Objective:
This study aimed to explore the effects of Pilates combined with breathing exercise on lung function, body posture, and postural stability among female university students.
Methods:
A total of 66 females (mean age 19 years) with poor body posture were recruited from a local university and randomly divided into three groups, Pilates combined with breathing exercise group (PRT), Pilates only group (PLT), and control group (CON). Exercise interventions were conducted three times per week, 60 min per session, and lasted 16 weeks (8 weeks of group training + 8 weeks of self-training). Lung function and respiratory muscle performance, as the primary outcomes were measured using the Lung Function Tester. Secondary outcomes were standing posture and static postural stability.
Results:
Significant group differences were found at post-test in Forced Vital Capacity (FVC) (F(2, 50) = 3.63, p = 0.034, pη2 = 0.13) and Minute Ventilation (MV) (F(2, 50) = 3.52, p = 0.04, pη2 = 0.123), where the PRT group showed more improvements than the PLT group especially in FVC (mean difference = 0.43, p < 0.05). Furthermore, the PRT group showed significant improvements at post-test in Forced Expiratory Volume in 1 second as a percentage of Forced Vital Capacity (FEV1%) (F(2, 42) = 10.2, p < 0.01, pη2 = 0.327), Peak Expiratory Flow Rate (PEFR) (F(2, 42) = 5.62, p = 0.01, pη2 = 0.211) and Tidal Volume (TV) (F(2, 42) = 8.38, p < 0.001, pη2 = 0.285). Additionally, it improved body posture and static postural stability, with notable gains in certain stability measures under both eyes-open and eyes-closed conditions (p < 0.05).
Conclusions:
Combining breathing exercises with Pilates can improve lung function, body posture, and postural stability in female college students, and a longer training duration (> 16 weeks) appears beneficial for achieving optimal outcomes. These findings suggest a potential association between lung function and postural stability mediated by respiratory muscle function, which warrants further investigation.

01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
01:23Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
