IPC protocol before: skeletal muscle StO₂ data in the ischemic preconditioning protocol at baseline; IPC protocol after: skeletal muscle StO₂ data in the ischemic preconditioning protocol at the end of the protocol; control before: skeletal muscle StO₂ data in the control protocol at baseline; control after: skeletal muscle StO₂ data in the control protocol after 60 minutes of rest; and ns: nonsignificant.
