Unformatted text preview: There are 2 types of linear flexibitlty tests: Relative and absolute flexibility tests: Relative Flexibility test: designed to be relative to the length or width of a
specific body part. Absolute Flexibility test: designed to measure only the movement in
relation to an absolute performance goal Tests: Sit and Reach- claim to measure lower back flexibility but they
better measure hamstring flexibility
- Modified sit and reach test: designed for those who have longer
legs with a shorter trunk and may have an advantage to a regular
sit and reach test Flexibility 12/5/14 7:02 PM When measuring flexibility, terms flexion and extension are used Flexibility is related to body size, gender, age and physical activity
- More related to habitua; movement patterns for each individual and for each joint than to age or to gender
Because individuals with good flexibility have greater ease of movement, less stiffness of muscles, enhancement of skill, and less chance of injury
during movement, the measure of flexibility should be included in all physical education and wellness programs
Too much range of motion however, can result in joint instability and can increase the possibility of injury
Three stretching techniques can be used to improve flexibility: static stretching, ballistic stretching, and proprioceptive neuromuscular facilitation
(PNF) Static Stretching: slowly moving to a positon to stretch the designated
muscles and holding the position for a specified length of time. Ballistic Stretching: makes use of repetitive bouncing motions. Though
ballistic stretching can improve stretching, it is not often recommended as a stretching technique.
- **if the force produced by the effort to stretch is greater than the extensibility the muscle tissues can tolerate, the muscle may be injured.
0 As the the individual is attempting to stretch through a bouncing action, he stretch reflex responds to prevent
the muscle from being stretched. Contracts quickly
0 The faster and more forceful the stretch, the faster and more forceful the contraction PNF Stretching: a combination of alternating contraction and relaxation of
both agonist and antagonist muscles (** disadvantage- require the assistance of a partner) Devices: Leighton flexometer, the electrogoniometer, and the goniomotor
(provide rotary measure inwhich degrees of rotation around 360 degrees ar determined ...
