Thanks. I agree on both points. While tightness is often a problem for me over the last 20 or so metres, in this particular race I felt rather tight from 30m onwards. Any thoughts on how to address the hip extension issue?
I would be curious to see you run some tempo 100s at a set effort counting your strides on each run. After you’re warmed up, continue to do more reps now stretching your quads between each tempo run and see if that affects your # of steps (hence hip extension).
What is your race warmup like?
I didn’t time these runs, but my SB for a flying 40 is 3.89s (timed using infrared speed gates)
According to my analysis, my stride length was the same for the 90 and 95% runs and slightly longer (ca. 2.5cm more) for the 100% runs.
I would say that hip extension looks a bit better from this angle than in the previous clip. Please have a look and tell me whether you think it needs improvement. (Before Asafa Powell came along I would have certainly thought it does, but now I’m not sure anymore.)
If you ran 3.89 for a flying 40m in training and ran 11.1 in a race I would focus more on your start & accel than your hip extension which looks ok to me.
Thanks. My start and accel is actually the strongest part of my race. Using a touch pad and infrared speed gates I ran 3.96s over 30m from blocks last week. Assuming a 0.15s reaction time at the start, that’s 4.11s FAT. Flojo split 4.09 on her way to her Olympic title (10.54)
Last year I ran 60m in 7.16 and one hour later 100m in 11.25, which suggests that the second half of my race is in need of improvement.
The 3.89 was in practice; 40m with a 35m run-up. I have run similar times in practice on three other occasions this season (3.91 for 40m and 2.93 and 2.94 for 30m).
The 7.16 and 11.25 were both FAT in a competition.
I ran a 6.93s 60m from blocks with touchpad last week, splitting the previously mentioned 3.96s at 30m.
Ok that makes sense. Like I said I was originally thinking 3.89 40m fly and 11.1hand.
Often, technical issues are resolved as your strength/power/conditioning/mobility levels go up. It’s hard to resolve a technical issue if you’re not capable of comfortably making the change. I see alot of paralysis by analysis that goes on when the problem’s root cause is that the athlete isn’t strong enough or mobile/supple enough to make the necessary corrections.
I think all your times are very logical. I am surprised you don’t get more benefit from a competition environment compared to practice. Oh and I wouldn’t go comparing yourself to the freakiest sprinter ever (flojo)
I think conditioning may have been an issue in my case, and I am planning to give a lot more emphasis to a (longer) GPP this fall/winter.
I think there are three reasons for this:
I train with a relatively low volume of sprint work (600-1000m per week) and thus do not get much benefit from a taper.
I often tighten up in races.
Weather conditions here in the UK (contrary to what my profile says, I’m not in Australia anymore) have been bad for most of my races this season. I did seven 100m races with electric timing this season and only one of them benefitted from both, a tailwind and temperatures above 20 degrees celsius.
Thanks for the link. I had seen it before, but wasn’t sure where.
your intial steps are short and no force coming off the ground… remember my key rule…
6steps to the first 10 metre in less time possible
also, there shud be more force coming off teh ground then going into the ground… watch ben johnson run 9.79… play attention to the first 30 metres… he was a monster at it…
I’m not sure how useful it is for someone who runs 11-flat to try to emulate the best starter ever when the strength and explosiveness is vastly different.
