Many years ago Loren Seagrave told me he thought one of the things he brought to athletics coaching was his insights and some movement ideas gained from his own background in ice skating: hockey maybe, can’t remember now. As an aside, when you go to Oslo you see lots of speed skaters etc walking in deep, slow lunges around the track doing their summer training for their ice season…
However, I do suspect the ice work may be of greater help to an athletics sprinter in taking the bend, rather than any other aspect of the track sprint.
