Why should we consider
Evolution in Running?
WALK, RUN AND SPRINT HAVE
BEEN OUR NATURAL
LOCOMOTION FORM SINCE 2M
NATURE HAS LITERALLY
ENGINEERED US TO RUN
WE EVOLVED AS
ENDURANCE RUNNERS
10.
WHY 80% OF US GET
INJURED?
WE HAVE THE BEST HI-TECH SURFACES
WE HAVE THE BEST RUNNING SHOES
WE HAVE THE BEST COMPRESS SHOCKS
WE HAVE THE BEST CONTROL ORTHOTICS
WE HAVE THE BEST RUNNING FORM ANALYSERS
WE HAVE THE BEST COACHES, PHYSIOS AND DRS
…EVER…
18.
Running in Evolution
We run since 2.000.000
years…
We shoe or feet since
40.000 years…
We cushione our shoes
since 35 years…
…What´s new/What´s
old?

A Brief History of Running
For millions of
years, humans have
gone without shoe
running very long
distances for
hunting pursuing
them to death!
20.
Endurance Running Hypothesis
The hypothesis suggests that
endurance running
played an important role for early
homínids in obteining
food.
Researchers have proposed that
endurance running
began as an adaptation for
scavenging and later for
persistence hunting
21.
The clue:
To be economic…to get NOT injured
Cells´ aim is being economic
All natural procedure last forever if the are
economic and safe
22.
Running Vs Walking
There are structures that improve running only , and
are not used in walking.
Running was an
Adaptation for surviving , not
became as a
byproduct of walking.
23.
THE ONLY HUMAN NATURAL
LOCOMOTION FORM ARE:
WALKING
RUNNING
SPRINTING
RECENTLY WE DEVELOPED
JOGGING…
WHY?
24.
So…
What can 35 years of f***ing
shoes & fitness industry may
do against 2M years of
evolution?

Strike frequency
Stride frequency measured the number of foot contacts
per minute
Highest frecuency=
Encoureges Knee Bent Posture at Initial Contact
Decreases Stance Time
Closers Foot Contact to COM
Shortens lenght
31.
Stride length
Stride length was defined as the distance from the
point of touchdown of one foot to the point of
touchdown of the opposite foot
32.
Ground Contact Time
GCT = duration from touchdown to toe-off (150-220ms)
The short GCT is related to good running
economy since there is less time for the braking
force to decelerate forward motion

East between Damascus and Moscow from the
centuries, are credited for the introduction of the

stirrup plate.
From the time of the Greeks, Count Fulk of Anjou
introduced long pointed toes to cover up some
deformity of his feet, and courtiers quickly adopted.
But in the French court of Louis XIV, the rugged
Mongolian heel underwent a radical cosmetic
transformation eventually leading to the ultimate
idiotic expression of modern fashion - the stiletto heel
adopted the fashion

Chronology of the running shoe.
• In 1830 by the Liverpool rubber company owned by
John Boyd Dunlop, , called as sand shoes because
they were worn on the beach by the Victorian middle
classes
• In 1933, Dunlop launched its Green Flash range of
trainers.
• In 1920 Adi Dassler (and his brother Rudolf) started
making sports shoes in Herzogenaurach, Germany
• In 1948 ADIDAS (Adi Dassler) was formed with the
now famous three stripes logo developing from three
support leather bands used to bolster the sides.
44.
…
• In 1956 Rudolf Dassler broke away to form PUMA.
• In 1971,Americans Phil Knight, and his coach Bill
Bowerman founded NIKE.
• In 1977 ASICS first introduced its shoes in North
America
• In 1979 REEBOCK (species of an African gazelle)
entered the US Market
• In 1987 was declared the Year of the Running. Also
NIKE launched it's flagship running-shoe, the Air
Max.

