The subject of the research is to examine the effects of training given with internal and external focus on sports performance in young and adolescent girl volleyball players. The aim of this study is to compare the effects of training given with internal and external focus on balance, jumping, hand-eye coordination and flexibility in order to improve sports performance in young and adolescent girl volleyball players.Data will be collected between 01.02.2024-01.01.2025 from individuals who accepted the research in the junior and adolescent girls' volleyball team affiliated with the Malatya Provincial Directorate of the Ministry of Youth and Sports. The individuals in the junior and adolescent girls' volleyball team included in the study by the researchers will be randomly divided into 2 groups.A minimum of 15 people for each 2 groups will be included in the study. Balance, jumping, hand-eye coordination and flexibility training using internal focus for the 1st group. The second group will be given balance, jumping, hand-eye coordination and flexibility training using external focus. In the study, both groups will receive the same exercise training, for the same duration and frequency. Only exercise management guidelines will be differentiated. Balance (static and dynamic), jumping performance, hand-eye coordination and flexibility will be evaluated before and after exercise training.
Sports are activities that improve people's mental and physical characteristics and have multifaceted effects throughout life. These parts should be present in your life from an early age. Volleyball, with influences from different cultures and environments, especially from Turkey's most successful team sports, where women reach large masses. Volleyball is a dynamic team sport that involves very intense movements such as speed, jumping and changing direction. In volleyball, many motor skills need to be coordinated and trained effectively and developed. Basic motor skills in volleyball; Strength, endurance, endurance, coordination, speed and balance are maintained. Neurodevelopmental movement training given to the athlete according to motor learning geometry maximizes the athlete's sporting success and also positively affects their physical, mental and social development. Motor learning is the process by which an individual develops motor skills and performs with a permanent change in performance that is acquired as a function of practice or experience. Instructions and complementary feedback are important influencing factors to support motor learning processes. Storing (re)motoring will be learned immediately, in case of registration, the accepted information will receive instructions on the correct movement system. These instructions typically refer to coordinating body movements, including the order, form, and timing of various limb movements. Instructions that direct the patient's attention to his own movements create an internal focus of attention. A simple change in the wording of instructions can have a significant impact on performance and learning. Transferring the patient's attention to the effects of his movements on the environment (external focus) is achieved through more effective and efficient movements. There are studies in the literature comparing the frequency of internal focus and external focus when training sport-specific motor skills. In a distribution made, child athletes in internal and externally focused feedback groups performed free throw training, and a significant learning advantage was stated in the test results, considering the child athletes receiving externally focused feedback. Another reported that regular externally focused feedback did not increase the accuracy of the table tennis backhand stroke compared to internally focused feedback. In the literature, externally focused feedback was not found in local child athletes and novice athletes, where running was beneficial. Another study in the literature is external feedback in competitive girls' football volleyball players, and according to internal feedback, it is bet that the dunk speed in volleyball has an immediate performance on the athletes. In general, studies in the literature have examined the effects of internal and external tension on volleyball-specific motor performance such as dunk speed and permanence vertical jump performance in girls' volleyball teams on the regime in certain age groups, but no comparison was found between groups. The investigators did not perform these operations but designed them based on the deficiencies in the literature. The research was planned as an experimental study. The study will be carried out in two private sports clubs operating in Malatya, in the little girls' volleyball team between the ages of 7-11 and the adolescent girls' volleyball team between the ages of 12-14. The necessary permission to carry out the study will be obtained from the Malatya Provincial Directorate of the Ministry of Youth and Sports. The study will be carried out in accordance with the principles of the Declaration of Helsinki. By participating in the study, the parents/guardians of the children in the girls' volleyball team will be informed in detail about the study and their written consent will be obtained. Participating children's age, height, weight, age of starting sports, duration of participation in sports (month/day), frequency of participation in sports (day/week) will