(at least 6 months, in order to be able to control the depth of the trance and to have a motor control allowing the realization of a spirometry) The main question: Study the significant variation of FEV1 before, during, or after the state of self-induced cognitive trance

The Effect of Curve Type Determined According to the Rigo Classification on Respiratory Muscle Strength, Quality of Life, and Functional Status in Individuals Diagnosed With Adolescent Idiopathic Scoliosis.

Adolescent Idiopathic Scoliosis (AIS) is a disorder that occurs between the ages of 10 and 18, with an unknown etiology, and is characterized by a three-dimensional deformity of the spine. It is often asymptomatic at onset but may progressively lead to cosmetic and functional impairments over time. The Rigo classification, which evaluates the structural characteristics of scoliosis, is a three-dimensional functional classification system that takes into account the direction of the curve and the involved spinal regions In studies conducted on individuals with AIS, a significant reduction in respiratory muscle strength (MIP-Maximum Inspiratory Pressure and MEP-Maximum Expiratory Pressure) has been observed, and this condition has been associated with thoracic rigidity and decreased physical activity . In individuals with AIS, a significant negative correlation has been reported between Cobb angle and FVC and FEV₁ values, as well as a moderate negative correlation between trunk rotation angle (ATR) and respiratory muscle strength (MIP and MEP). In light of these findings, it has been shown that as the severity of scoliosis increases, lung volumes decrease, and that scoliosis may affect respiration not only through a two-dimensional curvature angle but also through three-dimensional structural changes such as trunk rotation. Curves concentrated in the thoracic region according to the Rigo classification demonstrate more pronounced reductions in MIP and MEP values The impact of AIS on quality of life has been evaluated, and it has been reported that individuals with AIS score lower than healthy individuals in domains such as body image, pain, mental health, and function

AirGo™ Respiratory Monitoring in Lung Resection

Patients undergoing lung resection surgery may experience changes in respiratory function during the perioperative period. Current monitoring methods provide important clinical information but are often limited to specific time points and may not allow continuous assessment of ventilation. This study aims to evaluate the feasibility and usefulness of the AirGo™ wearable respiratory monitoring system in patients undergoing anatomical lung resection (lobectomy or segmentectomy). AirGo™ is a non-invasive, CE-marked device that continuously measures respiratory parameters, including minute ventilation and respiratory rate, through a chest-worn sensor. Participants will wear the AirGo™ device before surgery and during the postoperative period. Respiratory parameters collected by AirGo™ will be analyzed at predefined time points and compared with standard clinical monitoring methods routinely used in postoperative care, including pulse oximetry and telemetry. The primary objective is to assess changes in mean minute ventilation from the preoperative period to the first postoperative day. Secondary objectives include evaluating perioperative respiratory trends, patient comfort and compliance with the device, and the agreement between AirGo™ measurements and standard monitoring systems. The results of this study may help determine whether continuous non-invasive respiratory monitoring can improve the assessment and management of patients undergoing lung surgery.

Acute and Long-Term Effects of Integrated Myofascial Release Therapy on Respiratory Function in Healthy Adults

This study will investigate the immediate and longer-term effects of integrated myofascial release therapy on breathing-related outcomes in healthy adults. Participants will receive integrated myofascial release therapy twice a week for 6 weeks, for a total of 12 treatment sessions. Assessments will be performed before treatment, immediately after the first treatment session, at the end of the 6-week treatment period, and 1 month and 3 months after treatment. The study will evaluate pulmonary function, cough strength, and chest mobility. The aim is to determine both the immediate response to a single treatment session and whether repeated treatment produces effects that are maintained during follow-up.

Effects of Different Inspiratory:Expiratory Ratios on Respiratory and Recovery Outcomes During Dental Procedures Under General Anesthesia in Pediatric Patients

This observational study aims to evaluate the effects of different inspiratory to expiratory (I:E) ratios (1:2 vs. 1:3) during mechanical ventilation in pediatric patients undergoing dental procedures under general anesthesia. Due to behavioral challenges, dental phobia, or medical conditions, general anesthesia is often required to ensure immobility and cooperation during dental treatments in children. In the clinic where the study will be conducted, the I:E ratio is routinely adjusted approximately 20-30 minutes before the end of the procedure to facilitate a smoother transition to spontaneous breathing during emergence from anesthesia. While 1:2 is commonly used, the 1:3 ratio may improve respiratory efficiency and recovery by prolonging the expiratory phase. The study aims to compare vital signs, respiratory parameters (heart rate, blood pressure, SpO₂, EtCO₂, respiratory rate), recovery quality, and respiratory complications between the two I:E ratios. The findings aim to optimize ventilation strategies and improve patient comfort and safety during emergence from anesthesia.

