Re: Achilles tendon

Yes, fatigue is a factor as you noted.

If a muscle doesn't have the ability to absorb force as well, it will "jerk" down.

It's the same thing you see with tendonitis -- the muscle has poor input because of the pain -- so the motion is usually jerky on the eccentric which accentuates the forces placed on the tendon.

Hence, why tendonitis can often get worse very quickly.

It's a combination of factors coming together. High reps is definitely a factor too.
