Document Summary
Sex: mental and psychological factors, postural deviations, neuromuscular, structural or performance factors. Poor posture causes: postural habits, adapting to culture, environment/ sport, attitude, physical strength, bony anomaly. Sport injuries: extrinsic factors: exposure to an injury situation, potential hazards and unique risks of the sport, position played, amount of training and playing time, competitive level, equipment, protective equipment, footwear. If equipment is not used or fitted properly it can cause injuries: poor regulation, weather conditions. Mechanical injury: external force impairs anatomical tissue structure or function causing injury. Injury will cause inflammatory response: starts with inflammation, beginning of tissue healing. Injury is dependent on tissue properties and force. Load: external force acting on the body causing internal reactions with the tissue, compression. Stiffness: ability of tissue to resist a load, stronger tissue = more stress it can tolerate. Internal change in tissue (length) resulting in deformation: over length or compress = deform it.
