Guest guest Posted July 12, 2005 Report Share Posted July 12, 2005 Rodney and I have had a couple of off-list emails about bone densification due to muscle contraction. Bone density is determined by the amount of mechanical stress placed upon it by the connective tissue when the corresponding muscle contracts. The respective bone density will carry the load placed upon it, not more or less. A leg bone will sustain more stress than an arm bone because the leg muscles are stronger than the arm muscles. As you workout and become stronger, the body's adaptive process will increase the bone density as the muscle gets stronger. Workout less, the muscle's contractive force diminishes, and so does the bone density. Heavy steroid use can generate a quicker muscle response than the corresponding bone density can change, and the result can be the connective tissue tearing away from the bone. Swimmers hump is usually blessed upon the swimmers that are very good. The chest muscles, pectoralis minor and major, along with the latissimus dorsi become stronger than the corresponding back muscles. This will provide a muscle imbalance, with the chest muscles shortening, pulling the shoulders forward, as there is insufficient, relaxed, contractal force from the posterior deltoid region. Ya'll have a great day. Thanks Rodney for the good info. Don White Seguin, Tx Quote Link to comment Share on other sites More sharing options...
