The effectiveness of female students’ participation in sports festivals,
whether they are working in a vacuum or other conditions and factors that interact with it with a planned project with a planned project on a scale for the
effectiveness of participation in the study phase and evaluation in the study
phase, the teacher and phrases, flights of experts and specialists, and follow a
quinquennial scale to correct, Factor analysis was applied to extract the factors
constituting the scale, and after rotating the factors, the researcher reached eight
components that represent a measure of participation effectiveness for students
of the faculties of physical education and sports sciences, and the components
are (behavioral effectiveness, positive effectiveness, responsibility, indifference,
emotional participation, personal efficiency, cognitive effectiveness Work
Motivation). The scale includes (40) statements, as it was found that the highest
score for the scale is (200), the lowest is (40) and the degree of neutrality is
(120)

The research aimed to prepare control exercises according to
disciplines in developing selective attention and some defensive skills among
the members of the research sample, as well as to identify the effect of control
exercises according to disciplines in developing selective attention and some
defensive skills among the members of the research sample. Choosing the
design of the two equal groups with pre and post tests, random selection, as
special exercises are of great importance in the game of volleyball, as they are
among the games that require their practitioners to possess physical, skill and
mental abilities that enable them to perform the match during the competition in
the best case as the close connection between them leads to Raising the level
of the player and achieving victory, and the opposite will affect the other
negatively, so it is necessary to choose special exercises that serve the
technical performance in the training unit, as they express the duty to be
carried out repeatedly, in order to develop the player’s level in all physical and
mental aspects, as a sample was formed. The search of the players of the
Premier League volleyball clubs for the sports season (2020-2021), with a
total of (28) players out of (140) players, and through the lottery, they were
randomly divided into two experimental and control groups, each group (14)
players, as numbers (1-28) were randomly drawn, so numbers (1-14)
represented the experimental group and numbers (15-28) represented The
control group, in addition to using appropriate means, tools and devices, and
the exploratory experiment was conducted, as well as conducting tribal tests for
the two groups, applying special exercises, then conducting post tests for the
two groups, after which the data was unloaded and statistically processed, and
then presented, analyzed and discussed, and the researchers reached several
conclusions They are: The control exercises according to disciplines have a
positive effect on the development of selective attention among the members of
the research sample, and a positive effect on the development of some
specialized defensive skills among the members of the research sample, and
that the selective attention test mediated by the Rehakam system gave
accurate and objective results for the level of reaction speed and control
among the sample members. Research, and the experimental group had an
advantage compared to the control group in developing the specialized
offensive skills of the research sample members. The researchers reached
several recommendations: the need to apply control exercises to elite volleyball
club players, and the need to conduct a continuous laboratory examination of
the players, to determine the level of their true capabilities in reaction speed
capabilities and control the speed of reaction in volleyball, and the use of tests
used in research in the process training, and conducting similar research on
age groups and other research variables

The aim of the research is to identify the values of some biomechanical
variables associated with the performance of the skill of stabbing in the fencing
game in the shutter weapon, as well as measuring the angular work variable of
the stabbed arm and the stabbing accuracy indicator, which depended in its
measurements on the time of execution of the movement coupled with the
success of the movement. The research sample included youth fencing players,
consisting of three players who were chosen in a deliberate way to represent an
advanced level of effectiveness. The technique of recording time indicators of
pressure under feet during the performance stages was adopted using a Frenchmade DynaFoot device to reach digital and instantaneous kinetic values, as well
as fast cameras (210 f / s) to follow the implementation stages accurately. After
agreeing on a test to measure the accuracy of the challenge, the test result was
modified to reach the accuracy index by adopting the FIT Law of Accuracy. Fitt
Law Kinovea kinetic analysis program had a prominent appearance in the
analysis of videos related to skill implementation, and statistical treatments
related to the topic were carried out by means of the SPSS program. The
research came out with a number of results, the most important of which is that
the mechanical work that is necessary to study the parts of the body is required
to be angular because the parts of the body are linked to joints and thus the dear
research results are more logical. Also, the time for the emergence of the force
had a great correlation with the angular work of the arm, which is attributed to a
high accuracy index

Volleyball is one of the most widespread team games in the world, as this
game is witnessing a continuous development in the level of performance of its
players and the results of its matches in attack and defense, which adds training
requirements that must be taken into account in the design of training curricula
and programs. 5) kilograms during exercise.
The aim of the research is to prepare skill exercises by weighting the trunk to
develop pushing force and back crushing, and also to identify the effect of these
exercises. The one with the pre and post test

Management has become a basic process on which all sports activities depend in achieving their goals, and the issue of organizational improvisation is one of the modern topics in the field of management, and it has gained great importance at the beginning of the twentieth century, especially for business organizations, as a result of modern technological developments as well as the rapidly changing environment Which requires the presence of leaders who are able to take the right improvisational decision that transcends routine and advance planning regarding developments and problems in the work environment. Scout work environment using the concept of organizational improvisation in all Iraqi universities. The research community included the scout leaders at the University of Mosul and the University of Tikrit, so the research sample was chosen in a deliberate way, which numbered (18) leaders from the research community, as the main experiment was conducted from (23/5/2022) to (24/6/2022), The researcher used the statistical package (SPSS) to process the statistical data.