be questioned with the case report form. Research Sample size: Type I error 0.05 on G-Power 3.1.7 package program (Heinrich-Heine-Universitat, Dusseldorf, Germany); Type II error was calculated by taking 0.2. The power of the test was determined as 0.8. In the study conducted, the minimum number of subjects required to be included in each group was calculated as 15 in order for the difference of 2.3 units regarding total game performance to be found significant. Collection of Data Data will be collected between 01.02.2024-01.01.2025 from individuals who accepted the research in the junior and adolescent girls' volleyball team affiliated with the Malatya Provincial Directorate of the Ministry of Youth and Sports. The individuals in the junior and adolescent girls' volleyball team included in the study by the researchers will be randomly divided into 2 groups. Balance, jumping, hand-eye coordination and flexibility training using internal focus for the 1st group. The second group will be given balance, jumping, hand-eye coordination and flexibility training using external focus. In the study, both groups will receive the same exercise training, for the same duration and frequency. Only exercise management guidelines will be differentiated. Balance (static and dynamic), jumping performance, hand-eye coordination and flexibility will be evaluated before and after exercise training. Reviews The equipment to be used for evaluations will be covered by the researcher. Participating children's age, height, weight, age of starting sports, duration of participation in sports (month/day), frequency of participation in sports (day/week) will be questioned with the case report form. Height will be measured with a stadiometer and weight with a 0.5 kg precision scale. Jump evaluation will be made using the Vertical Jump Test. It is a test with a very high reliability coefficient (rxy=0.97) for determining the athlete's jumping force. The athlete reaches the maximum point he can reach with one arm in front of the platform to be tested and the distance is determined. The difference between this point where the athlete can reach and the highest point he can reach by jumping is determined and the height is recorded in cm. The test must be repeated twice to determine the best score. Flamingo balance test will be used in static balance evaluation, and y balance test will be used in dynamic balance evaluation. Flamingo balance test is used to measure static balance. For this test, a balance board made in standard sizes determined by Eurofit is used. The balance board is made by mounting two wooden beams, 2 cm wide and 15 cm long, spaced apart and perpendicularly, under two wooden beams that are 4 cm thick, 3 cm wide and 30 cm long. The participants' ability to stand on one leg on the balance board is tested. The participant steps on the balance board with one foot and bends the knee while holding the free foot with the hand on the same side. Meanwhile, his free hand is supported by the tester. As soon as the participant feels that he has regained his balance, he releases the tester's hand and the stopwatch is started at that moment. If the held foot is released or if the balance is disturbed and the foot leaves the balance board, the stopwatch is stopped and the time is recorded. If the person being tested does not lose balance for 60 seconds, the test is terminated. Y balance test is a dynamic test performed in the standing position on one leg. It examines how the core area and both extremities work under body weight. Before the test, individuals remove their shoes and stand on the foot plate in the center of the Y Balance Test area. Individuals are then instructed to maintain a single-leg stance while reaching as far as possible with the opposite leg and return to the starting position on the middle 22 platform without losing balance. In the test, individuals are asked to reach the maximum distance in 3 directions (anterior, posteromedial and posterolateral), allowing 3 attempts for each leg. The maximum reach distance is recorded for each consecutive attempt. The Standard Sit-Reach Test will be used to evaluate the flexibility of the back and leg. The child is seated on the ground on a flat surface, allowed to rest the soles of his bare feet flat on the test stand, then his body is extended forward as far as he can reach, and he is asked to wait for a second or two at the last point with the arms and fingers tense and straight, and after two attempts, he It is recorded well. Wall Catch Coordination Test will be used to evaluate hand eye coordination. The participant stands facing the wall at a distance of 3 meters. The ball is thrown from bottom to top by keeping the shoulder stable, provided that it is caught with the throwing hand. After a certain number of trials, the other hand is tested. Scoring of successful shots is done the same way for both hands. To assist in evaluating the results, the score of the participant's preferred side should be recorded. A tennis or baseball ball can be used to perform the test. treatments Exercises Exercise 1: Hands-free vertical jump (the movement of an individual jumping from a certain point and then jumping back to the same point) 3 sets of 10 repetitions / 1-2 minutes of rest between each set Internal Focus Instructions: With participants hands free, jump to the highest point participants can without disturbing participants body balance.
