Sprinting is a motion that requires large coordination from the physique. The limbs should transfer in excellent rhythm with optimum synchronization of the muscle tissue. There should even be a clean transmission of the neurological indicators despatched all through the physique.
No motive to fret! The physique does all of it by itself!
There are lots of elements which are missed whereas sprinting. Many of those oversights are normally as a result of physique doing them for us. The opposite motive for lots of oversights is that, as coaches, we prefer to deal with the larger items. Trainers sometimes deal with the large blocks of pace coaching: method, power of the big muscle teams, and mobility via our foremost joints.
One of many oversights I need to handle at present is the shortage of consideration given to the hip flexor group.
The hip flexor is a gaggle of muscle tissue made up of the iliacus and iliopsoas and supported by the rectus femoris and sartorius muscle tissue. The hip flexor group is liable for flexing the hips or elevating the knee towards the shoulders.
As you’ll be able to think about, this motion is important for motion. Even when strolling, this muscle group has to elevate the thigh with each step. You may as well think about how a lot work this muscle group does throughout athletic occasions – by repeatedly lifting the leg and doing it in a robust and explosive method when the athlete must speed up.
The hip flexor group is extra than simply the flexibility to elevate the leg. It’s liable for the physique’s skill to gradual the leg down when it passes behind the physique throughout a step.

This property is named the eccentric pressure of the hip flexor. That’s, the hip flexors’ skill to manage the elongation of the muscle. This muscle high quality can imply the distinction between a quick, environment friendly athlete and an athlete who has main issues in aggressive sports activities.
A number of components play a job right here, together with hip alignment throughout motion, core power and involvement, and toe deviation relative to the middle of gravity. We’ll save all of these things for one more time.
At present I need to deal with how hip flexion power impacts operating type and method. Each time you hear a coach speak about operating mechanics, you hear them consult with mechanics on the back and front. This merely refers to what occurs to the leg on the entrance or again of the physique. As quickly because the leg passes below the physique, it adjustments from a entrance to a again. Because the leg passes below the physique, the foot stays on the bottom for a short while earlier than it begins to maneuver up and behind the hip. This place on the again is the place I need to handle.
The properties and capability of the hip flexor group have a dramatic affect on what occurs on this again place. They have an effect on how far the leg strikes again, how excessive the foot is off the bottom, how far it swings ahead, how lengthy it takes for the leg to maneuver again to the entrance, and eventually how excessive the knee is strikes to the entrance earlier than transferring again down.
Let me provide you with a couple of examples of athletes doing precisely what we’re addressing.
As you’ll be able to see with the athlete on the left, the again leg strikes a lot additional away from the physique than the athlete on the suitable. Additionally, you will discover the alignment of the leg in comparison with if you stepped. Each athletes are approaching landing inside their stride; Nevertheless, one athlete remains to be absolutely stretched behind the physique whereas the opposite athlete is in the course of the swing, getting ready to enter the entrance facet swing. This clearly impacts the timing of the motion. For the athlete on the left, with the again leg prolonged at this level within the step, there may be little or no time to return the leg to the entrance facet place and put together for the subsequent step.
As talked about earlier, a number of components can play a job right here, so I do not need to give the impression that strengthening the hip flexor will repair the whole lot.
Assuming that the athlete can preserve correct posture and align the hips in a impartial place, the hip flexor can now be assessed for effectiveness and management.
If you watch an athlete dash from the facet, you’ll be able to start to guage the vary of movement of the hip flexors. If you happen to observe athletes who’ve an elongated hind leg with a excessive heeled kick just like the one you see on the athlete on the left, you’ll be able to assume that they’re prone to have much less eccentric pressure of their hip flexors. Eccentric refers back to the elongation of a muscle throughout contraction.
Because the foot strikes backward below the physique and within the air, the hip flexor works to gradual the limb in order that it could speed up once more in a distinct path. Athletes with good hip flexion power can convey the leg again below the hip a lot earlier within the stride, as you’ll be able to see within the athlete on the suitable.
The concentric power of the hip flexor can be essential and has a accountability to elevate the knee up earlier than the leg hits the ground. Nevertheless, just like the again heel kick, there are a lot of different components to think about.
Realizing the significance of hip flexor power in operating, what can we do about it? I believe one of the useful and particular issues we will do with our athletes is massive quantity operating workout routines. Whether or not A-series, B-series or C-series – the hip flexor is in nice demand. For this goal, sure technique of strengthening the hip flexor can be utilized over larger distances. There are additionally many different benefits of shaping barrel drills from a technical standpoint that should not be missed.
Different instruments that can be utilized embrace hanging and supine leg raises, in addition to ankle band resistance workout routines. These are all very helpful and may discover their method into an train program. When utilizing these, you also needs to take into account a certain quantity of isometric grips and eccentric actions.
How one can carry out hip flexor coaching is determined by your program and the coaching that’s already being carried out. The important thing, nonetheless, is that or not it’s addressed.
The power of our athletes is an integral a part of their success in pace improvement. Nevertheless, your power shouldn’t be all the time solely cultivated within the weight room.
