At recovery stroke stage the cross bridge cycle is the sarcomere is at.
The myosin head has a high energy profile and stores energy when stretched. As the myosin head moves towards the electric shock, this energy is dissipated. The myosin head is in the low energy position at the end of the locomotor journey.
After running on electricity, the ADP is energized; However, actin and myosin are linked together and the cross-bridge that has been built remains intact. ATP can then bind to myosin, continuing the bridging cycle and allowing the muscle to contract.
The recovery kick is the movement of the myosin head back to its original position. The myosin head in the muscle at rest holds ATP-derived energy until the next contraction. Because of the step by which force is generated, this movement is called Recovery stroke. The sarcomere shortens and the muscle contracts as actin is pulled towards the M line.
