Kinetic comparison of a side-foot soccer kick between experienced and inexperienced players

Abstract

The aim of this study was to identify critical kinetic variables that lead to increased ball velocity during a side-foot passing kick in soccer. Seven experienced male soccer players and eight inexperienced players participated in the experiment. They were instructed to perform side-foot kicks along the ground with maximum effort with an eye on the target line. The joint angles, angular velocities, and torques of the kicking leg were determined based on the three-dimensional kinematic data. The mean ball speed of the experienced group (21.4 +/- 1.5 m/s) was significantly faster than that of the inexperienced group (16.0 +/- 1.0m/s; P < 0.001). The motions of the inexperienced players tended to be less dynamic than those of the experienced players. The most noticeable difference in the kinetics of the kick was found in the hip flexion torque throughout the back-swing phase until the leg-cocking phase. The mean peak value of the experienced group (168 +/- 20 N x or m) was significantly greater than that of the inexperienced group (94 +/- 17 N x or m; P < 0.001). To increase ball speed during a side-foot passing kick, the generation of hip-flexion torque during the earlier stage of kicking is critical.

Velocidade da bola no chute no futsal: comparação entre garotos com diferentes níveis de desempenho e correlação de variáveis preditoras do desempenho

“…Além disso, o corpo pode assumir posturas diferentes de acordo com o alvo e velocidade da bola 4 . Estudos anteriormente realizados encontraram positivas correlações entre a velocidade do pé imediatamente antes do momento do impacto com a bola na velocidade da bola imediatamente após o contato [8][9][10] . Adicionalmente, o comportamento da velocidade da bola após um chute de força máxima do membro dominante e não dominante pode ser afetado principalmente pelas diferenças na velocidade do pé e na mecânica de colisão 11 .…”

“…Joint moments on the instep kick in the present research were similar to values previously reported in literature in amateur, highly skilled and professional male soccer players (Kellis & Katis, 2007;Navandar et al, 2013), but higher than those reported for experienced male soccer players in the side-foot kick (Kawamoto et al, 2007) and in post-pubertal female soccer players (Lyle et al, 2011) The difference could be explained to the difference in maturity and skill level of the players (Katis et al, 2015) and the type of kick (Nunome et al, 2002).…”

“…The knee continues to flex and reaches a peak flexion (Kawamoto et al, 2007) ( Figure 5). This is known as the leg cocking phase (Kawamoto et al, 2007;Lees, 2013).…”

“…This is known as the backswing phase (Kawamoto, Miyagi, Ohashi , & Fukashiro, 2007;Lees, 2013). During the backswing phase, the hip extends with a velocity of 3-5 rad/s (Levanon & Dapena, 1998;Nunome et al, 2002).…”

“…This is known as the leg cocking phase (Kawamoto et al, 2007;Lees, 2013). The term refers to the flexion of the knee as the thigh is brought forwards during the pre-contact phase (Nunome et al, 2002).…”
