Comparison of Fed and Fasted States

The Comparison of Fasted and Fed States of Subst lay Oxidation During Sub-maximal Exercise of distort Intensities Introduction: Substrate utilization and go fanaticism and time has be intensively studies over the previous years. To gain to a greater extent knowledge on which give notice is best for contrary types process and the nutrition to improve performance. The four major sources of qualification for employ ar muscle glycogen, blood glucose, plasma lusciousty acids and intramuscular triglycerides (Coyle, 1995), which are derivatives of the deuce most important substrates, pads and scratchs. The energy implement to power steady state aerobic exercise in state is derived predominantly from the oxidization of carbohydrate and fat (Coyle, 1995). Fats and carbohydrates are oxidized simultaneously but the relative contribution of these dickens substrates is dependent on a variety of factors including the exercise volume and duration, diet, environmental factors and training status (Jeukendrup, 2003). During low eagerness, moderate and high gear gear exercise the energy demand is change magnitude compared with resting conditions and both carbohydrate and fat oxidation increases.

When exercise intensity is change magnitude from rest, fat oxidation increases until a peak of approximately 65% VO2max is achieved, later on which a decline in the rate of fat oxidation is observed. In contrast to carbohydrate metamorphosis, which is increased as a function of aerobic work rate, fat oxidation is cut back at the high intensities (Jeukendrup, 2003) and carbohydrate oxidation is more predominant. carbohydrate! oxidation is dominant at higher intensities as people cannot oxidize fat at a high large rate to provide in all the energy required to fuel moderate to high intensity exercise (Coyle, 1995). High intensity exercise cannot be maintain for long periods of time as carbohydrate stores deplete and wear upon occurs. With increasing duration of exercise there are attach increases in fat metabolism and decreases in...If you want to get a full essay, order it on our website: OrderCustomPaper.com
