Conditions
Brief summary
The study aims to analyse the effect of cooling, combined pre-cooling and cooling during exercise, in cycling with a passive cooling vest on core body temperature, heart rate, balance, physical capacity and fatigue of individuals with MS and general people.
Interventions
Subjects will attend 3 visits in the duration of the trial. Exercise sessions will be one-on-one supervised by an exercise physiologist or physiotherapist. Visit 1 will determine each individuals maximum exercise capacity. Baseline assessment will be conducted on a recumbent bike. After a 5 minute warm up of cycling with no resistance, participants will begin to cycle at a low workload (30 Watts for MS patients, 50 Watts for controls). After each completed minute of exercise, workload will be increased by 10 Watts. Maximum workrate is defined as the wattage at the last completed minute of exercise. Visits 2 and 3 will occur on days 7 and 14, allowing a 7 day wash out period between experiments. Participants will exercise for up to 30 minutes at 65% of their determined maximum while wearing a cooling vest cooled to either 10 degrees or 21 degrees. The vest will be worn for 30 minutes seated resting prior to exercise and during warm up and aerobic exercise. All participants (both MS and controls) will take part in both conditions.
