Contact with SoilYou have to support your foot on the soil slightly ahead of your body, a support very forward would be detrimental to the length of stride and subsequent slow progress in your career. Cundo your leg making contact with the ground knee must have a slight flexion, in order to cushion the impact with the ground, the foot touches with a very slight bending to be slightly accentuated at the moment of impact (kinetic chain buffer) . An excessive flexion increase the time that the foot is in contact with the ground running and seriously damaging a knee flexion short you can cause serious injuries in the knee.
In athletics the time of contact with your foot on the soil is an important factor, especially since seeking speed in the race, we have to find a triathlete running with a contact time somewhat higher because we have no choice. Both the accumulated fatigue and the need to economize in order to complete the proof we make walking speed is not the only variable to take into account.
In general terms I am going faster and jump over less time should be taken on foot on the ground. In the sprint triathlon running technique is based on the tip and less on the heel.
The muscles of our body and especially our legs and is elastic energy accumulated as a rubber when stretches and then released. But this power does not accumulate permanently and seek a trot in which the contact time is sufficient to take the elastic energy is important. Training type multisaltos and careers on the hoof or punta-talón for improving the tenica are important.
The other leg at this stage passes grouped with the pickup foot below the buttocks and tilting ever so, in order to promote the advancement and elevation of the hip. Although covered in the chapter on body posture during the running playing well with the center of gravity for use in our favor and not against us is elementary. When the foot hits the ground (or contact support) and the knee will flex to absorb the impact pelvis down onto the opposite side. This helps aboser impact, as "runners" descent pelvic are confronted by the coordinated action of several muscles. These are (wkipedia) band iliotibial of the leg that takes touch, abductores and stomach. And unlike the flexion of the knees is opposed to the eccentric contraction of the quadriceps.
You brianmac.co.uk Translation:
"As the foot hits the ground, there is also the bending of the knee. This should not be too excessive, so that the leg strength should be developed to ensure stability in and around the knee. There are also some hip movements around the waist. This can be excessive, so the strength exercises for the entire region, especially in the abdomen and lower back are needed. It is very important that this region remains stable, allowing a solid platform from which to lead. "
