We studied the effect of order in the performance of maximal respiratory pressures (PImax and PEmax). For this purpose 20 healthy subjects (male/female: 1/1) were studied. PImax and PEmax were obtained on 2 different days at the same hours (9 and 12 a.m.). The test order was random. On the first day, the entire manoeuvre was performed twice, changing the order in the second determination. On the second day, we repeated the same exercises with reversed order. There were no differences between values for PImax and PEmax when we altered the order of manoeuvres on various days.

In this quasi-experimental before-after trial, we investigated the effects of a high-intensity, low-repetition inspiratory muscle training (HI-LRMT) protocol on respiratory muscle strength in instrumental musicians. In addition, was to estimate the prevalence of "non-responders" (NRs) in terms of muscle force after intervention. Healthy musicians ( = 48) were divided into 2 groups: HI-LRMT ( = 33) and a control group that did not train (CG, = 15).

Background: Spinal cord injury (SCI) detrimentally impacts individuals' exercise capacity and respiratory parameters depending on sensory, motor, and autonomic dysfunctions. Regular physical activity (PA) positively impacts cardiovascular health and pulmonary function in these individuals. This study determined the relationship between PA and exercise capacity and respiratory parameters in individuals with SCI.

BACKGROUND The effects of cigarette smoking on the health of active smokers and passive smokers have long been known, in contrast to the effects of alternative forms of nicotine intake that are gaining popularity. The aim of the study was to assess the effects of smoking traditional cigarettes and alternative forms of nicotine intake on the functional state of the respiratory system of smokers and non-smokers. MATERIAL AND METHODS Study participants (n=60) were divided into 3 groups: non-smokers (control group), cigarette smokers, and nicotine alternative users.

Background: Swallowing is a complex process that requires the coordination of muscles in the mouth, pharynx, larynx, and esophagus. Dysphagia occurs when a person has difficulty swallowing. In the case of subjects with respiratory diseases, the presence of oropharyngeal dysphagia potentially increases lung disease exacerbations, which can lead to a rapid decline in lung function.

Purpose: The main aim of the trial was to assess the effectiveness of inspiratory muscle training on respiratory muscle strength, functional capacity, fatigue, and stress in post-surgical breast cancer survivors.

Methods: Forty-seven females who had undergone unilateral post-mastectomy were randomly assigned to an intervention group (IG; n = 24) and a control group (CG; n = 23). Both groups received aerobic exercise training.
