Flexibility and Back Health Key Concepts
● Flexibility
– The ability of joints to move through a full
range of motion
● Stretching
– Should be included in a complete fitness
program, along with range-of-motion
movements
What Are the Benefits of Stretching and
Flexibility?
● Improved mobility, posture, and balance
● Healthy joints and pain management
● Possible reduction of future lower-back pain
● Muscle relaxation and stress relief
What Determines My Flexibility?
● Flexibility can be classified as static or dynamic.
– Static (passive) flexibility
● A measure of the limits of a joint
- overall range of
motion
– Dynamic (active) flexibility
● A measure of overall joint stiffness during
movement
Joint structures, and muscles and tendons
– Joint: the point of contact between two or
more bones
– Joint stability is supported by surrounding
muscles and tendons.
– Joint range of motion is limited by:
● Joint structures (cartilage, ligaments, membranes,
and fluids)
● Muscles and tendons (muscles and connective
tissues)
● The nervous system
– Also limits the range of motion in joints
– Stimulates muscle contractions
– Has receptors on muscles and tendons that
interpret muscular information
– Receptors include Golgi tendon organs and
