Chapter Five▯ • Flexibility: the ability to move joints freely through their full range of motion▯ • Five factors that limit movements:▯ • 1) shape of bones▯ • 2) a stiff muscle▯ 3) the connective tissue▯ • • 4) tendons▯ • 5) tight skin▯ • Beneﬁts of ﬂexibility: increased joint mobility, efﬁcient body movement, good posture. Stretching DOES NOT protect muscle injury.▯ • Ligaments: connective tissue within the joint capsule that hold bones together▯ • Cartilage: a tough connective tissue that forms a pad on the end of long bones such as femur, tibia, humerus. Carilage acts as a shock absorber to cushion the weight of home on another and to provide protection from the friction due to joint movement.▯ • Stretch reﬂex: involuntary contraction of a muscle due to rapid stretching of that muscle▯ • Muscle spindles: the type of proprioceptor found within muscle▯ Proprioceptor: specialized receptor in muscle or tendon that provides feedback to the brain about the • position of body parts▯ • Golgi tendon organs: the type of proprioceptor found within tendons▯ • Hypokinetic disease: a disease associated with a lack of exercise — lower back pain.▯ • Sit-and-reach test: a ﬁtness test that measures the ability to ﬂex the trunk. (lower back and hamstrings)▯ • Shoulder ﬂexibility test: a ﬁtness test that measures the ability of the shoulder muscles to move through their full range of motion.▯ • Dynamic stretching: stretching that involves moving the joints through full range of motion to mimic a movement used in a sport or exercise.▯ • Ballistic stretching: a type of stretch that involves sudden and forceful bouncing to stretch the muscles.▯ • Static stretching: stretching that slowly lengthens a muscle to a point where further movement is limited.▯ • Proprioceptive neuromuscular facilitation (PNF): a series of movements combining stretching with alternating contraction and relaxation of muscles.▯ • Antagonist: the muscle on the opposite side of a joint. (stretching this promotes a reﬂect reaction of the muscle)▯
