Can Wearable Technology be Used to Predict Exercise Intensity

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.

Inclusion Criteria: * Myocardial Infraction in the past 6 months * Able to walk on a treadmill * Aged ≥ 18 Exclusion Criteria: • Injury or condition that impedes normal gait
