Such injuries may include joint immobilization for a period of time following surgery or joint injury. Overuse Overuse of a muscle without maintaining complete range of motion can cause lack of flexibility. Activities constantly performed without stretching will result in tight joints and muscles. Muscles, such as hamstrings, shorten from the continuous stress received in running, jumping, stopping and starting. Aging The effects of aging can cause muscle atrophy and lack of tissue elasticity.
Inactivity is a major cause of muscle weakness and causes progressive loss of muscle mass.
Rapid Growth Body coordination and flexibility are affected during times of rapid growth when the body displays rapid change in height or weight. This is a temporary condition as the muscle structure fails to keep up with the increased long bone or soft tissue growth.
