Brief Summary

In the realm of sports performance, particularly in disciplines demanding explosive lower-body strength and agility, such as basketball, an athlete's ability to execute powerful and high-reaching jumps plays a pivotal role. Optimal lower-extremity flexibility, particularly in the hamstrings, is crucial for achieving maximum vertical jump height. Hamstring shortness, characterized by limited flexibility and reduced muscle extensibility, is frequently observed among athletes and has been linked to compromised jump performance.

Outcome Measures

Primary Outcomes (6)

• Goniometric Measurement

  The individual who will participate in the evaluation is placed in the supine position. After taking the ankle of the participant's leg, which we will measure, to neutral, the participant passively flexes the leg at the hip. When the participant feels resistance during this movement, when pain sensation occurs and at the last point where the knee starts to bend, the measurement is taken with a goniometer. In the goniometric measurement, the pivot point is based on the trochanter major and the fixed arm is parallel to the trunk. If a value below 80 degrees is obtained as a result of the measurement, it is seen that hamstring shortness is present in this person.

  day 1

• sit and reach

  Individuals who will participate in the assessment are asked to remove their shoes and socks. The individuals to be evaluated sit in a long sitting position with the soles of their feet in full contact with the measuring board. The participant is asked to push the iron bar by slowly reaching towards his/her toes with both hands without bending his/her knees. The point on the pushed bar where the individual can reach the maximum distance without bending his/her knees is taken as a criterion. If the iron bar is below 30 cm, it shows that the hamstring muscle is short and the test is positive

  day 1

• Y Balance Test

  In order to apply the Y balance test, a large letter Y is taped to the ground on a flat surface so that the angle between the front and back directions is 135 degrees and the angle between the two back sides is 90 degrees. The participant to be tested is asked to move to the center of the line. The participant is instructed that while balancing on one foot, he/she should reach anteriorly, posterolaterally and posteromedially with the other foot and keep his/her weight on the stable foot. . For score calculation, the distance lengths in three directions obtained with the participant's previously measured leg length are summed, divided by 3 times and multiplied by 100 to obtain the score

  day 1

• Popliteal Angle Measurement (Holt Method)

  While the person to be evaluated is lying on his/her back, the knee and hip are flexed 90 degrees. After assuming this position, the individual is asked to extend the knee until a resistance is encountered. The angle between the vertical axis of the knee and the last point reached in the movement is measured and this angle is expected to be 0-10 degrees in normal individuals. If full extension cannot be performed, hamstring shortness is determined

  day 1

• vertical jump Height

  The optojump system will be used in this study as a jumping power measurement tool. In the measurements, the vertical jump height was recorded with the optoJump system and the software of this system (Microgate, Bolzano, Italy). The measurement of the vertical jump distance in centimeters is done by means of two bars in the OptoJump system with sensors that detect movement.

  day 1

• The duration of the jump (milliseconds)

  The optojump system will be used in this study as a jumping power measurement tool. The duration of the jump (milliseconds) is also included in determining the jump distance.
