Answer: yes, the syprahyoid muscles are the agonist.

They are the agonists because they elevate the hyoid bone while the antagonists are the infrahyoid muscles, because they do the opposite, they depress the hyoid bone.
The infrahyoid muscles are: the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscle.
