You wake up in the middle of the night with a bad leg cramp. Earlier that day you remember an intense run, followed by the jump rope routine. What type of a spasm is that? Explain at the cellular level, what's going on in your leg muscle. Use the mechanism of muscle contraction, including the role of Calcium, to explain this type of spasm.
