The most advanced technology has been used to photograph and reproduce this manuscript from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.Photographs included in the original manuscript have been reproduced xerographically in this copy.

In addition, OD was correlated with commonly used anaerobic capacity/power measures. Subjects were four distance and five middle distance runners, three sprinters, and four controls. Subjects performed one 2-3 minute supra-maximal treadmill run in which blood lactates were recorded, aWingate Bicycle Ergometer Test, and runs of 300, 400, and 600 meters. Data were analyzed by ANOVA and a Duncan's Multiple Range test. Significant differences in OD were found between: sprinters and middle distance runners vs. distance runners and controls suggesting a greater anaerobic capacity in the former t...

Determinação dos metabolismos lático e alático da capacidade anaeróbia por meio do consumo de oxigênio

“…Além disso, o MAOD, o tempo de permanência e a potência externa utilizada no teste supramá-ximo foram substancialmente menores que os reportados para ciclistas profissionais 26 . De certa forma, esses dados corroboram outros achados que demonstraram a capacidade do MAOD em diferenciar sujeitos com diferentes níveis de aptidão anaeróbia 29 .…”

Appetite, gut hormone and energy intake responses to low volume sprint interval and traditional endurance exercise

“…Individual regression equations were developed for each participant from the work rate/energy expenditure relationship during the maximum oxygen uptake test and used to estimate the energy expenditure of the average work rate of the 30 min session, thereby attempting to account for warm up, warm down, sprint and recovery periods. This method has been validated to provide a reliable relationship between work rate and energy expenditure (Medbø et al 1988) and as an estimate of the energy cost of supramaximal exercise (Scott et al 1991). Heart rate and RPE were recorded upon completion of each sprint.…”

“…The methods employed in the present study attempted to account for the oxygen deficit of the sprints (Medbø et al 1988;Scott et al 1991), which is thought to be the primary determinant of elevations in energy expenditure during the recovery periods (Hagberg et al 1980). However, it remains plausible that energy expenditure may have been underestimated as we did not account for other factors such as elevated body temperature, circulation and ventilation during recovery periods (Børsheim and Bahr 2003) or due to less efficient cycling at supramaximal workloads (Hunter et al 1998).…”

Déficit Máximo Acumulado De Oxigênio: Uma Breve Revisão Histórica E Metodológica

“…Ao final da década de 1980de , Medbø et al (1988 (SCOTT, 2006;MAXWELL;NIMMO, 1996;SCOTT et al, 1991). O MAOD também se mantém inalterado mediante a situação de hipóxia (MEDBØ et al, 1988) Tem-se sugerido que a capacidade de ressintetizar ATP anaerobiamente durante o exercício de alta intensidade e de curta duração é limitada (GASTIN, 1994), por isso se acredita que o MAOD é um método válido para se estimar a CAN, já que não é afetado pelo aumento do tempo de duração do exercício supramáximo (PRIPSTEIN et al, 1999;MEDBØ et al, 1988).…”

“…Em um estudo posterior, Medbø e Tabata (1993) Scott et al (1991) constataram que o MAOD se correlaciona significativamente com os índices proporcionados pelo teste de Wingate (potência de pico r = 0,69; potência média r = 0,64), com o trabalho total em exercício realizado em esteira com duração próxima a 120-130 segundos (r = 0,62) e com tempo na corrida de 300 m (r = -0,76). Dessa forma, esses pesquisadores sugeriram que esses testes são análogos na mensuração do desempenho anaeróbio e, conseqüentemente, que o MAOD é um método propício para avaliação da CAN.…”
