Heel or forefoot strike better? get angry...NOW! (Read 212 times)

    . For any animal, having claws that retract and extend requires muscles to do so. Not needing the muscles saves weight, which in the cheetah is applied to increased speed.

    Cheetahs have semi-retractable claws and do have the muscles there.

      Cats use the heel strike to maximize stride length and utilizing tendon elasticity.

       

      As someone showed earlier, cats do not heel strike. Their heels do not come anywhere near the ground when walking or running.

        How efficiently you run is determined even before you take your first step as a child.

         

        Now here's a good point.  Whether you have the DNA of a cheetah, ostrich, turtle, horse, or human makes quite a difference.

          Could talk to the effects of gene therapy to overcome being born human rather than ostrich?

            Are there any restrictions on this in USADA/WADA/nameyourorg rules?

              Patience, my friends.  While there is an obvious dearth of ostrich DNA in the human genome... there is nothing that science cannot overcome!

                    The comparison of a cat's trackways in contrast to a dog for example is how much of the metacarpal pad of felines are much larger than a canine's.

                    It clearly shows the difference in load bearing between the two species. Dogs, horses, and humans overstride. Cats don't. Cats are faster...

                     

                    I think you have those tracks flipped.  Dogs ALWAYS have claw marks.  Cats usually don’t.

                          Yeah, have you ever seen Mark Ruffalo try to make himself mad? It never works out.

                            When identifying animal tracks in the wild, a canid has claws showing, a feline doesn't; a quick and easy way to tell the difference between a coyote and a mountain lion, or bobcat. Yet the jester reverses this for his scientifical guesses. Since this is such an obviously incorrect assessment, we can discern from it that it WAS written by the jester, and not copied and pasted by an impostor.
