As efforts increase in duration from 10 seconds there is a greater amount of energy from aerobic energy systems. Realy any effort over 1 minute could be seen as an aerobic activity given that most of the energy for that activity comes from aerobic sources. Although, quite often its the anaerobic capacity of the riders that decides who wins.Originally posted by Jonny
The current Bicycling Australia Magazine has a good article on what it takes to ride the kilo.
I had a quik browse of it in the newsagent. It said something about almost a 50/50 split in anaerobic/aerobic energy systems.

To break the world record you need to average 60km per hour for 1 minute. As you ride from a standing start, peak speed will be above 60km per hour. Although he can hold 34 mph for a minute, it might be the case that his 'race is over' by the time he hit 30 miles per hour. Some of the GB guys are getting 1 min 1 seconds and they are performing very quick (I think 17 second off the top of my head) 250 mtrs off a standing start!Originally posted by TTer
As VeloFlash said, that speed would make you a good (even great) Kilo rider! I can't believe you can accelerate *staying seated* and quickly get up to and hold 34mph for 1minute. Even the Kilo guys stand and hammer it. Is the road you use slightly downhill 1-2%?
The three phases you describe are typical of maximal work and correlate nicely with anaerobic metabolism.Originally posted by J-MAT
I decided to try those hardcore, "all out" VO2 intervals using this section of road to start with. This spring, I was lucky to hold 30 mph for the distance. 34 mph represents my best average for the distance, but I will start to fade at 45-50 seconds or so usually. Some days it might only be 32-33 mph. There are three distinct phases to the first 60 seconds: The initial acceleration, maintaining speed, then the fight to maintain speed. At the end of the "fade" I downshift and transition to a much slower pace for several more minutes.
Perhaps I have read you wrong, but IMHO a few maximal 60 second efforts wouldn't be 'the best way to improve VO2 max' rather it would be a 'good' way of impoving anaerobic capacity (given that the work performed specificaly targets this).Originally posted by J-MAT
Most riders don't train this way, but I like it!!! I think this is the best way to improve VO2 max.

Actualy, you are trying to accumulate as much time as you can @ VO2 max. Given that it might take your body (HR and o2 consumption) to reach that level, you need a few minutes to reach a relative 'steady state' at that level. Whether your effort is 3 mins or 20 mins, the intensity at VO2 max is always the same! The effort should be at the same intensity for the whole duration (i.e. power at VO2 max or HR near to max).Originally posted by TTer
Is 3 minutes the minimum time necessary to improve VO2max? Obviously they will be higher intensity efforts than 6minutes? Should the effort be such that you can (only) just manage to complete the interval with legs burning and form starting to go off a little (not too badly though)? Or is that too intense?
DG's session would also improve VO2 max, but I would argue that a more controled session would be better as it would be less demoralising and you could spend more time at VO2 max due to less fatigue. If you do a constant load session, the aerobic energy system is maxed and added to slowly by the anerobic system. DG's session you fatigue the anaerobic system and try to keep the aerobic system maxed (which may be hard due to local fatigue in the muscles (i.e. acidosis)).Originally posted by TTer
What's your opinion on Dean Golich's method of starting these VO2max intervals with a flat out sprint, gradually fading as the effort goes on, but pushing constantly to maintain the highest possible wattage? Some coaches say maintain an even effort that you can only just maintain for the duration, Golich (and some CTS coaches) say an all out sprint start held as long as possible. What would the difference be?
Yes there would be differences due to the recruitment of the different energy systems in different ways and the specific conditions within the muscles (e.g. different lactic acid, neuromusculr fatique, etc.). During both sessions all of your muscles fibre populations would be recruited and as you fatigue this recruitment (i.e. EMG) would increase - I wouldn't worry too much about muscle fibre types as you can't change them and you can't isolate them during training.Originally posted by TTer
Would there be any difference in muscle fibre recruitment/training with the two methods, or are both utilising fast-twitch muscles because of the hard VO2max efforts? Or will only Golich's method utilise the fast twitch muscles?
J-MAT, this thread is about the 1km TT on the track and this is a sprint event from a standing start lasting 1 minute for world class riders to about 1 min 20 seconds for riders with some training.Originally posted by J-MAT
TT'er, everybody:
Just so there isn't any confusion about these posts on the kilo, I'm talking about doing these 60 seconds efforts as the first part of a 3-5 minute VO2 max interval.
DG is known for these types of intervals, and where I got the idea for them. They are hard but very simple.
You can start with an out of the saddle sprint if you like and really go "all out" to start (10-20 seconds), then settle into whatever pace for the duration of the interval.
I start from a roll to make it easier on my left knee and modulate the effort over roughly a minute. Whichever way you do them, the idea is to blow up and crack completely, then keep the effort going.
These intervals overload the CV system so rapidly that the subsequent slower portion of the interval at whatever speed still places a huge demand on the heart as the body tires to recover.
Effort is most important, speed is not. Even if you are only going 10 mph, as long as you are breathing rapidly and working at your limits, you will make excellent progress.
You can improve VO2 max other ways, but these are very effective, possibly the most effective, even though mean power output may (or not?) be less than a "normal" 3-5 minute effort.
DG also likes 3-5 day blocks. Doing just one (max quality) of these intervals every day for 3-5 days in a row in conjunction with some sustained TT efforts of 20-60 minutes would form a very potent training stimulus. Recovery is paramount at all times, especially when training like this.
Man, just try them and see how it goes. I think you will find them refreshing compared to "regular" intervals, and will improve your performance. They will also help maximal FT muscle recruitment and development that lower intensity intervals won't. Hard sprints maximally recruit FT fibers.
It's also refreshing to know that you can accelerate to well over 30 mph, hold it long enough to drop most if not all riders, then settle into a sustained high pace that the dropped rider(s) will never come close to. Perfect for dropping those pesky breakaway companions, especially if they can sprint!!!
No matter how fit you are, if you don't train like this, you will have an extremely difficult time staying on the wheel of a rider who does train like this when he attacks.
DG coached Norm Alvis (U.S. hour record holder) and Mari Holden, (world TT champion). To hold either title, you obviously would have to have a very high VO2 max. Could these "flat out" intervals have been the key to their success??? Perhaps!!!

Thanks for telling me what a "track" and "kilo" are. I had no idea people actually rode their bicycles on a "track." Very interesting, you learn new things all the time!!! Maybe someday I will go to one of these "tracks" and see what the riders do on them.
You might have noticed the thread changed a bit. TT'er was talking about Dean Golich's flat out intervals, and I do a hard 60 second effort to start which is somewhat like a kilo effort.
Surely, you can see the direction the thread has taken. It's not really about the kilo anymore as much as it's about improving VO2 max which the DG intervals performed the way I describe will do very nicely.
