"it thus appears that the elite pole vaulters
studied were more effective in performing the initial
programmed phase of the approach than a comparable
sample of elite male long jumpers. While there may well
be other explanations, it seems likely that this difference is
due to pole vaulters making more full-length approach runs
in trainingâ€â€

Only the first vault of the day, after the burn is gone from tearing the muscle and everything is stretched out I'm good to go 15"-28" under

P.S. I'm not proud of this ability....although it is funny sometimes when I check my step and cann't reach where I took off from hearing the comments from the other vaulters.
