Interabdominal pressure is also raised during an all-out effort, and, for that reason, persons with hernia or a weak abdominal wall should not attempt heavy lifting exercises. An unsuspected hernia may become evident during exercise when a boy complains of a burning sensation or other pain or discomfort in his groin. The supervisor of a weight training program should be alert to this danger and caution the participants in advance, so that they may inform him if any suspicious circumstances occur.
There is seldom any danger of trauma or injury to the muscle fiber as a result of lifting. Physiological deterrents intervene to protect the organic systems of the human body. The psychological limit is usually reached and the human will fails, long before the physiological limit is usually reached.
Ligament and joint injury is more often caused by an improperly performed exercise or by the use of straps to fix loads to the body. Such injuries are usually minor and recovery is spontaneous. Some evidence of trauma to supporting structures such as ligaments and tendons has been found, even though tension usually develops too slowly to produce muscle tears from weight lifting.
A word of caution is in order about pushing high school or younger boys too hard. The leader should know the boy and know whom to encourage and whom to moderate. Larger boys may need encouraging, for according to his size he should be lifting with the stronger boys.
The programs recommended in the following chapters are applicable equally to high school, college or professional athletes. We have used the same programs with all three groups and there is no good reason to alter those that are offered in each sport solely because of the age differences.
The nomenclature of joint actions is admittedly confusing because of its inconsistent terminology, but most of the movements have rather familiar terms, which can be adequately described. It is not necessary to be an expert to participate in weight training. However, if one is going to instruct a squad it is very important that he understand the musculature and the joint action of the body in order to design a simple training routine.
For the purpose of defining joint actions, it should be assumed that the body is in an anatomical position, which is the erect standing position with the arms hanging by the sides and the palms of the hands facing forward. The fundamental body movements either start from or return to this position.
