Ways to improve the dorsiflexion and plantar flexion action of
the foot.
Les Archer explains some exercises that will help to reduce your foot/ground contact time and
improve your speed
It is a well known fact that the dorsiflexion and plantar flexion
action of the foot, is a characteristic of sprinters. To improve on the working
capacity of the tibialis anterior, extensor digitorum longus, peroneus longus,
soleus and gastrocnemius that does most of this work they have to be
strengthened and have a greater capacity to apply force faster.
Contact time
The dorsiflexion action is not merely a lift of the toes, but
rather a lifting of the front part of the foot. The plantar flexion action is
not just a downward movement of the foot; it has to be done in such a manner
that it applies maximum force against the ground in the shortest possible
time.
Basically we are trying to reduce the athlete's ground contact
time and thus help improve on speed. The more time you spend on the ground
applying force the longer it takes and time is not something that a sprinter
has plenty of during a race.
The following are just a few ways to improve on this:
Seated foot up
3 to 4 sets of 30 lifts per foot at varied pace.
Standing foot lifts
3 to 4 sets of 30 lifts per foot. As balance plays role here, it
can also help improve your stability. Make sure your toes 'flip' upwards every
time your foot leaves the ground. Do this at varied speed.
Walking with foot lifts (small steps)
Every time you lift your foot up moving forward, make sure you
lift your foot up and land on the front part of your foot. Throughout this
exercise you stay on your toes. Walk distances of 15 to 20 metres, 3 to 4
repetitions. Once the skill has been mastered, walk faster with every training
session. Keep your knees stiff. Once the athlete has mastered it, do the same
in a speed ladder.
Jogging with foot lifts (small steps to long steps)
Do this with stiff knees and "pulling" with the hamstrings and
calf muscles to move forward. Dorsiflex the foot every time it lifts off the
ground to take another step. Do 3 to 4 reps over distances ranging from 15 to
35 metres. It should also be done in the speed ladder.
Skipping
This is a very common training method that will enhance the
dorsiflexion and plantar flexion. Important to note that the foot lifts up
every time it leaves the ground. Start with 30 touch downs and work it up to
100. It can also be done against time.
Short jumps (static or dynamic forward movement, mini
hurdles)
Do 3 to 4 sets of 10 to 20 jumps and lift the feet after every
touchdown. Dynamic jumps - work from 15 to 35 metres with the same action.
IMPORTANT: Try not to bend the knees too much as this will only slow the action
down.
Summary
The above exercises are just a few thoughts. It is however
important for sprinters to do this type of training at least twice per week in
the general preparation phase and once per week during the specific preparation
phase.
