Muscles. contraction types. muscle types. muscle fibre types.

Define agonist The muscle primarily responible for producing movement.
Define antagonist the muscle that relaxes as the antagonist ontracts to allow ease of movement and minimise the risk of injury.
Define Stabilisers muscles that act to stabilise the bone where the prime mover is acting to allow effiviency of movement and maximal contrsctile force to be developed if required.
Define reciprocal inhibition when muscles on one side of the bone or joint relax to accommodate contration on the other side of the bone or joint.
Define all or nothing principle The physiology definition has to do with the action potentials that are generated within the central nervous system and are shot down to a specific muscle group.
Define capillary density Your capillaries on a basic level are small blood vessels that supply your muscles with blood.
Define phosphocreatine stores Phosphocreatine, also known as creatine phosphate, is in an organic molecule that enables the expression in the muscles of explosive power lasting no longer than about 8 seconds.
Define triglyceride stores the optimum state of fatty acids in order to enable storage.
Isotonic contractions. - concentric Concentric contractions are those which cause the muscle to shorten as it contracts.Concentric contractions are the most common type of muscle contraction and occur frequently in daily and sporting activities.
- eccentric Eccentric contractions are the opposite of concentric and occur when the muscle lengthens as it contracts.This type on contraction puts a lot of strain through the muscle and is commonly involved in muscle injuries.
Isometrically a muscle contraction where there is no change in its length.
Smooth muscle Muscle tissue that contracts without conscious control, having the form of thin layers or sheets made up of spindle-shaped, unstriated cells with single nuclei and found in the walls of the internal organs.
cardiac muscle The specialised striated muscle tissue of the heart; the myocardium.
Skeletal muscle Muscle attached to bone and, in some areas, skin. Contraction of the muscle moves parts of the skeleton. Skeletal muscle is sometimes called voluntary muscle because its actions are usually under conscious control.
Slow-twitch Slow-twitch is a muscle that contracts slowerly and does not need oxygen. eg cross country.
Fast-twitch oxidative Also has the meaning fast-twitch A. This means that it can be partially trained to be more like a slow-twitch. Meaning you have better chance of training someone that is fast-twict A, then someone that is fast-twict B. eg running/excirse.
Fast-twitch glycolytic Also has the meaning fast-twictch B. This means that it cant be trained and is anaerobic. Meaning you cannot change this person, and can not train someone that Is fast-twitch B to do running/cross country.
Mitochondrial density cellular structures containing enymes responsible for the production of energy under aerobic conditions.
oxidative enzymes
myoglobin content a pigment similar to haemoglobinwhich transports oxgyen to the mitochondria where aerobic glycolysis takes place
Fatigue resistance Allows the body to keep working without getting tired and run down.
