Problem
#1: Poor Hip Extension
Development
In
the past months I have had the opportunity to
visit some high schools across the Midwestern
United States. They invited me out on consultation
to assess their programs with relation to speed
development and give them some tips as far as
program design. Most schools have variations
on the same pieces of equipment and wear their
T-shirts with slogans like “450 lb Squat”
or “1500 lb Club” and other variations
on the theme. Others take pride in the depth
of their squats or their Tuesday/Thursday plyometric
program. Despite the programs that people are
using, I seem to find the same four problems
at every high school.
The
first problem is the lack of hip extension.
Hip extension is the pushing off portion of
a sprint gait or the extension of the lower
limb to the rear. Its purpose is to propel the
runner forward. Some indications that your athletes
lack hip extension is when you see a runner
bouncing up and down when they sprint, it is
a sign that there is poor hamstring strength
("Bouncing" Video). It shows that
the runner is using his quads to push his body
to propel himself forward in a vertical manner
instead of using his hamstrings to pull his
body down the track in a linear fashion ("Pull"
Video).

Another
indication of poor hip extension is watching
a runner start. The runner will have no propulsion
out of the blocks. Their feet will almost be
on the ground at the same time, or pretty close.
The distance covered will be small ("Bad
Start" Video). In fact, they will almost
shuffle out of the blocks. Listen, because you
can hear the difference. The same holds true
when they are sprinting. Their stride will be
short and sometimes even have a shuffle ("Shuffle"
Video). These circumstances are very similar
to what can be seen as a push runner. While
a push runner may have some hip extension weakness,
this group prefers to use their quads as the
main source of propulsion. They will be slightly
bent forward and it literally looks like they
are pushing themselves down the track and they
may cover some ground due to the strength that
they have built up in the quad area.

Here
is a comparison between the two types of runners
side by side. The athlete in the yellow seems
to be pushing down the track, hunched over to
allow the push to occur. There does not seem
to be much of any extension from the hips. The
athlete in white has more extension. Notice
the extension in back and the increased distance
covered. Both athletes are over 6’ and
220 with similar numbers in the weight room.
The athlete in white is .2 faster in the 40
yd dash ("Comparison" Video).
So why do athletes seem to lack hip extension?
The simple conclusion is that they don’t
train to develop hip extension. When you walk
into most weight rooms, what do you see? Some
squat racks, a leg press of some sort, a leg
extension and a leg curl. It is an Arthur Jones/Joe
Weider/ Hammer Strength dream come true. Do
any of these pieces develop hip extension? No.
Do we tell our athletes that these are the things
that will make us fast so we’ll do them
on every leg day? Do we tell our athletes this
because that has been the way that everyone
else has done it, and in the back of our minds
we think fast athletes are born and not made?
The leg press does not help our cause. In fact,
it locks our hips so there can be no hip extension.
Squats are a little better but there is no propulsion
to the rear and we are teaching our body to
decelerate when we need it to be accelerating.
Leg extension and leg curl are not helping at
all. Once again our hips are in a fixed position
and we are moving around the knee joint. In
fact, a good road to ruin is the leg extension.
Everyone thinks it helps you knees but it is
really wearing them down. But this is a different
subject. The power clean seems to be the answer
for the gym rats. Watch most high school athletes
perform any Olympic movement. There is minimal
hip action because too much emphasis is on the
amount of weight used and everything becomes
a complicated shrug/reverse curl. Additionally,
the speed of the hips during the lift is incredibly
slow in comparison to the extension in a sprint
and again, there is no true extension. If there
was, you would end up on your back with the
weight across your neck.There is hope however.
There are many exercises that develop hip extension.
In the weight room, an athlete can do ISO or
RA/REA Glute-Ham raises or Reverse Hypers, preferably
with a toe pad and not a strap, strictly for
Reactive purposes (it will smash your shins
or fingers, I think I have a permanent bump
on my finger). The ISO Glute–ham can be
used on any lat pulldown machine or a seated
calf raise. Put your ankles where your knees
go and extend your body and hold. For the reactive
style, you need to use a glute-ham machine("REA
Glute-Ham" Video).

ISO
Reverse Hypers can be done anywhere by holding
your lower body off an edge of a bench and putting
weight between your ankles. The reactive types
need a Reverse hyper machine. Also, reactive
split squats can help ("RA Split-Squat"
Video). Make sure that you have mastered the
drop before going on to the reactive movement
("ADA Split-Squat" Video). Another
great exercise is the 4-way hip machine. On
the track, stiff leg sprints or prime times
are great ("Prime Times" Video). So
are any other types of bounds both from a fly
start and from a stance. RA Split squats in
any form also seem to work well. All of these
would be a good start.
