Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
The single full body resistance exercise session using machines and free weights administered individually by an accredited exercise physiologist. It will take approximately 40 minutes to complete 3 sets of 10 repetitions for each of the 6 exercises at 70% of 1RM. The 6 exercises will consist of three upper (supine bench press, lateral pull-down, seated upright row) and three lower (incline seated leg press, leg curl, leg extension) body exercises.

There will then be a seven day washout period before undertaking the aerobic exercise session.

Treatment: Other
Comparator / control treatment
One 30 minute session of aerobic exercise completed under the supervision of an accredited exercise physiologist will be completed on a cycle ergometer at 60% of VO2 max.

There will then be a seven day washout period before undertaking the resistance exercise session.
Control group

Primary outcome [1] 259480 0
Glucose variation using a continuous glucose monitor
Timepoint [1] 259480 0
continuous for 3 days post intervention
Secondary outcome [1] 266062 0
Insulin sensitivity using HOMA calculations from fasting glucose and insulin levels. Adiponectin will also be measured as a surrogate marker.
Timepoint [1] 266062 0
immediately post exercise & 72 hours post exercise
Secondary outcome [2] 266063 0
Aspirin resistance will be measured by separating some of the collected blood into two separate tubes, one containing a vehicle agent and one conataining aspirin before being analysed for platelet aggregation.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a randomised crossover trial. Concealed randomisation stratified by gender will allocate participants to complete the resistance exercise or aerobic exercise protocol first. An independent person, not involved in the research protocol will allocate using opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Resistance Exercise and Aerobic Exercise will be placed in a computer based random sequence generator. The sequence will be generated based on sex and in blocks.
Masking / blinding