Yoga-Based Breathing Exercises in a Salt-Cave Environment Versus a Standard Clinical Setting in Smokers

This randomized controlled trial evaluated whether performing the same yoga-based breathing exercise program in a salt-cave environment produced different respiratory, functional, physical activity, and quality-of-life outcomes compared with the same program performed in a standard clinical setting in adult smokers. Sixty adult smokers were randomized to either a salt-cave group or a control group. Both groups received a physiotherapist-supervised yoga-based breathing exercise program for 6 weeks, twice weekly, in 50-minute sessions. The intervention content, frequency, duration, and physiotherapist supervision were identical in both groups; the only planned between-group difference was the intervention setting. Spirometric outcomes were assessed at baseline, week 3, and week 6. Functional exercise capacity, physical activity, and quality of life were assessed at baseline and week 6.

Gulf Long-Term Follow-Up Study

Background: * There has been little research on the long-term health effects from oil spills, even though at least 10 percent of all oil tanker spills between 1970 and 2009 have affected coastal populations. The Deepwater Horizon disaster, with its release of approximately 5 million barrels (\~680,000 tons) of crude oil into the Gulf of Mexico, is far larger than any of the individual tanker spills. Given the magnitude of this spill and the scope of the potential exposures, including the 55,000 workers involved in clean-up efforts and countless residents of the affected areas, researchers are interested in monitoring Gulf clean-up workers to understand the adverse consequences of oil spills in general. * The Gulf Long-term Follow-up Study will investigate health effects associated with the clean-up activities following the Deepwater Horizon disaster in the Gulf of Mexico on April 20, 2010. More than 100,000 persons completed safety training in preparation for participation in clean-up activities related to the spill. Many of these individuals participated in active clean-up efforts, but others did not. Exposures among persons involved in clean-up range from negligible to potentially significant, especially for workers involved in tasks associated with direct exposure to crude or burning oil, or to chemical dispersants. However, prediction of adverse health effects is not possible because the long-term human health consequences of oil spills are largely unknown. In addition to the oil itself, the widespread economic and lifestyle disruption caused by the oil spill may contribute to mental health problems among this population. Objectives: \- To investigate potential short- and long-term health effects associated with clean-up activities and exposures surrounding the Deepwater Horizon oil spill. Eligibility: \- English-, Spanish-, and Vietnamese-speaking workers and volunteers at least 21 years of age engaged or potentially engaged in oil spill clean-up operations in the Gulf of Mexico, or who lived in affected areas (Louisiana, Mississippi, Alabama, and Florida coastal regions). Design: * Participants will be divided into groups of those who performed oil-spill clean-up-related work ( exposed ) and those who did not engage in clean-up-related work ( unexposed controls). * Participants will be screened with a full medical history and physical examination, as well as an interview to determine the nature of their potential exposure. * Participants will provide blood, hair, toenail, urine, and saliva (spit) samples. Participants may also have a lung function exam. * Participants will have researchers collect dust from their homes by using wipes and special vacuum bags. * Participants will also provide detailed contact information, including their Social Security number, to be contacted in the future for long-term health follow-up appointments. These appointments will include 30-minute telephone interviews every 2 years.

Combined SOVT and Respiratory Exercises: Effects on MPT and Respiratory Function

This study aims to investigate the effects of combined SOVT and breathing exercises, administered twice weekly for six weeks to conservatory students, through a randomized controlled trial. The study has two hypotheses: H1: Combined SOVT and breathing exercises increase the maximum phonation duration. H2: Combined SOVT and breathing exercises improve spirometric parameters (FEV₁, FVC, FEV₁/FVC, and PEF).

Effects of Diaphragmatic Breathing During Equipment-Based Pilates in Women

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.

Effects of Core and Inspiratory Muscle Training on Muscle Oxygenation and Athletic Performance İn Young Soccer Players

The purpose of this randomized controlled trial is to investigate the effects of core training and inspiratory muscle training (IMT) on muscle oxygenation and athletic performance in youth male soccer players aged 15-18. A total of 54 healthy soccer players will be included and randomly assigned into three equal groups: the Control Group, the Core Training Group, and the Core Training + IMT Group. All interventions will be implemented for 8 weeks in addition to routine soccer training sessions. Assessments will be performed at baseline (Week 0), mid-intervention (Week 4), and post-intervention (Week 8). The primary outcome measures of the study are aerobic capacity assessed by the Yo-Yo Intermittent Recovery Test Level 1 and muscle oxygenation parameters monitored via near-infrared spectroscopy (NIRS) using a MOXY monitor. Secondary outcome measures include sprint performance, agility, dynamic balance, core muscle strength and endurance, inspiratory muscle strength, lower extremity explosive power, and soccer-specific technical performance tests. Overall, this study aims to reveal the combined effects of core training and inspiratory muscle training on muscle oxygenation, respiratory functions, aerobic capacity, and soccer performance, while explaining the underlying physiological mechanisms in youth athletes.

