Types of movement in ME/CFS: why walking can be easier than making a sandwich

Movement comes in many forms and each one affects the body and the nervous system differently. This article looks at two main categories: cyclic and acyclic movement. Each has its own pattern and its own effect on physical and mental health.

When movement becomes part of your day again it matters to understand which kinds exist and how they act on your nervous system. Just because my walking practice sits inside my baseline does not mean every kind of movement is equally demanding.

Slow walking in the evening works for me. Showering or making a sandwich is still far too exhausting and leads to a worsening. Yes, exactly: thirty minutes of walking cost me less than buttering a slice of bread, because the type of movement affects my nervous system differently.

Cyclic movement

Cyclic movements are repetitive, regular patterns that repeat in a steady rhythm. Jogging is a good example, with steps following a continuous and even pattern. This kind of movement has a calming effect on the nervous system. It can help reduce stress, regulate heart rate and quiet the mind. Cyclic movement is often connected with walking or slow cycling, which raise parasympathetic activity and support relaxation.

Acyclic movement

Acyclic movements, by contrast, are irregular and alternate between phases of high effort and lighter load. In weight training or interval work you go through intense phases followed by recovery phases. This kind of movement stimulates the sympathetic nervous system and raises the pulse during the intense phases. That constant up and down can create stress and put strain on the nervous system.

How to use this

I would invite you to observe your own movements and sort them into these two categories. To stay within your baseline it is decisive to record not only that you moved, but what kind of movement it was and how demanding it felt.

A pulse oximeter helps here, so you can orient yourself by measurable values instead of feeling alone. Your symptom diary is the place where those patterns become visible.
