Effects of Diaphragmatic Breathing During Equipment-Based Pilates in Women

16 juni 2026 bijgewerkt door: Nava Mokhtari, Istanbul Aydın University

The Effects of Diaphragmatic Breathing Exercises on Core Stabilization Muscle Strength, Peak Expiratory Flow, and Chest Expansion in Women Performing Equipment-Based Pilates: A Randomized Controlled Trial

This randomized controlled study aims to investigate the effects of diaphragmatic breathing exercises on core stabilization muscle strength, peak expiratory flow (PEF), and chest expansion in women performing equipment-based Pilates.

A total of 44 healthy women aged 20 to 50 years who regularly participate in equipment-based Pilates exercises will be recruited and randomly assigned to one of two groups. The intervention group will receive equipment-based Pilates training combined with diaphragmatic breathing exercises, while the control group will receive equipment-based Pilates training only.

Both groups will participate in supervised exercise sessions twice weekly for 8 weeks. Core stabilization muscle strength, peak expiratory flow, and chest expansion measurements will be assessed before and after the intervention period.

The findings of this study may contribute to a better understanding of the additional effects of diaphragmatic breathing exercises on respiratory function and core stabilization in women performing Pilates.

Gedetailleerde beschrijving

Pilates is a popular exercise approach that is widely used in both healthy individuals and various clinical populations to improve flexibility, muscular strength, postural control, and core stability. One of the fundamental principles of Pilates is coordinated breathing during movement. Appropriate breathing patterns may enhance trunk stabilization and optimize exercise performance.

The diaphragm is the primary muscle of respiration and also plays an important role in core stabilization through its interaction with the abdominal muscles, pelvic floor muscles, and deep spinal stabilizers. Diaphragmatic breathing exercises have been shown to improve respiratory function, chest mobility, and trunk muscle activation. However, limited evidence exists regarding the additional effects of diaphragmatic breathing exercises in women who regularly perform equipment-based Pilates exercises.

The aim of this randomized controlled study is to investigate the effects of diaphragmatic breathing exercises on core stabilization muscle strength, peak expiratory flow (PEF), and chest expansion in women performing equipment-based Pilates.

Healthy women aged 20 to 50 years who regularly participate in equipment-based Pilates exercises will be recruited. Participants who meet the eligibility criteria and provide written informed consent will be randomly assigned to one of two groups. The intervention group will receive equipment-based Pilates exercises combined with diaphragmatic breathing exercises, whereas the control group will receive equipment-based Pilates exercises only.

Both groups will participate in supervised exercise sessions twice weekly for a total of 8 weeks. Outcome assessments will be performed before and after the intervention period. Core stabilization muscle strength will be evaluated using a pressure biofeedback unit. Peak expiratory flow will be assessed using a peak flow meter, and chest expansion will be measured at different thoracic levels using a tape measure.

The primary outcome of the study is core stabilization muscle strength. Secondary outcomes include peak expiratory flow and chest expansion measurements. The findings of this study are expected to contribute to the understanding of the role of diaphragmatic breathing exercises in improving respiratory function and core stabilization in women performing equipment-based Pilates and may provide evidence for the development of more effective exercise programs.

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Pilates + Diaphragmatic Breathing
Participants received equipment-based Pilates training combined with diaphragmatic breathing exercises twice weekly for 8 weeks. Each session lasted approximately 50 minutes and was supervised by the same physiotherapist.
Gedragsmatig: Diaphragmatic Breathing Exercise
Participants performed diaphragmatic breathing exercises twice weekly for 8 weeks under the supervision of a physiotherapist. The breathing exercises focused on diaphragmatic activation and controlled breathing patterns and were integrated into the Pilates training sessions.
Gedragsmatig: Equipment-Based Pilates Training
Participants received equipment-based Pilates training twice weekly for 8 weeks. Each session lasted approximately 50 minutes and was supervised by the same physiotherapist. The program focused on core stabilization, posture, flexibility, and muscle strengthening.
Actieve vergelijker: Pilates Only
Participants received equipment-based Pilates training twice weekly for 8 weeks.
