‫ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ‬ ‫ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ‬ Research Introduction:
The sport of wrestling has become based on many biomechanics, anatomy, physiology, sports psychology , training and so on related to human motor activity for the purpose of upgrading the sport of wrestling from different sub-districts.
(16 : 6) The sport of wrestling is one of the sports that contain many currents, whether national or defensive.It is a struggle between two individuals who try to achieve control and win over each other through the use of special handles and throws that aim to achieve touching the shoulders or points within the framework of international rules and laws.(15: 21) Wrestling is also one of the violent sports that training leads to functional changes to the vital organs of the world , and no sports coach can raise the level of the player unless he is available witha physiological mattress that helpshim in evaluating various functional changes, whether this change is temporary or permanent.The wrestler needs the anaerobic ability when executing the wrestling and the misdirected throws, the moment of defense, the moment of escape from an imminent movement, or when pressing on the competitor.(16: 244) The sport of wrestling is considered to be the rest of the games and other sports, as it consists ofa set of skills and basic principles that the wrestler must know and train to continue and develop, including the use of modern tools and theories in the field of the game and according to the physiological variables resulting from the difference in individual differences between players.(3: 2) Issam Helmy (2015) confirms that the performance I see is closely related to the physical and motor capabilities of the individual, as the mastery of the performance depends on the extent to which the individual develops this performance from the physical and motor capabilities of the individual, such as biting strength, flexibility, speed and agility.The level of performance I see is often measured by the extent to which the individual acquires these special physical and motor qualities.(8 : 171) Alaa Mohammed Kenawy (2005) confirms that the full mastery of motor skill is based on reaching the highest levels of sports for them, reaching the level of physical qualities of the wrestler, which are characteristic of his moral and voluntary characteristics, he will not achieve the results required of him unless this is linked to the full mastery of all technical movements of wrestling.(9 : ٣٤) MohammedAl-Aishi (1997) explains that the skill preparation for wrestling aims to master the wrestler's basic skills and movements that are commensurate with his physical and functional abilities and aptitudes so that he is able to implement them successfully under the changing circumstances of the game.(17: 46) Most experts in the field of wrestling, such as Massad Ali Mahmoud (2003), Mohammed Reda Al-Ruby (2008) andAlaa Mohammed Kenawi (2005), and others agree to divide wrestling skills into seven basic skills according to the classification of the American Federation of Wrestling and supported by the Egyptian Federation, which contains: Bosition of body Gladiator Motion Changing the level of the body Lifting up Back step Backarching The seven core skills are used as a general framework for the education and training of wrestling with the aim of improving the player's physical, functional and technical abilities and placing him on the ladder of achievement and championship.(16 : 1) , ( 12:30),( 9:39) The researcher believes that the wrestler strongly needs the skill of arching backwards, including the skill under discussion, which is Suplex, as a defense for the front center, as it is no less important than the rest of the motor skills, and even increases its importance in the conflict according to the different playing situations, especially during the conflict from above, where its importance is limited to the payment area on the zone (Zone) of the competitor, where its importance is that if it is done correctly and meets the conditions of the correct technical snap Grand technic, which is that the competitor loses contact with the ground , and takes a full course in the air , and falls directly on the shoulders, so the attacking player is entitled to (5) deserved technical points, and it may reach the point until the attacking player finishes the round by winning.The suplex movement is one of the very common movements in wrestling, where wrestlers begin to face each other face to face, and then the attacker grabs and hangs from the bottom of the opponent's armpit while making a net in front of the opponent's chest and making a back arch, so that the opponent's body is inverted around his vertical axis above the attacker, and the attacker falls back on his back , using his body weight to also hit his opponent on his back strongly in the rug.( 25) The suplex movement is considered one of the most effective offensive skills, and its importance lies in the method of holding as a kind of deception or evasion because of its various forms of entry into the body of the competitor.It can be a way to hijack the movements of the opponent or enter the middle.It is also an effective offensive means to obtain technical superiority and thus a decisive way to end the round by winning.(2 : 56) The effective implementation of this skill requires the integration of strength, balance, speed and flexibility.By informing the researcher of the specialized scientific references to determine the basic muscle groups working in the performance of curvature, the researcher extracted the basic muscle group, which is the group of muscles of the center, which is represented in the front and lateral abdominal muscles as well as the back muscles.117 Sharkey (1990) adds that it is necessary to train the working muscles of the wrestler in a special training according to how to use them in the practicing activity, and stresses the importance of linking the training to the form of the skill to be developed.(23: 35) Mohammed Al-Ruby (2004) believes that the group of arch movements is an important and essential successor in the artistic and skillful performance of Roman wrestling, and the wrestler who is good at implementing that group with high skill can surprise competition and achieve early superiority over it.10 Richardson CA, Jull GA (1995) show that the lumbar, pelvic, and femoral complex (LPHC) is an area of the body that has tremendous influence on the structures above and below it.The LPHC contains between (29-35)muscles that attach to the lumbar spine or pelvis and the LPHC is directly connected to both the lower limbs and the upper limbs of the body.For this reason, a defect in the lower and upper extremities can lead to a defect in the LPHC and vice versa.Collectively, these structures serve to stabilize muscle fibromuscular (LPHC) tissues such as the biceps femoris, the medial hamstring complex, and the rectus femoris.These bones and joints have a functional effect on LPHC joint mobility There are a number of muscles in the upper and lower extremities whose function may be related and have an effect on LPHC As with all muscles, it is important to restore and maintain the normal range of motion and strength, as well as eliminate any muscle inhibition to ensure that the joints function optimally.(22 : 127) The American Society for Rheumatology has included in its recommendations regarding resistance training since 1998 that resistance training leads to muscle contraction against external resistors with the expectation of an increase in strength, biting tone and endurance.External resistance may be constant (free weights) or variable resistance (rubber cord) or any body that leads to muscle contraction.(15: 4) In the construction of training for the use of resistance exercises, the principle of gradual increase is fully adopted.The researcher has noticed through his work that there is a deficiency and slow pace in the performance of some Suplex movements, despite the importance of these movements, whether in training or competitions, which reflects negatively on the outcome of the wrestler, and through access to the Global Information Network (the Internet) and what was made available to the researcher from previous studies and within the limits of the researcher's knowledge of the absence of Arab studies that dealt with the movements of Suplex in the sport of wrestling, which prompted the researcher to conduct this study.
He also noted that there is a shortage and decline in the level of wrestlers to use Suplex movements during training, in addition to the need of second stage wrestlers (cubs) to develop some elements of physical fitness for the muscles of the lumbar, pelvis and hip complex (LPHC), which contributes to improving their skill level and given the importance of the element of strength, flexibility and skill performance, in addition to the novelty of the proposed training method, which is the flexible resistance method and its impact.
Therefore, the researcher believes that he proposes to design a training program with flexible resistors for the muscles of the lumbar, pelvic and hip complex (LPHC) and to know its impact on the improvement of the level of performance of Suplex movements among wrestling players in the second stage (cubs).The importance of the study: The importance of this research and the need for it are highlighted in the following: Scientific importance: The scientific importance of the research is clear as it is an attempt to contribute to: -1-Knowing the training of flexible resistors to achieve some of the goals of the Roman wrestling sport.

