can you tell me which part of CF helped? I have some mixed feelings on some of the info. I am not sure that the info provided helps with acceleration.
At what point do you just write off the 100 for a kid? She loses 10m right out the gate to everybody. IF she can stay close enough in some races and stays loose, she will get back in it. SHe does relatively well in the 200. I am starting think she is a better 200-400 girl.
Where I coach HS track, 11.8 is really fast, 13.5 is really not. I realize she is just completing her frosh year, but is there something about her that makes you think sub-12 is a realistic possibility? I have a frosh girl who ran 13.2 in her only 100 race and I have no reason to think that her future is at that distance. 400 (and maybe both hurdles) for her, and maybe for your girl, too. Do you have a 200 time for her?
If you want to do well in the 400 for a girl, the appropriate training will improve the 100 as well.
I also wonder how judgements can be made about potential without knowing growth patterns etc.
The answer really does not come from a single part of CFTS but rather many components in the entire system.
There are many tools in the program which positively impact acceleration such as actual short sprint work from various start positions along with block work, hill work, and other forms of resisted sprinting, med ball throws, various jumps/plyos, wts., as well as an emphasis on proper technique throughout training etc.
I agree completely, and the work she does will serve her well at any sprint distance, because I am basing it on your principles 
. So if 100 is her future, we should see it. But given her level of maturity now, I am just not counting on it; and she doesn’t like 100 anyway. Of course, if she ran sub-12, her view would likely change.
The clip below is an example of what I’ve taken from CFTS, Forum Review and GPP Essentials.
Many on here probably do some things differently. However, I’ve been quite fortunate to learn and apply accordingly with relative success.
And what is it about this clip you learned? 
Dido!
Is that a resisted sled she is pulling?
Resistance cable from a stationary post. The process was one aspect of improvement in acceleration.
wow 11.93 she should smash that with ease. What state is that?
Midwestern US. Stop with that already, I know it is not that impressive. I am working on it okay, give me time. Truth be told, I have 4 other sprinters who are much closer right now.
How much would you say the stationary resistance band helped with the 60m time?
Hey, I would about kill for a girl near 12.0. Are you under 50 for 4X100?
First let me say that we use the Isorobic Exercisor on grass as well. However, in some cases I found the resistance cable to be helpful in track acceleration work. We generally go 10-15m with it. We use another apparatus to go longer with other athletes, if necessary.
To your question, we’ve only taken it to 40m. The biggest difference with this process has been improved body positioning which has allowed for a recent 0.1 slice off her time between 20-40. I will be quite curious to see in the coming months if this will also affect improvement in the 50-60 segment.
Actually, we set the record a few years ago in the girls 4x100 and 4x200. 47.95 (w/ a poor 1st exchange), and 1:40.76. We had very little push in both relays. One of my sprinters on both relays had a 11.73 best in the 100 and a 24.51 in the 200 and stood only 4’7 roughly. That helped a lot.
So how is the state record not 11.73?
The fastest overall time in the state for sanctioned HS sports in the 100m for girls is a 11.93.
You can only set the state record AT the state HS championships in order for it to be official because the state (trained) officials, wind gauge, and everything else is at this meet. It is also at the sectionals but I guess they still won’t count it. My girls ran a 47.27 4 weeks before the state meet unofficially and hand-timed (by six different people; give or take a tenth or two). Not counted however due to the state officials not being there. I guess it has its good and bad sides to it.
Lastly, my sprinter ran her personal best during summer track. HEr best under my tutelage was 11.91 during the school year.
Does that make sense?
