Summary

Pectoralis minor (PM) are muscle groups that play a role in stabilizing the scapula. The aim of this study is to evaluate the effects of PM muscle length on scapular and core muscle endurance in the dominant and non-dominant limb. A total of 93 women were included in the study. Demographic data were recorded. PM length was measured with a caliper. Scapular muscle endurance was evaluated using the scapular isometric compression test and core endurance using McGill’s torso-muscular endurance test battery. Multiple linear regression analysis revealed that dominant pectoralis minor length and pectoralis minor index and non-dominant pectoralis minor length and pectoralis minor index can affect trunk flexion and trunk extension. The longest muscle endurance time was found in the scapular test (46.32), followed by the core tests performed in extension (30.37 s), flexion (26.17 s), dominant side bridge position (10.06 s), non-dominant side bridge position (9.36 s). PM length had no effect on scapular and core muscle endurance measured in the side bridge position. In the trunk flexion and extension positions was directly related to the dominant and non-dominant PM muscle length. KEY WORDS: Pectoralis minor length; Scapular muscle endurance; Core muscle endurance; Dominant arm
