This study aimed to establish normative values for maximum inspiratory pressure and maximal expiratory pressure in the Turkish population while creating specific equations to calculate these values. The study involved 219 healthy adults, with a minimum of 50 individuals in specific age ranges: 20-29, 30-39, 40-49, and 50-60 years. Each age group comprised at least 25 males and 25 females. Participants were required to be free from health conditions influencing respiratory muscle strength and non-smokers. Measurements of maximum inspiratory pressure and maximal expiratory pressure were recorded for all participants. As a result of the regression analysis performed for the maximum inspiratory pressure values, the model P value was < .001, and the R2 value was found to be 0.261. The equation obtained as a result of the model was: 82.583 - 3.218 × gender - 0.093 × age+9.534 × height+0.343 × weight. As a result of the regression analysis performed for maximal expiratory pressure values, the model P value was <.001, and the R2 value was found to be 0.285. The equation obtained as a result of the model was: 157.165 - 35.522 × gender - 0.271 × age-42.036 × height+0.787 × weight. The newly developed equations offer valuable tools for evaluating respiratory muscle strength in the Turkish population. These results confirm the importance of using maximum inspiratory pressure and maximal expiratory pressure to monitor changes in each patient, while also emphasizing the necessity of reliable reference equations.

Introduction/aims: We aimed to determine differences in diaphragm thickness by including/excluding pleural and peritoneal membranes, the variability in diaphragm thickness over the apposition zone, and the predictors of diaphragm thickness and excursion measurements.
Methods: At least 10 male and female subjects were recruited for each decade of life. Spirometry, respiratory muscle strength, and the diaphragm ultrasound (US) measurements were performed.

Lymphedema is a chronic, progressive condition that has major physical and psychological consequences. It was aimed to examine the respiratory functions, respiratory muscle strength, physical activity level, and functionality of patients with lower extremity lymphedema and to compare them with healthy controls. A total of 82 individuals (29.

Background: The fatigue of the inspiratory musculature, particularly the diaphragm, has been demonstrated to exert systemic effects on the body, impacting cardiovascular and performance outcomes. This study aimed to evaluate the influence of an inspiratory muscle fatigue protocol on respiratory muscle strength, functionality, and muscle oxygen saturation in older adults.
Methods: A single-blinded randomized controlled clinical trial was conducted on twenty-four older adults aged over 60 years, who met inclusion criteria were physically independent in terms of gait and functionality.

Objective: This study aimed to investigate the effects of combining inspiratory muscle resistance with strength training on lung function and aerobic capacity in artistic swimmers.
Methods: This research constitutes a placebo-controlled randomized trial, involving a five-week walking program conducted twice a week. Fourteen female artistic swimmers were randomly assigned to either the experimental group (TG group, = 7) or the control group (CG group, = 7).

Rationale: Anti-mitochondrial antibodies (AMA) M2-positive myositis can lead to severe respiratory failure. Traditional immunotherapies sometimes fail to address respiratory failure. Herein, this CARE-compliant case report described a patient with AMA-M2-positive myositis who recovered from ventilation with tracheostomy owing to immunotherapy-resistant respiratory failure to spontaneous breathing after modified lung volume recruitment (mLVR) therapy.
