Kinematic Analysis of the Instep Kick in Youth Soccer Players

Abstract

We attempted to establish which applied kinematic variables significantly contributed to the efficiency of the instep kick motion in soccer. The study sample comprised 13 boys (age: 13 ± 0.5 yrs; body mass: 41.50 ± 8.40 kg; body height: 151.46 ± 5.93 cm) from the FC Sloboda school of soccer. Each participant performed three kicks with maximum strength that were video recorded with two synchronized cameras (Casio Ex-F1) positioned 12 m away from the place of the kick. Data were collected by analyzing the video recordings of each kick. Data processing was performed using the APAS motion analysis system (Ariel Dynamics Inc., San Diego, CA). On the basis of the forward selection method of multiple regression analysis, we determined the correlations between the prediction variables and the selected criteria (speed of the ball; p = 0.01). On the basis of the regression coefficients, it was concluded that two variables significantly contributed to the speed of the ball: speed of the foot of the kicking leg at the time of contact with the ball (p = 0.01) and the distance between the angle support leg and center of the ball (“foot posterior displacement”) (p = 0.01). In order to achieve the best possible technical performance and, therefore, a higher speed of the ball, soccer players must pay attention to two important elements during training. First, it is necessary to position the support leg as close to the ball as possible and, second, maximize the force used in the initial phases of the kick to achieve a high speed of the kicking foot.

“…Kicking is the most often and commonly studied skill in soccer (Kellis, Katis, & Gissis, 2004). Although there are many variants in this technique due to the type of player, the velocity and the position of the strike, the purpose and intent of the move, the version most widely reported in the literature is the instep kick of the static ball at maximum speed (Lees, 1996); (Nunome, Asai, Yasuo, & Sakurai, 2003); (Kellis, Katis, & Gissis, 2004); (Kellis & Katis, 2007); (Scurr & Hall, 2009); (Kapidzic, Huremovic, & Biberovic, 2014).…”

“…The study's first objective was to observe the associationamong lower body power (squat jump) and sprints (10-meter and 30-meter), COD speed (arrowhead agility test), static balance (Centre of Pressure) and velocity of ball. The second objective of the research was to compare the ball velocity when kicked with the dominant limb as well as the non-dominant limb from different approach angles (Nunome, Asai, Yasuo, & Sakurai, 2003); (Kellis, Katis, & Gissis, 2004); (Kellis & Katis, 2007); (Kapidzic, Huremovic, & Biberovic, 2014); (Nunome, Inoue, Watanabe, Iga, & Akima, 2018). The third objectiveof the research was to comparethe activation of selected kicking limbmusclesand supporting limbmuscles when the ball was kicked through different angles of approachwith both the dominant limb and non-dominant limb, viz.…”

Biomechanics Analysis of Side Header in Soccer Players

“…angle support leg and center of the ball. [9] Bjelica attempted to gain relevant knowledge about important differences with respect to compare accuracy of instep kicking between preferred and non-preferred leg depending on the different intensity in a resting state, and in a state of fatigue. The findings clearly demonstrated that the young football players have much more uniformed legs at the expense of accuracy when fatigued and kick the ball with the maximal intensity.…”

Parâmetros cinemáticos em jovens jogadores de futebol: análise do chute em contexto experimental e desempenho de corrida, dinâmica tática e habilidades técnicas durante jogos oficiais

“…Compreender o desenvolvimento de parâmetros de desempenho em jovens jogadores de futebol dos grupos de idade sub-9 até sub-20, por procedimentos da cinemática.

Uma clássica revisão de literatura sobre o tema aponta para a existência de uma lacuna entre pesquisa em Biomecânica do esporte e o processo de ensino-aprendizagem-treinamento (21).…”
