muscle contractions: antagonistic muscle action Flashcards
1
Q
define antagonistic pair
A
as one muscle contracts the other relaxes
2
Q
what is the agonsit
A
the prime mover (muscle causing the movement)
3
Q
what is the antagonist
A
muscle that opposes movement of the agonist
4
Q
what is the rule of antagoistic pairs in the downwards phase
A
the agonist and antagonist switch
e.g. flexion at the elbow is usually agonist = biceps, antagonist = triceps
BUT
in downwards phase of a press up, agonsit = triceps, antagonist = biceps
