Bode said:Yes, it is a natural enough movement for the average joe to do instinctively. The push is impossible to perform without the inherent index. If I am pushing a relatively flat surface such as the chest of a human, it requires me to flex my wrist, pointing my fingers towards the sky, and extend my arms. People don't push with their elbows collapsed to their body. Their instincts will tell them this wont work and they will extend their arms. So certain index's are a byproduct of human evolution and making the most out of our physical frame. I.e. having the most power in a push.
The major differences in attack will not lie in the index or not indexing of the hand/arms, but in height, angle of attack, body mass, etc...
OK, that's the kind of answer I was looking for.
I will say, however, that when I want to give something a good solid shove, I will sometimes bend my elbows downward and brace them against the sides of my torso, and engage my whole body into the push. If I was trying to do this to a person, I think I might do it this way as well, or I might do it with the arms more extended. I think for me, it might depend on the circumstances. The bent-elbows braced method might be faster at a short distance, and would come in under the radar and be a big surprise for someone who's attention is focused high. Might be an effective sneak attack. Of course a proper sneak attack is difficult to defend against for that very reason. Just my own thoughts based on my own experience.
