Hop skip and jump your way to becoming a faster runner.

 In Running training

Most runners spend almost 100% of their training time actually running. This is based on the mistaken belief that if you want to become a better runner then you should simply run more.

The reason this is misguided is that our running technique and efficiency is dependant on the strength and flexibility of the muscles, tendons, ligaments and fascia of our body. If we take this as set in stone and unchangeable then running more is the only way to improve your ability to run. However this is not set in stone , we have the ability to change the strength and flexibility of our body and therefore change the way we run.

Run faster with less effort
One aspect of running that many people ignore is the elasticity of our tendons and how we can use this to our advantage. If you watch elite runners you will notice they seem to float across the ground barely touching the surface whereas slower runners tend to land heavily and have to propel themselves from the ground with great effort.

Elite runners have short ground contact time which maximises the use of elastic energy whereas the long ground contact time of the slower runners means elastic energy is lost and can’t be reused.

What is Elastic Energy?
Elastic energy is the energy absorbed by the muscles, tendons, ligaments and fascia of the body when they are subjected to a dynamic load. In running this occurs in two places, when we land and when the trailing leg finishes extending behind us and starts coming forward.

Upon landing the foot is momentarily stationary whilst the knee continues to travel forward. This places the calf muscles, Achilles tendon and ligaments and tendons of the foot under stretch. If your ground contact time is relatively quick then this stretch functions very similarly to when you stretch a rubber band. i.e. after stretching a rubber band , if you let it go it flings forward. The stretch placed on the calf and achilles tendon can propel you forward with no effort required on your behalf.

The effort comes from the stretch in the first place.In running this stretch is given to you by the effect of gravity, the reaction with the ground upon landing and the forwards momentum of the leg. It doesn’t require any additional energy. In fact 50% of the energy absorbed by the foot, ankle and calf can be reused to propel you from the ground. The catch is that this energy is only available for a short period of time. If you delay in releasing the energy, instead of propelling you forward, the energy is dissipated through heat.

This doesn’t just happen in the calf muscles and Achilles tendon, it also happens throughout the whole body to varying degrees. Today we will focus on the lower leg since that is where the biggest gains are to be found.

How can I make use of this free energy?
Keeping ground contact time to a minimum is important, as is training the muscles and tendons to become more efficient at using elastic energy.

Ground contact time is dependant on a number of variables including speed, stride length, stride cadence and the elastic properties of your body. For any given distance we cant change your speed since you are already running as fast as you can. Stride length, cadence and the elastic properties of your body we can change.

Stride length and Cadence
These two are intrinsically linked. The longer your stride length the slower your cadence for a particular speed and vice versa. The problem with a long stride length occurs if the foot lands forward of your centre of gravity. This will result in a longer ground contact time and a loss of elastic energy to heat. Aiming for a cadence of around 90 per minute (i.e. your right foot should hit the ground approx 90 times per minute) is a good place to start. If you are very tall or short then adjust this figure accordingly

Elastic Properties of your Body
To train the elastic component we need to perform exercises that have a short ground contact time. A great place to start is a simple 3 dimensional jumping, skipping and hopping routine

Running is a 3 dimensional activity
Although we run forwards , each of our joints travels through three planes of movement. For example if we look at what happens to the shin bone (tibia) when the foot hits the ground we notice that due to the foot pronating the tibia rotates inwards, travels towards the midline of the body and travels forwards over the foot. This 3 dimensional movement occurs in every joint from the foot to the neck. Unless we load the body in three dimensions to replicate the demands of running we will never fully maximize the benefits of our training.

A simple example to illustrate this point is that if you stand on your right leg and hop to the left you are driving the foot into pronation, simulating what happens when you land when you run but with greater intensity. If you then hop back to the right you drive the foot through supination which simulates what happens at pushoff. Moving sideways involves a greater pronation and supination force than hopping forward and back. Isn’t the point of a conditioning program to create greater strength than is required in your sport so that when you go back to your sport everything feels easier?

Start with jumping as this places less strain on the body. Progress slowly and increase the total number of ground contacts by no more than 10% each week.

To perform this routine stand on an imaginary clock face such that you are at the centre.

1. Jump to 12 o’clock and back to the centre
2. Jump to 6 o’clock and back to the centre
3. Jump to 3 o’clock and back to the centre
4. Jump to 9 o’clock and back to the centre

Repeat this but this time land so that your feet point at an angle to the left
Repeat again so that your feet land at an angle to the right

For example you will jump to 12 o’clock but your feet will point 45 degrees or so to the left.

Try and keep the jumps small but with very short ground contact time. Begin with one jump in each direction and progress to 3-5.

Once you can do this comfortably the next stage is what we call a Jop – its a cross between a jump and a hop. Start on two legs and land on one then hop back to two legs.

Repeat the whole process until you are comfortable doing 3-5 rounds

Now you are ready for hops. Start off with one hop in each direction and progress to 3-5.

How to progress from hops
Do this routine no more than three times a week, sometimes two will be enough depending on how much other running you are doing. Build up slowly and focus on very short ground contact time. If you start to fatigue and find that your ground contact time is increasing then stop and rest.

This routine is a good introduction into plyometric training in three planes but should be progressed as your body adapts.

One way to progress is to add additional jumps before returning to the start position. i.e instead of jumping forward and then immediately backwards, jump forward three times and then backward three times. You can also do this for all the other directions.

    Thanks for the article! I agree that incorporating jumping/hopping can have great benefit to a runner, what are your thoughts on plyometric workouts-too much for a runner to take on/risk injury or a good cross training activity?

      Hi Sarah – plyometrics have a reputation for being very demanding on the body and should be approached with caution and for exercises like depth jumps, hops for distance, hopping/jumping over hurdles etc this is true but simply doing very small jumps as shown on the video is a very low level exercise that wont load up the body much at all and is a great introduction to plyometrics.

      Increasing the elastic recoil of the tendons on the lower leg should be a major goal of all runners and these make a great starting exercise to do that.

      So would argue that its a good cross traiing activity as long as it is introduced very gradually
