Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive 12 weeks of supervised High Intensity Interval Training (HIIT), followed by 12 weeks of home-based HIIT (in an unsupervised environment). The HIIT protocol will consist of: warm-up for 5 min and at 60% of maximal heart rate (HRmax) followed by 4 x 4 min intervals at 85-95% HRmax interspersed with 3 min ‘recovery’ periods at 60% HRmax, then a 5 min cool down. All training will be conducted on three days per week. Weeks 1-12 will be supervised by an Accredited Exercise Physiologist and weeks 13-24 will be home-based (unsupervised).. Sessions will be generally conducted one-on-one with a maximum of 3 participants training at one time. All supervised sessions will be recorded on a clinical resource form and all home-based sessions will be recorded in an exercise log. Participants will be given a Polar heart rate monitor and taught how to monitor the intensity of their exercise sessions using heart rates and ratings of perceived exertion (RPE). All supervised exercise will be conducted on a treadmill, unless orthopaedic limitation exists in which a cycle ergometer will be used. Home-based exercise will involve walking/jogging or cycling depending on the access to exercise equipment and preferences of the individual participant.

Comparator / control treatment
Participants randomised to the control group will perform 12 weeks of stretching on three days per week and then be invited to complete the HIIT protocol. Stretches will be performed for all major muscle groups (e.g. calves, quadriceps, hamstrings, pectorals, neck, arms) and held for 30-60 seconds and repeated three times. Stretch sessions will run for 30-45 minutes. Sessions will be generally conducted one-on-one with a maximum of 3 participants training at one time. All supervised sessions will be recorded on a clinical resource form.

The HIIT protocol will be commenced after week 12 assessments and will be identical to the supervised HIIT protocol (12 weeks, i.e. weeks 13-24). The 12-week home based phase will be identical to that described for the intervention group (i.e. weeks 25-36)

On completion of the HIIT intervention, all participants (n=22) will be prescribed an on-going exercise program based on an equivalent type and intensity of exercise, modified for an unsupervised home/gym environment.
