The acceleration of the kicking leg, in addition to the resulting velocity at impact, is concluded by the muscle forces being applied by the kicker. It has been accounted that the speed of the ball at impact was directly proportional to the calculated strength of his themes. The release velocity of the ball in regards to its timing had the strongest relationship to the maximal torque formed during the i. hip flexion, ii. Knee extension and iii. Short ankle alleviating in the kicking leg. In addition the relationship between the maximal resultant forces of the thigh and shank and the release velocity of the ball was tough. The link between the release velocity of the ball and age was elevated however less than with weight or height. Consequently the augment of the body mass means boost in the mass of the foot and this by design increases the release velocity of the ball in the kick.
A significant ability in the game of soccer is the capability to kick the ball powerfully and precisely. The instep kick is the kick which is most frequently used for the utmost force as well as distance, as for a shot on goal or a long pass. The force for the long kick is put on from the run-up into the ball, and from the movements of a maximum number of body parts. These comprise hip and trunk rotation, in addition to hip flexion, knee extension and ankle plantarflexion to shape a rigid surface for impact.
The kick with run-up creates longer and more potent kicks than the standing kick. This is due to the augmented momentum of the kicker at impact.
