    Salo was one of my lecturers on my degree course, and does a lot of work with the GB 4x100m relay team. He has been talking about getting this study published for ages – I saw rough results for this is 2007, so good to see it finally get published

    Interesting to see it studied. To really answer the research question that was posed, though – wouldn’t you have to look at whether the same athletes ran faster when taking quicker strides, or faster when taking longer strides?

    Seems like there are a lot of other variables (Time of year, What the competition was like, weather, etc) as well. I can only think of a few sub 10 guys (Montgomery is the only one immediately coming to mind) that took as many as 50 strides over 100m – and most of the sub 10 guys are down nearer 43-45.

    I’ve played around with it a few times when i’ve been testing fly 30m’s or something like that with gates. One run i’ll have very frequency and the other i’ll have long strides and the log stride run always produces the faster time for me at least.

    That is what they studied! Or at least, thats the data that I saw.

    You are right though, it would be subject to a great majority of environmental factors.

    Bezodis lectures at my university and I think Kerwin is based there to. Very interesting findings.

    I’ve found that my training on a single day can influence my SR or SL the following two days Due to neural activation. If I do strength, I feel like taking longer strides, bounds for examples, and faster strides result. So I can’t really know what type I am.
