Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Individuals will be asked to visit the Human Performance Lab at Massey University, Palmerston North on two occasions, 24 hours apart. During the first visit, individuals will have height, weight and blood pressure measured. Individuals will then be asked to provide a blood sample from a vein in their arm. Following this individuals will have their radial and corotid artery assessed via pulse wave analysis/velocity. Individuals will complete a 5 minute resting ECG. Each individual will then complete an incrememntal cycle ergometer test. Exercise commences at 0W and increased at 15W every minute until exhaustion. On completion of the exercise test you will be asked to repeat the blood sampling and corotid and radial pulse wave analysis/velocity measurement. Finally you will be asked to complete an exercise recovery questionnaire, SF36 questionnaire and the Multidisciplinary fatigue inventory-20. On return to the lab 24 hours later each participant will repeat the radial and corotid pulse wave analysis/velocity assessment, blood sampling, incremental exercise test, exercise recovery questionnaire and Multidisciplinary fatigue inventory. The approximate duration will be an hour and a half for the first day and one hour max on the second data. The tests are administered and supervised by an Exercise Physiologist.

Outcomes
Primary outcome [1] 293588 0
Peak oxygen consumption will be assessed via Turbofit metabolic cart.
Timepoint [1] 293588 0
Individuals will complete two peak oxygen tests, separated by 24 hours.
Primary outcome [2] 293645 0
Cardiac output will be assessed using the Defares rebreathing method and will be monitored using power lab. Individuals will be asked to complete two rebreathing samples at anaerobic threshold and at peak oxygen consumption
Timepoint [2] 293645 0
Individuals will complete two measurements of cardiac output at anaerobic threshold and peak oxygen consumption which will be separated by 24 hours.
Primary outcome [3] 293646 0
Pulse wave analysis and velocity will be assessed with SphygmaCor
Timepoint [3] 293646 0
Individuals will have pulse wave analysis and velocity tested before the exercise testing. Individuals will have pulse wave analysis and velocity retested 24 hours after initial testing.
Secondary outcome [1] 311415 0
Individuals will be asked to complete 6 questions regarding their recovery from peak oxygen consumption exercise testing.
Timepoint [1] 311415 0
Individuals will be asked to complete questions, following the initial exercise test, one day post exercise testing, following the second exercise test, day three (day after 2nd exercise test and then to describe how long it takes them to recover in days.
Secondary outcome [2] 311514 0
Gene response to exercise testing measured by blood samples
Timepoint [2] 311514 0
Individuals will provide blood samples pre and post exercise testing. Individuals will provide 4 samples across 2 days. The samples will be analysed to see how they change pre and post exercise testing.

Diagnosis
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At Massey University we run an exercise clinic for Multiple Sclerosis, so these individuals will be recruited through our clinic. Individuals with ME/CFS will be recruited through completion of an online DePaul Symptom Questionnaire.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Individuals will not be randomised into treatment/non treatment. All individuals will undergo all tests
Masking / blinding
Open (masking not used)

Sample size calculation.
Taking peak oxygen consumption for the CFS subjects, Standard deviation appears to be around 1.8 ml/kg/min, take 0.05 as the significance level. An improvement would be of 1 ml/kg/min and the power 80%. Therefore it is possible to calculate a sample size of 21 required.

The use of SPSS will allow for descriptive data on each health condition. Results of each health condition will be compared using T-test and Anova.

Summary
Brief summary
The purpose of the study is to show a difference in fatigue measured using physiological outcomes following repeated exercise in three groups of participants. These groups will include, Multiple Sclerosis, Chronic Fatigue Syndrome/Myalgic Encephalopathy and healthy age matched controls. Although individuals with MS, CFS/ME suffer from fatigue, it is expected that the type of fatigue and the way it affects the body is different and therefore the responses to physical incremental exercise separated by 24 hours will be different.
