Sports vary in the form of contact with the competitor that their rules allow, while others do not allow any form of contact. Taekwondo, a martial art, requires a significant amount of body toughness and strength. The importance of the research lies in finding a new training method related to body toughness exercises that combines two types of training methods (the deep training method for the abdominal and trunk muscles with the functional strength training method that matches the nature of the performance).The aim of the research is to:

Design a training program for physical strength exercises that suits the capabilities of the research sample.
Identify the effect of the training program on the specific muscle strength of Taekwondo players.
The researcher used the experimental method (single group design) to suit it in solving the research problem.The research was applied to a sample of Taekwondo players at the Al-Arabi Sports Club / Baghdad, numbering (12) players. The researcher relied on the electronic device approved by the World Taekwondo Federation (WTF) to calculate the strength of the strike. The training program began to be implemented on Saturday (2/3/2019) and ended on Wednesday (8/5/2019)....and (30) training units distributed over (10) weeks, in which physical toughness was trained by combining the deep muscle training method and functional strength training. Among the most important results reached by the researcher were: -Body strength exercises contributed to developing the specific muscle strength for kicking skills with the foot and hitting with the fist of Taekwondo players.
Body strength exercises contributed to overcoming the weakness in using the fist strength of players to score points

The researcher used a skill test to measure jump shooting. After conducting homogeneity and equivalence, the sample was divided into two groups of equal numbers, one experimental and the other control.The results showed that the suggested exercises to develop jump shooting were more effective in improving the accuracy of the three-point shot than the traditional method. The researcher recommended the need to focus on the exercises suggested by youth basketball coaches due to their importance in developing the three-point shot from jumping.

Football is one of the best team games in the world that can be played by men and women with different levels of experience. Body composition, endurance and balance between anaerobic and aerobic capacity are essential factors in developing players’ performance. The research problem arose from the researcher’s observation that there are some aspects that have not received the required attention, including training players within specific areas of the field using a complex exercise method for physical indicators.And functional because it leads players to the optimal skill performance in the field of football. Despite the fact that most coaches do not resort to allocating their training units to the functional aspect, this study aims to identify the effect of compound exercises in developing physical and functional variables in football among young players aged 19 years and under and advanced players above this age. The researcher used the experimental method because it suits the nature of the research and its problem.He used the appropriate devices and tools for his research. All players were subjected to tests of the variables under study and to the exercise method prepared by the researcher. Pre- and post-tests were conducted for the variables (vertical jump, anaerobic capacity, and maximum oxygen consumption). After that, the differences appeared through the results that the researcher reached through his research. He concluded that the ability to train is not greatly affected in advanced football players.

Most of the lessons presented to students in general follow a general context in teaching offensive skills. Most of them tend to follow the method based on the immediate and direct relationship between the incentive given by the teacher and the response made by the students, and the lesson is limited to the use of very limited means, which may generate monotony in teaching the simple attack skill to students, sometimes reaching a state of boredom. Therefore, we notice some students failing to perform it. The aim has beenThe research aims to identify the effect of the educational curriculum using visual sensory stimuli in developing some visual vision abilities and teaching the skill of simple attack with foil to female students.
