Research summary
There is only one study (Woolf-May & Ferrett, 2008)that has evaluated the oxygen cost of each of the incremental stages of the Incremental Shuttle Walk Test(Singh et al, 1992)in cardiac patients. There remain a number of questions and limitations to these results in order to provide widen practicability to patients attending cardiac rehabilitation, including females, PCI and CABG. There are both participant and protocol limitations to the applicability of this to cardiac rehabilitation.
To establish accurate and true oxygen uptake values a breath by breath portable gas analyser will be used. The patient is fitted with a face mask which is attached by a tube which directs the air to the portable gas analyser. During the exercise test the participants will be closely monitored using a Polar heart rate monitor (Appendix 9) and the Borg rating of perceived exertion scale (Appendix 10).
The Incremental Shuttle Walk Test (Singh et al, 1992) is currently recommended to establish functional capacity in this clinical population. The test will last for a maximum of 12 minutes with the walking speed gradually increasing each minute. Each participant will begin by having a practice run wearing a face mask to gain familiarisation with the test.
