To train acceleration for (American) football, I would start in the usual wide receiver stance and do 10, 20 yard runs, and up to perhaps 1 or 2 30 yard runs at the end.
However, for soccer, we don't start in the usual WR stance when we start running. We are usually jogging already or we will be at a stop/walking. Then when the ball comes our way, we start sprinting.
I am wondering if it is optimal to train acceleration starting in the WR stance. I am thinking of changing to the two point stance as shown in the picture below. The problem is that I do not know if it is optimal. I think that if I train in the WR stance, I will have a slow acceleration due to not being in the right position when I start running. However, I am sure I am much faster beginning in this stance. I am not sure, and I come to ask.
So, the question in short: Should I train acceleration starting in the WR stance or the two point stance as shown below (look at the white jerseys)
EDIT A third option I just thought about is to do the WR stance and emphasize one-legged exercises when weight-lifting.
