Parity and Respiratory Muscle Strength in Women

Investigating the Relationship Between Parity and Respiratory Muscle Strength in Women.

The aim of this study is to investigate the relationship between parity and respiratory muscle strength in women.

Study Overview

• Status: Recruiting
• Conditions: Woman; Core Stability; Respiratory Muscle Strength; Parity

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Respiratory Muscle Strength/ maximal inspiratory pressure (MIP)	Participants' maximal inspiratory pressure (MIP) measurements will be evaluated using the COSMED Pony FX spirometry device according to American Thoracic Society/European Respiratory Society standards.	On the day of enrollment
Respiratory Muscle Strength/maximal expiratory pressure (MEP)	Participants' maximal expiratory pressure (MEP) measurements will be evaluated using the COSMED Pony FX spirometry device according to American Thoracic Society/European Respiratory Society standards.	On the day of enrollment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pressure Biofeedback Unite	Core muscle stabilization will be measured with The Stabilizer Pressure Biofeedback Unit. Individuals are asked to lie down in the supine and prone positions. After the pressure cell of the instrument is placed with reference to the Anterior superior iliac spines (ASIS) and Posterior superior iliac spines (PSIS), the subjects are asked to perform a drawing-in maneuver. The contraction that can be sustained for 10 seconds is recorded in mmHg.	On the day of enrollment
Trunk Muscle Endurance Tests	The endurance of the trunk flexor, trunk extensor and lateral flexor muscles is evaluated by recording the maximum time that the person can maintain the test position.	On the day of enrollment
Physical Activity Level	Individuals' physical activity levels will be questioned with the International Physical Activity Questionnaire (IPAQ) Short Form. It is a 7-item scale. Physical activity levels are classified into 3 categories according to the scores obtained by multiplying the duration, frequency and MET values of the physical activities that the participants participated in within 7 days and for at least 10 minutes. Accordingly, <600 MET - min/week is defined as inactive, 600 - 3000 MET - min/week low, and >3000 MET - min/week is defined as sufficient physical activity level.	On the day of enrollment
