Off-Season Training: The Need for Intensity?
After resting off the bike to recharge the batteries and reviewing your past season, it is time to start planning the off-season training and priorities. One of the big questions about the off-season is the “need for speed,” namely how much intensity or resistance training work is required or beneficial.

THANK YOU!
Before we get on with this week’s Toolbox, I must take time to thank all of the loyal Pez readers who have written to me since reading about my bike-car accident in late August. The heartfelt good wishes, the sharing of battle scars, and the similar determination to get back on the bike and the sport we love, have really been a huge source of support to my family and me during this difficult period. It’s incredibly cool being part of this big cycling family through Pez!

Despite some hiccups, I’m recovering steadily, to the point where my first road ride is tantalizingly close to reality! I’ll be writing about different aspects of my continuing recovery over the next little while, and I’ll be doing my best to write back to each and every one of you who have written to me.

There is no Off-Season
Let’s explode the myth of the “OFF” Season. While there is certainly a necessity to take some time off the bike, I much prefer to get away from the term “off-season” and its implication that it’s time away from serious training. The obvious cycling example is Armstrong vs. Ullrich.

Ullrich is famous for packing on the weight, with the result that much of his early preparation involves workouts designed to get rid of the weight. In contrast, Lance rarely “relaxes” enough during the winter to gain more than 2 kg or so of weight, allowing him to get back into high-quality training quickly. In turn, this sets him up for improvement year-to-year rather than always just managing to get back to the same level each year.

Looking at other sports, the same pattern of maintaining close-to-peak fitness is consistent. For example, elite swimmers are typically NEVER more than 5% off their peak fitness or their performance times throughout the entire year. Dropping any further simply requires far too much time and effort devoted to rebuilding, with the result that your growth and improvement over the course of the year and year-to-year becomes limited.

LSD, Anyone?
During what I prefer to call the “Non-Competition” season, training may incorporate many of the alternative training modes that we’ll be discussing in the coming months, such that the actual time on the bike will likely decrease slightly. However, the concept of training specificity dictates that it remains critical to continue logging bike time to maintain muscle memory along with maximizing cardiovascular and metabolic efficiency.

With this in mind, one theory of training suggests that the primary goal of the winter months is to log large volumes of low-intensity (often called “long steady distance” or LSD) training on the bike in order to build a large aerobic capacity for subsequent high-intensity training in the early racing season. This advice typically includes warnings to avoid high-intensity work on the bike and/or resistance training at almost all costs, as it might somehow ruin the benefits from the aerobic-based training.

Get Intense!
Make no mistake – cycling remains an endurance sport, and a strong aerobic capacity remains the foundation for success in almost all cycling disciplines. However, the latest scientific evidence suggests that there remains a place for high-intensity work even during the winter months. This was highlighted in a review published online in 2004 at the excellent website www.sportsci.org.

The authors, Carl Paton and Will Hopkins, surveyed the existing 22 studies in the scientific literature investigating the use of high-intensity and/or resistance training using elite athletes as subjects (1). This is a key approach, as it eliminated a lot of studies using recreational or untrained athletes, where the addition of almost any training manipulation would lead to significant increases in performance.

Furthermore, the high-intensity training studies were further categorized into “sub-maximal”, “maximal”, and “supra-maximal” studies, while the resistance training were categorized into “explosive sport-specific”, “explosive non sport-specific”, “plyometrics”, and “usual weights.” (See Table 1).

Analyzing the Studies
As always, there are caveats to keep in mind when reviewing any scientific data. First and most important that we’re talking a total of 22 studies over all of these categories, so some of the findings may be skewed by the fact that they come from only 1-2 studies. However, some general trends appear:

• Short but maximal intensity efforts (at power outputs near that at your VO2max) and above seem to be the most beneficial. Paton and Hopkins (1) theorize that this is due to stimulation of the most metabolic pathways (alactic, anaerobic, and aerobic).

• Explosive type resistance training, stressing rapid movement of relatively light weights, seem to have the greatest benefit.

Extending the concept of specificity, look at these findings this way – the effort required to sprint at, for example, 1000 W, is very specific in terms of metabolic and neuromuscular demands. If you spend 6 months not stimulating and forcing your body to this level of effort, you will “detrain” from being able to handle this effort, and will spend a lot of time and effort building back up to this level. In contrast, just a small amount of stimulus may be enough to maintain these gains throughout the non-competitive season, allowing you to build and progress year-to-year.

Resistance Training In-Season?
The other common training dogma is that resistance training should be minimized or eliminated during the competitive season. All of the 22 studies in this summary had the additional training performed during the non-competitive season, and it can be argued that the benefit observed was simply due to putting high-intensity training where there was none previously. However, one study by Toussaint and Vervoorn (2) implemented explosive resistance training in elite swimmers during the competitive season, on top of the already extensive high-intensity training, and still observed a small but significant improvement in performance. While this is only one study, this suggests that explosive resistance training is beneficial throughout the year.

Summary
As mentioned above, the key caveat is that 22 studies is still relatively low numbers to draw conclusions from when we’re dealing with so many possible training manipulations. In conclusion:

By no means is any of this suggesting that you toss out aerobic training and simply do VO2max efforts every ride throughout the non-competition season! The main conclusion from Paton and Hopkins’s review (1) should be that there is potential benefit from SMALL amounts of high-intensity efforts supplementing the aerobic training.
