Hummingbirds flap their wings around 70 times per second during normal flight...what is the fastest natural movement that humans are capable of, either voluntary or involuntary?

My daughter was watching a cartoon on PBS this morning and they were talking about pollination.  It was mentioned that hummingbirds are capable of flapping their wings upwards of 200 times per second.  After a quick google, it seems 70 is the more common number for "normal" flight.  That's obviously still extremely fast and made me wonder what humans are capable of in terms of pure speed, so I thought I'd ask here.

The National Science foundation released an article on the fastest articulated motion a human can execute, which is throwing. When an arm is cocked back it can store a lot of energy which is then released during a throw. The finger tips can reach over 100mph. A hummingbird flapping at 70 times per second with wing chord of 40mm and assuming it flaps in half a circle would have an average speed if 8796mm per second or about 20mph.
