Testing Methods for Anaerobic Peak Power and Anaerobic Mean Power

To understand the different methods in testing anaerobic power , we must first understand the very component that is the source of the power When the human body is in motion , it requires energy to propel it in motion . This energy source is supplied at the muscular level by the nucleotide called Adenosine Triphosphate ( Adenosine , Wiki

ATP is an energy-carrying molecule ( Adenosine , Wiki ) in the body which supplies energy through [banner_entry_middle]

chemical reaction with endorgenic molecules or cells within the body that require energy input (Farabee This energy source allows for muscle contraction , and the synthesis of proteins . When the body needs energy , for muscle contraction or biological processes , stored ATP undergoes hydrolysis , which produces energy , adenosine diphosphate (ADP , and inorganic phosphorus . ADP can be further broken down to adenosine monophosphate (ADM , inorganic phosphorus and more energy . To renew ATP , ADP (or ADM ) combines with inorganic phosphate found from the breakdown of carbohydrates , fats and sugar . The combination is accomplished in two processes

The first metabolic combination is called aerobic , because the formation of ATP is accomplished in the mitochondria , the basic cellular unit where respiration takes place ( Definition of , where ATP synthase , a respiratory enzyme , combine inorganic phosphorus with ADP during the oxidation of NADH (another enzyme used as an oxidizing agent . The second metabolic combination is called anaerobic , which literally means the absence of oxygen . Without oxygen or respiration , two enzymes , PGK and Pyruvate kinase act on inorganic phosphorus to combine with ADP and form ATP

At the beginning of movement , say in exercise , where oxygen has not circulated within the body , the energy used to propel the motion is said to be anaerobic , meaning the ATP used by the body was formed without oxygen . As the individual continues to work out , the energy supply moves to aerobic metabolism , where the body is able to circulate oxygen and use it to form ATP

It is worthy to note that during anaerobic metabolism , lactic acid results as a byproduct of the process . This chemical causes muscle pain , at the instantaneous moment of exercise , but not the cause of soreness occurring 24 hours after heavy muscular activity . This lactic acid is taken away as soon as aerobic metabolism occurs , and is oxidized in the kidneys to pyruvate , and then reconverted to glucose in a process called glucogenesis . This glucose is then used to form ATP and the cycle continues . This cycle is commonly referred to as the Cori cycle ( Lactic , Wiki . The presence of lactic acid or more significantly the absence of it , will be discussed in the testing methods of anaerobic mean power or anaerobic capacity , later in this

Though the two metabolic processes are listed consecutively , their action is not as such . Instead , during exercise both process almost happen simultaneously , with anaerobic metabolism dominating the first three to five minutes of an athletic activity , and as soon as oxygen… [banner_entry_footer]