The attention of Romanian wrestling coaches is focused on the correct technical performance of the technical skills of the Sobles movements.

The Aim of the Research:
The research aims to identify the impact of elastic resistance training on the lPHC muscle group and improve the level of skill diseases of SUPLEX movements for Cub Wrestlers Phase II (Cadets).* Research hypotheses: In light ofthe current research, the researcher assumes the following: 1-There are statistically significant differences between the averages of pre and post measurements in the level of skill performance of the SUPLUS movements in the experimental research group in favor of post measurement.
2-There are statistically significant differences between the averages of pre and post measurements in the level of skill performance of the SUPLUS movements in the control research group in favor of post measurement.
3-There are statistically significant differences between the mean of the two dimensional measurements in the experimental and control research groups in the level of skill performance of the substitution movements in favor of the experimental group.Terms used in the research : Resistors: It is the system that is done through the development of biting force using exercises for a special function that is performed against rubber ropes, geese, sandwiches, or variable resistance.( 203)

Lumbar, Pelvic and Hip Complex (LPHC):
It is an area of the body that has a tremendous impact on the structures above and below it, (LPHC) contains between (29 and 35) muscles that attach to the lumbar spine or pelvis, and (LPHC) is directly connected to both the lower limbs and the upper limbs of the body.For this reason, a defect in the lower and upper extremities can lead to a defect in the LPHC and vice versa.135 Wrestling.
It is a fight between two wrestlers during three rounds of two minutes each.The match ends before the specified time when the shoulders are fixed, multiple errors or exclusion.If it ends and none of the wrestlers gets three points, additional time is played.4:39 Suplex Movement: The Suplus movement consists of a single wrestler picking his opponent by the waist and then using a large portion of his body weight to forcefully push the opponent down on the mat back and almost all of the suplexes make the attacker come down to the ground as well with the opponent landing on his back.

