982;Russel et al 1998;Pripstein et al 1999) and others physiological variables such as _ VO 2 and lactate concentration (Riechman et al 2002;Messonnier et al 2005;Beneke 1995) during a rowing ergometer. However, no study was found concerning the energy contribution or the _ VO 2 values during rowing in the water.…”

This study investigated the energy system contributions of rowers in three different conditions: rowing on an ergometer without and with the slide and rowing in the water. For this purpose, eight rowers were submitted to 2,000 m race simulations in each of the situations defined above. The fractions of the aerobic (W (AER)), anaerobic alactic (W (PCR)) and anaerobic lactic (W ([La-])) systems were calculated based on the oxygen uptake, the fast component of excess post-exercise oxygen uptake and changes in net blood lactate, respectively. In the water, the metabolic work was significantly higher [(851 (82) kJ] than during both ergometer [674 (60) kJ] and ergometer with slide [663 (65) kJ] (P < or = 0.05). The time in the water [515 (11) s] was higher (P < 0.001) than in the ergometers with [398 (10) s] and without the slide [402 (15) s], resulting in no difference when relative energy expenditure was considered: in the water [99 (9) kJ min(-1)], ergometer without the slide [99.6 (9) kJ min(-1)] and ergometer with the slide [100.2 (9.6) kJ min(-1)]. The respective contributions of the W (AER), W (PCR) and W ([La-]) systems were water = 87 (2), 7 (2) and 6 (2)%, ergometer = 84 (2), 7 (2) and 9 (2)%, and ergometer with the slide = 84 (2), 7 (2) and 9 (1)%. VO2, HR and lactate were not different among conditions. These results seem to indicate that the ergometer braking system simulates conditions of a bigger and faster boat and not a single scull. Probably, a 2,500 m test should be used to properly simulate in the water single-scull race.

“…A capacidade anaeróbia (CAN), definida como a quantidade total de energia transferida pelos metabolismos anaeróbios, durante a execução de um exercício de alta intensidade 3 , pode ser estabelecida com precisão pela análise direta dos substratos do metabolismo anaeróbio, os quais são obtidos por meio de biópsia muscular antes e após o exercício físico 4 . No entanto, em virtude da característica invasiva dessa técnica e da dificuldade em se estimar a massa muscular envolvida, alguns estudos têm empregado o Déficit Máximo Acumulado de Oxigênio (MAOD) na determinação da contribuição anaeróbia em diversas tarefas esportivas 1,5 . Alguns estudos têm apresentado limitações acerca do MAOD [6][7] .…”

Resumo -Tem sido sugerido que a participação do metabolismo anaeróbio alático (MAA) pode ser estimada a partir do cálculo da fase rápida do excesso do consumo de oxigênio após o exercício (EPOC RÁPIDO ). 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 EPOC RÁPIDO do MAOD (MAOD LA-1 ) proporciona uma estimativa satisfatória do metabolismo anaeróbio lático (MAL). Para esse fim, o MAOD LA-1 foi comparado ao método capaz de expressar em equivalente de oxigênio a energia oriunda do acúmulo de lactato no sangue (MAOD LA-2 ). Nove homens adultos ativos foram submetidos a quatro sessões experimentais: 1) um teste progressivo até a exaustão em um cicloergômetro para a mensuração do consumo máximo de oxigênio (VO 2max ) e da potência externa correspondente ao VO 2max (WVO 2max ); 2 e 3) seis testes de cargas constantes (3 testes por sessão) com intensidades abaixo da WVO 2max ; 4) um teste de carga constante com a intensidade equivalente a 110% da WVO 2max . O principal achado foi que os dois métodos (MAOD LA-1 e MAOD LA-2 ) empregados na estimativa da contribuição do MAL no MAOD geraram valores estatisticamente similares (p > 0,05). Além disso, os valores percentuais do MAOD LA-1 (representando o MAL) e do EPOC RÁPIDO (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.

Abstract -It has been suggested that the participation of alactic anaerobic metabolism (AAM) in physical activity can be estimated by calculating the fast component of excess post-exercise oxygen consumption (EPOC FAST ). Considering that maximal accumulated oxygen deficit (MAOD) represents the total amount of energy transferred by anaerobic metabolisms, this study aimed to analyze whether subtracting EPOC FAST from MAOD (MAOD LA-1 ) provides a satisfactory estimate of lactic anaerobic metabolism (LAM
