Document Summary
Musculoskeletal fitness as a function of age: threshold for dependence. Affecters of balance performance: body weight, strength/power, center of gravity. Improvement of balance: practice the specific balance test items, practice basic skills which demand a high degree of balance, participate in sports which demand a high degree of balance. Flexibility: flexibility range of movement about a joint or joints, considerations, not a general characteristic, static, dynamic (stiffness or looseness reflected in speed of movement or power) Importance: avoiding injuries, power development (plyometrics, muscle relaxation. Limitations of flexibility: mechanical factors: bone structure and muscle bulk, soft issue crossing a joint. Measurement of flexibility: goniometry, criticism: body proportions, avoid, flexometer (leighton, usually only used for research. Increase flexibility: through types of stretches, 1. Proprioceptive neuromuscular contraction of the muscle being stretched relaxes the antagonistic muscle: pnf superior to static and ballistic in increasing flexibility, however these exercises are complicated and often require trained partner, static stretches are an effective compromise.
