The following refers to physical exercise and EEG:
There are some special technical requirements to record EEG during
physical exercise. Nevertheless, delta, theta, and beta bands are often
confounded by artifacts.
Alpha spectral density and the center alpha frequency decreases above
parietal and central areas. But since there are increments after
exercise, you cannot interpret
'alpha increases = brain activity increases'
'alpha decreases = brain activity decreases'
or the other way round.

I think brain activity and central nervous activiation are to be
considered as multi-dimensional quantities.
