Abstract
Introduction
Respiratory muscle training has been found to increase both the strength and endurance of respiratory muscles. However, the evidence regarding whether the adaptation of respiratory muscles is transferred to improvements in oxygen consumption is less conclusive. In particular, there is a lack of research into the effects of respiratory muscle training on the metabolism of untrained subjects at submaximal levels of exercise intensity, which are more representative of the activities of daily living.
Exercise prescription forms an essential part of osteopathic treatment but the respiratory muscles are often neglected in treatment. Dyspnoea and low exercise tolerance are common symptoms of many chronic diseases, such as chronic obstructive pulmonary disease, asthma and rheumatoid arthritis. Respiratory muscle training may provide a valuable adjunctive treatment.
Methodology
A screening questionnaire was randomly distributed to students attending the British College of Osteopathic Medicine. Twenty students satisfying the inclusion criteria were selected as subjects and divided into two matched control groups on the basis of their maximal oxygen uptake. The test group (n=10) trained for six weeks using the Ultrabreathe(tm) respiratory trainer. The control group (n=10) did not train during the six week training period. All subjects undertook a ten minute, fixed-workload, submaximal bicycle ergometer test at the beginning and end of the training period, with measurement of respiratory gases using the Cortex MetaLyzer 3B(r). The subjects undertook no other training throughout the six week period.
Results
T-tests demonstrated that there was no significant change in oxygen uptake, ventilatory equivalent for oxygen or minute volume following six weeks of respiratory muscle training (P>0.05). There was a significant decrease in the rating of perceived exertion in the test group following training (P<0.05).
Conclusion
The null hypothesis that six weeks of respiratory muscle training does not affect oxygen consumption in asymptomatic, sedentary subjects at a fixed level of submaximal work was accepted.
The most convincing explanations for the lack of significant findings in respect of the effects of respiratory muscle training on exercise performance in this study are the poor reliability of the submaximal test employed and the short duration of training.
