Compound races are among the most enjoyable and strongest races in athletics due to their multiplicity and diversity. Also, this race is one of the races that need all physical fitness elements and strongly so that the contestant can excel in this race as it occupies a special place in the field and international and Olympic track and field competitions program, so the vehicle player needs to Biological characteristics and physical abilities as a result of the different and varied requirements of the races that make up this race, as it is characterized by a wide difference in the nature of performance, as the sprint and running races differ from the jump and throw races. (Al-Jabali, 1994, p. 113)
And through the researcher's follow-up of the practical lessons of the fourth stage, the students of this activity, she noticed the difficulty of continuing to perform the activities of the three different and varied groups in running, throwing and jumping as a result of the weakness of some of their physical abilities. The researcher decided to study this phenomenon and find appropriate solutions to it through the aim of the study in finding the relationship between some physical abilities and the result of the effectiveness of the seventh among the members of the research sample (female students) for the first day.
The researcher used the descriptive one-group approach. The research sample was identified from the fourth stage students. By conducting some pre-physical tests and after obtaining the statistical results, the researcher concluded that there is a significant correlation between the effectiveness of the long jump and the effectiveness of pushing weight and physical abilities. There was no significant statistical significance between the effectiveness of running the 100m hurdles and the 200m efficiency and physical abilities.
Key words: compound races (sevens) - physical aptitude

The progress made in biotechnology research, which refers to the technical application of living systems, is an indicator in itself of the development of all scientific fields. This has contributed to solving many problems in the field of sport, which is one of the areas affected by the progress of biological sciences. This has in turn helped many researchers to see how these genes affect the level of achievement of the players and the differences between them according to these genes Humans in general and players differ in particular according to the genetic code or DNA.
The training of athletics activities depends on the development of scientific and training programs to develop the level of sports and reach to the upper levels, and each efficiency specifications and requirements, including the events run intermediate distances, including the running 1500 meters, which need to develop some of their own energy systems for adaptation Physiological of the organic organs to perform and bear the effort during the race in terms of the latticet threshold, which means the accumulation of lactic more than disposal, which in turn is the decisive factor of the level of performance as delayed delay gives a greater time of performance requires the racers of the race 1500 m from Delay the accumulation of lactic acid, which helps for continuous performance for a longer period while maintaining the speed of performance before reaching the point of refraction. Therefore, delaying access to the lactic threshold is an indication of the development of biochemical and physical, which must be the training of the trainer in the field of training for individual games, Above, the objectives of the research were formulated as follows:
- Identify the forms of the MCT1 gene, which is enjoyed by the racers of the 1500 meters youth.
- Recognition of the effect of lactic acid training in the development of achievement of 1500 m young people and classified according to alleles gene (MCT1.)

The assignment method is considered one of the modern learning methods in the field of teaching motor skills in sports activities, as it is an interactive educational method through an educational curriculum to achieve specific goals. The importance lies in developing a proposed educational curriculum according to the assignment method in learning some offensive skills in the hands of workers and specialists in the game. Fencing, to develop the educational aspect and prepare educational units in the style of assignments in learning some offensive skills with the epee weapon for students. The problem is that the researcher noticed the level of the students, as he is a specialist in the game, that there is a weakness in their level of learning in performing some offensive skills with the epee weapon. This is due to the teachers’ use of non-modern educational methods in teaching offensive skills that do not give the student a major role in improving his skill level. The purpose of the study is to identify the impact of the proposed educational curriculum using the assignment method in learning some offensive skills with the epee weapon in fencing for students. And the extent of the impact of the curriculum on the experimental group in these skills, and is there a positive impact of the proposed educational curriculum? The researcher identified the population as students of the third stage / College of Physical Education and Sports Sciences - Al-Qadisiyah University for the academic year (2020), numbering (92) students, and the sample. The research consists of two sections that were randomly selected by lottery. The number of members of the sample became (36) students, who were distributed into two groups (control and experimental), and the number of students in one group was (18) students. This was after failing students, club players, teachers, and students who were absent from the educational units before starting the educational curriculum were excluded. Thus, the percentage of the sample reached (39.130%) from the original population. The experimental group used the educational curriculum using the assignment method, and the control group used the traditional method of the subject teacher. Conducting homogeneity among the groups as a whole in the variables (height, body mass, and age) and parity between them in the variables under study. All field procedures were carried out, including measurements and tests, through which the necessary data was collected and then the appropriate statistics were conducted and classified in the form of tables, analyzed and discussed, and appropriate conclusions were drawn.
