Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised into an exercise group of either treadmill or cycle exercise.
Exercise will last for 45 minutes (moderate intensity at 65% of VO2peak) and will last for 10 sessions over a two-week period at the Murdoch University exercise physiology laboratory.

An oral glucose tolerance test will be completed pre and post-training with blood samples taken every 30 minutes. Blood samples will also be used to measure immune related cells such as regulatory T cells.

Familiarisation will preceed training with a VO2peak test, body composition analysis and anthropometrics measured.

Exercise will be supervised by the PhD student who is running the project.

Outcomes
Primary outcome [1] 299376 0
Glucose tolerance via oral glucose tolerance test (75g glucose).
Participants will ingest a 75g-carbohydrate containing drink in a fasted state.
Timepoint [1] 299376 0
Pre and post two week training period.
Blood samples will be collected pre-ingestion and every 30 minutes for two hours.
Secondary outcome [1] 326979 0

Efficacy
Statistical methods / analysis
Analysis of variance with repeated measures comparing within and between groups..
Based on Nieman et al. (Brain, Behaviour and Immunity, 2014 DOI: 10.1016). 20 participants will provide 80% power accounting for drop out to detect a difference in IL-6 marker with the a-error probability set at 0.05; f=0.875. This sample size was also increased as other markers will also be measured.
