简要总结
This study aims to examine the effects of an 8-week Pilates-based exercise program on breathing functions in overweight and obese women (BMI ≥ 25). The program includes exercises for abdominal endurance and core stabilization, performed three times a week.
Participants will be divided into two groups: an exercise group and a control group. Before and after the program, measurements will include lung function (spirometry), breathing rate, breath-holding time, abdominal mobility, core endurance (curl-up test), and quality of life (SF-36 questionnaire).
The goal is to find out whether this type of exercise can improve breathing and overall health in women with excess weight.
详细描述
This study aims to investigate the effect of an 8-week Pilates-based abdominal endurance and core stabilization exercise program on respiratory function in obese and overweight women (BMI ≥ 25). The intervention program is planned to last for a total of 24 sessions, 3 days a week. The exercises will be performed using reformer and cadillac devices, under the supervision of a physical therapist, at the Easyfiz Healthy Living Center.
Participants will be randomly assigned to two groups: an experimental group receiving the exercise intervention and a control group not receiving the intervention. Assessments conducted before and after the study for both groups will include the following parameters:
- Spirometry (FEV₁, FVC, FEV₁/FVC ratio),
- Respiratory rate,
- Breath-holding time (in seconds),
- Thoracoabdominal expansion (measured with a tape measure at the epigastric, subcostal, and lower costal levels),
- Core muscle endurance (using the ACSM Curl-Up test),
- Quality of life (using the 36-item Short Form - SF-36).
The exercise program will be planned in three phases:
Weeks 1-2: beginner level, Weeks 3-5: intermediate level, Weeks 6-8: advanced level. Each session will last approximately 45-50 minutes and will consist of a warm-up (diaphragmatic breathing and mobilization), main exercise (core stability and breathing-focused movements), and cool-down (stretching and breathing relaxation exercises).

研究组 & 干预措施
Control Group
Participants in this group will not receive any specific exercise or breathing intervention. They will be instructed to maintain their usual daily activities during the study period.
Intervention Group
This group will participate in an 8-week supervised Pilates-based exercise program focused on core stabilization and abdominal endurance. Sessions will be held three times a week at Easyfiz Clinic using reformer and cadillac Pilates equipment. Each session will include diaphragmatic breathing-based warm-up and cool-down components.
干预措施: Pilates-Based Core and Breathing Exercise Program (Behavioral)
结局指标
主要结局
Forced Vital Capacity (FVC) - Spirometry
时间窗: Baseline and at 8 weeks after the intervention
Forced Vital Capacity (FVC) - Spirometry
时间窗: Baseline and immediately after the 8-week intervention
Forced vital capacity (FVC) was assessed using spirometry and expressed in liters (L). FVC represents the maximum volume of air that can be forcibly exhaled after a maximal inspiration.
Forced Expiratory Volume in 1 Second (FEV₁) - Spirometry
时间窗: Baseline and immediately after the 8-week intervention
Forced expiratory volume in one second (FEV₁) was assessed using spirometry and expressed in liters (L). FEV₁ represents the volume of air forcibly exhaled during the first second of a forced expiratory maneuver following maximal inspiration.
FEV₁/FVC Ratio - Spirometry
时间窗: Baseline and immediately after the 8-week intervention
The FEV₁/FVC ratio was calculated from spirometric measurements as the ratio of forced expiratory volume in one second (FEV₁) to forced vital capacity (FVC) and expressed as a percentage (%)
Peak Expiratory Flow Rate (PEFR) - Spirometry
时间窗: Baseline and immediately after the 8-week intervention
Peak expiratory flow rate (PEFR) was assessed using spirometry and expressed in liters per second (L/s). PEFR represents the maximum expiratory flow achieved during a forced expiratory maneuver following maximal inspiration.
Upper Thoracic Expansion (Upper Chest Mobility)
时间窗: Baseline and immediately after the 8-week intervention
Upper thoracic expansion (upper chest mobility) was assessed using a tape measure and expressed in centimeters (cm). The difference in chest circumference between maximal inspiration and maximal expiration was recorded to evaluate upper thoracic mobility.
