INLINE SPEED SKATING
The technique of in-line skating is very similar to that of ice skating, however, the increased friction results in the achievement of lower speeds.
The basic position consists in aligning three "points": the knee, shoulder and toe of the shoe. These points must be aligned with an angle of 100°-110 ° degrees of the knee, and the back lowered accordingly. At high speeds the back will lower more. The shoe must be placed perpendicular to the ground, and shoes distance must have a width that does not exceed basin width. The arms move (in all kinds of thrust) alternately in the legs, that is: when to push the right leg, left arm moves forward until you get in line to the opposite shoulder, while the right stretches behind and vice versa.
The normal straight push can be divided into seven phases: translocation of gravity, landing, sliding, pushing the inner wire, push the wire outside, detachment and recovery. After pushing with one leg, you move the weight on the other completely and begins to fall back on the other leg. The other leg is recovering, passing near the shoe still on the ground with a movement ¼ circumference. When the leg recovers, the other simultaneously pushes in turn, and only when it is almost fully extended, the other lands perpendicularly to the ground.
The movement is equal to that of the normal one in a straight line, but as soon as the foot lands pushes the leg slightly inward, then (when the other leg has finished pushing), complete the push as mentioned above and vice versa.
The trolleying is a step aimed at the deceleration curve. You may need this technique to counter the centrifugal force, to set or correct a trajectory, effettuae or overtaking. The trolleying comes first, trying to equally distribute the weight, with both shoes to the ground, and then sloping towards the inside of the curve: in this way is loaded most of the inner leg (the foot extension must be ahead of the one exterior of a wheel).
The crossover step is a step aimed at maintaining the increase in cornering speeds. The movement is divided into two sub-movements: the thrust with the outer leg, which also determines the inclination at the entrance of the curve, and the push with the shoe interior. The push with the inner shoe must go in the direction of the curve: when the leg is fully extended, the other leg (which in the meantime is recovering) touches the ground, pushing in turn, as indicated above, and the inner leg recovers to return ready to push.
