provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down‚ a phosphate molecule is broken off‚ reducing the phosphate molecules‚ from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue‚ the ATP has to rebuild from ADP and p (ADP+P+= ATP). As this occurs‚ more energy is released and so more energy is available. Therefore‚ when the muscles is used for an extended time the ATP supplies are lowered. This is the most important

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and

Relaxation -Muscle is shortened‚ returns to zero and back initial length. In activity 2 how long was the latent period? It was 2.2 msec. Describe the chemical changes that are occurring during this period. Calcium levels are low since muscle contraction is not at its peak. Preparing on the contraction Ca begin the process of sending

activities of daily living. PNF is a type of passive stretching that uses alternating contraction and relaxation movements to increase flexibility. The reason why PNF is better than other forms of flexibility training is that it helps the body’s muscular inhibition. For the elite performer‚ the most useful type of PNF is the CRAC (contract-relax‚ antagonist-contract) technique‚ which uses isometric muscle contractions as its basis. PNF stretching is best performed with a partner. Muscle recruitment is
