After a one-second contraction the content of ATP in the muscles both in vivo and in vitro increases with respect to the initial level and simultaneously the contents of creative phosphate and Pin decrease. 15 seconds after a four-second contraction the content of ATP in the both cases is below the initial level; in the isolated muscles it restores the initial level during the second minute of rest and subsequently does not change significantly. In vivo the content of ATP continues to increase, accounting for 114% of the initial level during the eighth minute of rest.
