Injuries often plague the life of a runner. When they happen, they are
painful, debilitating and frustrating. The most frustrating part of
being injured is knowing that your hard-earned
fitness
is deteriorating while you take time off from
training
to heal.
In fact, this frustration can be so great that runners are often too
reluctant to take time off or tempted into resuming training too soon.
Consequently, injuries become worse or last longer than they should.
One way to prevent this sort of self-sabotage is to choose a favorite
go-to cross-training activity that you can switch to whenever an injury
makes running impossible or unwise. Having such a fallback option
greatly reduces the temptation to run when you should not because it
enables you to preserve fitness even when you cannot run. Obviously,
there is no alternative to running that builds and maintains
running-specific fitness as well as running itself, but there are some
alternatives that come relatively close.
The best running alternatives are those that are most similar to running
itself. Activities such as swimming and rowing are not great
alternatives to running because, while they stimulate the cardiovascular
system, they are arm-dominant versus leg-dominant movements. So what are
the best activities for "training through" running injuries? Here are my
top five:
Antigravity Treadmill Running
The
Alter-G antigravity treadmill
is, in my opinion, the single most important running-related invention
in history. It is a normal treadmill with a tent-like enclosure attached
to it. The user steps through a hole at the top of the enclosure and
seals himself in around the waist, creating an airtight seal. The
chamber is then pressurized, and this high-pressure zone effectively
reduces the force of gravity within it. The amount of pressure is
adjustable, enabling the user to run at anywhere between 20 percent and
100 percent of his actual body weight.
I have had every type of running overuse injury that exists, and I have
used the Alter-G treadmill several times. Based on this experience I can
say that runners can train through any injury--pain free and without
setting back the healing process--on this machine. What's more, it is
not an alternative to running; it is running. Therefore it is superior
to every form of cross-training in terms of building and maintaining
running fitness.
Case in point: The formerly often-injured runner Dathan Ritzenhein
trained exclusively on an Alter-G for several weeks while nursing an IT
band injury. He was only ready to return to regular outdoor running two
weeks before the 2008 USA Cross-Country Championships. Nevertheless, he
won the race easily. That simply would not have been possible had he
been forced to resort to pool running or bicycling.
The downside of the Alter-G antigravity treadmill is that it costs
$75,000. Only a handful of units are accessible for injured runners to
use in high-end physical therapy facilities. It will be a while before
antigravity treadmill running is a realistic option for most runners.
Steep Uphill Walking
In my opinion, the next best thing to running on an antigravity
treadmill is steep uphill treadmill walking. Research has shown that the
human brain uses exactly the same motor pattern to run or walk briskly
on steep gradients. In other words, when you crank the treadmill incline
up to 12 to 15 percent, running becomes walking and walking becomes
running. Therefore, walking on a steep incline is a highly specific way
to maintain running fitness. But impact forces are reduced drastically
compared to running, so steep uphill walking is possible with most
injuries.
Many runners don't think of walking as a good alternative to running
when injured because they assume they cannot match their normal
intensity. Trust me: You can. Set the incline at 12 to 15 percent,
increase the belt speed to 4 mph or so, check your heart rate and you'll
see.
The only limitation of steep uphill running is that, while it is a
low-impact activity, it is not a non-impact activity. Thus it cannot be
done pain-free with all injuries. For example, I was unable to use steep
uphill walking as an alternative to running once when I had an Achilles
tendon strain.
Pool Running
Pool running is the traditional alternative to normal running. There are
two types of pool running: deep-water running, where the feet do not
make contact with the bottom of the pool, and shallow-water running
(usually waist high), where the feet do make contact with the bottom of
the pool. I think that shallow-water running is preferable because it
enables the runner to better maintain adaptations to repetitive impact,
thus reducing the risk that new injuries occur after the runner returns
to normal outdoor running.
As with steep uphill walking, though, because shallow pool running is a
low-impact (versus a non-impact) activity, it cannot be done pain-free
with all injuries.
Elliptical Training
The elliptical trainer was specifically designed to mimic the running
action without impact, and thus it offers an effective way to maintain
running fitness. I find it incredibly boring, though, so I only do it
when I'm really desperate.
Cycling
Cycling may seem less running specific than the other running
alternatives discussed in this article, but a lot of noteworthy runners
have used it with great success. For example, in 2004, Meb Keflezighi
relied heavily on bike training to build fitness for the New York City
Marathon because of injury troubles. He still managed to finish second.
