Each racer has its own pace that characterizes its rhythm of racing, racing technique and stroke. The racing speed of a racer can be evaluated by analyzing two important parameters: the frequency and the pitch amplitude .
Frequency , the word itself says, is nothing but cadence and therefore the pace of the step. While the pitch amplitude is characterized by both supports, that is, the distance from the support of both feet (dx and sx). Bearing in mind that the technical aspects of the race are discussed, they are highly influenced by the physical characteristics of the subject and can be enclosed in several aspects:
In a study conducted by Prof. Piero Incalza, trainer of some Italian national marathoners and researcher at the Roma Center, presented at the Athletics Magazine No. 3 2008, was able to analyze the pace of travel in long distance runners. "In practice, considering male and female athletes, both top runners and amateurs, it has come to the practical conclusion that the element discriminating in technical evolution in the long run is given by, rather than by the amplitude" !
In practice, it has been noticed that top runners over the amateurs succeed, as they run faster, to increase the pitch frequency than the amplitude, the foot is more responsive and touches several times on the ground with a more flying phase short. In addition, it has been found that long distance distances (Marathon) are crucial to reducing the energy cost of the race, thus minimizing any unnecessary consumption and being able to run for so long with the same technique of running without bumps. By also evaluating two top runners at the same speed, it has been noted that there are those who can consume less energy and have a cheaper wad that will eventually allow them to have the energies indispensable to try to stretch and detach the group. From this we can see the importance of dedicating time in preparing for the technical aspects of the stride and making the most economical as possible.
All aspects of the pitch and pitch abilities can be evaluated during the workouts, we can see how our frequency or amplitude changes according to the pace of travel. It is worth remembering, according to the characteristics mentioned above, that each of us has a frequency and amplitude of the ideal step where it maximizes its potential. If we try to over-modify our natural race we would risk wasting too much energy and not exploiting our best. However, if we always run at the same pace, always doing the same types of training, slow running example, average race, we risk getting the pace of the pitch that is accentuated most in the fast race, where the foot must touch the ground quickly and then immediately Push for the next step.
According to Piero Incalza (Athletics Study No. 3 -2008), " there are several ways to measure the pace of the stroke, count the number of steps in a given time, or time the time taken to make a predetermined number of steps . Example shows the time of 10 supports on the same foot (10 strokes - 20 steps). To know the frequency you divide 20x the time recorded on 10 falcate ".
This simple exercise that each of us can do to test the pace of pitch at different speeds can be experienced by training on the treadmill by increasing the speed of 0.5km / h counting each speed increase to verify and see the modifications Which take place at any variation of rhythm, at any variation in speed, and during each training medium. So when we have a Slow Race program we will know that every minute we have to make "total passes", feeling we will understand that this is the right pace to complete our slow running session. So the advice is to try it out in the moment we run the heating stage where the pace is slower and the freshness of the initial allows us to be able to concentrate on each stroke. From this dissertation it is understood that running regularly and regularly allows us to improve the racing technique, so also the energy consumption of the race is more limited and consequently runs longer and consumes less energy. This is also a practical answer to the fact that to run a marathon is not only important to have a lot of energy at our disposal, but also and above all what we can consume or better save on a technique that is profitable and effective for so many miles.
