F ALL athletics<br />

O<br />

events, the triple<br />

jump is widely<br />

acknowledged by<br />

sports scientists as one of the<br />

most physically demanding.<br />

Research at the University of<br />

Iowa a few years ago showed<br />

that, at the landing between the<br />

hop and step phases, the force<br />

exerted by a triple jumper on<br />

the ground can be the<br />

equivalent of up to 22 times<br />

their bodyweight – just about<br />

the highest measured force that<br />

a human limb is exposed to<br />

during any intentional activity.<br />

According to Dr Sam Allen,<br />

a lecturer in biomechanics at<br />

Loughborough University, that’s<br />

the equivalent of an athlete<br />

briefly weighing 1.7 tonnes,<br />

and having to stand on one<br />

leg at that time. Writing on the<br />

website theconversation.com<br />

last year, Dr Allen explained how<br />

published papers have proven<br />

triple jumpers develop unusually<br />

thick thigh and shin bones to<br />

enable them to withstand the<br />

force of the event.<br />

But the event is as<br />

technically demanding as it is<br />

physically and errors in posture<br />

or execution can cost an athlete<br />

dearly. “Physics dictates that<br />

the higher in the air an athlete<br />

travels, the further they will jump<br />

– provided they don’t sacrifice<br />

their speed,” said Dr Allen. “So,<br />

the athlete needs to carefully<br />

balance the speed and the<br />

height of their jump, in order to<br />

perform really well. Because of<br />

this, technique is an extremely<br />

important aspect of the triple<br />

jump.”<br />

Add the mental fortitude that<br />

is required to come down the<br />

track at 9.5-10.5 metres per<br />

second, then to take off and<br />

land on the same leg and it<br />

becomes evident that bravery<br />

is essential to take up this<br />

event. So what does it take to<br />

perfect the stages of this most<br />

challenging event?<br />
