المستخلص: احتوى الباب الاول على مقدمة البحث واهميته التي تكمن في وضع تمرينات بالاثقال وبيان تاثيرها في بعض المتغيرات الوظيفية والبايوكيميائية المصاحبة لمرحلة الاعداد الخاص للاعبي الشباب بكرة القدم والمتمثلة في قياس (حامض اللاكتيك قبل الجهد وبعده، معدل ضربات القل | The thesis comprised five chapters; chapter one gives an introduction to the topic under investigation as well as dealing with its significance which lays in the Impact of Weight - Compound Training on some Physiological and Biochemical Changes accompanying special preparation of Young Footballers specified in measuring (Lactic Acid preceding and following effort, pulse, Creatine and creatinephosphokainiz enzyme). Compound exercise is a new trend characterized as being more challenging than traditional methods of training, a fact that makes its application within a scientific and experimental way to gain an increase in the probability of influencing some physiological and biochemical changes in young footballers. This chapter deals also with the problem that is formed in answering two questions which are; (are there weight compound exercises in youth's training courses?) and (what is the type of weight compound exercises impact on physiological and biochemical changes?). The significance of the study is in answering these two questions.Aims of the Study : ? Forming weight compound exercises for footballers.? Gauging the impact of weight compound exercises on some physiological and biochemical changes.Hypotheses : ? There are significant statistical variations between the pre and posttests results of the experimental and controlling groups in physiological and biochemical changes of young footballers.? There are significant statistical variations in the post test results between the experimental and controlling groups in the physiological and biochemical changes of young footballers.Method and Practical Processes : Chapter three of the thesis sheds light on the way of choosing the method and processes of the study. The researcher applies the experimental method on a sample of (12) Diyala youth football team players. The experimental group is trained according to the training process by using weight compound exercises for two months/ 3 units per week. The researcher conducted the exploratory experiment to ensure main experimentation success, the doing the pretests within the frame of the experimentation method after setting forth the physiological and biochemical changes. After that the tests are repeated after finishing the weight compound training of the experimentation method. Results are conducted statistically by using the (SPSS) statistical package and performing suitable formulae in finding the results.Conclusions : ? The biochemical variations in addition to pulse are positively affected by the type and form of obtained exercises due to the change in exercise mode. ? Results showed that pre - effort Lactic acid ratios remained within close ranges in the experimental group prone to relaxation given to the player before the training session.? Through research results, the researcher figured out the exercises followed by the controlling group had an influence on pulse and CPK variables, keeping the difference between the two groups; the experimental and the controlling.? Results gained show that the exercises done by the controlling group formed no significant difference in Lactic acid variation pre and post effort and Creatine due to the nature of exercises, the stress and period of execution. ? The followed method of training and distributing weight - compound exercises increased post - effort Lactic acid concentration level due to the heavy effort and longer training period in addition to an increase in Creatine level for the experimental group as a natural action to face heavy efforts.? The two groups; experimental and controlling remained within near averages in matters of pre - effort Lactic acid ratios and in pulse as a physiological method obtained by the body to get rid of this acid.? There is a clear cut impact of weight compound training in improving the level of some physiological and biochemical changes of young footballers referred to by the researcher.Recommendations : The researcher recommends ;? All trainers and workers in the field of sports to examine physiological and biochemical changes accompanying preparation stages to codify and ensuring athlete's safety.? Performing weight compound training by trainers.? The importance of using field physiological measurement tools in throughout their training to check the impact of training on athlete's body organs to ensure getting the required accommodation as in pulse measurement and Lactic acid tools.? Dependence on physical and bodily training to improve and evaluate the training process.? Reliance on Lactic acid and pulse as a training signal in codifying training weights and estimating bodily weight intense as well as specifying the suitable hospitalization within the light of this variant.? Performing similar studies dealing with other, not researched physiological and biochemical changes.? Performing similar studies to this method on samples of players from different ages.
