Cardiac Muscle And Synthesis Essay

Pages 2
In the cardiac muscle, energy production from available substrates is obtained by step-by-step, enzymatically controlled substrate metabolism and mitochondrial oxidative phosphorylation, in which the energy content of fuels is transferred to the high-energy phosphate bonds of adenosine triphosphate (ATP). In turn, the energy necessary to produce contractile work from hydrolysis of ATP is produced primarily from the metabolism of carbohydrates and FFAs glucose metabolism is an important source of energy. It consists of two main components: glycolysis and glucose oxidation. The former has the advantage of producing ATP without requiring oxygen, but only contributes 5–10% of the overall ATP supply of the normal aerobic heart; it appears to play a special …show more content…
Fatty acid oxidation is the other major source of mitochondrial acetyl CoA production. This results from beta oxidation, which also provides reduced nicotinamide adenine dinucleotide and reduced flavin adenine dinucleotide for the electron transport chain. An important factor is that acetyl CoA originating from beta-oxidation competes with glucose oxidation as a source of acetyl CoA for the Krebs cycle; therefore, an increase in reduced nicotinamide adenine dinucleotide from beta-oxidation further contributes to the decrease in glucose oxidation. As a result, a high fatty acid oxidation rate will result in a marked decrease in the glucose oxidation rate; furthermore, although to a lesser extent, a high degree of fatty acid oxidation also inhibit glycolysis. Once acetyl CoA is produced it enters the Krebs cycle, where it is further oxidized and used to produce substrates for the electron transport chain. In the presence of oxygen, the electron transport chain will facilitate the phosphorylation of adenosine diphosphate to ATP, a process termed oxidative

Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive evidence-based...

Therefore, the structure of the subtle energetic body provides an intended means for human spiritual development, or evolution (which enables humanity to fulfill its purpose as a conduit between heaven and earth, hence transforming into an entity more subtle, and original).