Stage 2 Wrestlers (Cadets):
It is an age stage in the sport of wrestling that includes cub wrestlers from the age of (16-17) years andless than 15 years.A medical certificate and the consent of the guardian are required.(Procedural definition) Previous studies: 1-A study by Abu Sabri Muhammad (2022) (4) entitled The Impact of Posterior Bowing Exercises on the Deviations of the Cervical Spine of Wrestling Sports Players.The study aimed to identify the impact of posterior bowing exercises on the deviations of the cervical spine of wrestling sports players.The size of the core sample was (10) wrestlers.The exploratory sample also reported (2) wrestlers from the Mahalla Hunting Club and those enrolled in the Egyptian Wrestling Federation.The researcher used the experimental approach.The most important results of the study were the absence of a tangible change in the impact of posterior bowing exercises on the anterior deviations of the spine, the absence of a tangible change in the impact of posterior bowing exercises on the lateral deviations of the spine, the interest in ration of training and the correct guidance of loads during the use of posterior bowing exercises.

-Recording the names of each group in the data registration form (Attachment 2) -Conducting scientific transactions for the tests used.
• Scientific transactions of tests: First: Validity coefficient: The researcher verified the validity of the tests "under research" using experimental validity (differentiation), by applying the tests "under research" to the survey sample of (10) players, and they were divided into two groups, one of which is distinctive and (5) players and the other is an undistinguished sample of ( 5) players with the same specifications, but they do not practice an activity that shows this in Table (5).5) that the value of (T) calculated is greater than the value of ( T) tabular, as the value of (T) calculated was limited to (2.501, 8.382), which indicates the existence of statistically significant differences between the distinctive and nondistinctive group in favor of the distinctive group in the skill tests of the SUPLUS movements in question at a significance level of (0.05), which indicates the validity of the tests in question.

1-Stability coefficient: -
The researcher calculated the stability of the skill tests of the Sobles movements through the application and then reapplied to the unmarked group of (5) players after a period of time of (4) days to ensure the end of the impact of fatigue from the first performance and then calculated the difference between the two medians and also found the correlation coefficients between the degrees of application and the degrees of reapplication.6) that there is a strong correlation between the first and second applications, where the value of the correlation coefficient was limited to (-0.218: 0.763) and the calculated value ( t) was greater than its tabular value at a significant level (0.05), which indicates the stability of the physical tests under consideration.

Proposed Program (Attachment4):
The researcher developed the proposed program using flexible resistance exercises based on previous studies such as the study of Hamada Mansour Hamada (2022AD) (5), Abdulhadi Hassan Abdulhadi (2022AD) (7), Ali Salman Abdul Tarafi, Muhammad Khalid (2019AD) (10).In addition, the views of a number of specialists in the field of wrestling education and training were used (Annex 1).Accordingly, the content of the training modules was modified until it became final.

Table (7) Percentage of experts' agreement on appropriate tests to measure research variables (n=5)
It is clear from Table ( 7) that all exercises have achieved a percentage ranging from (80%: 100%), which means that they are on a high degree of honesty, and thus the researcher was able to identify the proposed training exercises where the researcher accepted (80%) for approval, and thus the exercises and trainings were determined according to the opinions of experts and then placed in training units using exercises on a muscle group (lPHC), and the trainings were distributed on the training units and became in its final form (Attachment4). -

Overall programme objective
The program aims to identify the impact of flexible resistance training on the lPHC muscle group and its impact on improving the level of skill performance of SUPLEX movements for Cub Wrestlers Phase II (Cadets).
- In order to achieve the goal of the research and to achieve its hypotheses and within the limits of the researcher's data reached through the methodology used, the research sample, the selected data collection tools and the statistical analysis used, the researcher presents the research hypotheses and discusses them.

