Coaching, jumps, sprints & more
Everything about jumping and sprinting and how to improve your performance
I'm pulling an interesting article together for Athletics Weekly (aka AW) on sprint technique and in particular the height of the heel in the recovery phase for both max velocity and acceleration phases of sprinting. here's a snippet to whet your appetite for the article which will be out later this month.
Contemporary sprint coaching has been placing a greater emphasis on a lower heel recovery or at least a different inflection on how the heel is moved back to front and how this is coached. We will first consider max velocity running and then acceleration.
If the heel is cast out too far behind the body when sprinting then frequency and power transference will tend to be reduced. You'll often see this in sprinters with a pronounced forward lean with "more work being done behind the body".
Key is the position of the foot and the gap between the heel and the bottom as the foot pulls through to the front. If the foot is pulled up as it should be for foot-strike (dorsi-flexed) it will come through to the front as a shorter lever and this will create greater frequency.
Doing this will also create greater power on ground contact, due to the fact that the foot (and leg) has increased velocity (angular velocity) which will in turn create a more powerful impact on the track surface and therefore greater energy return.
I found it really interesting exploring this aspect of sprinting and trying to make sense of what's more coaching inflection and thought rather than sports science based (particularly the case with max velocity phase heel recovery). I have long worked on heel recovery with the jumpers and sprinters in my group. In doing so greater hip power will be developed which is perhaps the real benefit of heel recovery work as the muscles to the front and the rear of the hips are the most important when it comes to sprint speed.
I'll be posting a video on this very shortly in the Sprint Drills series which is proving popular on my YouTube channel. In the meantime here's the latest video in the series which looks at what I call basic drills for specific conditioning purposes.
It’s pleasing that performances for the senior athletes in the group are coming together nicely in preparation for the World Trials. Two have qualified and hopefully another will for the event which takes place in Birmingham toward the end of the month.
I’ve found that younger athletes are able to produce good performances more randomly than senior ones. Probably because they are still learning … learning how to compete and how to use a new technique. Many are still growing and that’s going to have a big effect as well.
All the younger ones have achieved PBs this year and by younger athletes, by the way, I’m referring to those aged 12 to 17-18. The older ones have less ceiling for improvement particularly if they are training mature. I’ve also found that it takes more time for them to perhaps more mentally, rather than physically, get into peak shape. Take Paul and Sarah the two long jumpers, they’re now telling me that they are getting “on top” of their jumping. The speed and the coordination needed to take-off cannot come from training alone. Competition stress often increases speed through adrenaline and training can only take you so far. It can take time to “get your eye in” as it were. It seems that both Paul and Sarah are reaching this state of affairs. Both jumped season’s bests at the weekend gone (Sarah a brace of 6.24m’s and Paul 7.43m). Both also fouled very long no jumps, so fingers crossed there’s a longer jump to come very soon.
The central nervous system and the way it interprets signals is also key, there seems to be a fidelity to how this helps performance … it’s a bit like fine tuning. Remember those old radios which if I recall they had a button to tune into a station and then another to really get the signal crystal clear … it seems that reaching peak condition can be a little like that. There needs to be conscious and unconscious tuning in order to bring the physical and mental aspects of the athlete into a true peak. And of course there’s the effects of the competition itself and the value placed on that competition by the athlete and the way they respond to it. I’m hoping that at the trials all the fine tuning will come to a head and the guys will perform to their very best.
