As runners, we all consistently
take strides to improve our time on the road. We aim
for a faster pace, a farther distance, or even just
the ability to end a long run feeling like a graceful
gazelle instead of a crawling gopher. That’s likely
why the proper running technique and how to achieve
the perfect take-off and landing remains a hot topic.
But should you even focus on your form, switching up
how you naturally transfer weight from one step to the
next? Will a tweak in your technique get you to the
finish line faster, or could it sideline you with an
injury?
The truth is, that’s
a really tricky question. While you’ve probably
heard some tips on proper running form—stand tall
with a slight forward lean, arms gliding back and forth
as you land softly on your forefoot and take off solid
hip extension behind you—everyone’s mechanics
vary. So while a few small tricks might be the start
of feeling stronger as you stride, there’s a fine
line between changing too much, which can lead to new
injuries, and finding a few fixes that help you run
more powerfully, sans pain. Let’s examine the
step-by-step distinction.
How
Your Stride Can Lead to Injury (or Not)
On a run, you experience a reactional force every time
your foot hits the ground, says Bryan Heiderscheit,
P.T., Ph.D., physical therapist and director of the
University of Wisconsin Runners Clinic. That force can
look different from person to person, depending on performance
and mechanics. “When you hit the ground, the body
absorbs energy from that force. For instance, your knee
bends to help cushion the landing and decelerate the
body’s center of mass,” Heiderscheit explains.
“In some individuals, you start to see motions
that aren’t so helpful to running—the body’s
secondary way to absorb energy.” For some, this
might include hips dropping to the side, or the trunk
leaning side to side, or the knee collapsing inward.
Heiderscheit says we’ve
oversimplified what this force reaction looks like in
some individuals. People might point out that the impact
of a heel striker is much greater than that of a midfoot
or forefoot striker. In actuality, it’s just different
forces acting on the body, not necessarily greater ones.
“If you’re landing on your heel, you’ve
lost a lot of ability in the ankle joint to absorb shock,
while the ankle is more involved in midfoot or forefoot
landing,” Heidersheit says. “That can be
a good thing, as another joint absorbs impact, so your
knee or hip don’t have to do as much. But it could
also be a negative in that if you’re not ready
for the ankle to absorb the shock, then the calf muscle
and tissues around the ankle get exposed to bigger loads
than what they’re ready to take on.” So
simply making the switch from heel to forefoot strike
doesn’t mean you’ll redistribute the impact.
Rather, the adjustment could lead to other problems.
The same thinking applies to pronation. Researchers
still debate whether pronation even leads to increased
injury risk: One study that looked particularly at shoes
helping to control pronation says, yes, those who pronate
and run in a shoe that doesn’t control it could
have a higher chance of injury. Another says moderate
pronation does not increase injury risk, even if wearing
a neutral shoe.
“The challenge is
that we don’t know when pronation gets to be too
much, and pronation may be a fairly minor component
to injury risk,” says Heiderscheit. “I think
over the years, it’s gotten its own reputation
that we need to think about a lot, and I think that
has happened in the absence of science.”
When
You Should and Shouldn’t Change Your Stride
The minimalist footwear movement certainly had its moment
in the past, and it focused on letting your feet run
free—no extra cushioning or stable outsoles to
keep your toes or heels from moving on their natural
path. While it sounds like solid practice in theory,
problems arose because most runners didn’t prep
their bodies for the change in mechanics that kick in
when you swap your cushioned shoes for a more minimal
design.
A lot of shoes have a cushioned
heel for more protection as you land, especially for
those who heel strike. Take that away, and it can lead
to more knee or hip problems. Or switch to a midfoot
strike to accommodate the shoe, and you might experience
more ankle or calf injuries. “However, as long
as people make changes slowly, your body is usually
able to adapt to some small modifications in footwear
or running gait,” says Brett Toresdahl, M.D.,
assistant attending physician at the Hospital for Special
Surgery and research director for the HSS Primary Care
Sports Medicine Service. “But the bigger changes
bring on injuries.”
Likewise, you don’t
want to focus on too many changes at one time. “If
we see someone and they have a lot of things going on—a
lot of instability, a lot of running faults—we
wouldn’t take an aggressive approach, changing
a lot of things in their mechanics at once,” says
Rondel King, exercise physiologist at New York University’s
Sports Performance Center. “If you toss a lot
of drills and mechanics at someone, it’s exhausting
both mentally and physically. So what drills would be
best suited for them as of right now?” Rondel
says they choose one or two to focus on, have the runner
practice it, then check out what’s happening a
few weeks later when they’ve had time to adjust.
What is Mindful Running and How Do You Do It?
While some major changes to a stride (say, changing
the foot strike) take some practice and careful viewing,
you can easily implement other run cues into your training
with little risk of injury, says Colleen Brough, D.P.T.,
assistant professor of Rehabilitation and Regenerative
medicine at Columbia University and director of the
Columbia RunLab. Most of these cues require applying
your mind to your movement. For example, think about
a slight forward lean at the ankles (not a hunched position)
to help the glute engage, or literally squeeze the glute
on your push-off or engage the core more to keep you
stable and upright.
