A 2.5g weight is attached to the end of the isolated whole skeletal muscle used in these experiments. Simultaneously, the muscle is maximally stimulated by 8.5 volts and the platform supporting the weight is removed.
a. Will the muscle generate force?
b. Will the muscle change length?
c. What is the name for this type of contraction? A. The muscle generates force in terms of passive force in where the muscle does react to the electrical stimulus but the weight of the load pulling downwards would not allow the muscle to visibly move. The force is generated from stretching the muscle caused by the recoil of the tissue.
B. If the platform that supports the weight is removed, and the 2.5g weight is still connected, the weight would pull the muscle downwards causing it to lengthen. The muscle changing length would not be from the result of muscle contractions, but only from the weight pulling down.
C. This type of contraction would be Isometric
