Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Sportive swimming is described as the athlete's ability to complete specific distances in water in the quickest amount of time using freestyle, backstroke, breaststroke, or butterfly strokes. The backstroke technique is performed in supine posture, while the other techniques are swum in facedown, horizontal, and near-horizontal positions. Variable approaches have varied characteristics in terms of body position, leg kick, arm pulling, head position, respiration, and condition.
Biomechanically, our myofascial connections also helps swimmers while they swim. Tightening Superficial Front Line (SFL) causes flexion of the hips and trunk in motion also produces hyperextension at the top of the neck. The large muscles of the pectoralis and latissimus provide the motive force for the large movements of adduction and extension, such as a swimming stroke. Vertical fibers in the fascia on the profound side of the epimysium of the pectoralis major, which does indeed connect from the rectus attachment to the lower part of the fascia colli superficialis (and sternocleidomastoid (SCM)). Lower extremity also coordinates stability while upper part of the body initiates movements between phases İliopsoas starts the hip flexion and is followed up by the rectus femoris initiates knee extension to continue horizontal movement in the water.
Because of the demands of the sport, swimmers have a more rounded forward posture. When the head is forward, the cervical spine is hyperextended, the thoracic spine is in slight flexion, and the lumbar spine is in slight extension, this is known as forward posture. Muscle imbalances in the shoulders are to blame for this forward posture. In the recovery phase of swimming, the scapula must retract and protract along the thoracic wall. The subacromial space reduces with protraction because of the swimmer's adaptation due to sport. Stretching the scapular protractors such as the pectoralis major muscle has been shown to have a considerable impact on the degree of forwarding shoulder posture (FSP) in healthy people. Besides this adaptation also, swimmers with shoulder pain because of more active trigger points can lead to the development of mechanical hypersensitivity compared to ones that do not have any shoulder pain.
As summarized above, swimming athletes generally have a forward posture due to their adaptation to water. In our opinion, this posture may be due to the tension of the anterior group myofascial structures, and releasing the fascia by stretching might affect swimmers' performance. Master swimmers have that adaptation far more compared to young swimmers. Therefore, we can better observe the effects of Sternocleidomastoid, Pectoralis major, and İliopsoas muscle stretching on swimming performance by testing swimmers at distances such as 800 meters.
H0: There is no significant difference between the 800-meter performance measurements of the people in the group that added stretching of specific muscles to their normal training and those in the group that did not add stretching.
H1: There is a significant difference in the 800-meter performance measurements of the group with specific muscle stretching added to their normal training and the people in the group without stretching.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
The Study Group
800-meter swimming performance tests were administered to all swimmers prior to the measurement. The study group started to do stretch exercises every day for 6 weeks. At the end of six weeks, performance tests and myoton measurements were administered and analyzed for both groups.
Stretching
Master swimmers will be taught iliopsoas, sternocleidomastoid and pectoralis major stretching exercises as stretching exercises. Participants will stretch daily for 3 repetitions, each stretching for 20 seconds.
Participants will continue their swimming training 2 days a week.
Training
Participants continued their swimming training 2 days a week.
The Control Group
800-meter swimming performance tests were administered to all swimmers prior to the measurement. The control group just continued their regular training for 6 weeks. At the end of six weeks, performance tests and myoton measurements were administered and analyzed for both groups.
Training
Participants continued their swimming training 2 days a week.
