Coaching, jumps, sprints & more
Everything about jumping and sprinting and how to improve your performance
Long jump and triple jump requires reactivity i.e. the ability to transfer from a hop landing into the step as is the case for the triple jump. However, it’s more specific than that as on each contact, for example, when running there is a reaction in the muscles of the ankles legs and hips. You’ll probably know of this as the stretch-reflex which is the key driver of plyometric exercises, such as the drop jump. However, there’s a further aspect that needs to be considered and which is developed via plyometrics and weights for example and that’s leg stiffness.
Basically, the better able your legs are at being able to withstand and return force quickly the greater the leg stiffness. What’s important is that there are three sites at which this leg stiffness can be measured and developed in the legs and that at this limb’s three joints – the ankle, knee and hip.
So, I believe it’s important to develop improved stiffness and therefore reactivity at these joints. So, how do you do this? Well, you do different types of plyometric exercises, for example. You’ll see in the image one of the group members performing a drop jump from a very low height – about 6cm.
In order to get a quick reaction and gain height from the double foot contact they need to use their feet and specifically their ankles. I instruct them to “flick” their feet down on contact to create the extension needed to gain vertical velocity.
If the athlete anticipates the landing and bends their knees in an attempt to power up, the end result is visibly reduced speed and less leg stiffness. We will do 2-4 x6 reps in a session once or twice a week on average across the training year of this exercise.
So, what about stiffness at the hip? We will do straight leg hops and near straight leg bounds. With the former the objective is to propel yourself forward from basically a virtually straight leg. I’ll often say “Like a pogo stick” to the athletes – and then recall that most are too young to know what they are! It’s a case of letting the bounce “happen” on each contact rather than forcing it and using increased knee bend to produce the power.
For knee stiffness then the majority of standard bounds, hops and other plyos will be doing the job … I feel it’s the blend of plyos (and weights) and the emphasis of stiffness at all the joints which contributes to all-over leg stiffness and which will therefore bring about improvement in the jumps and sprints.