Why are super shock-absorbing athletic
shoes causing more running injuries?
Why do
modern
running
shoes screw
it up?
Dr. Steven Robbins
The lower extremity
is a rugged, flexible,
active, well designed
structure wired to a
spinal cord and a
b r a i n a n d f u l l y
capable of handling

Blocks awareness sense
53.
The ankle, knee and hip joints flex to absorb impact in
response to “information” flowing in from the foot.
54.
Arch Support or orthotics, support midfoot arch fighting to
the flattering and leading to atrophy of the intrinsics
muscle with complete loss or active muscular control
55.

Hamill and Bates,1988.

60.
Perceptual Illusion
Robbins and Gouw,1991
It might be more appropiate to clasify
athletic footwear as “safety hazard”
rather than “protective devices”
61.
Deceptive Message
Robbins and Waked (1997)
Running injury rates are greatest
in users of the most expensive
shoes
62.
Conclusion
Shoes are the primary cause of running injuries is strongly supported
by the scientific literature
Young children should be encouraged to spend as much time as
possible barefoot. We know that this is especially important for the
proper formation of the foot arch in the first six years of life.
Runners should consider incorporating sessions of barefoot running
into their training.
"Running barefoot a couple of times per week can decrease your risk of
injury and boost your 'push-off' power."
Your feet will need to toughen-up so start with small doses
Runners may want to consider switching to a lightweight shoe that
provides less cushioning and no arch support
64.
The reality is…
80% of runners suffer from injuries yearly...
80% of runners heelstrike...
65.
Overuse often compounded by an underlying mechanical
abnormality such as overpronation or flatfeet.
The traditional answer is…
66.
Modification of training
Physiotherapy
Stretching
Close look at the runner's footwear with
recommendations about motion control, stability,
cushioning
Orthotics
The classic treatment is…
Why are two of every three
runners sidelined every
year because of a
running injury?
67.
Not the only guilty…
The modern running shoe itself may be the major cause
of running injuries

Foot strike patterns and collision forces in
habitually barefoot versus shod runners
Daniel E. Lieberman
Nature 463, 531-535 (28 January 2010)
Humans have engaged in endurance running for millions of years1,
but the modern running shoe was not invented until the 1970s. For
most of human evolutionary history, runners were either barefoot
or wore minimal footwear such as sandals or moccasins with
smaller heels and little cushioning relative to modern running
shoes. We wondered how runners coped with the impact caused by
the foot colliding with the ground before the invention of the
modern shoe. Here we show that habitually barefoot endurance
runners often land on the fore-foot (fore-foot strike) before bringing
down the heel, but they sometimes land with a flat foot (mid-foot
strike) or, less often, on the heel (rear-foot strike). In contrast,
habitually shod runners mostly rear-foot strike, facilitated by the
elevated and cushioned heel of the modern running shoe.
Kinematic and kinetic analyses show that even on hard surfaces,
barefoot runners who fore-foot strike generate smaller collision
forces than shod rear-foot strikers. This difference results primarily
from a more plantarflexed foot at landing and more ankle
compliance during impact, decreasing the effective mass of the
body that collides with the ground. Fore-foot- and mid-foot-strike
gaits were probably more common when humans ran barefoot or in
minimal shoes, and may protect the feet and lower limbs from
some of the impact-related injuries now experienced by a high
percentage of runners.

4. Pronation is unnatural.
Pronation is the natural, inward roll of the
foot.
Pronation is good, while absorbs some of
the impact when you run.
Barefoot Running Myths
97.
5. No Elite runners run barefoot.
Running companies sponsor a tremendous

He did this in his bare feet.
An isolated native tribe in Mexico known to the rest of the
world as the Tarahumara run ultra-marathon races lasting
up to 200 miles or more and do so in bare feet or
minimalistic sandals called huaraches.

