tonyzackery said:I've noted these posts with regard to 5sec power with interest. My athletic background before cycling involved American football. In my involvement, I've come across numerous ballplayers in the 80-90kg area that run the 40yd dash (speed metric) in 4.3 secs and less, vertical jump 40" plus (explosiveness metric), and standing broad jump 10' plus (explosiveness again). I personally was not one of them - but close.
tonyzackery said:Dr. Coggan, in your experience what would you estimate this composite athlete's 5sec bicycle power in w/kg? Would this athlete come close to or exceed 25w/kg?
acoggan said:Somewhat (but not entirely) as an aside: vertical jumping ability is more closely related to impulse (i.e., force x time) than it is to power (i.e., force x distance/time).
No idea of the exactly value, but again, there's no reason to believe that they would be over ~25 W/kg.

This would explain why I can't jump but I can sprint.![]()
I've noticed that it takes me a second or two into a maximal effort before I really feel like I am hitting peak forces. Almost as if my legs are slow to go maximal.

I do some weights, not a lot, I do find that it is hard to carry over gains from one discipline to another. Like, I'd increase my deadlift from 200 to 365, and I wouldn't notice a difference in sprints.
jsirabella said:I am sure that can be the same way in a sprint, an untrained person can see nice gains once they get the technique and motor skills down.

tonyzackery said:Not necessary to get pedantic on the issue, Doc. American football types (myself included) all understand the reasoning behind testing of the vertical jump, regardless if our understanding is just a little misguided...
tonyzackery said:Wasn't looking for an exact value; but maybe an educated guess. Nonetheless, I think this athlete could/would crank out some impressive 5sec. numbers in relation to athletes from other sports - cycling included.
I still haven't seen any data from any slow twitcher who improved their 5-sec power by greater than 20%. This post is specifically regarding an individual with high Type I fiber, not "anyone."velomanct said:Yeah and that's why I started posting on this thread. There are lots of gains to be made if people allow themselves to believe they can do it, and put their mind to it.

Paul;PaulMD said:I did it
But I am new to serious training since december 2006. After reading the "it's killing me" posts of Tyson I started to sport/cycle more. December 2006 I got my CycleOps Pro300PT. In Juli 2007 I got my first powertap for my roadbike. In the period july-september I had a personal best of 1008 watts for 5 seconds (with 73kg). At the end of september I started with weight training and as a warming up for my squat training (1 time/week) I also did 3 sprints on my Cycleops indoortrainer. During the winter my 5s power improved drastically (especially in the beginning).
At november 21th, 2007 I did 5s at 1207 watts (with 75kg)
At february 20th, 2008 I did 5s at 1215 watts (with 73kg)
And I don't consider myself as a fast twitcherI am still a non-sprinter and can only get those power numbers with a standing start. But lately I haven't done a single sprint as I stopped indoortraining and stopped squating.
john979 said:Paul;
I would respectfully submit that your results are consistent with somebody possessing a moderate amount of FT fiber who begins a program of "serious training." We are both approx. the same weight and I have never exceeded 900 watts, and I have 5+ years of data. Dr. Coggan's numbers are similar to mine, and he has 10 years of data.
I can take a biopsy (or let a colleague do it) and sent it to the laboratory herejsirabella said:Maybe the doc or someone else can enlighten me and let me know how do we really no someone is fast twitch or slow twitch. It seems to me that everyone has both types. Is there a more scientific way to see if someone is more slow twitch than fast twitch other than his results from a physical test?
Can we actually take a sample from someone or xray someone and they can analyze it? I have no idea and just grasping here.
jsirabella said:How did I know you were going to say that.
As soon as anyone sees the 5 sec power numbers go up passed 1,000 than they must be fast twitch. It is a winless argument as it will always go back to you are fast twitch.

On a different note saw your post about your ailment and hope you will be able to recover. Do not much about John but hope it all works out.

