A COMPARATIVE STUDY OF AMOUNT OF ELECTRICAL ACTIVITY OF MUSCULUS RECTUS ABDOMINIS AND QUADRICEPS AT ABDOMEN TRAINING FROM DIFFERENT MECHANICAL POSITIONS

Currently, athletes and non-athletes are suffering from exerting double efforts with time which is supposed to lessen this effort because of other training applied in order to enhance other muscles separately which gives more benefits especially for the legs. This is one of the problems which sometimes lead to dangerous injuries especially for athletes who do not know the importance of choosing the optimal training position. The importance of this study lies in highlighting the load resulted from abdomen training with two different positions with contribution of some muscles through studying electricity and some variables of neural signal preparing these muscles to determine the best position which do not lead to put physical load or load on the spine or its vertebrae. The empirical method was used and the sample of the study was chosen purposively (8 body building players of Faculty of Physical Education ? Thi Qar University). Players performed abdomen and legs training in extending and bending positions. The most important conclusions of the study are: performing abdomen training with knee bending leads to better targeting towards abdomen muscles which was clear from muscle’s electrical activity, more participation of other muscles in positions of abdomen and legs extended, these muscles have special training that has to be applied separately and abdominal training performance from the position of legs extension forms more load on the spine which may result in some problems with time especially for non-athletes.
