Sprinting Form & Technique
Jim Bell, PhD
Many
of our IFPA Certified Youth Fitness Instructors, Certified Speed & Agility
Coaches, Tennis Conditioning Specialists and other Sports Conditioning
Specialists have requested additional information on the correct techniques for
sprinting. Since sprinting is the most essential and basic of all
athletic movements, I am pleased at the high level of interest and am happy to
supply detailed information on sprinting form and techniques.
Please keep in mind that while there is no perfect style for anyone or
any body type, proper sprinting form is not a natural act.
There are approximately 200 different details I look at when I train
someone to sprint. I will cover the
top 50 or so details in this article.
The
40-yard dash has become the single most important test used by professional and
college football coaches to evaluate potential players for positions,
scholarship offers, and pro contracts. Other
sport coaches are finding the 40-yard dash and its variations equally important.
Make no mistake on this – the success of a future in sports (football,
basketball, tennis or any sport that requires SPEED) depends on your athlete’s
time in as short a distance as 20-60 yards.
Teaching your athlete to sprint correctly can be the most crucial time
you will ever spend.
Our
first goal in sprinting is to strengthen core stability to enable your athlete
to use their kinetic chain as efficiently as possible.
The IFPA Tennis & Fitness Academy students spent two hours/day on
exercises to accomplish this goal. Strength
training is conducted every morning utilizing as much core training as possible.
The afternoon session focuses on speed, agility, power, balance,
coordination, and both aerobic and anaerobic conditioning to increase the
efficient use of the kinetic chain. One
philosophy of sprinting is that an athlete’s performance is based on how
efficiently the athlete can transfer ground forces through the kinetic chain
(foot - ground force generation - to - ankle - lower leg - knee - thigh - hip -
trunk - shoulders - arms).
-
Many
coaches look at the efficient use of the kinetic chain as the true source of all
athleticism. Therefore, to teach
correct sprinting, I start from the ground up.
Sprinting has four phases:
I
The Propulsion Phase
1. The toes of
both feet should point directly forward or slightly toe-in. Never toe-out!
Toe-out causes some of the propulsion energy to push the athlete laterally
instead of directly forward.
2. Extend
powerfully with the hip and thigh through the knee.
3. Extend
powerfully through plantar flexion on the ball of the foot (plantar flexion -
toes point). Many coaches teach pushing through the toes. There is little
power and no balance on the toes. Power comes from the ball!
4. Push
powerfully through the foot to project the body forward.
-
Requires
power and coordination between arm drive and leg drive.
-
Powerful
hip flexion – driving the thigh up and forward.
Both thighs must remain in the vertical plane. Watch carefully from the front and look for any lateral
movement in the driving thigh. Lateral
movement dissipates energy laterally instead of driving 100% forward.
The support leg as well as the entire body should always remain in
the vertical plane (correct any and all lateral movements).
The thigh should drive powerfully to a position parallel or near
parallel to the ground. If this
position cannot be achieved (ordinarily because of lack of flexibility or
strength) optimum stride length cannot be achieved.
-
Arm
drive is essential in this phase. Arm
drive and arm frequency control leg drive and stride frequency (the faster
the arms drive, the faster the legs move).
Arms move opposite the legs – as left leg drives forward, the right
arm is driving forward. It is
important to teach arm drive forward as well as backward.
(Remember the laws of physics: for
every action there is an equal and opposite reaction).
In order to drive the arm powerfully forward, your athlete must drive
the opposite arm powerfully backward.
-
Arms
should be bent at 90° throughout the sprint.
-
Arm
drives forward to a position where the hand is approximately even with nose
height.
-
Arm
drives backward to a position where the hand slightly passes the buttocks.
-
Avoid
tying-up. Tying-up occurs
when both agonist and antagonist muscles (opposing muscle groups) contract
forcefully at the same time. For
instance, the athlete is trying too hard and contracts the biceps brachii
(in the front of the arm) at the same time contracting the triceps brachii
(in the back of the arm). The
inability of the over stimulated athlete to successfully relax the
antagonistic muscle group results in inefficient arm drive and slower speed.
-
Tying-up
can be avoided by keeping the fingers of both hands relaxed and cupped.
Tell the athlete to keep his or her fingers lightly
together – visualize holding sheets of paper between each finger without
wrinkling the paper.
-
Coach
your athletes to understand that their ability to relax their muscles
quickly is just as important as their ability to contract their muscles
quickly.
-
Arms
should swing smoothly and effortlessly from the ball-and-socket joint of the
shoulder joint. Tying-up can
result in hard contractions of the latissimus dorsi and other muscles.
The lat spread can cause the elbows to spread laterally.
This creates a shoulder rock that will dissipate the energy of the
arm drive out to the side, instead of driving forward.
-
Shoulders
should be relaxed and down. If
you see the shoulder rise toward the ears, coach the athlete to relax or
drop the shoulders.
-
Eyes
are focused approximately 20 yards ahead.
-
Head
is held neutral in the vertical plane.
-
Jaw
is slack in order to prevent tying-up, therefore, aiding the athlete to
relax.
-
Keep
the ankle locked up (in dorsi flexion) until the landing phase.
-
Hips
and shoulders should be squarely facing forward in the direction of the
sprint.
