Cognitive impairment in survivors of prostate cancer: combining cognitive and physical activity to target brain fog

The three training interventions will consist of 2 x 60-minute sessions per week for eight weeks, conducted on non-consecutive days. All training sessions will be supervised. Arm 1: Concurrent training For the concurrent physical and cognitive training intervention, participants will cycle on a recumbent cycle ergometer (CXP Target Training Cycle, Matrix Fitness, Australia) for 45 minutes (plus 15-min warm-up/cool-down) at a fixed intensity, relative to their cardiorespiratory fitness (peak oxygen consumption; VO2peak). During the initial week, participants will cycle at a power output corresponding to 65% VO2peak. For all subsequent weeks, the power output will be adjusted to achieve the same heart rate ±5 bpm . This approach will achieve a progressive adaptive overload (increase in the training stimulus as determined by power output) over the training period. While cycling, participants will complete a series of adaptive multi-domain cognitive tasks (including executive functions and working memory) using BrainHQ (Posit Science USA). The touchscreen and/or mouse utilised for responses (task-dependent) will be attached to the stationary bike utilising a customised desk attached immediately above the handlebar. The cognitive training tools from BrainHQ that have been selected: * Double Decision - Visual processing speed, selective attention * Target Tracker - Spatial attention * Mind Bender - Task switching, cognitive flexibility * Hawk Eye - Visual speed and attention * Juggle Factor - Visuospatial memory, tracking * Minds Eye - Visual memory, attention * Scene Crasher - Visual working memory * Eye for Detail - Visual processing speed, visual working memory Arm 2: Physical-only training For the physical-only training intervention, participants will undergo the same physical training as the concurrent intervention, except for completing the cognitive task. Participants will cycle on a recumbent cycle ergometer (CXP Target Training Cycle, Matrix Fitness, Australia) for 45 minutes (plus 15-min warm-up/cool-down) at a fixed intensity, relative to their cardiorespiratory fitness (peak oxygen consumption; VO2peak). During the initial week, participants will cycle at a power output corresponding to 65% VO2peak. For all subsequent weeks, the power output will be adjusted to achieve the same heart rate ±5 bpm . This approach will achieve a progressive adaptive overload (increase in the training stimulus as determined by power output) over the training period. Arm 3: Cognitive-only training For the cognitive-only group, participants will complete the same series of adaptive multi-domain cognitive tasks (including executive functions and working memory) using BrainHQ (Posit Science USA) as the concurrent training group. Participants will be seated at a desk to use the touchscreen and/or mouse utilised for responses (task-dependent). The cognitive training tools from BrainHQ that have been selected: * Double Decision - Visual processing speed, selective attention * Target Tracker - Spatial attention * Mind Bender - Task switching, cognitive flexibility * Hawk Eye - Visual speed and attention * Juggle Factor - Visuospatial memory, tracking * Minds Eye - Visual memory, attention * Scene Crasher - Visual working memory * Eye for Detail - Visual processing speed, visual working memory Those completing the cognitive tasks (cognitive only and concurrent group) will be engaging in tasks that involve the participant: -Responding to stimuli on the screen as quickly as possible -Tracking moving objects to assess divided attention -Challenging mental flexibility by processing changes in rules -Training their field of view visual precision which translates to how much information they can quickly capture -Keeping track of a sequence of moving objects and exercising intelligence by manipulating that sequence -Remembering what they see while ignoring distraction on the screen -Exercising visual memory by quickly taking in and remembering the details of a scene -Transitioning information from working memory (ability to hold what you see in mind) long enough to move it to long-term memory for better recall later. An Accredited Exercise Physiologist (AEP) will fully supervise physical activity assessments given the inherent potential for adverse events in the target population. Specifically, an AEP will monitor all assessments (including ECG surveillance during the aerobic fitness test), acting as an additional screening into the trial. An AEP/exercise scientist will supervise and oversee fidelity measures during the training interventions. Both roles are appropriately trained to monitor and handle adverse events (including first aid trained) with proximity to defibrillators (opposite our lab) and medical support (on-campus) if required. All participants will be recruited to this study under an ethical framework. In terms of adherence, upon arrival for any type of training session, participants will physically sign and date on and attendance tracking sheet that allows manual tracking of the sessions. This will also be captured digitally through and attendance spreadsheet.
