Facts about stretching methods
Static stretch, neuromuscular facilitiation exercise and ballistic stretch

Static strecth: less likely to cause injury--done slowly and held for several seconds (low likely hood of tearing soft muscle) --Active Assistance: contract opposing muscle group to get reflex relaxation in muscles you are stretching--almost impossible to produce adequate overload by simply contacting those opposing muscles; passive assisstance: there is a prtner that aides your stretching, no relaxation in the muscles that associate with the stretch-- it is best to have both passive and active assistance so that you have the muscle relaxing but there is also sufficient force to overload it

PNF - most effective for improving fleibility, popular for rehab since the '60s, has many techniques to stimulate muscles to contract more strongly or to relax more fully so that they can be stretched; contract-relax-antagonist-contract technique is most pop. 3 steps: 1) move the limb so the muscle to be stretched is elongated initially then contract it isometrically for several seconds 2) relax the muscle 3) immediately statically stretch the muscle with the active assisstance of the antagonist muscle and an assist from a partner, gravity or other body part

Ballistic stretching is not recommended for most : momentum to produce the stretch, that momentum is produced by vigourous motion. Like static, it can be done actively or passively. That forceful movement can cause injury which is why it is not really heralded: there is a lack of control over the force and range of motion-- experts tell people to do synamic stretching instead: gradual and controlled movements up to the limit of the joints range of motion
antagonist muscle
in this concept, agnostic refers to the muscle group on the opposite side of the limb from the muscle group being stretched (i.e. biceps is agtagnostic of triceps)
agonist muscle
muscle group being stretched
ballistic stretch
muscles are stretched by the force of momentum of a body part that is bounced, swung, or jerked
measure of the range of motion available at a joint or group of joints. Determined by the shape of bones and cartilidge in the joint and by the length and extensibility of muscles, tendons, ligaments, and fascia that cross the joint
bands of tissue that connect bones. Unlike muscles and tendons, overstretching ligaments is not desirable
passive assisstance
stretch imposed on a muscle with the assistance of a force other than the opposing muscle
active assistance
an assist to stretch from an active contraction of the opposing (antagonist) muscle
PNF stretch
Proprioceptive Neuromuscular Facilitation Exercise - a type of static stretch most commonly characterized by a precontraction of the muscle to be stretched and a contraction of the antagonist muscle during the stretch
Static Stretch
a muscle is slowly stretched, then held in that stretched position for several seconds
Range of Motion
Exercises used to maintain existing joint mobility (to prevent loss of ROM)
Anabolic Steriod
synthetic steriods similar to the male sex hormone testosterone. They functio androgenically to stimulate male characteristics and anabolically to increase muscle mass, weight, bone maturation, and virility
Concentric Contraction
isotonic muscle contractions in which the muscle gets shorter as it contracts, such as when a joint is bent and two body parts move closer together
eccentric contraction
isotonic muscle contractions in which the muscle gets longer as it contracts - that is, when a weight is gradually lowered and teh contracting muscle gets longer as it gives up tension. eccentric contractions are also called negative exercise
increase in the size of muscles as a result of strength training; increase in bulk
isokinetic contraction
exercises done with a machine that regulates movement velocity and resistance
isometric contraction
type of muscle contraction in which the muscle remains the same length. Also known as static contraction
isotonic concentration
type of muscle conctraction in which the muscle changes length, either shortening (concentrically) or lengthening (eccentrically)
