Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After signing the informed consent form, an activity tracker (Withings Pulse HR) will be provided to all participants. After a four week observation period to evaluate the baseline levels of daily activity, participants will visit the LUMC for baseline measurements and a blood test. After obtaining these baseline characteristics, all participants will be randomly assigned to either AET, CBT or UC.
Participants in the AET group start with an intake meeting with a physical therapist. AET will consist of three weekly sessions of aerobic workouts on a bicycle ergometer for a period of 16 weeks. The first training session will be supervised by an experienced physical therapist at the LUMC. Subsequently, participants will perform the remaining workouts at home. One session per week will be carried out independently at home. The other two sessions will be digitally supervised via a digital connection by students, who will be trained and supervised by an experienced physical therapist. During the intervention, training intensity will be adjusted based on the participant's rate of perceived exertion (Borg Rating of Perceived Exertion (RPE) scale). During each session, the participant is also able to adjust the wattage of that specific training. Training activity and execution will be monitored remotely using the bicycle ergometer and the activity tracker. Adherence and reasons for possible non-adherence will be monitored by the students. Outcome measures will be collected on follow-up immediately after the 16-week intervention.
Participants in the CBT group start with an online intake meeting with a psychologist. The entire CBT program will be followed digitally through an online platform and will span 12-16 weeks. The program will be tailored to the individual participants' needs and preferences. Every week or every two weeks, the psychologist provides feedback on the finished sessions and gives new assignments. If necessary, the psychologist will contact a participant by phone for additional support. Outcome measures will be collected on follow-up immediately after the 16-week intervention.
The outcome measures of the participants in the UC group are obtained after the four week observation period and after 20 weeks follow-up. Participants are not restricted in their activities, but will be instructed not to start a new exercise or cognitive behavioural program. Chronic physical therapy and psychological counselling in the context of usual care are allowed to continue. After the 32-week follow-up, the participants in the UC group have the option to follow a modified version of the AET or CBT interventions without supervision.
Participants will be given the option to undergo a quantitative muscle MRI of the upper legs. The MRI is additional and not mandatory to participate in the study. The investigators will include a maximum of 10 participants per group. Participants will undergo the MRI twice: before intervention at baseline and after intervention at 20 weeks follow-up.
Furthermore, a qualitative study will be conducted to explore the experiences of participants in both the AET and CBT groups. Semi-structured interviews, based on a topic list, will be held with 10 participants from each intervention group separately. These interviews will take place within three months after the intervention phase has ended.

Study Groups

Aerobic exercise therapy
AET will consist of three weekly sessions of aerobic workouts on a bicycle ergometer for a period of 16 weeks. The first training session will be supervised by an experienced physical therapist at the LUMC. Subsequently, participants will perform the remaining workouts at home. One session per week will be carried out independently at home. The other two sessions will be digitally supervised via a digital connection by students, who will be trained and supervised by an experienced physical therapist. During the intervention, training intensity will be adjusted based on the participant's rate of perceived exertion (Borg Rating of Perceived Exertion (RPE) scale).
Aerobic exercise therapy
Participants will follow an aerobic exercise therapy program for 16 weeks.
Cognitive behavioural therapy
The entire CBT program will be followed digitally through an online platform and will span 12-16 weeks. The program will be tailored to the individual participants' needs and preferences. Every week or every two weeks, the psychologist provides feedback on the finished sessions and gives new assignments. If necessary, the psychologist will contact a participant by phone for additional support.
Cognitive behavioural therapy
Participants will follow an cognitive behavioural therapy program for 12-16 weeks.
Usual care
Participants are not restricted in their activities, but will be instructed not to start a new exercise or cognitive behavioural program. Chronic physical therapy and psychological counselling in the context of usual care are allowed to continue.
Usual care
Participants do not follow a program, but continue with care as usual

7. Ability to walk and exercise.
8. Ability to understand the requirements of the study and provide written informed consent.
Exclusion Criteria
2. The patient is unable to use the activity tracker and digital infrastructure provided.

8. Pregnancy or intention to become pregnant during the study.
Exclusion Criterion for muscle MRI 1. Inability to undergo MRI.
\- In case of uncertainty about the MRI-contraindications, the MR-safety commission of the Radiology department will decide whether this subject can be included in the study or not.
