posture的重要性

IMPORTANCE OF POSTURE
Neuromuscular effi ciency is the ability of the nervous system and musculature  system to communicate properly producing optimal movement. Proper postural alignment allows optimal neuromuscular effi ciency, which helps produce effective and safe movement (58–64). Proper posture ensures that the muscles of the body are optimally aligned at the proper length-tension relationships necessary for effi cient functioning of force-couples (58–64). This allows for proper arthrokinematics (joint motion) and effective absorp-tion and distribution of forces throughout the human movement system (kinetic chain), alleviating excess stress on joints (58–64). In other words, proper posture will help keep muscles at their proper length, allowing muscles to properly work together, ensuring proper joint motion, maximizing force production, and reducing the risk of injury.Proper posture helps the body produce high levels of functional strength. Without it, the body may degenerate or experience poor posture, altered movement patterns, and muscle imbalances. These dysfunctions can lead to common injuries such as ankle sprains, tendonitis, and low-back pain. However, a quick static postural observation can determine any gross deviations in overall posture.
