Some models allow the user to pedal backwards to exercise antagonist muscles which are not exercised in forward pedaling.
Part of the training process is learning to relax the antagonist muscles to increase the force input of the chest and anterior shoulder.
To allow this reflexive contraction, the antagonist muscle must lengthen.
Such complementary muscle groups are termed antagonist muscles.
Heteronymous inhibition has been found to be dominant in the leg compared to the arm, where antagonist muscles work simultaneously.
Electrical stimulation to the antagonist muscles or vibrations has also been used with some success.
Splints are used in long term treatments and must be removed in order to stretch the antagonist muscle to maintain range of motion (passive stretching).
By disabling the movement of the antagonist muscle, the agonist muscle is allowed to move freely.
In biology, a tremor is when antagonist muscles move repeatedly without being controlled.
A small device that can help in developing the antagonist muscles to those used while gripping with the hand.
