I'm skeptical of the Super Hops idea. However even if it does work it can also be done with a loaded backpack and on the edge of a stair. With the same bouncing movement. I am still looking for studies done with tendons that show an increase in stretch reflex. I also think that through the course of proper plyometrics, strength training, and stretching the tendon will be just as if not more conditioned then with this exercise alone. I'd be interested if anyone has any scientific studies done on tendon conditioning and plyometrics response, or even other information on the subject.

I also think it is interesting how this technique is said to "lengthen" the achilles tendon and thus make it stronger. In other studies I found this:

"lengthening the tendon causes some weakness in the calf muscles, which can cause unsteadiness, but can be improved with calf strengthening exercises," Johnson says.

Lengthening achilles tendon reduces recurrence of diabetic f...( for six weeks to heal. After se...)

There is actually a surgical procedure to lengthen the Achilles to correct certain problems but they are saying the actual lengthening weakens the calf muscle.

I think the real issue is make the tendon more "stress resistance" and thus more reactive. I also think that the real trick to that is heavy weight in the gym which causes an adaptive response in the body for skeletal muscles, bones, tendons, and ligaments to better resist stress.

I'd love to nail this subject down though if anyone is game for it.
