In Rugby when you are pushing against each other( in a rugby scrum) your muscles contract but stay the same length and this is isometric contraction. Even though you are using a lot of force your muscles stay the same length.
A muscles contraction (also known as a muscle twitch or simply twitch) occurs when a http://www.answers.com/topic/skeletal-muscle generates tension through the action of http://www.answers.com/topic/actin and http://www.answers.com/topic/myosin cross-bridge cycling.

iswear down dont know it :-D
Isometric contractions are static contractions during which muscle fibres do not change length. There is no movement of the joint to which the muscle is attached but energy is expended resisting a force that does not move. for example when you put your hands up for a long time.
There are 3 types of muscle contraction in the leg extention and they are Concentric, Isometric, and Eccentric contractions.
Different types of muscle contractions
How many different types of musclesare there in the human body? How many different types of musclesare there in the human body?
eccentric and concentric contractions
The most common headaches are either muscular or migraines; which are vascular in origin.
Soccer, Football, basketball, boxing, Rugby, Baseball, wrestling
These two tests measure different types of muscular strength.YMCA bench test, is looking at local muscular endurance, while 1 RM testing is looking at maximal muscular strength.Muscular strength is a measure of fitness that can be defined as the maximal forces generated by a specific muscle.Muscular endurance is the ability of a muscle to cause repeated contractions over a period long enough to cause muscle fatigue.
Muscles are tissues that are specialized for contractions.
True synergy is when a muscle that crosses two joints is restricted at one joint by another muscle. There are are two types of synergy:Helping synergy is when two muscles contract simultaneously to produce one movement.True synergy is when a different muscle contracts to stop the secondary action of another muscle.
Epithelial, connective, muscular, and nervous tissues.
