The sports field is at the forefront of areas that have witnessed a remarkable
development in recent times, and this development has included all sports and
all kinds. Biomechanical science is considered one of the sciences that dealt
with the study of movement and concerned with the development of the motor
performance of man in general and sports performance in particular. The
basketball game is one of the games that need high skill and at the highest
level to enable the player to achieve good results, especially in the skill of
peaceful correction and the importance of research lies in the analysis The
kinematic of the variable height achieved during the jump and the variable
force projected extracted through the device (Dynafoot) and a comparison
between them, and then looking at their relationship with the relative strength
The research problem was through a weakness in the performance of some
skills, including peaceful correction from the right, and the two researchers
adopted the experimental approach to designing the one group with pre and
post tests for its suitability and the research problem. The completion of field
procedures, the researchers concluded that the nature of the exercises for
using the (Vertimax) device has a positive impact on learning the skill of
peaceful correction from the right side, and the most important
recommendations lie in the use of devices and tools to assist in the training
process that serves the skill of the father Sector correction against the peaceful
and easy to master process such vertimax device and improves the level of
training.

Sports have occupied a prominent place in various parts of the world and have
become an essential part of the lives of many peoples, and sports stars and
heroes are an example for many young people to follow and follow their path.
Thus, the tendencies work to reduce the psychological tension experienced by
the individual in his attempt to reach his goal, as it helps the individual in
adapting the different situations that he interacts with.
So attention was focused on studying the psychological factors that constitute
the greatest weight in creating the integrated player, and psychological
attitudes towards a specific activity are a factor in determining the individual’s
15
behavior with regard to any activity, the student’s desire for a specific subject
that leads to the student’s interaction with that material and achieving benefit
from it, these are Desire is a natural result of the positive psychological trend
towards that subject (Nizar: 2000, p. 135). The researcher decided to conduct a
study on psychological trends towards a football lesson, as psychological trends
have a great role in determining the student’s athletic identity, perhaps if this
research is done in addition New information about the reality of the student

The study aims to identify the level of psychological rigidity of the
football referees in Iraq and the level of knowledge of the arbitral
positions and the accuracy of their decisions and to reveal the
relationship between these variables, as the study was conducted on
a sample consisting of (50) first-class judgment in Baghdad and was
given a measure of psychological hardness to them, and tested them
23
with arbitral positions and the accuracy of decisions, and was used
statistical analysis v 190. Spss, the study found that the level of
psychological rigidity in most dimensions is low, as the results
showed the existence of a relationship between the functioning
mostly between the arbitral positions and the accuracy of the
decision of the referees

The methods of modern play of all kinds do not appear clear during the matches ,but can be
identified through the offensive and defensive tactics for the team as well as through the
movement of players in the stadium , the preparation of the team requires giving a variety of
exercises in clouding the largest number of cases of play for the purpose of facilitating the
process training and programming exercises in line with the mechanism of action in the field ,
it is not the players position that deter
Mines the his movement on the pitch put his ability to decide what to play , the
researcher used the experimental method for its suitability and the nature of the research
experiment was carried out on a sample of the players of Mosul academy for the talent of
soccer (27) player (16-19) years, and were chosen in a deliberate manner and randomly
divided in two groups(excremental and control ) and (10) players for each group , has been
achieved homogeneity in the following variables (age, height , mass), the experimental design
,called the design of the random control group was adopted as pare-and post-test choice the
researchers used the following statistical method (mean, arithmetic, , standard deviation,
variance, deviation, testing ( T) of associated sample ,testing ( T) of independent samples )
the researcher found that he had achieved exercises cases to play implement by the trials
performed by the experimental group were developed in complex skill performance by
comparing result of the tribal and remote tests of the experimental group players , the group
45
did not achieve evolutionary performance in composite skill performance by comparing the
result of tribble remote teste ,the experimental group which carried out the cases to play
exercises ,achieved a better development the control group in the composite skill performance
by comparing the result of the remote teste of the two group the need to pay attention to
exercises in the design of the training curricula, as shown by the result of the search of a clear
improvement in the performance of skill compound and the use of the method of training
high-intensity and the performance of the ideal and difficult performance of the pulse to (180-
190) p/ m in developing the skillful performance of soccer players when using such exercises
as well the standardization of the training curricula according to the scientific functional
indicator mainly to determine loads and interval of interruptions and conduct research and
similar studies on other sports activities and different age group.

