Okay, I joined the forums hoping to get a push in the right direction from some of the great minds I see posting on the forums here. In short I have a roller skating related physics question. I am trying to figure out and prove whether it is faster, in order to gain speed from a dead stop, to do a hockey sprint style take off before transitioning into a stride, or if it is faster to run on the toe stops of the skates for a few steps before transitioning to the stride.. I have tested both physically and watched other skaters race using these two methods against each other. The one with the most skill in their preferred start is usually the winner, as I have seen both methods beat each other.. So my question is, how can I find and prove which of the two is actually worth training to get better at? There are many things to take into account and I am unsure what to do, as it seems a simple race has too many elements that rely on human skill for me to see from it which method holds the most practical advantages. Can anyone provide some insight on how to answer this? Thanks in advance.