ABOUT POSE METHOD® OF RUNNING?
Pose Method® of Running technique, aka POSE
Running, is a better way to run.
Developed in Soviet Union in the 70’s, Pose Running
was published in America in the 90's and is now
taught and practiced all over the world.
It is used by athletes of all levels and non-athletes of
all ages
POSE METHOD
by Dr. Romanov
108.
There are 20 studies and scientific
papers, studies and scientific paper including
5 dissertations on Pose Method® published to
date in Russia, South Africa, Great Britain, New
Zealand and United States.
POSE METHOD
by Dr. Romanov
109.
1. S-like body position with slightly bent knees
2. Forward lean from the ankles to employ
gravity and work with it not against it
3. Pulling or lifting feet up under the hip not
behind the buttocks
4. Ball of foot landing under your body (your
GCM - general center of mass)
POSE METHOD

In 2008, several major Health Insurance
Companies in the European Union, accepted
Pose Running Clinics as “a preventative
measure according to German health
legislation”.

Conclusions
Pose running in comparision with either midfoot or
heel-toe running was associated with :
• shorter stride lengths
• smaller vertical oscillations of the sacrum and left
heel markers
• neutral ankle joint at initial contact,
• lower excentric work and power absorption at
the knee.
119.
The biomechanical variables associated with
specific running styles change with:
-running speed.
-inclination of the running surface.
-the use of running shoes.
-the use of treadmills.
Conclusions
120.
Conclusions
Sustaining the horizontal velocity of the centre
of mass (CoM) is the biomechanical goal of
running and represents the summation of body
and limb motions.
Less reduction in horizontal velocity of the
CoM during the braking phase should be
beneficial to a runner
121.
Dallam et al. [4] found in the Pose® group a significant increase in stride
rate and reduction in vertical oscillation of the CoM in comparison to the heel-toe
group at a given treadmill speed following the Pose® method intervention.
Pose® runners in the barefoot condition had
less horizontal braking and propulsive GRF
than when heel-toe running.
122.
Running Style
Running style may be described by the overall
action, body angle, arm swing, foot placement,
rear leg lift, and length of stride.

Sustaining the horizontal velocity of the
centre of mass (CoM) is the
biomechanical goal of running and
represents the summation of body and limb motions.
Less reduction in horizontal
velocity of the CoM during
the braking phase
should be beneficial to a
runner.
Range of motion
of the lower
limb(knee flexion and
extension), affect
stride length and
stride frequency.
126.
.
Avariety of angles for knee
flexion have been found for
support, ranging from 38 to 50°
for speeds of 3.4 m/s to 7.5 m/s.
At terminal
stance, the knee does
not fully extend
127.
Knee extension also correlates with vertical oscillation
of the CoM
Lower vertical oscillation of the CoM is a trend
found in faster runners.
128.
Running economy is often proposed to be a
primary determinant of competitive
endurance running success
54% of the variation in running economy
attributed to biomechanical variables.
129.
“A simple force
diagram will reveal
that the further
ahead of the
body the foot
strikes the
ground, the more
acute the angle
and the greater
the
deceleration
from ground
resistance”
Slocum and Bowerman highlight the cause of deceleration
of the CoM during the braking phase:
130.
Running/Walking Barefoot is
Healthy
Spending time in your own feet strengthens the
muscles is your feet and aligns your spine, which in turn
helps maintain good posture and balance.
Running barefoot reduces the amount of impact
stress that your lower body endures, minimizing the
potential for injury normally associated with running.
132.
Unnatural Stride
The resulting shoes cause
most runners to run with an
unnatural heel-to-to stride
If you tried to run this way in
bare feet, the pain would be
extraordinary: the shoes
block the pain, but
they do not stop the
impact.
133.
The Natural Stride
Running Barefoot forces
runners to stay on the balls
of their feet.
The heels are almost
entirely eliminated during
running.
This stride significantly
reduces impact and
increases running
efficiency.
134.
Footwear Alternatives
Running barefoot can be
dangerous in many modern
conditions.
Rocks, broken glass, sharp
rusty metal and many other
dangerous obstacles may
be encountered while
running barefoot.
Thankfully, there are
alternatives…
