Example showing effect of three sets of 10 kg standing loads for 10 s with 10 s intervals. A—IOP perfused with tourniquet applied, B—loading cycles, C—tourniquet removed at 5 min, D—loading during perfusion, E—perfusion stopped, and F—loading while non-perfused. Blue—serum perfusion, red—metacarpal diaphysis IOP, green—metacarpal epiphysis IOP. There is a progressive fall in IOP after removal of the load in all three perfusion states
