Introduction The structure and function of the skeleton, joints and muscles is essential to the support and movement of the human body. To create movement in the body, two main systems are used. The first of which is the skeletal system, which protects and supports the body organs and provides a framework the muscles in the body use to cause movement. Secondly, the muscular system, which allows manipulation of the environment, locomotion, and facial expression. The muscular system also maintains posture and produces heat. "Just about all movements of the human body are a result of muscle contraction" (Elaine N. Marieb, 1999, page 157) This statement is true, however it is not muscles alone which produce movement as the skeletal and joints play a main part too. ...read more.

Figure 1.2 - Diagram to show comparison of normal and osteoporosis bone. (http://yourmedicalsource.com/library/osteoporosis/OSP_whatis.html) This could truly affect the participation of sport as the bones are constantly taking punishment in most sports and exercises. Physical activities that involve twisting, bending, or high impact can be dangerous for those already diagnosed with low bone density. Sports such as golf, tennis, bowling and aerobics, basketball and jogging may do more harm than good. This is because athletes involved in sports and training where forces applied to the limbs are in excess of 10 times body weight (gymnastics, weightlifting and volleyball) have been found to have higher BMD than those involved in sports where forces are only in the range of 5-10 times body weight, such as endurance running. (www.nof.org) There is general agreement that weight bearing exercise is very helpful in increasing bone density, however this stresses only the lower body. Current research indicates that strength training also can increase bone density, as well as improve balance, mobility and flexibility. It would be best for people to begin strength training long before their bones started to thin. Other factors which contribute to a loss of bone density include smoking, caffeine and inadequate or inappropriate diet. ...read more.

Conclusion

The muscles that will be concentrated on most will be the bicep, brachialis and the triceps around the elbow joint of the initial straightening movement of the jab. In the Elbow joint, as the arm snaps away, the triceps is the agonist and the bicep the antagonist. The triceps origin is proximal 1/3 of posterolateral aspect of the humerus. Its insertion is the olecranon process of the ulna and it gets its blood supply from the posterior humeral circumflex and the profundus branch of the brachial. (W. Wirhed, 1990) Figure 1.7 - Diagram The Fixator is another muscle which contributes to the action of the principal muscle. The Fixators when doing a jab are shown in Figure 1.8 Figure 1.8 - Table to show the Fixators from a boxing jab Fixators Latissimus Dorsi Deltoid Sternocleidomastoid These Fixators are just part of the whole process involved in movement. The skeletal and muscular system work in harmony to produce movement but there is a lot more details which have not been discussed which also contribute to movement such as the brain and nervous system. Movement is an element of our body which we take for granted and a lot of people don't realize that if just one component is not working properly or is diseased then it effects the entire movement. ...read more.
