In mountain biking, wasted energy is akin to wasted money. Nobody
would stand around throwing away hundred dollar bills, but many of us
waste precious energy with each pedal stroke without a second thought.
Energy is a limited resource, and the first thing on our minds should
be riding as efficiently as possible.
Fortunately, efficiency is
something that can be learned. With practice and patience, you can
learn to stretch your energy dollar.
WHERE TO START
The best place to start is with the pedal stroke. When we first learn
how to ride, the mistake we all make is pedaling in squares, or
"mashing." This means pushing downward, while neglecting the upward
pull. But if you train yourself to pull upward, the dead spot in the
pedal stroke is eliminated and less energy is wasted in the downward
stroke.
Spinning is the core of proper technique. Mastering this skill can
make a good cyclist into a great cyclist. Spinning is a pushing and
pulling of the pedals simultaneously. As one foot is pushing downward,
the opposite foot is pulling. Sound easy? It isn't. The difficulty lies
in the contracting and relaxing of the muscle in the upper leg. This is
where the practice portion comes in. At first, this takes a lot of
concentration, but as you become more comfortable, it will become
almost effortless. The key is to learn how to focus on the upward
motion of the pedal. Clipless pedals, as opposed to toe clips, will
make the process easier. (Note: this training procedure is impossible
to perform without clipless pedals or toe clips.)
HARD EARNED ADVICE
Don't be afraid of clipless pedals. It will usually take the average
person about two rides to become accustomed to their mechanism. If you
ask anybody who uses them, they will tell you that they can't ride
without them.
Another useful tool for increasing pedaling efficiency is a cadence
meter. The purpose of the cadence meter is to inform the rider at what
RPM he is pedaling. This is where the importance of leg speed comes in.
Leg speed is defined as the rate at which the rider is turning the
pedals over. The higher the revolutions per minute, the higher the leg
speed. By training leg speed, the rider is training the body to call
upon muscle fibers for a desired amount of time. Spinning at a high rpm
for a long distance helps the rider increase neuromuscular memory.
In the beginning, this type of training is best performed on a smooth
surface. This doesn't mean you have to give up your dirt ride. Just
pedal to the trailhead instead of driving there. If you don't live
close enough to a trailhead, park your car a few miles away from where
you start. Start off in an easy gear and work on staying in the 90 to
100 rpm range. This is going to feel somewhat strange at first. You are
pedaling very fast, but you are not rolling at a very high rate. Don't
let this anxiety force you to shift to a higher gear and ruin your
cadence. Remember, you are practicing to become fluid. Concentrate on
pushing and pulling and the timing of the muscle contractions of your
upper leg. As you are doing this, be aware of what the rest of your
body is doing. Start from your head and move all the way down to your
toes. You are looking for any place where your body is wasting energy.
Relax any muscles that are not directly involved in the pedal stroke.
Keep your head up and your posture stable. Don't slouch your shoulders
or spine. Keep your arms slightly bent, so that you can absorb shock
with your arms and not your back. Relax your grip. Don't let your hands
clench the bars. Believe it or not, you can even use up a lot of energy
squinting your eyes.
THE LEARNING CURVE
After two to three weeks, you will begin to notice that your climbing
is smoother and more refined. This is a manifestation of learning to
pull the pedals. You will notice that you become quite smooth in rocky
and technical climbing sections. Your endurance will go up, your speed
will increase and your drive train will last longer. Above all, you
will be much more fluid on the bike.
MASTERING THE ART
After you have mastered the art of the spin, it is time to work on
long climbs. The goal of climbing is to be comfortable in the saddle
while spinning for long periods of time. This is where you develop a
lot of your strength and power. Power is a term given to the ability to
exert maximal force during a specified effort. Remember, don't rush
ahead. This type of training is to be done only after a smooth spin and
leg speed have been developed. This is to prevent any problem that can
be caused by excessive mashing. Without the proper form, many
experience pain in the lower back, premature fatigue in the quadriceps
or pain in the knees from excessive sheering force due to
underdeveloped musculature. Many of these problems can be remedied by
working out in the gym to increase strength in the upper body and legs.
An area that should be emphasized is the trunk, which includes the abs,
obliques and erector muscles of the spine. This is the hub of your body.
Even if you aren't a racer, don't neglect your technique. Better
technique is not just about winning races, it is about having more fun.
Don't turn this into a job or work. Just take the time to observe your
techniques and evaluate where you should improve. Proper technique will
ensure less injury and a much more enjoyable experience each time you
go out.
