It would be foolish
to suggest that physical performance is determined by a single factor.
At the same time, it is important to understand that physical performance
is subject to a 'weak link’ principle. At any point in time, your
performance level will be limited by the weakest link in the interacting
systems that contributes to performance. The three primary factors that
contribute to bicycling performance are: 1. strength, 2. power and
3. endurance. The strength component determines your ability to exert
large forces on your pedals for periods of time ranging from five
to 15 seconds. The power component reflects your ability to sustain
high levels of super-maximal effort for 60 to 90 seconds, and the endurance
component determines your ability to sustain moderate levels of power
output for the minutes to hours typical of road racing or touring
efforts. Each of these components represents a distinct performance
system, with distinct energy production mechanisms, and each will
respond to different, specific types of training overloads.
Most cyclists are aware
of an obvious example of how physical strength can affect their results:
namely, in the sprint efforts that conclude most cycling events.
Physical strength will affect your cycling performance in other,
less obvious ways as well. For example, the surges in effort that
are so much a part of cycling - those required to prevent gaps from forming
in a paceline or to get back on when you reach the end of a paceline,
or those needed to bridge small gaps between groups or to 'jump'
over those noxious little hills that dot the countryside - all require
strength. In fact, your ability to produce any intense, short burst
of effort will be affected by your physical strength. And, as mentioned above,
your strength performance is determined by an energy production system
that is totally, distinct from your endurance performance
energy system.
I noticed very early in my racing
career that many 'strong’ riders who seemed able to grind my legs
slowly to stumps during training rides, simply could not tolerate the
rapid changes in speed so typical of bicycle racing.
Competitive cycling is unique
for an endurance sport because it is not just a steady, smooth continuous
effort. Instead, it consists of periods of low-intensity efforts,
separated by periods of extremely high-intensity efforts, all jumbled together
in a seemingly random fashion. This places a premium on strength
performance factors not normally associated with endurance. Cycling
is also unique in that participants tend to travel in ‘packs,' which
offer so much protection to their members that it requires an almost
superhuman effort for individuals or smaller groups to break away. Again,
such super-maximal explosive efforts rely on a special energy production
system that is intimately tied to your muscular strength.
Unfortunately, training for
optimal physical strength requires that you overload your energy
production and musculoskeletal systems in a manner that is specific to the
physiological requirements of your strength system - i.e., high-intensity,
short-duration efforts. This is best accomplished by working against
controlled resistance devices such as weight machines or free weights.
The good news is that training
for improved strength involves such high-intensity efforts that it
actually requires less time than endurance training. In fact, my
three-day-a-week strength program takes only 75 minutes per session, including
a shower!
Personally, my biggest problem
with strength training is that I don't really enjoy the weight-lifting
'experience.' Yet it is a fact that certain limitations in cycling
performance can best be overcome by leaving the roads that you enjoy so
much and spending a few hours a week in the weight room.
In the periodized, seasonal
approach to optimal training, the initial training period, or season,
is devoted to developing a foundation of strength. Therefore, the strength
period should begin the formal training process each year for the
cyclist, and it should last from two to three months, depending upon
your stage of development, geographic location and general interest.
During this period you should continue to ride your bike in order
to maintain your aerobic base, but you should devote most of your hard physical
training efforts to resistance training.
Training during the
strength period
Fortunately, it is possible
to develop the desirable strength foundation with a remarkably simple
program of weight training using either weight machines or free weights.
My personal recommendation is to use machines rather than free weights
because the machines are safer, do not require spotters, provide
simple mechanisms for rapid setting of resistance, and are just as
effective as free weights for inducing strength gains.
An optimal resistance training
program should allow you to progress at or near your physiological
maximal limits while keeping your risk of injury to a minimum. Unfortunately,
any type of training that pushes you to the edge of your capacity has
inherent risks. You can minimize these risks but you must never forget
that they are ever present. I recommend a program of progressive
overload with regular periods of lesser intensity. This involves
combining periods of low-to-moderate-intensity high-repetition training
(known as hypertrophy periods) with periods of high–to–extremely
high–intensity low–repetition training (known as strength periods).
The process of combining periods
of hypertrophy and strength is consistent with the periodized training
approach. Since the strength period represents a smaller period, or
cycle, within the annual training cycle, the smaller cycles of hypetrophy
and strength within it are known as micro-cycles. This phased loading
and unloading will give your body the opportunity to recover from
your training effort, thereby minimizing the risk of injury.
While I use a specific 12-week
program, you can easily replace it with a program of your
own. Included are standard weight-lifting exercises which can be demonstrated
by the instructors at your local fitness center. The one-footed toe-stand
exercise is to be performed with only your body weight during the
hypertrophy phases, and with additional weight equal to your body
weight during the basic strength phases.
Note that the hypertrophy phase
is composed of weight-lifting sessions that require approximately
15 repetitions, while the basic strength phase uses approximately six
repetitions. During each phase, the resistance should be adjusted so
that the last lift (six or 15) is exhaustive, i.e., you could
not lift another.
