IMPROVEMENTS IN ASTHMATICS

& THOSE WITH RESPIRATORY DISORDERS

Strengthens the inspiratory muscles

         As you inhale against the load, the inspiratory muscles are made to work harder; this training stimulus induces improvements in the force-generating capacity and metabolic efficiency of the inspiratory muscles (Sharpe et al., unpublished observations)

  Breathing improved in 3 weeks

         Training is accomplished with as little as 5 minutes training per day, and benefits are perceived by patients within 3 weeks of starting the training (McConnell et al., 1998)

  Relieves the symptoms of Asthma

         In randomised, controlled trials, on mild / moderate asthmatics, POWERbreathe increased inspiratory muscle strength by a mean of 11% in just 3 weeks (McConnell et al., 1998)

         Inspiratory muscle training has been shown to relieve the symptoms of asthma by improving lung function, resulting in reduction of medication and a fall in hospitalisations (Weiner et al., 1992)

  Relieves the symptoms of Dyspnoea and other respiratory disorders

         Dyspnoea is a common feature of many disorders. Its source may be respiratory, cardiovascular, neuromuscular or even psychological. Inspiratory muscle weakness has been identified as a contributory factor in the perception of dyspnoea (Killian, 1998)

         Training of the inspiratory muscles has been demonstrated to increase their strength, resistance to fatigue and, most importantly, to reduce exertional dyspnoea. (Lisboa, 1994; Copestake & McConnell, 1995; Lisboa, 1997; McConnell et al., 1998)

         Reduction in exertional dyspsnoea has been demonstrated in healthy elderly people (Copestake& McConnell, 1995), asthmatics (McConnell et al., 1998) and patients with COPD (Lisboa et al., 1994, 1997)

  Proven to enhance endurance in patients with COPD (Chronic Obstructive Lung Disease)

         In randomised, controlled trials, POWERbreathe has been shown to generate improvements in inspiratory muscle strength of 55% and endurance of 86% in patients with COPD (Newall et al., 1998)

  Inspiratory muscle training has improved inspiratory muscle function in the following conditions:

         Spinal cord injury (Huldtgren et al., 1980, Gross et al., 1980)

         Cystic fibrosis (Sawyer et al., 1993)

         Chronic heart failure (Cahalin et al., 1997, Mancini et al., 1995)

         Neuromuscular diseases including MS (Foglio et al., 1994), Duchenne muscular dystrophy (Wanke et al., 1994)

         Heart-lung transplant patients (Ambrosino et al., 1996)

Maintenance of lung function during Corticosteroid use

         Corticosteroids are used to treat a large number of disease conditions, but significant reductions in inspiratory muscle strength have been documented after an acute bout of oral corticosteroid treatment. Research has shown that a concomitant period of inspiratory muscle training can eliminate the fall in inspiratory  muscle strength, therefore maintaining lung function during corticosteroid use (Weiner et al., 1995)
