Spinning elbows thrown by the Ultimate Fighting Championship's light-heavyweight titleholder move faster than the blades of a helicopter, ESPN says.

The TV network's Sport Science program recently measured the physical characteristics of Jon "Bones" Jones and confirmed what most fans of mixed martial arts already suspected: He's a physical marvel. Check out the segment below:

Jones is scheduled to face former champion Quinton "Rampage" Jackson at UFC 135 on Saturday (8 p.m. ET, spike TV; 9 p.m. ET, pay-per-view) in Denver.

It will be Jones' first title defense since winning the 205-pound championship in March.
