Sprinting Technique: The Key to Increasing Your Speed

Mens 100M in Osaka

The genetic makeup of an athlete may bless them with natural speed, but without working on proper sprinting mechanics an athlete will never reach his or her full potential.

This means speed can be taught and all athletes have the potential to increase their speed through their sprinting technique.

Mastering proper sprinting technique not only allows for an athlete to run faster but also reduces the risk of injury caused by poor sprinting mechanics.

You could spend weeks working on top speed without seeing any improvement, whilst focused and attentive time spent on sprint form could potentially increase your speed within a few hours. 

For the sake of this article we will focus on horizontal sprinting across 100m.

Obviously for other sprint events and team sports there will be more detailed and more event/sport specific technical elements (bend running, multi-directional, stop-start movement etc.) but this article will provide a good basis of information that can be applied to some extent across all forms of sprinting.  

Article Overview
  • Sprinting mechanics during acceleration.
  • Sprinting technique during maximum velocity.
  • Exercises you can perform to improve your  sprinting technique. 
  • Sprint technique drills you can implement into your warm-up.

For faster sprint times it is important to limit the amount of time that your foot spends in contact with the ground during each stride.

This is why sprinters run on the balls of their feet and sprint spikes all have the spikes positioned on the forefoot.

Force production is another important aspect to generate speed when making contact with the ground. The greater the force you apply into the ground, the greater return of impulse production, which creates greater speed.

Longer foot-to-ground contact times will allow for greater force generation and impulse production.

So which is more advantageous? Minimum foot-to-ground contact times or long ground contact times to generate a greater force? 

Well the goal is to cover the required distance in the shortest time possible. Therefore, although a longer contact time allows for a greater force, it is not favourable to create such force by this means.

Yes, you will have more powerful strides, but ultimately it will slow you down.

Therefore the key is to apply the optimal amount of force possible into the ground during the limited amount of time that contact is made.

Another thing to consider when accelerating is the point of foot-to-ground contact in relation to the athletes centre of mass.

You want the point of contact to be behind your centre of mass so that there will be less ground contact time. See example here.

This is why it's important to stay low and drive out the blocks, rather than immediately transferring into an upright position.

Take care not to overextend your stride as you will not be able to produce as much force during ground contact and the hamstring muscles will be more susceptible to injury. 

Maximum Velocity Sprinting

During maximum velocity, as with the acceleration phase, shorter ground contact times are linked with better performance.

Again, this can be achieved through applying optimal vertical forces during ground contact.

This will lead to increased speed because you will be able to generate a great enough force impulse to overcome gravity and bound off the ground more rapidly.

One question that is always asked is whether an athlete should focus on increasing their stride frequency or stride length?

Ultimately this will depend on the athlete and their running style.

However, top sprinters can increase their stride frequencies during peak sprinting without decreasing stride length if they apply peak vertical forces and maintain a good sprinting technique.

This is why it's so important for coaches and athletes to understand acting forces on the body during the phases of a 100m sprint.

This understanding will allow for the improvement and development of each phase without negatively affecting the other.

In the acceleration phase, it was beneficial to have the foot behind the centre of mass.

Bringing the foot back during maximum velocity may only be beneficial to a certain point, after which it will become detrimental to performance and increase deceleration by causing the upper body to lean forward.

A good tip is to make sure that when the foot makes contact with the ground, it’s placed under the hip.

Sprinting Technique: The stride cycle

Touchdown ⇨ Toe off ⇨ Flight ⇨ Touchdown 

⇦ (one complete stride cycle)

The stride cycle begins at the touchdown phase.

At the point of touchdown, a sprinter loses momentum and slows down due to the breaking effect.

This is simply where the foot makes its initial contact with the ground.

It's here that the ground contact time that we have been discussing begins,.

It ends after the toe off phase, where force is produced when pushing off the surface.

This then leads to the flight phase where neither foot is in contact with the ground, and ends with the second touchdown as the rear leg becomes the lead. 

Factors That Affect Your Sprinting Technique

Relaxation

A lot of the time you will see athletes tense their whole body whilst sprinting.

This is a red flag in relation to technique. 

It could be down to nerves but is most likely due to trying too hard to generate force and exert power.

This causes unwanted tension in the body and will lead to poor form.

By over-tensing, the body wastes energy, becomes stiff and is unable to move fluently.

Posture

Good posture is essential for sprinting! 

