An Alternate To Accumulated Oxygen Deficit (Aod) For Measuring Anaerobic Contribution: ‘Aodalt’ Is Valid In Normoxia And Hypoxia, Austin Shaw, John Michael Mihalek, David W. Hill

International Journal of Exercise Science: Conference Proceedings

Accumulated oxygen deficit (AOD) is the gold standard measure of anaerobic contribution; however, its calculation requires several contentious assumptions and it is time-consuming, requiring participants to perform a number of submaximal exercise bouts to establish exercise efficiency. A new method, AODalt, requires performance of only a single bout of exercise, and is based on the presumption that the fast phase of the post-exercise oxygen uptake (VO₂) profile reflects the alactic or phosphocreatine (PCr) contribution and that the exercise-induced increase in blood lactate concentration is quantitatively related to the lactic or glycolytic contribution representing a measure of total anaerobic …

Effect Of The Physical Inactivity Duration On Postprandial Lipid Metabolism The Morning After Exercise, Jieting Wang, Chelsea Merseal, Hadi Fareed, Remzi Satiroglu, Edward Coyle

International Journal of Exercise Science: Conference Proceedings

In physically active people (e.g., ~8,000 steps/d), an acute bout of exercise improves postprandial fat metabolism when measured the morning after exercise. However, in people who have been inactive for more than two days, the acute bout of exercise does not improve postprandial fat metabolism as reflected by a greater increase in plasma triglyceride concentration and a reduced whole body fat oxidation. This phenomenon whereby fat metabolism is suppressed by prior inactivity is termed ‘exercise resistance’. PURPOSE: The purpose was to determine if shorter periods (i.e., less than two days) of inactivity (i.e., 12, 24, 36 h) induce ‘exercise …
