CYCLING PERFORMANCE TIPS
Training should be specific for the competition being considered. A common mistake is to look at an event as a single ride, but any event can be broken down into several segments and specific modifications added to your basic program to address the unique needs of each of these segments of the event.
For example "Using the Kilo TT as an example, here is what I am trying to say. The most specific way to prepare for the kilo would be to go out and ride a Kilo every day, or every second day with a day of rest to allow us to adapt to the 'training'. Unfortunately (or fortunately depending on how you look at it!), this would probably become rather boring and that boredom (through the monotony of the training program) may indeed lead to overtraining (Carl Foster,Med. Sci. Sports and Exercise Vol. 30 No. 7 P1164-1168, 1998).
However, if you break the 1000 meter TT into its component parts:
We also know that riders get close to VO2max during the last 1/4 of the Kilo so general conditioning on the road which stimulates increased capillarisation, aerobic enzyme activities and increases in central factors (heart size, blood volume, red blood cells etc.) as well as intervals which target VO2max directly are also appropriate.
This separation into segments is to some degree artifical and these training segments are interrelated. For example, although the final 200m of a one kilometer event is anaerobic (ie a sprint), it is impacted by the training of the aerobic system. A highly developed aerobic engine will delay the time (even by a few seconds) that you will become anaerobic at the end of the kilo, and will minimize lactate levels until late in the ride. Thus a kilo rider, in this example, should train the erobic system to stall the negative effects of accumulated lactate as late into the event as possible. In this was VO2max and aerobic conditioning which improve the lactate threshhold overlap and impact sprint performance. Training only with sprints and failing to include some longer distance rides (longer than the "sprint" event) would leave you performing below your personal best.
But there needs to be balance, and too much compartmentalization in training can have its own negative effects. Andy Reid, also a PhD student in the School of Physical Education at Otago University, notes that training for both swimming and running have progressed over the last few decades from from a purely segmented (or compartmentalized approach with an emphasis on interval training working on one aspect of fitness per session back to a more "integrated" approach.
In one workout an athlete training under this integrated approach will include aspects of sprint training, specific endurance and general endurance. Can we apply this approach to the training of cyclists?? Consider this regimen. Add in at least one day per week of what we'll call "race practice sessions" that give a combination of
The above are good for the shorter sprint and time trial events, but what about the longer, perhaps multiday events? Chris Carmichael noted that the major breakthrough for Lance Armstrong occured when he stopped focusing his training on his anaerobic system (too many days of sprints/intervals and long rides at close to 100% V02max) and began to train his aerobic system. This allowed him to increase his AT, be "fresher" near the end of the race with less lactate on board, and as a result capitalize on his anaerobic capacity near the end of the race day. An added benefit was less recovery time from lactate build up and a stronger next day on the bike. Training too hard, too many days in a row can be as bad as under training.
This article supports the fact that maximizing training adaptation depends on the appropriate distribution of training time over the training intensity zones. Researchers compared riders based on the time spent in three different zones: Zone 1, below aerobic threshold (where you can happily spin for hours), Zone 2, which is between aerobic threshold and anaerobic threshold (or comfortably hard), and Zone 3, which is above anaerobic threshold (or where the suffering really starts).
Those who spent most of their training time in Zones 1 and 3 instead of Zone 2 enjoyed greater gains in their anaerobic power. This strategy of alternating between easy and very hard effort (avoiding the middle) is known as polarized training.
This is another well written article on training intensity balance. And for those interested, here is a link to the abstract of the original scientific paper. Although these are papers on running, the CV training benefits should be quite similar for cycling (and swimming).
So we know there are two pieces to the puzzle.
So 20% of your training TIME at a moderate to high intensity, a perceived effort of 6 - 10 or > 77% MHR. And 80% of your training time at a PE of 4 or less.
Now that you have the numbers, the challenge will be to keep those "slow and easy rides slow and easy. My guess is you will have to work to keep that HR down.
Buried in the middle of this blog is a nice practical suggestion on how to apply the 80/20 approach to maximize improvement. Do more than this and the there is little up side but significant downside. Although this is for running, I think the same approach can be applied to biking.
