Hi 
As an avid skydiver myself with more than 60 jumps under his belt and 2 implants in his hand (one being glass and the other being flexible )
I can assure you that nothing will happen to the implants.
Also i never felt anything change during a jump.
But tbh that can also be because of the adrenalin pumping trough me when i jump out of a perfectly working airplane 
Have fun skydiving
