wheather in case of martini protein cg the secondary structure of proteins remain fixed and also the helix changes during the simulation.

The secondary structure of proteins in Martini is fixed, and does not change. So it's the same as in the atomistic protein you gave to martinize.
If you want to see secondary structure chagnes in proteins you can't use Martini.
