The Effect of Using Medial Longitudinal Arch Supported Insoles on Jumping in Young Football Players

Study Overview
=================
Brief Summary
-----------------
In this study, it was aimed to determine the effect of pressing styles and insoles on jumping performances.

Detailed Description
-----------------
In this clinical study, 30 healthy male football players between the ages of 16-20 will be carried out at Kasımpaşa Sports Club Academy. In the study, the effect of medial longitudinal arch height and the use of insoles on jumping using vertical jump, countermovement jump and drop jump tests will be investigated. Football players; Medial longitudinal arch heights will be measured by applying Foot Posture Index-6 and Navicular Position Test. As a result of these measurements; flat sole, normal sole and high sole will be divided into three groups. These three groups; Vertical jumping, countermovement jumping and drop jumping tests will be applied with the help of portable jumping apparatus and the results will be recorded. These tests will be re-applied to all three groups with a non-personalized, prefabricated insole that supports the medial arch. According to these tests, it will be investigated whether jumping performance depends on medial arch height. It will be evaluated whether there is a change in jumps after the insoles used. The obtained data will be analyzed statistically.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Vertical jump test | It is a test used to determine the jump height in athletes. In our study; The jump starting position for this test will be with the knees flexed at 90 degrees, the head facing forward, the arms positioned freely at the side of the body. While jumping; Upward jumping will be required with a sudden thrust. During this jump, the ankle will be plantar flexed, the knees and hips extended, and the arms will be lifted upwards. During landing, the ankle will contact the ground with dorsiflexion, knees and hips extended, and return to the starting position. 3 repetitions will be done and the highest will be accepted. | 1 day | 
| Countermovement Jump Test | It is a frequently used method to evaluate the capacity of the musculoskeletal system in athletes. It is generally used to monitor the training capacity of athletes through parameters such as jump height, strength, power and speed. The jump start position for this test will be positioned with the knees flexed at 90 degrees, the head facing forward, with the hands on the waist from the sides to restrict the movement of the arms. While jumping; Upward jumping will be required with a sudden thrust. During this jump, the ankle will be plantar flexed, the knees and hips will be extended, and the hands will be at the waist. During landing, the ankle will contact the ground with dorsiflexion, knees and hips extended, and return to the starting position. 3 repetitions will be done and the highest will be accepted. | 1 day | 
| Drop Jump Test | In our study, the starting position for this test will be on a high jump box with the hands at the sides on the waist and in a standing upright position. To initiate the fall movement, participants will be instructed: step out of the box with one foot and try to make the highest jump immediately after contact with the ground. The player will be instructed not to leave the jumping platform and jump out of the box for landing and jumping. The jump box will be 30 cm high. 3 repetitions will be done and the highest will be accepted. Reliability tests were conducted for jumping tests. | 1 day | 
| Navicular position test | The test is done standing up. For whichever foot it will be applied, that foot will be in the back, the other foot will be in front, and the calcaneus of the front foot and the tip of the toe of the back foot will be on the same horizontal plane. In the extremity to be applied, the knee will be kept in a bent position so that it is vertically aligned with the 1st and 2nd finger. In this position, mark the head of the 1st metatarsal bone, the navicular bone, the apex of the medial malleolus, and the dorsal of the Achilles tendon horizontally aligned. First, a line is drawn and extended between the head of the 1st metatarsal bone and the navicular bone. Second, a line is drawn and lengthened between the navicular bone and the Achilles tendon. The angle between these two lines is measured. | 1 day |
