Certain types of Long COVID tend to be more prevalent in healthy people.

Otherwise, there is no increase in prevalence among overweight people, but a trend toward athletic people and people who did not, or could not take time off to recover from COVID before going back into an active life or exercise regimen.

The dysautonomia type of long COVID (which encompasses, chest pain, palpitations, shortness of breath, and inability to exercise) tends to be more profound in athletic people who had previously conditioning themselves to have better cardiovascular fitness (and therefore had lower resting heart rates, and less rise of heart rate during exercise).

There is a relatively close association with mental health concerns like depression and anxiety with Long COVID - particularly the neurologic type of Long COVID as well as the Dysautonomia type (dysautonomia being an issue of the autonomic nervous system)

So aside from underlying psychologic comorbidities, it seems to be more prevalent in healthy active individuals.
