Clinical Trial Summary

Aim of this study is to compare cardiopulmonary response to conical-PEP breathing during exercise in older people.


Clinical Trial Description

It is known that all most structures and physiological functions deteriorate with age, leading to decrease exercise performance, functional decline and gradual decrease of physical activity in aging.

The most essential change of respiratory physiology are: dilatation of alveoli, enlargement of air space, decrease gas exchange surface area, loss of supporting tissue for distal airway (senile emphysema), decrees of chest wall compliance and decrease of respiratory muscle strength. These changes leading to decrease lung elastic recoil, increase residual volume and functional capacity, and increase work of breathing at rest. In addition, such changes affect respiratory function, especially dynamic hyperinflation (DH) development which could be one of the factors relate to dyspnea during exercise in aging Positive expiratory pressure (PEP) therapy for DH treatment during exercise was reported in several studies.

It is possible that PEP breathing may improve cardiopulmonary response to exercise in older people. ;