“You don’t
have to (and shouldn’t) apply these cues throughout
the entire run—try it for maybe 30 seconds at
the start or the middle and then on the hills or when
you tend to get tired,” says Brough. “Eventually
it becomes natural, and you’re better able to
engage glute or core muscles.”
If you tend to bounce up
and down a lot, which leads to more stress on the joints,
Brough suggests another cue: Keep an eye on something
in the distance in your line of sight. If you notice
it moving up and down a lot, then you need to eliminate
some of your vertical bounce. Similarly, paying attention
to the noise you make when you land (if you hear a slap
slap slap with each footfall) should help you notice
whether you need to engage the core more or lean forward
slightly to soften the landing.
“The best way to
know if [these cues and changes] help is if they alleviate
pain on the run. For example, at mile 10 or 15, if you
start getting knee pain, and you use the glute push-off
cue and the pain goes away,” says Brough. “It
also informs you, as the runner, where the likely issue
is, and then maybe that’s where you want to start
strengthening.” (Keep in mind, all experts mentioned
that strengthening your glutes or core alone doesn’t
mean they’ll automatically lighten up on the road.
You have to think about using them for proper activation—and
those are welcome changes to your run form.)
Should We Really Care About Cadence?
Because keeping your feet underneath your body is also
super important to lowering the impact on your joints,
Heiderscheit suggests examining your step rate or cadence,
another accepted switch in your run mechanics. The exact
number varies person to person, but to figure out yours,
count the number of steps you take per minute, then
increase it by 2 to 5 percent and see how that feels.
Brough does suggest taking
a video of yourself running. Analyze what your form
looks like compared to someone who makes running 26.2
look like a walk in the park. Maybe you notice a high
bounce or that your feet step way out in front of your
body. Those few earlier cues just might help fix the
problem and make your run more efficient. “If
you have to look really hard, though, then there’s
probably nothing there,” Brough says.
How
Shoes Affect Your Stride
There are plenty of ads that say a shoe will change
your run game. And it could be partially true—you
need a comfy pair to get you through mile after mile.
But if the shoes don’t feel good, then they won’t
protect you from injuries or get you to a finish line
faster.
“When it comes to
choosing a running shoe—a minimalist or stability
shoe—research shows the folks with the least injuries
are simply the ones in the most comfortable shoes,”
Brough says. “So I’m not going to change
the amount of someone’s pronation, but I am going
to encourage them to try on different sneakers and find
the most comfortable, because that will likely be the
best footwear for them.” If you do pronate but
a stability shoe just doesn’t feel good, then
it’s probably a no-go for you.
There is also the case
for a shoe that makes you feel like you’re running
stronger, says Brough. Between feeling comfortable and
feeling strong, perception is half the battle when it
comes to the right shoe for you.
Heiderscheit mentions that
if you do switch shoes and feel pain after a run, it’s
time to examine the shoe. Switch back to your old pair
to see if the problem pops up again. If not, then it’s
probably best to forego the new pair. If yes, then it’s
time to examine your mechanics.
The
Bottom Line
Whether you adjust your stride or not comes down to
your goals and how you feel on the road. If you’re
feeling fine, crossing off mega mileage without injury,
there’s no reason to start switching things up.
(If your stride is not broken, there really is no reason
to fix it.)
“I believe that there
is no perfect running form; each runner has a signature
form,” Brough says. “We can choose to optimize
that form to either enhance performance or attempt to
prevent injury. But there’s nothing out there
in running medical literature that says that if you
have this form, you’re definitely going to get
injured.” Brough uses one
of her clients as an example—a four-time Olympic
trails qualifier who happened to have the worst running
mechanics she’s ever seen. “There was no
way I was going to change that,” she says. And
while that person ran injury-free, another person she
might see with the same form could end up with a slew
of issues.
Heiderscheit agrees that
fixing form just to experiment could lead to more bad
reactions than good. “When we do gait recommendations,
it’s on people experiencing injury or chronic
symptoms. Gait re-training can be beneficial for those
who experience a lot of pain in the same area or for
several months or years, or even who get reoccurring
stress fractures,” he says. “But I don’t
recommend people adjust gait in the absence of injury.
Occasionally performance might be a reason, for instance,
if mechanics aren’t efficient, and a runner experiences
a high energy cost, he or she might benefit from changing
gait. But changing gait to prevent injury—that’s
a very slippery slope.”
“Nobody fits that
idea of the perfect running form. I think people get
hung up on the subtle variations or deviations that
aren’t really deviations,” Heiderscheit
adds. “Variability is completely fine, and that’s
normal and healthy. I usually try not to let people
focus on the subtlety. But if you’re having pain,
that’s what changes the game.”
