Regular physical activity is known to reduce the risk for some neurodegenerative disorders and their symptoms. Several studies have shown positive effects of therapeutic exercise interventions on motor- and cognitive function as well as psychosocial benefits in persons with multiple sclerosis (MS). To improve exercise recommendations, it is necessary to learn more about the underlying biological mechanisms. A reduction of inflammatory stress through physical exercise has been suspected as one key mechanism, mediating the positive effects of exercise in the context of MS (being a "classical" neuro-inflammatory disease). This randomized controlled trial aims to investigate the influence of two different rehabilitative endurance exercise programs (3x/week moderate vs. vigorous endurance exercise) on (1) (anti-)inflammatory immune signalling and (2) various aspects of participation.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High-intensity Interval Training (HIIT) | Experimental | Participants of the HIIT group will exercise three times per week over a period of three weeks (inpatient rehabilitation) on a cycle ergometer. Exercise intensity will be regulated and heart rate controlled based on the achieved maximum heart rate (HRmax) assessed during the initial Cardiopulmonary Exercise Testing. Each exercise session will last 30 minutes and will be started and finalized with three minutes at low intensity (50% HRmax, warm-up / cool-down). During each exercise session, participants of the HIIT group will perform 5x one-and-a-half Minute high-intensive exercise bouts at 95-100% of their HRmax followed by active breaks of unloaded pedalling over 2 minutes with the aim to achieve 60% HRmax. |
|
| Moderate Continous Training (ST) | Active Comparator | Participants of the ST group will exercise three times per week over a period of three weeks (inpatient rehabilitation) on a cycle ergometer. Exercise intensity will be regulated and heart rate controlled based on the achieved maximum heart rate (HRmax) assessed during the initial Cardiopulmonary Exercise Testing. Each exercise session will last 30 minutes and will be started and finalized with three minutes at low intensity (50% HRmax, warm-up / cool-down). During each exercise session, participants of the ST group will exercise 30 minutes continuously at 65% of HRmax. This moderate continous training program represents the standard care at the local rehabilitation clinic. |

| Exercise Training | Behavioral | Treatment in both arms consists of specific of aerobic exercise training modalities. Exercise has become an efficient strategy within rehabilitative programs and is part of a goal-orientated multidisciplinary approach to improve disability and participation in persons with MS. Recently, short and exhaustive bouts of exercise have gained much attention as a promising option in supportive care in MS. |

Soluble factors that are known to be produced or secreted in response to (acute/chronic) exercise and are suspected to modify immune homeostasis and blood brain barrier function through their inflammatory and anti-inflammatory properties. (Tryptophan, Kynurenine, Kynurenine acid, Tumor Necrosis Factor-alpha (TNF-Alpha), Interferon-gamma (IFN-Gamma), Interleukin-6 (IL-6), Matrix-metalloproteinases-2 (MMP-2), Matrix-metalloproteinases-9 (MMP-9), Interleukin-10 (IL-10), Tumor Growth Factor-beta (TGF-beta), Interleukin-17 (IL-17) with higher values indicating higher levels of Inflammation. |
| Change from baseline (day 0) to directly after and 3-hours after the first exercise session (on day 0) and over 3-weeks (day 0 to day 21) |
| Migratory Potential of peripheral mononuclear cells (PBMC) | The migratory Potential of PBMC will be assessed by in situ zymography with higher values indicating higher Levels of Inflammation. | Three weeks (day 0 to day 21) |
| Endurance capacity | Endurance capacity will be measured by peak oxygen consumption achieved in the cardiopulmonary exercise test. Higher values indicate better cardiorespiratory fitness. | Three weeks (day 0 to day 21) |
| Assessment of Motor and Processing Skills (AMPS) | Processing skills of executive functions | Three weeks (day 0 to day 21) |
| Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) | Cognitive Performance is assessed with the BICAMS This test battery involves three tests to assess the main cognitive domains vulnerable to MS: information processing speed, verbal and visual memory. The battery includes the Symbol Digit modalities Test (SDMT), Californian Verbal Learning Test-II (CVLT-II) and the Brief Visuospatial Memory Test revised (BVMT-R). Processing speed is the most relevant test and is assessed by the SDMT where the patients have 90s to voice numbers as rapidly as possible that were associated with target symbols within a grid printed at the top of a Stimulus page. The final score is the correct number of substitutions in 90 s, and scores ranges between 0 and 110. Higher scores indicating better cognition. | Three weeks (day 0 to day 21) |

| Hospital Anxiety and Depression Scale (HADS) | Changes of anxiety and depression over three weeks training on a 4-point Linkert-Scale scored 0-3. Max 21 Points for each subsclae, cut off for anxiety and Depression are set at 7 Points higher values represent more anxiety and Depression. | Three weeks (day 0 to day 21 |
