Primary Outcome Measures

Name	Time	Method
The primary outcome for this study is the associations between changes in sleep (measured via WatchPAT) and changes in cognitive function (on the cogstate cognitive battery) due to an acute high intensity exercise intervention. [Objective sleep measurement (WatchPAT) completed at baseline (5 nights of data), the night after the intervention, and the night after the control. <br>Cognitive function (cogstate) completed at baseline, immediately after the control and immediately after the intervention, and 24-hours post control and post-intervention.<br>];The effect of acute exercise on cognitive function (measured via the cogstate cognitive battery) immediately post exercise. [baseline - post intervention session<br>baseline - post control session ];The effect of acute high intensity exercise on objective sleep (measured via WatchPAT) the night following exercise[baseline - post intervention session<br>baseline - post control session]

Secondary Outcome Measures

Name	Time	Method
Reliability of the cogstate cognitive battery assessed by analysing the consistency of results on outcome measures across the three baseline assessments. [Triple baseline assessments (separated by approximately 7 days)];Reliability of a cycling based maximal fitness test in older adults by examining the intra-class correlation between the results of the two assessments. [Double baseline measure (separated by approximately 14 days)];Practice effects on the cogstate cognitive battery. These will be assessed by examining the change in performance over the triple baseline assessment.[Triple baseline assessment (each separated by 7 days)]
