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.

At the recent South of England Championships the senior athletes performed well - so well in fact that we won three of the four horizontal jumps ....
Men's Long Jump Paul jumped 7.21m for victory but had 3 no jumps which were long. Hopefully he'll get one in over the next few weeks. Paul was also operating off a shorter approach, so once he gets this longer run-up nailed down he should be able to jump that bit further also. Triple jumper Jonathan was also long jumping - he managed 6.84m but had a no jump over 7m. Jonathan is well capable of a 7.5m jump and indeed his Pb is 7.33m. If he did more comps the chances are that he'd seriously improve on this. Women's long jump Sarah opened with 6.19m with a safe-is jump and then elated from this (her third best jump ever) went for it. It's often the case that trying that bit harder does not bring the results one would imagine and unfortunately rather like Paul, she fouled some rather long jumps. Still this again showed good promise for the season ahead. Women's triple jump Allison came 6th with 12.02. We were disappointed with this as she has been showing better from in training and has not had the fortune to 'hit' one in a comp. Hopefully, she'll get close to 13m before the season is out. Men's triple jump Potentially 'our' best performance came in the men's triple where Jonathan got legally back over 16m for the first time this year. his best of 16.28m was set in the equivalent meeting last year. It was a shame that the competition became a bit of a speed one as there were only two other jumpers in the field and it must have been one of the quickest competitions I have witnessed. I guess it was testament to Jonathan's and the other's fitness that the jumps did not deteriorate as the quick-fire competition progressed. Jonathan was consistent with a number of jumps between 15.80 and 16.03. The latter ranking him fourth at the moment in the UK. We're looking forward for challenging for a higher ranking. Over the next few weeks he and Sarah have a meeting in France and there are also some league meetings for them and the others, so watch this space. This Friday 7th I'll be uploading a video on my YouTube channel that goes into more detail about what happened at the Souths - it will be of relevance to those who just want to see the jumps but also to those who may wish to find out a little bit more about "how to compete".
