Explain how wave summation and recruitment are achieved in vivo.

For Activity 6, explain how you were able to achieve smooth contraction at a given force level.

Increasing the stimulation rate causes smoother force production. Lowering the voltage (intensity) decreases the total force produced. Manipulating both allows the muscle to produce smooth force at any desired level. For example, increasing the stimulus rate while decreasing the voltage allowed the muscle to produce smooth force at a level of 2 gms.
