When I do 60m sprints my knee lift starts to drop after a couple reps and I feel like am decelerating. On the other hand I see this with maurice greene after the 60m but his splits show minimal deceleration. Does this mean that one can still maintain top speed as knee lift drops?
help anyone?
Are you pushing out the back?
i dont have that much of a backkick
Posting a video would help more than describing it.
I don’t have a video, but this is what am talking about, as you see maurice greene passes ato boldon with barely any knee lift, and doesn’t seem to slow down as much.
You can’t accurately guage an individual’s deceleration pattern by watching his position relative to others who may be decelerating more or less in different races but check the Rome film and compare it to the Athens WR film and compare the knee lift.
In both films there is more lift on the right than the left side to compensate for torso movement but it remains relative and, clearly, there is more knee lift when he’s going faster in Athens.
Film angles may hide part of the story as well because hip height is key and that is difficult to discern unless the film is directly from the side in both cases.
thanks CF. the athens race does have more knee lift and better maintenace from 60m - 100m. Does this mean that high knee drills, A and B skips for longer distance might support maintenace?
It might but ultimately there is a pattern to improvement. First you get fit then you work on technique and move progressivly to speed and power. Depending on where you are on the performance spectrum will decide which strategy is best for you at this point in your development.
BTW knee lift is rarely to 90 degrees in any level athlete. Obikwelu is one athlete with very high knee lift.
