Brief Summary

There is a knowledge gap in the literature around using watts to measure exercise intensity in walking and running, this is largely due to new technological developments. Whereas the relationship is widely recognised and used for cycling in elite to clinical populations. While the relationship breathing rate and exercise intensity is well established, this are no guidelines using breathing rate as a physiological measure of intensity. New technology may aid to bridge these gaps. The main aims of the study are: - Can the relationship between oxygen uptake and watts during incremental exercise Can breathing frequency be used to determine aerobic exercise intensity The participants will complete two 9 minute incremental accredited exercise tests on the flat around cones and on treadmill at the given speed of walking around the cones. The test will stop at 6.8kph or at participant volition.

Outcome Measures

Primary Outcomes (1)

  • Can a Stryd accelerometer be used to predict V̇o2max and therefore be used to gather a baseline for exercise prescription in cardiac populations post myocardial infraction.

    Develop a regression equation for the use of watts derived from a foot pod to predict vo2. Assessing watts per kg of body mass against vo2 per kg of body mass, offering insight as to how this population group can use watts to prescribe exercise.

    1 day of testing, enrolment may be within 1 month prior to the test

Secondary Outcomes (1)

  • Can a breathing frequency monitor be used to predict aerobic exercise intensity in cardiac populations post myocardial infraction.

    1 day of testing, enrolment may be within 1 month prior to the test

Study Arms (1)

Myocardial Infraction

Participants who have suffered a myocardial infraction in the past 6 months and are actively enrolled onto a cardiac rehabilitation programme

Other: Incremental Shuttle Walk Tests

Interventions

The participants will walk on the flat around cones placed 9 meters apart inline with the procedure for the incremental shuttle walk test. They will also walk at a matched speed to the incremental shuttle walk test on a treadmill. This will be performed in a counter balanced procedure to reduce any benefit of a learning effect.

Also known as: ISWT
