Define agonist (prime mover) and antagonist muscles. Describe and explain the differences that you observe in the EMGs recorded from the two muscles during different actions
Homework Answers
Antagonist and agonist muscles occur in pairs. As one muscle relaxes the other contracts. Which muscle relaxes or contracts depends on the movement. Consider a bicep tricep antagonistic pair. When the arm bends, biceps are antagonistic and triceps are agonistic. As trice contracts, bicep relaxes. In EMG when the contracting muscle shows closely placed peaks , the relaxing muscle shows an almost straight line with very small peaks.

Question 11. During a review of competition video, you observe that Mr Q is unable to maintain the orientation of his trunk during the later stages of his run (excessive extension in his lumbar spine and excessive lateral tilting of his pelvis). It appears that he is unable to use his trunk and hip abductor muscles to prevent that from happening. You decide to assess the control of Mr Q’s trunk muscles. a) List one (1) test that you would...
