Application of Novel Inertial Technique to Compare the Kinematics and Kinetics of the Legs in the Soccer Instep Kick

Abstract

Application of Novel Inertial Technique to Compare the Kinematics and Kinetics of the Legs in the Soccer Instep Kick The kinematic and kinetic parameters of dominant and non-dominant legs examined with a new technology on 15 male, university soccer players in the field. A sensor module with special configuration of accelerometers placement, connected to a data logger, which attached to the shank and thigh, was applied to execute four instep kicks in the field. The angular velocity, linear velocity, angular acceleration and Z-axis linear acceleration (p<0.005) of the shank in dominant and non-dominant leg before impact were: 1970 ± 210, 1648 ± 300 °/s; 14.9 ± 3.0, 12.4 ± 2.6 m/s; 586.4 ± 121.9, 498.2 ± 160.4 rad/s2; 5.7 ± 1.7 and 4.0 ± 0.9 gravity, respectively. The leg swing time, force (X) (p<0.001), torque, angular momentum, angular power and angular impulse (p<0.05) of the shank, for dominant and non-dominant leg, before impact were: 271 ± 48 vs. 263 ± 62 msec; 172.4 ± 46.6 vs. 68.7 ± 47.1 N; 133.2 ± 29.8 vs. 111.8 ± 34.9 N.m.; 5.3 ± 1.1 vs. 4.1 ± 1.0 kg.m2/s; 2443 ± 666 vs. 1660 ± 790.1 W; 4.0 ± 0.9 vs. 3.3 ± 1.2 N.s., respectively. Even though there was lower shank angular velocity of the dominant leg compared with reported professional players, similar shape and gradient of the kicking pattern were found in the curves.

Inertial Sensor Technology for Elite Swimming Performance Analysis: A Systematic Review

“…Others have found a similar association, with peak ground reaction force calculated from accelerometer counts during walking and running in children [ 121 ]. This relationship has also been acknowledged in other sporting situations [ 117 , 118 , 122 , 123 , 124 ]. Meamarbashi and Hossaini [ 118 ] measured kinetic parameters such as force, torque and angular impulse with an inertial sensor system to study kicking techniques in soccer and to compare dominant and non-dominant legs, drawing clear parallels with symmetry assessment in swimming.…”

Meamarbashi and Hossaini [ 118 ] measured kinetic parameters such as force, torque and angular impulse with an inertial sensor system to study kicking techniques in soccer and to compare dominant and non-dominant legs, drawing clear parallels with symmetry assessment in swimming. However, force plates and pressure sensors remain the most commonly used tool for kinetic analysis in pool swimming, even for systems that employ inertial sensors [ 71 ].…”

“…Therefore, this avenue of research remains underdeveloped and it would not be advisable to draw conclusions regarding the merits or demerits of these approaches based on the limited information available. Certainly, the use of inertial sensors for measuring joint angular kinematics is commonplace in other sporting situations and high levels of accuracy have been achieved [ 111 , 113 , 116 , 117 , 118 ].…”

Effect of the Physical Effort Levels on the Angular Impact Kinematics When Performing Kicking Accuracy with Instep in the Soccer Junior

“…used on a step box comparing to Hoff Test used in the present study which depends on a procedures more simulating to what is done during the actual practice in soccer game, but the results is partially in agreement with a change in the lower body segement from distal to proximal which indicated to the shift of the motor energy from the distal(thigh) to the proximal(shank and foot) when performing from instep kick in the maximum physical effort comparing to the low level of the physical effort. Also it is in agreement with the scientific study results which was conducted to know the effect of a group of the influences on the kinematics of performing front instep kick in soccer as the effect of increasing the number of kicking trials (Khorasani et al, 2010[33]) or the effect of the preferred method for kicking (Nunome et al, 2012[52];Meamarbashi & Hossaini., 2010 [46]) or the effect of the kicking shape(high, low trajectory) (Prassas et al, 2004[55]) or the effect of the different speed to swing the kicking leg(slow, medium, high) (Dunn & Putnam., 1986[19]) and its results showed that the angular velocity of the foot and shank of the kicking leg was influenced in the impact phase as one important variable which must be noted when studying any effect on the kinematics of front instep kick in soccer (Kellis & Katis., 2007[31]; Dorge et al, 2002[18]) reported the importance of monitoring the minimum and maximum of the angular velocity of lower body segments when studying any influence on performing front instep kick in soccer.…”

Kinematic Analysis of the Instep Kick in Youth Soccer Players

“…Specifically, systems for the kinematic analysis of human movement provide precise measurement of values and parameters of athletes’ movements during performance of any sport technique. Understanding of the biomechanics of kicking in soccer is important for monitoring and correcting performance during the training process ( Meamarbashi and Hossaini, 2010 ). The speed of the ball in an instep kick depends on several factors, including speed of the foot of the kicking leg before contact with the ball, body posture at the moment of kicking the ball, length of the run up to the ball and its angle ( Barfield et al, 2002 ; Stankovic et al, 2004 ; Meamarbashi and Hossaini, 2010 ; Dorge et al, 2002 ).…”