Many athletes have a tendency to lean forward by over-flexing at the hips.

 A slight tilt is recommended, but leaning too far forward will slow you down and ultimately affect your sprinting mechanics.  

A good way to ensure you have good sprinting posture is to make sure that all technique drills are completed with perfect form (A skip, B skip etc.).

Poor from during your technique drills will transfer into your sprinting technique, so its highly important that they are performed correctly.

Focus on keeping your back straight, head neutral with your spine (this will keep your head above your shoulders) and look straight ahead.

Simple Way to Improve Your Posture and Strength

A great exercise that I get my athletes to perform are back extensions.

Performing this exercise regularly increases trunk strength and generally improves physical fitness.

Back extensions target your erector spinae which contains parallel sets of muscles that run down the spine from the base of the neck to the sacrum.

 These muscles control extension and flexion of the vertebral column and can increase optimal posture of the spine when performing sprints.

Back extensions also engage the hamstrings and strengthen other muscles which allow you to become stronger and keep the torso erect when sprinting.

Arm Movement

Your arms play a vital role when sprinting.

The arms help to propel the legs,  which will lead to you sprinting faster.

I heard sprinting legend Carl Lewis once say he uses the cue “elbow to the sky, thumb to the eye” to ensure his athletes are moving their arms correctly.

I like this a lot. It’s catchy and easy for my athletes to remember.

As mentioned, for fluidity, it's important to stay relaxed. Relaxation in the arms comes from dropped shoulders and no tension in the hand or fist.

This will help you achieve a synchronised rhythm with your legs.

Stride Length

Be careful when opening up your stride when trying to increase the length of ground covered.

As mentioned, over-striding means you will generate less power during ground contact, which will increase the rate at which you decelerate.

It also puts a lot of strain on the hamstring muscles, increasing your risk of injury. 

Try to complete every sprint cycle in a circular motion where you are aiming to keep your knees parallel with the ground, and your feet dorsiflexed towards your shins.

Sprint Starts

Perfecting your sprint starts (especially when using blocks) is arguably the most important aspect of the drive phase as it will affect your overall efficiency throughout the race.

It’s important to practice your starts separately so that you are comfortable using the blocks, moving efficiently and reacting to the gun. 

Exercises to Improve Your Sprinting Technique

When it comes to sprinting technique there are many drills you can practice which will help you with your form.

Here I will tell you a couple of training methods you can use that will be beneficial to all athletes who want to improve their speed and technique.

These methods are applied throughout many sports.

Sled Sprints

sled sprints

When pushing or pulling a sled you will see that the position you obtain is very similar to when driving out of the blocks.

Using a sled is a great way to reinforce this positioning which can help improve your start out of the blocks.

 Don’t make the mistake of loading the sled with lots of weight. 

The purpose here is to practice your running stride, not to see how much weight you can shift!

Focus on gradually increasing your stride length as you build momentum, leaning forward and pushing powerfully off the balls of the feet during each stride. 

Don’t push the sled too far.

Like in the acceleration phase of a sprint, you should drive the sled forward for about 30-50m. Repeat this for around 10-20 reps depending on your fitness levels.

You can increase the amount of reps as necessary.

Hill Sprints

Hill sprints are perfect for improving your acceleration.

The incline causes the body to automatically lean forward when sprinting up the hill.

To make it up you will really have to drive the knees up high and you’ll be forced to run on the balls of your feet.

Don’t worry too much about how steep the hill is but aim for a 15% incline.

Sprint up the hill, then slowly walk back down and repeat.

Do this for a total of 5-10 reps for 2-5 sets.

Again this depends on your fitness levels.

Try not to complete these at a high intensity (above 75%) otherwise you will struggle to complete the workout.

Aim for 5-8 minutes rest between sets, depending on how many reps you perform.

Shoulders

  • Don't shrug your shoulders. They should be kept low, not up by your ears.

Hands and arms

  • Run with open palm (if you naturally run with a closed fist, stay relaxed and don't clench your fists).
  • Remember “Elbow to the sky, thumb to the eye.”
  • Sync arms with legs.

Torso

  • Remain upright during maximum velocity. Flexing or extending at the hip will limit your range of motion.

Lower body:

  • Run on the balls of your feet and push off with your toes.
  • Keep your stride long but comfortable. Over-striding means less power and unnecessary stress on the hamstrings.
  • Focus on rapid turnover of sprint cycles with knees parallel to the ground.
