In such a way that the selection of participants was completely based on chance and probability and every participant had the same chance to enter the sample. The main factor for us was that each participant had an equal chance of being placed in each group. Then, with the lottery method, the names of the people were written on paper and placed in a container, and someone other than the researchers randomly picked the names, and the names that were the first to leave the intervention group and the rest of the control group. In the randomization process, the researchers had no involvement and this work was done by an uninformed person. 2-3 Limited Cervical Range of Motion and Hamstring Muscle Shortness. Intervention 1: Intervention Group 1:Self-myofascial release of the hamstring muscles and plantar fascia was performed using a foam roller and massage ball by the participant. The participant sat on the floor with the foam roller placed under the posterior part of both thighs. By shifting their body weight onto the foam roller, they slowly rolled back and forth along the hamstrings. This movement was performed for 2 minutes, in 3 sets.Next, the participant sat on a chair and placed a massage ball under the sole of the foot. By applying slight pressure, they rolled the foot slowly back and forth over the ball. This exercise was also performed for 2 minutes, in 3 sets for each foot. Intervention 2: Intervention Group2:The participant lay supine on the floor while the researcher passively lifted one leg upward, keeping the knee extended, until the participant reported a sensation of stretch accompanied by mild discomfort. The position was held for 30 seconds and repeated three times for each leg.Next, while still lying on the floor, the participant was instructed to place a resistance band around the ball of the foot and actively pull it toward themselves until a stretch was felt in the plantar aspect of the foot. This stretch was also held for 30 seconds and performed in 3 sets for each foot. Intervention 3: Control group: No intervention was applied. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is According to the publication of the article, a decision will be made on this matter

Control group: No intervention was applied Neck range of motion including flexion, extension, lateral flexion and rotation. Timepoint: Before the test and after the test after doing 6 weeks of training. Method of measurement: Using the Measure Angles Bubble Level protractor and protractor version 3.99.92 application on the iPhone 13 Pro Max smartphone. Neck proprioception. Timepoint: Before and immediately after intervention. Method of measurement: Angle reconstruction error method to check the proprioceptive condition using laser pen and graduated plate. Static Balance. Timepoint: Before and immediately after intervention. Method of measurement: Static balance was assessed using the Single-Leg Stance Test with Eyes Closed. In this test, the participant stands on their dominant leg on a flat surface, lifts the opposite foot off the ground, and closes their eyes. The duration for which balance is maintained without losing posture is recorded as an indicator of static balance. Dynamic balance. Timepoint: Before and immediately after intervention. Method of measurement: Dynamic balance was assessed using the Y-Balance Test. In this test, the participant stands on one leg (the stance leg) while reaching the other leg in three directions: anterior, posteromedial, and posterolateral. The maximum reach distance in each direction, without losing balance, is measured and recorded. This test is a reliable and valid method for evaluating neuromuscular control and dynamic postural stability. Jump Distance. Timepoint: Before and immediately after intervention. Method of measurement: Lower limb power and functional performance were assessed using the Single-Leg Hop Test. In this test, the participant stands on one leg and performs a maximal forward jump, landing on the same leg. The test was performed separately for both the right and left legs. The distance from the toe at take-off to the heel at landing is measured and recorded. This test is widely used and validated for evaluating explosive muscular power, limb symmetry, and functional lower extremity performance.
