Types of defibrillation and muscles fibers

Types of defibrillation: - Constriction (Isometric Contraction): And is contractility without causing the palace, it is by the constant occurrence of constriction. Example: muscle-flexing as he does for bodybuilders and is a constriction of the muscle leads to the palace under tension. Constriction divides into two types: - Constriction positive (Concentric Contraction): Constriction takes place palace muscle to overcome the resistance. Example: Likely to in part positive. - Negative contraction (Eccentric Contraction): Constriction takes place lengthen the muscle to overcome the resistance. http://musclemaximizerprgrm.wordpress.com/2014/05/19/muscle-soreness-as-an-indicator-of-efficiency/
Types of muscle fibers: There are two types of muscle fibers: 1 - Rapid contraction of muscle fibers (Fast Twitch Fibers): The muscle fibers that contract quickly to give a large force for a short time, and is the largest fiber size and muscle in the greater proportion of these fibers when the person has increased the proportion of success in sports power, and body building. http://musclemaximizerprgrm.wordpress.com/2014/05/19/muscle-soreness/
2 - Slow muscle fiber contraction (Slow Twitch Fibers): The fibers that contract slowly and take long periods of work under medium voltage, these fibers are used in cardiovascular exercises and endurance exercises, and the greater the proportion of these fibers has increased the success rate of a person in endurance sports.