First : Presentation and discussion of the results and interpretation of the first hypothesis:
Presentation and discussion of the results and interpretation of the first hypothesis, which states that there are statisticallysignificant differences between the averages of preand post measurements in the level of skill performance of the Sobles movements in the experimental research group in favor of post measurement.Table T value at a significant level of 0.05 = 1.85 It is clear from Table (10) that there are statistically significant differences at a significant level (0.05) between the pre and post measurements in the experimental research group in the level of skill performance of the Sobles movements, where the calculated value (T) ranges between(3.21: 7.14), which are values greater than the tabular value (T), and the percentage improvements ranged between(56.57%: 72.89%).(1) that the rates of improvement and the size of the impact between the pre-and postmeasurement of the experimental research group in the level of skill performance of the Sobles movements under study in favor of postmeasurement, and the researcher attributes this improvement and impact to the proposed training using flexible resistors on the lPHC muscle group, where the movement of encircling the middle with the arms and arching backward got the highest improvement rate of (72.89%) and a high impact size of (3.7), while the movement of encircling the arms and middle and arching backward got an improvement rate of (71).68%) with a high impact value of (4.1), and the movement of encircling the arm and middle and arching backward got an improvement rate of (71.84%) with a high impact value of (3.0), and the movement of the performance of the bridge skill got an improvement rate of (68.12%) with a high impact value of (3.6), and the reverse center grip movement and backward curvature got an improvement rate of (66.08%) with a high impact value of (2.3), and the movement of holding the neck from the top and passing through the armpit and arching also got an improvement rate of (56.87%) with a high impact value of (2.2).
The researcher also attributed these statistically significant differences for the players of the experimental group in the skill variables to the positive impact of the proposed training using elastic resistors on the lumbar, hip and thigh muscles group (lPHC), and the various training using elastic resistors that contributed to the development of the physical capacity of the working muscles under study, through what the player was exposed to as a result of the proposed exercises that lead to the same kinetic path of the soap movements in Roman wrestling.

Owais
Al-Jabali (2000) indicates that modern sports training aims to develop the general and special physical abilities required by the practicing sports activity, in addition to focusing those special physical abilities in order to activate and develop the motor performance of that activity, which is reflected in the improvement and development of different playing strategies.(11: 171) This is in line with the study of Ihab Sabry Mohamed (2022), which aimed to identify the impact of posterior bowing exercises on the deviations of the cervical vertebrae of the spine of wrestling athletes.The most important results of this study showed interest in rationing training and correct guidance of loads during the use of posterior bowing exercises because of their positive impact on skill performance.
Mohammed Al-Ruby (2004) points out the need for trainers and specialists in the field of wrestling training to pay attention to the range of movements of the skill of curving backwards, because of the importance of these movements for the wrestler.(12: 10) This is in line with the study of Hamada MansourHamada (2022), which aimed to identify the impact of strength fitness exercises on the effectiveness of the performance of some curving movements behind wrestlers, and the most important results of the application of the training program using strength training for its positive impact on the skills of curving and the effectiveness of the skill performance of wrestling players and applied to similar samples , the need for coaches to develop strength training and put it in the form of gradually difficult training in terms of composition, making it more interesting and similar to what happens in matches.( 5) Thus, the validity of the first hypothesis is achieved, which states that "there are statistically significant differences between the averages of pre and post measurements in the level of skill performance of the Sobles movements in the experimental research group in favor of post measurement."-Presentation and discussion of the results of the second hypothesis: Which states that there are statistically significant differences between the averages of pre and post measurements in the level of skill performance of the Sobles movements in the control research group in favor of post measurement.(2) that the rates of improvement and the size of the impact between the pre-and post-measurement of the control research group in the level of skill performance of the SUPLUS movements under discussion in favor of postmeasurement, and the researcher attributes this improvement and impact to the traditional exercises followed within the club where the movement of encircling the arm and middle and arching backward got the highest improvement rate of (29).44%) with a high impact volume of (0.91), while the movement of encircling the center with thearms and arching backwards obtained an improvement rate of (28).44%) with a high impact value of (1.12), and the movement of the performance of the bridge skill obtained an improvement rate of (26.95%) with a high impact value of (1.2), and the reverse center grip movement and backward curvature got an improvement rate of (24.67%) with a medium impact size of (0.62), and the movement of encircling the arms and middle and arching backward obtained an improvementof (22.86%) with a medium impact size of (0.71), and the movement of the neck grip from the top and passing through the armpit and arch also obtained an improvement of (18.32%) with a medium impact size of (0.28).The researcher returns these statistically significant differences for the players of the control group in the variables of the skill movements of the Sobles skill to the regularity of the traditional training process that contributed to the development of the physical and skill capabilities of the research sample through the basic training to which the player was exposed.This is in line with the study of Mahmoud Al-Saeed Al-Rawi (2016), which aimed to develop a set of exercises and identify the extent of their impact on the physical abilities of wrestlers, the level of nervous stress and the improvement in the level of skill performance of wrestlers.Regularity in traditional training has a positive impact on the development of physical variables, which led to a high rate of improvement in the skill level of the control group.
(14) Thus, the validity of the second hypothesis is achieved, which states that "there are statistically significant differences between the averages of pre and post measurements in the level of skill performance of the Sobles movements in the control research group in favor of post measurement."Presentation and discussion of the results of the third hypothesis: Which states that there are statistically significant differences between the average of the two dimensional measurements in the experimental and control research groups in the level of skill performance of the SUPLUS movements in favor of the experimental group.

