What? Inverts are exactly the same G graph layout as sit downs. Flyers are different.
No.. Relative to the body's position they aren't. Sure, relative to the floor yeah. But it's the relativity to the body that matters.
Here, coming from a physicist, i know my stuff
MG is the force of gravity, and MRω^2 is the centripedal force of the loop. As you can see, the body experiences MG and MRω^2, but as the body is used to gravity and is built for forces in the downward direction, it's essentially just the force of MRω^2 being applied. No biggie.
Exact same concept with lay-downs.
The blood travels from heart to back in a flyer rather than head to feet, making it essentially safer. Again, no biggie.
Sit-downs are horrible because:
Unlike flyers or inverts, the body experiences both gravity and MRω^2 toward the head, the exact opposite to what the body is designed to do, causing a rush of blood to the head.
