Parity and Respiratory Muscle Strength in Women

In normal anatomical structure, there is myofascial continuity between the diaphragm, abdominal muscles and pelvic floor muscles. In addition to this anatomical unity, when the diaphragm muscle descends with inhalation, the pelvic floor muscle moves caudally, allowing breathing to encounter less resistance; the opposite occurs during exhalation.

Pregnancy and childbirth create anatomical and physiological changes in the female body. As a result of the growing uterus, the diaphragm moves upwards, while the pelvic floor muscles become depressed as intra-abdominal weight increases. On the other hand, it is thought that increased ligament laxity is responsible for changes in the body's muscle structure, especially in the lower body. Considering these pregnancy-related changes, the functions of these interrelated muscle groups may be affected and synergistic movements in the woman's body may be disrupted after pregnancy.

The aim of this study is to examine whether the anatomical structures affected during pregnancy have permanent effects on respiratory muscle strength and core muscles after birth. Volunteers who agree to participate in the study will be divided into groups according to their birth counts and respiratory and core muscles will be evaluated using objective methods.
