To determine if maximum heart rate and subsequent recovery time to baseline correlates with participant fitness by undertaking a Steady-state Cycle Test in the healthy adult population. Fitness will be determined by a combination of the International Physical Activity Questionnaire and participant’s maximal oxygen uptake (VO2 max) during the Astrand-Rhyming Cycle Ergometer Test. If indicative, the Steady-state Cycle Test will then be trialled in the burn injury patient population. The Steady-state Cycle Test is proposed due to:
- The submaximal nature of the test
- Ease of test administration
iii. Ease of result measurement
- Reduction of heart rate confounders in a metabolic injury
- Removal of the subjective nature of self-reported fitness evaluation
If the sole measure of heart rate is a successful indicator of fitness, this would be a simple and appropriate test to administer to patients on admission to the Burns Unit, allowing guidance on management and projected recovery.
Design: Observational study
Setting: State Burns Unit of Western Australia, Fiona Stanley Hospital
Subjects: Healthy adults aged between 18 and 65 years.
Intervention: 6 minute cycle test at 75 watts at 50 rpm.
- Maximum heart rate at the six minute mark of the Steady-state Cycle Test.
- Recovery time to baseline post completion of the Test.
– Self-reported as per the IPAQ.
– Maximal oxygen uptake (VO2 max) determined by the Astrand-Rhyming Ergometer Cycle test.
Hypothesized outcome: that participants who achieve a lower heart rate and faster time to recovery will have higher scores on the IPAQ and maximal oxygen uptake, indicating higher baseline fitness, regardless of age and gender.