Respiratory Function and Athletic Performance in Professional Soccer Players

This prospective observational study aims to investigate the relationship between respiratory function and multidimensional athletic performance parameters in professional soccer players. The primary hypothesis of the study is that soccer players with enhanced respiratory function and superior respiratory muscle strength will exhibit optimized motor performance outcomes and shorter (faster) reactive reaction times. Investigators will evaluate respiratory muscle strength, spirometric pulmonary functions, dynamic balance, core and abdominal endurance, and reactive visuomotor reaction times during a single testing session within the competitive season.

Inspiratory Muscle Training in Children With Cerebral Palsy: Effects on Respiratory and Motor Functions

The results of the study aim to provide a clinical perspective for clinicians working with patients diagnosed with cerebral palsy between the ages of 5-18 years and to contribute to the literature.

Effect of Digital Incentive Spirometry Training in Healthy Adults

This prospective single-group pre-post study evaluated whether digital incentive spirometry training using the TryBreath system could improve pulmonary function, respiratory muscle strength, exercise capacity, and symptom scores in healthy adults. Participants completed a 3-week training period with app-recorded adherence and were assessed before and after the intervention.

Functional and Respiratory Determinants of Long-Term Colorectal Cancer Outcomes

Colorectal cancer is one of the most commonly diagnosed malignancies worldwide and a leading cause of cancer-related morbidity and mortality. Its global incidence continues to increase, with a substantial proportion of cases diagnosed at advanced stages, which adversely affects prognosis. Patients diagnosed at an early stage and treated with surgery have significantly better long-term survival outcomes. Five-year survival rates are approximately 90% for stage I disease, decreasing to around 70% in stage II and 60% in stage III, and dropping to as low as 8% in stage IV disease. Advanced age, family history, and environmental exposures are well-established risk factors for colorectal cancer. In addition, modifiable lifestyle factors-including smoking, physical inactivity, unhealthy dietary patterns, and obesity-have been shown to significantly increase the risk of disease. Although surgical resection remains the cornerstone of curative treatment in colorectal cancer, long-term outcomes are influenced not only by tumor stage but also by various patient-related factors, including comorbidities, functional capacity, and respiratory reserve. Functional status, which reflects a patient's ability to perform activities of daily living, is a key determinant of postoperative recovery and long-term outcomes. Reduced functional capacity has been associated with poorer long-term survival, diminished quality of life, and increased late morbidity. Therefore, objective preoperative assessment of functional status is considered essential for predicting long-term prognosis. Respiratory function also plays a critical role, particularly in patients undergoing abdominal surgery. Impaired pulmonary capacity increases the risk of postoperative pulmonary complications, prolongs hospital stay, and may indirectly affect long-term survival. However, studies evaluating the impact of preoperative respiratory parameters on long-term outcomes in patients with colorectal cancer remain limited. Furthermore, comprehensive analyses integrating both functional capacity and respiratory function are scarce in the current literature. Therefore, further investigation in this area is warranted. The aim of this study is to evaluate the impact of functional status and respiratory parameters on long-term clinical outcomes in patients with colorectal cancer. H0: There is no statistically significant association between functional status, respiratory parameters, and long-term clinical outcomes in patients with colorectal cancer. H1: There is a statistically significant association between functional status, respiratory parameters, and long-term clinical outcomes in patients with colorectal cancer.

The Effects of a Mindfulness Program on Running Performance, Respiratory Function, and Heart Rate Variability

Broadly, the objective of the research is to evaluate the effectiveness of a specific breathwork program (Les Mills Breath) on various physiological variables related to running performance, compared to a mindfulness control (20 minutes of guided meditation). There are three specific research questions: 1) Does daily participation in a 20-minute breathwork program improve respiratory function more than a mindfulness control intervention? 2) Does daily participation in a 20-minute breathwork program improve heart rate variability (an indicator of parasympathetic nervous system activity which is associated with enhanced exercise recovery) more than a mindfulness control intervention? 3) Does daily participation in a 20-minute breathwork program increase self-selected running speeds at relative moderate and vigorous intensities more than a mindfulness control intervention? The intended outcomes of the current research are to contribute to the field of research which has examined various forms of "respiratory training" and their effects on athletic performance, specifically running. While certain training protocols have been shown to be effective, there are issues of accessibility which persist. Methods of respiratory training/breathwork which are more easily available to recreational athletes are understudied with regards to running performance, hence the current research.
