High- and Low-carb Diet and Fasting State Modify Alternative Maximal Accumulated Oxygen Deficit

Description
Summary:This investigation aimed to assess whether the alternative method of estimating the maximal accumulated oxygen deficit (MAOD ) can detect changes in energy system contribution in different substrate availabilities. Following a graded exercise test to determine maximal oxygen uptake intensity (iVO ), 26 recreational runners performed a time to exhaustion effort (TTE) as baseline at 110% iVO . The same TTE was performed in fasting state, then, a muscle glycogen depletion protocol was executed. Subsequently, participants received a low-carbohydrate diet and beverages containing high (H-CHO, 10.8±2.1 g·kg ), moderate (M-CHO, 5.6±1.1 g·kg ), or zero (Z-CHO, 0.24±0.05 g·kg ) carbohydrates. Another TTE was performed 24 h later. Each energy system contribution was assessed. Generalized linear mixed models were used for statistical analysis (p
