The usefulness of inspiratory muscle training (IMT) in chronic airflow limitation (CAL) patients is a controversial issue, mainly due to differences in the training load. To further evaluate this aspect, we studied the effect of the magnitude of the load using a threshold pressure trainer. Ten CAL patients (5 males, 5 females) 67 +/- 2 yrs (mean +/- SEM) and forced expiratory volume in one seco...

In 1976 LEITH and BRADLEY [1] generated the hypothesis that the inspiratory muscles, like other muscles, could be trained. In the now classic study 12 healthy adults were divided into three groups of four. One group underwent strength testing, consisting of maximal voluntary efforts against a closed airway over a range of lung volumes for 30 min per day for 5 days a week for 5 weeks. The second...

This research examined the effects of respiratory-muscle (RM) training on RM function and exercise performance in older women. Twenty-six women (60-69 yr of age) were assessed for spirometry, RM strength (maximal inspiratory and expiratory pressure), inspiratory-muscle endurance, and walking performance to a perceived exertion rating of "hard." They were randomly allocated to a threshold RM tra...

QUESTIONS Does inspiratory muscle training improve maximal inspiratory pressure in intubated older people? Does it improve breathing pattern and time to wean from mechanical ventilation? DESIGN Randomised trial with concealed allocation and intention-to-treat analysis. PARTICIPANTS 41 elderly, intubated adults who had been mechanically ventilated for at least 48 hr in an intensive care unit...

This study documented the effect of inspiratory muscle conditioning in children with cystic fibrosis. Subjects, ages 7 to 14 years, were divided into two groups. The experimental group (n = 10) trained at a high pressure load (> or = 29 cm H2O) and the control group (n = 10) trained at a minimal pressure load (< or = 15 cm H2O), using a threshold loading device. Subjects trained 30 min a day fo...

BACKGROUND Physical exercise reduces glucose levels and glucose variability in patients with type 2 diabetes. Acute inspiratory muscle exercise has been shown to reduce these parameters in a small group of patients with type 2 diabetes, but these results have yet to be confirmed in a well-designed study. The aim of this study is to investigate the effect of acute inspiratory muscle exercise on ...

Inspiratory muscle dysfunction has been shown to be related to hypercapnia and hence, to ventilatory insufficiency in patients with chronic obstructive pulmonary disease (COPD) [1]. Accordingly, treatment of inspiratory muscle dysfunction has gained interest in the last decade. Among other treatment modalities, such as pharmacotherapy and respiratory muscle rest, training of the inspiratory mus...

There is very little information about the effect of inspiratory muscle training on inspiratory flow (V'I) and thus on power output (PO) in patients with chronic obstructive pulmonary disease (COPD). In this study we aimed to evaluate the changes induced by training on the determinants of PO. Thirty one patients with severe COPD were randomly divided into: Group 1, trained with 30% maximal insp...

This case study describes the support given to a British elite athlete in the build up to the 2004 Athens Olympic Games. The athlete had complained of breathing symptoms during high intensity training that led to a reduction in performance and premature cessation of training. Following a negative eucapnic voluntary hyperpnoea challenge and observation during high intensity exercise, the athlete...