The aim of the research was to prepare special exercises for the trunk muscles
of young Romanian wrestlers, As well as to identify the effect of special
exercises for the trunk muscles on the speed of performance of some of the
above-chest throws (kidnapping) for the individuals in the research sample, The
researchers used the experimental approach to its suitability to solve the
research problem, and the design of the two equivalent groups with pre and post
tests were randomly selected, The research sample consisted of young
Romanian wrestlers at the Police Sports Club for the weight group (60, 67, 72)
and by (12) wrestlers, They were randomly divided into two control and
experimental groups, each group (6) wrestlers and (2) wrestlers for each
weight, As well as the use of appropriate means, tools and devices, And a pilot
experiment was conducted, As well as conducting tribal tests, And apply the
experiment, Then conducting the post-test, Then the data was emptied and
statistically processed, And then display, analyze and discuss it, The researchers
concluded that the special exercises for the muscles of the trunk (abdomen,
back) prepared by the researchers after their application have an effective role
in developing the performance speed of the abdominal throwing grabs
62
(kidnapping) among the members of the experimental group, and the curriculum
prepared by the trainer has a positive role in developing the speed of
performance for the grabs Thoracic throwing (abduction) among members of
the control group, as well as the experimental group significantly and clearly
outperforming in the speed of performance of the above-chest throwing grabs
(kidnapping) over the control group.
The researchers recommend the use of special exercises prepared by the
researchers in the training curricula for wrestling teams in the period of special
preparation, as well as the need to use special exercises as they were prepared
according to the precise scientific foundations in determining training loads,
stresses and rest periods between repetitions and groups, as well as focusing on
the use of special exercises during units Training commensurate with the
capabilities and capabilities of the age group

Despite scientific progress in the field of training, more research and studies
must be conducted to arrive at many scientific facts in order to uncover the best
methods and methods to develop each sporting event in an optimal way in trying
to invest human energy to its fullest extent, hence the importance of research
using a method A modern alternative training to the method of training the
heights, which is the use of a training mask that works to reduce the amount of
oxygen, and the importance of this mask in improving and developing the
circulatory and respiratory system by creating an atmosphere similar to the
nature of the heights, and the researchers used the experimental approach to suit
its nature and Research problem and the researchers used the appropriate
devices and tools to search and conduct the exploratory experiment to get to
know the work team and the validity of the devices and tools and conduct the
pre-test to bear the distinct force of speed and the application of exercises and
then conduct the post-test in the same conditions and the researchers used the
79
statistical bag Spss and through it I concluded that the exercises used according
to the mask of altitude training and codify their loads The training led to raising
the level of physical efficiency among young players in the (800) m event

Linear programming instruction is a relatively new experimental area,
especially in the field of physical education and sport. Teachers and
teachers deal with a degree of caution and lack of interest in the
programmed linear education in sport, as well as some difficulties faced
by students in the performance of some complex skills. The importance
of research is to know the effect of programmed linear instruction on
student performance The aim of the current research is to prepare a
curriculum in the method of programmed linear education to teach the
complex skills in the motor sentences on the ground movements in the
technical gymnastic and to identify the effect of this method. Using the
experimental method, the researcher applied the experimental experience
to the experimental group and through the results, the researcher found
that the method of linear programmed instruction in the level of
performance of some skills complex motor sentences on the floor of the
movements of the ground has an effective role in improving the skill
studied and recommended the researcher to conduct research programs
written For other stages of study and the application of the written
program in the lessons of physical education learners feel satisfied and
push them towards better learning and enthusiasm and desire