Hi John, I know that you are not trolling, neither am I. I now start too realise that I am maybe not a pure slowtwitcher.john979 said:Thanks for the comment regarding my health -- anyone know a good cardiologist with a sports medicine background in New York?
I am not a closed-mined person and I am not trolling here. I has also following's Paul's post regarding La Marmotte and from that, I know his FTP is 290 watts and current weight 68 kg or 4.26 w/kg.
Given a peak 5-sec power of 1215 watts and 68 kg, Paul does not have the power-profile of a pure "slow-twitcher." In fact, his comparative 5-sec power is greater than his FTP, indicating someone with "all-around" potential.
Paul;PaulMD said:Hi John, I know that you are not trolling, neither am I. I now start too realise that I am maybe not a pure slowtwitcher.
But I only question my FTP right now. My 20mp is now more than 332 watts, because during the second interval of a 2x20min training I managed to do 332 watts (that was on last sunday and the last interval was all out at the end).
I hope I can still do 1215w at 68-69kg but I am afraid my 5s power has dropped by stopping with the squat training. The 1215w is done at 73kg. Hmmz, I have to re-test my FTP and 5s power.
Maybe I am not the right person for a n=1 test. But I still think that with dedicated sprint training every slowtwitcher can improve a lot. But when the sprint is already trained for a long period, then improvements will be minimal. The same as a sprinter can improve FTP, but improve it less when he has trained it for a long period.
I read your mitral valve problem and wish you all the best. I hope you will find a good cardiologist soon. Did they find a course that caused the leakage? Can you still cycle or do you have also symptoms during normal activities or breathing problems when lying flat in bed?
Neither do I. I tend to get more improvement in 30sec-3minutes from large doses of L5/VO2 training, actually.john979 said:I don't see significant improvement in my 30-second power when I do 30-second interval training.
Can you explain what you mean by that? Do you mean in the sense of traditional peaking strategies, a lot of sprints and AWC work, etc?john979 said:I actually use these intervals to help peak my FTP.
Yesterday I did two sprints. My best 5s power was 1115 watts, i will try to do some more sprints at the next easy L2 ride. Difference between the "winter" sprints and the sprints I did yesterday is: 1.) outdoor vs indoor and 2.) my weight dropped from approx 73kg to approx 68.5kg now. A drop from 16.6w/kg to 16.3 w/kgjohn979 said:It would be very interesting to see what your 5-sec power is right now. It is probably a bit lower due to your focus on FTP but I bet still above 1100.
I have never trained my 30s power. Last summer mostly endurance rides. And this winter: 2-3x/week cycling on my pro 300PT with L3/SST/L4 plus 3x/week weight training (2x upperbody and 1x squat plus sprints, max 5-10s). Now I am doing more specific work for improving my FTP. I will do L6 after La Marmotte. After La Marmotte I am going to focus on my timetrial performance. I don't need sprint powerjohn979 said:Nevertheless, your power profile does indicate more fast-twitch ability than either Dr. Coggan or myself and Dr. Coggan did not see significant improvement when intentionally trying to increase his neuromuscular power and I don't see significant improvement in my 30-second power when I do 30-second interval training. I actually use these intervals to help peak my FTP. So now we have N=3.
That's a big suprise for me too. Do you have a link or a name of the first author and journal?john979 said:Data is important and as my personal knowledge evolves, I become more and more sensitive to science-based conclusions as opposed to belief or observational based ones, as much "conventional wisdom" is quite incorrect. For example, regarding VO2 Max, a very large study indicated that to a given controlled training program, there actually are responders and non-responders, the latter coming as a surprise to myself. More interesting is that there was nor correlation to initial VO2 Max and response, indicating that the genes that dictate VO2 Max are different from those which dictate VO2 Max response to training.
I wish you all the best and I hope there is a solution.john979 said:Currently, I am very interest in muscle fiber types and their influence on performance, IMHO an overlooked aspect which greatly influences limiters and is another reason why "anyone" can't do "anything".
Regarding my situation, I am actually glad I finally understand what is wrong with me and what has been wrong with me going back to 2005. 2003 was my first year with a PM and in 2003 and 2004 I saw a quite normal response to training. In 2005 things began to sputter a bit and I thought that was due to a new job and job-related stress. By the end of 2006 the job stress diminished and I refocused my training efforts, including purchasing a PT300 Pro. For three months I saw a steady FTP increase under a controlled TSS ramp with a CTL that was not particularly high, then out of nowhere my FTP dropped 10-15% and did not recover even with rest. I first thought my PT300 was defective but this was not the case.
The exact same scenario happened this year, almost to the day. This year I decided on full medical testing which revealed the MVR. There appears to be an acute side to it, exercise induced due to LVH. For now, I am going to completely back off on training, then determining if a medical solution is possible.