Schedule-14
Indicator of differences and percentages of improvement between the two dimensional measures in the experimental and control research groups in the level of skill performance of the SUPLUS movements (n = 20)  14) that there are statistically significant differences at a significance level of 0.05 between the two dimensional measures in the experimental and control research groups in the level of skill performance of the Sobles movements in favor of the post-measurement of the experimental group, where the calculated value of (T) ranged between (2.78: 7.45), which are values greater than the tabular value of (T), and the percentages of improvement ranged between(22.53%: 28.50%).improvement rate of (25).71%) with a high impact value of (1.58), and the movement of encircling the arm and middle and arching backward got an improvementof (25.69%) with a high impact value of (1.12), and the reverse center grip movement and backward curvature obtained an improvement rate of (24.93%) with a medium impact size of (0.65), and the movement of holding the neck from the top and passing through the armpit and arching got an improvement of (24.57%) with a medium impact size of (0.78), and the movement of the performance of the bridge skill obtained an improvement rate of (23.53%) with a medium impact size of (0.92).
The researcher attributes the high rate of improvement of the experimental group from the control group to the regularity of the traditional exercises in addition to the proposed training using elastic resistors on the lumbar, hip and thigh muscles group (lPHC), with the application of the training load variables during the unit, which led to the development of the physical aspects of the working muscle group to implement the SUPLUS movements, which in turn was reflected in the improvement in the skill performance of the movements, as the flexible resistors training contributes to improving the level of performance to a greater extent in the experimental group from the control group as a result of developing muscular performance in line with the motor path of the skill.

that training is related to the fact that the best way to develop performance is through training in a manner that is very similar to the style of the competition itself, and the more specific the training, the better the training return during the competition, as this principle can be observed in a large number of sports skills and match conditions.(24 : 48) This is in line with the study of Mahmoud Al-Saeed Al-Rawi (2016), which aimed to develop a set of platts exercises and identify the extent of their impact on the physical abilities of wrestlers and the level of nervous stress and improve the level of performance I see for the skill of the front center.Its most important results showed that the training program has a positive impact on improving obese and skilled variables in addition to improving the psychological aspect and otherwise reducing nervous stress, which improves the level of skill performance of wrestlers.( 14) It is also consistent with the study of Ali Salman, Muhammad Khalid (2019), which aimed to prepare special exercises using training means suitable for the research sample, to identify the impact of special exercises in the development of special flexibility, and to identify the impact of special exercises in the development of skill performance in wrestling.The most important results of the study were that the designed training means proved their capabilities in the development of special flexibility.These test methods are characterized by the ease of application to them as well as giving a result in the improvement of these skills.10 It is also consistent with the study of Abdulhadi Hassan Abdulhadi (2022), which aimed to find out the impact of flexible resistance training on some of the physical variables of the Romanian wrestler.The most important results of the study were that the flexible component training applied to the experimental sample under study is a significant improvement in the physical variables (bearing speed, bearing force, bearing performance, bearing antenna, transitional speed, maximum speed, distinctive force).The results of the flexible component training applied to the experimental sample also resulted in a significant improvement in functional (respiratory) and skill responses.(7) Thus, the validity of the third hypothesis is achieved, which states that " there are statistically significant differences between the average of the two dimensional measurements in the experimental and control research groups in the level of skill performance of the Sobolus movements in favor of the experimental group."

Conclusions and Recommendations Conclusions
In light of the results of the study, the researcher reached the following conclusions: 1-There are statistically significant differences between the proposed program in the flexible resistance method in the level of performance of Mahari for SUPLEX movements in favor of the post-measurement of the experimental group.

2-
The control group showed a positive impact on the variables under consideration in order to be regular in the training.

3-
The proposed flexible resistance training program had a positive effect on the lumbar, hip and thigh muscles group (lPHC).

4-
Resistance training has a great impact on developing the strength and flexibility of the muscles of the wrestlers' suppulatory movements.

5-
During the match, the opponent places an inverted and vertical opponent over the attacker, and the attacker falls back on his back, using his body weight to also hit his opponent on his back hard in the mat.

6-
The use of new tools in the training of wrestlers, which are commensurate with the form of skill performance used, has led to a change in the form of muscle contractions, which contributes to the physical direction and skills under study by increasing the strength, muscle tone and flexibility of the wrestler.

5-
The need for trainers to pay attention to the use of flexible resistance within special training programs in the sport of wrestling, because of its positive impact on raising the level of performance of the skill of SUPLEX.

6-
The use of posterior curvature exercises is under study and in accordance with the appropriate age group.
