osteoarthritis, osteoarthritis, osteoporosis, flexibility exercise, structure of a joint, osteoporosis, aging, muscle weakness associated, aging changes in posture, gait, universally associated, aging, in the skin, hair, skeleton provides support, structure, joints, the areas where bones come together, allow the skeleton to be flexible, movement, joint, bones, not directly contact each other, cushioned by cartilage, membranes, fluid, muscles provide the force, strength to move the body, coordination, directed by the brain, in the muscles, joints, in the posture, gait, weakness, slowed movement, in the muscles, joints, bones, aging changes, bone mass, density is lost, people age, in women after menopause, bones lose calcium, minerals, spine is made up of bones, vertebrae, between each bone, gel-like cushion, intervertebral disk, trunk becomes shorter, the disks gradually lose fluid, become thinner, vertebrae lose some of mineral content, making each bone thinner, spinal column becomes curved, compressed, packed together, bone spurs, aging, overall use, the spine, form on the vertebrae, shoulder blades, scapulae, bones, become porous, on an x-ray they, look "moth-eaten", foot arches, become less pronounced, contributing to slight loss of height, long bones, the arms, legs, more brittle, mineral losses, not change length, makes the arms, legs look longer, compared, shortened trunk, joints, become stiffer, less flexible, fluid, in the joints, decrease, cartilage, to rub together, erode, minerals, deposit, joints, calcification, common, in the shoulder, hip, knee joints, to lose structure, degenerative changes, finger joints lose cartilage, bones thicken slightly, finger joint changes, more common in women, hereditary, joints, ankle, experience little change, aging, lean body mass decreases, caused in part by loss of muscle tissue, atrophy, extent of muscle changes seems to be genetically determined, muscle changes often begin, in the 20s in men, 40s in women, lipofuscin, an age-related pigment, fat, deposited in muscle tissue, muscle fibers shrink, muscle tissue is replaced more slowly, lost muscle tissue replaced, a tough fibrous tissue, most noticeable, in the hands, appear thin, bony, muscle tissue changes, combined, normal aging changes, in the nervous system, muscles to have reduced tone, contractility, muscles, become rigid, lose tone, exercised regularly, effect of changes, bones, become more brittle, break more, height decreases, primarily, shortening, the trunk, spine, inflammation, pain, stiffness, deformity, result from breakdown, the joint structures, all elderly people, joint changes, ranging from minor stiffness to severe arthritis, posture, become progressively stooped, bent, knees, hips more flexed, neck, become tilted, shoulders, narrow the pelvis, become wider, movement slows, become limited, walking pattern, gait, becomes slower, shorter, walking, become unsteady, less arm swinging, fatigue occurs more readily, overall energy reduced, strength, endurance change, loss of muscle mass reduces strength, endurance enhanced by changes, in the muscle fibers, aging athletes, healthy hearts, lungs, find that performance improves in events that, require endurance, decreases slightly in events that, require short bursts of high-speed performance, common problems, osteoporosis, common problem, older women, broken bones occur more readily, compression fractures, the vertebrae, cause pain, reduce mobility, muscle weakness contributes to fatigue, weakness, reduced activity tolerance, joint problems, extremely common, from mild stiffness to debilitating arthritis, osteoarthritis, injury risk is greater, falls related to gait changes, instability, loss of balance, elderly people have reduced reflexes, most often, in the muscles, tendons rather than changes, in the nerves, decreased knee jerk, ankle jerk is not unexpected, positive babinski's reflex, always considered abnormal, involuntary movements, muscle tremors, fine movements, fasciculations, more common, in the elderly, inactive, immobile elderly people, experience weakness, abnormal sensations, paresthesias, muscle contractures, occur in those unable to move voluntarily, to have muscles stretched, exercise, restless leg syndrome, prevention, exercise is one, the best ways to slow, prevent problems, the muscles, joints, bones, a moderate exercise program, maintain strength, flexibility, exercise helps the bones to remain strong, consult, beginning a new exercise program, a well-balanced diet, adequate amounts of calcium is important, women need to be especially careful to get enough calcium, they age, postmenopausal women need 1,200-1,500 mg of calcium per day, have osteoporosis, prescription treatments, related topics, aging changes in body shape, aging changes in hormone production, aging changes in organs, tissues, cells, aging changes, in the nervous system, osteoporosis, calcium in diet.