-
Maintain
strong intra-abdominal pressure (suck the belly-button towards your
backbone). This is an essential
foundation of all athletic movement. Intra-abdominal
pressure creates a solid wall that the abdominal and trunk muscles can push
against. This enables the
muscles of the trunk to quickly and efficiently contract.
Great athletes know this instinctively – all others must be taught in
order to become Great Athletes! Without
intra-abdominal pressure, the muscles cannot quickly and efficiently
contract and the athletes kinetic chain breaks down, preventing optimum
performance.
-
Always
maintain proper posture: head neutral, shoulders back, down and relaxed, and allow
natural spinal curves within optimal postural alignment. (The IFPA recommends that every athlete have a Basic Postural
Assessment by a qualified medical expert.)
-
Drill
athletes to develop both static and dynamic balance.
Sprinting is 5% support and 95% drive.
-
Drill
to increase stride frequency – rate of leg turnover.
Most athletes increase total speed by working on stride frequency.
-
Use
the techniques you have developed in your IFPA Certification courses (Youth
Fitness Instructors, Speed & Agility Coaches, Tennis Conditioning
Specialists and other Sports Conditioning Specialists) to improve running
efficiency and to work on sprinting form and technique.
The students at the IFPA Tennis & Fitness Academy improved their
20-yard dash time by over 25% within 8 weeks of training by utilizing the
exact same drills used in these courses.
Twenty-five percent more speed means they get to many, many more
balls than they did prior to training.
-
Run
sprints at 90-95% of maximum speed and do not be surprised if some of your
athletes sprint their fastest time ever because of greater relaxation and
avoidance of tying-up.
III
The Landing Phase
-
Coach
the athlete to land on their heels. You
will find that as the athlete approaches maximum speed, the athlete will
land flat footed. At maximum speed, the foot will quickly come underneath the
body.
-
Over
striding (the foot landing in front of the body) can actually cause a
braking action that slows the body down.
-
The
leg should extend forward and down with ankle locked in dorsi flexion until
contact.
-
The
pull-through can be practiced by straight-legged shuffles and cycling drills
that teach the athlete the brushing action following contact.
IV
The Recovery Phase
- As the foot leaves the ground simultaneously:
butt kick (driving heel
to buttocks)
dorsi flexion of foot
(toes and foot curl up toward shin)
-
This
is essential to transfer energy from the ground, through the legs, and to the
hip and thighs.
This is also essential to create the shortest lever possible in the leg.
(Short levers move quickly – picture an ice skater initiating a spin.
With arms extended out to the side [laterally], the skater rotates
slowly.
When the skater begins to shorten-the-lever [by bringing the arms into
the body], the skater rotates faster and faster until the skater is a blur with
the shortest lever possible [arms wrapped tightly to the body].)
-
Starting
-
Requires
quickness more than speed.
-
Requires
focus and concentrationmental toughness.
These are highly desired traits for any athlete.
-
Use
a starting position appropriate for your sport. Track sprinters use the 4-point stance. Football players use the 3-or 4-point football stance.
Tennis players use the 2-point stance.
-
Two-point
stance: athlete stands with
feet shoulder width apart, feet parallel, toes facing forward, knees
slightly inside the toes. Knees
should be bent nearly 90, hips in slight posterior pelvic tilt, back
straight, shoulders back, head neutral and eyes looking forward
(approximately 20 yards ahead). Arms
are bent at 90° at the sides and weight should be distributed evenly over
the balls of the feet while maintaining ground contact with the heels.
-
On
GO, the athlete explodes off both feet, driving one leg forward and the
opposite arm back.
-
Athlete
should be nearly falling forward with body lean approaching 70° for
the first three steps. The
initial three steps will be shorter than the athletes normal stride
length.
-
Watch
for two body angles. The line
should be straight from ground to hip at approximately 45°. The second line is from the hip to head initially at 70°
forward lean. Both lines must
be straight at all times.
-
The
athletes will become nearly upright as they approach full speed.
For those who have watched Michael Johnson burn up the track, you
have probably noticed him full upright and appearing to lean slightly back.
This technique obviously works for him, but it is certainly not
recommended for your young athletes.
-
After
the first three steps, stride length increases to the athlete’s ideal
length.
-
Athletes
must be coached to accelerate all the way through the finish line.
-
World-class
athletes take up to 60-70 meters to achieve maximum speed.
Your athlete will unlikely achieve maximum speed in as short a
distance as 20-40 yards.
-
General Notes
-
For
tennis players, use the 20-yard dash
for the majority of your speed work. The average distance a tennis player runs for a shot is 4
meters (less than 5 yards).
-
Twenty-yards is the distance
from the baseline to the opposite court service line.
-
Since almost all tennis
courts are built on a grade to help with drainage, your athlete can get some
over-speed training by running down hill and resisted training by running up
hill.
-
Follow the drill work outline
in the IFPA Youth Fitness Instructors, Speed & Agility Coaches, Tennis
Conditioning Specialists and other Sports Conditioning Specialists courses
to correct any form and technique faults exhibited by your athletes.
-
Remember, it takes time to
develop proper form and technique. Use
patience and encouragement to help your athletes to get it right.
-
In order to make your tennis
players the best they can be, you must first make the best athlete they can
be. Spend time working on a
basic fitness foundation, first to develop athleticism, and then focus on
sports performance. Only then
will your athlete be able to develop into the optimum tennis player.
