What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pectoralis Minor Length and Index	PM length was measured with a caliper. The distance between the starting (origin) and ending (insertion) points of the PM muscle was measured, with the participant in supine position and the shoulder joint free.Pectoralis minor index (PMI) was obtained by dividing the PM length recorded in cm by the person's weight and multiplying the result by 100. PMI was determined by dividing the obtained value by weight	10 minutes
Scapular Dyskinesia	The lateral scapular slide test (LSST) was used to evaluate scapular dyskinesia. The distance between the inferior angle of the scapula and the closest vertebral spinous process in the standing upright position was bilaterally measured using a tape measure in three different positions	15 minutes
Scapular Muscle Endurance	Scapular muscle endurance was evaluated with the scapular isometric compression test. The participants were asked to stand upright with their arms on their sides and bring both shoulder blades closer together by maintaining this position as long as they could	10 minutes
Core Muscle Endurance	This evaluation was performed using McGill's torso muscular endurance test battery consisting of endurance tests in the trunk flexion, trunk extension (Sorensen), and right/left side bridge positions	15 minutes
