Should all athletes training for a given event prepare in the same way? I expect most readers of this blog to answer that with a resounding “no.” It’s fairly obvious that if your intent is to win the race you will train altogether differently from that of the athlete whose goal is to simply finish the event.
Advanced athletes shouldn’t train the same way as novices. A novice athlete can do almost anything in training and they will improve their performances. A newbie triathlete getting ready for a sprint triathlon can only lift weights for several weeks never swimming, biking or running and improve their performances compared with doing nothing at all as they had done prior to “training.” On the other hand, advanced athletes cannot afford to make mistakes in training if they have high performance goals. But they often do. Let’s look at just one example of this. In Part 2 I’ll examine another way of training which has recently been shown to benefit advanced athletes, but not novices or those less-well-trained.
It’s been well-established by research that while emphasizing the volume of their training produces dramatic improvements in novices, doing so with elite athletes has little or no benefit beyond a certain and easily achieved point. However, high-intensity training, especially intervals, has been shown repeatedly to significantly improve the performances of elites in endurance sports [Lindsay, Westgarth-Taylor, Weston, Kubukeli, Laursen, Laursen, Midgley].
For example, researchers at the University of Copenhagen studied the effects of volume vs. intensity on 17 experienced runners [Bangsbo]. The runners were divided into two groups. One group reduced their training volume by 25% and did 6-12 x 30-second sprints 3-4 times per week for 9 weeks. The other group of runners continued training as before with a lower average intensity and a volume of about 55km per week for 9 weeks. At the end of the experimental period there was no change in the aerobic capacities (VO2 max) of the runners. However, those who ran sprints with reduced volume improved their 10km race times from 37:20 to 36:18—they were 2.7% faster. There was no improvement in the higher-volume, lower-intensity group. The results of this study are similar to what is typically found in such research.
Certainly some events are more volume-oriented than others. Training for an Ironman triathlon usually requires more volume than training for a one-hour criterium bike race. But volume is not the key issue here; it’s duration. If you are an advanced Ironman triathlete who is focused on how many hours, miles or kilometers you accumulate in a week then you’re missing the point.
I’ve said this so many times that I’m thinking about making it the name of this blog: The closer in time to the race, the more like the race your training must become. In the last 12 weeks before any event—Ironman or criterium—it is the interplay of individual workouts, not your weekly volume, that determines how well you will race. But the individual workouts in preparation for an Ironman are necessarily longer than what’s required of workouts in preparation for a crit so this results in greater volume. But it’s not the volume that determined the outcome; it’s the individual workouts. In the last 12 weeks Ironman as well as criterium workouts must be not only duration-specific but also intensity-specific. Intensity is no less important for the Ironman than for the bike crit racer. And both can do workouts that are longer than their race or race split. But neither can maintain race intensity for longer than race duration if they intend to race at maximal effort.
Bottom line: If you’re an advanced athlete and in the last 12 weeks before your A-priority race then you had better be doing intensity-specific workouts and disregarding your weekly volume.
In Part 2 I’ll take a look at periodization for the advanced athlete.
