objective: effect of peppermint on exercise performance was previously investigated but equivocal findings exist. this study aimed to investigate the effects of peppermint ingestion on the physiological parameters and exercise performance after 5 min and 1 h. materials and methods: thirty healthy male university students were randomly divided into experimental (n=15) and control (n=15) groups. ...

BACKGROUND Manual hyperinflation (MH) is used to improve mucociliary clearance and alveolar expansion in mechanically ventilated patients. Despite the popularity of MH, studies with adults have shown considerable variability in the results from its use. This study assessed if professional training on the application of MH influences its performance. METHODS An experimental study was conducte...

BACKGROUND In chronic obstructive pulmonary disease (COPD), the response of the forced expiratory volume in 1 second (FEV1) after bronchodilator application is weak. Inspiratory parameters like the forced inspiratory volume in 1 second (FIV1) and inspiratory capacity (IC) can be responsive to bronchodilators. In an individual patient with COPD, a significant bronchodilator response must at leas...

abstract introduction: yoga as an exercise to improve the physical, psychological, social health condition, and promote the feeling of health in healthy people in the medical education community is considered. the aim of this research was to find the effect of 8 weeks yoga training on respiratory function and heart rate of non-athlete females. methods: 30 students of khorasgan azad university w...

BACKGROUND There are not many studies about the effects of physical activity on pulmonary function in normal population. However, it seems that strengthening and persevering respiratory muscles is an effective technique for improving pulmonary function. OBJECTIVE The purpose of this study was to evaluate and compare the effects of eight-week aerobic, resistance, and interval exercise routines...

In a group of 37 heavy snorers with obstructive sleep apnoea (OSA, Group 1) and a group of 23 heavy snorers without OSA (Group 2) cephalometric indices, ENT indices related to upper airway collapsibility, and nocturnal O2 desaturation indices were related to variables from maximal expiratory and inspiratory flow-volume (MEFV and MIFV) curves. The cephalometric indices used were the length and d...

BACKGROUND/AIMS Rehabilitation of the bilaterally paralyzed human larynx remains a complex clinical problem. Conventional treatment generally involves surgical enlargement of the compromised airway, but often with resultant dysphonia and risk of aspiration. In this retrospective study, we compared one such treatment, posterior cordotomy, with unilateral laryngeal pacing: reanimation of vocal fo...

OBJECTIVES A decrement in evoked muscle force with repetitive nerve stimulation (fade) suggests impaired neuromuscular transmission. We tested the hypothesis that fade of pulmonary function, ie, a decrease in values of FVC with the second spirometric maneuver compared to the first maneuver, occurs during impaired neuromuscular transmission. DESIGN Prospective study. PARTICIPANTS Six healthy...

<b><i>Background:</i></b> While peak in- and expiratory flow rates offer valuable information for diagnosis monitoring in respiratory disease, these indices are usually considered too variable to be routinely used quantification clinical practice. <b><i>Objectives:</i></b> The aim of the study was obtain reproducible measurements maximal inspirato...
