“…Also because it has demonstrated that a small percentage of time of exclusive practice of the non-preferred foot (20 minutes in each 90 minutes of the training session, 3 times a week, for a period of four months) allowed a significant increase in the use of the non-preferred foot during the game. This is consistent with the idea of study 18 that suggests that the increase in the performance of technical skills may be achieved through little structured practice. Nevertheless, further practice leads to a proficient development and therefore several authors suggest that if higher performance is intended, practice should be extended 19 .…”

The functional asymmetry of the lower limbs has been considered an important factor in the performance of soccer players. In this sense, the purpose of this study was to examine the effects of specific technical training for non-preferred foot on its utilization rate during the game; and to investigate if interruption of a technical training programme for the non-preferred foot influences its utilization rate during the game. Fifty young soccer players were randomly divided into two groups: G1 (n=26, 9.50±1.04 years) and G2 (n=24, 9.58±1.02 years). At the beginning of the first 4 months, each player's use of both feet during the game was assessed. The study lasted eight months divided into two periods of four months. In the first training period G1 was subjected to a technical training programme directed to the non-preferred foot, while G2 had no constraints on the use of both feet. At the end of the 4th month the two groups were newly assessed. During the second training period G1 and G2 reversed the training programmes. After the 8 months of training the evaluation of the utilization rate of both feet during small-side games was again performed. The main conclusions of the study were: (i) the technical training of the non-preferred foot allowed significant increases in its utilization rate during small-sided games; (ii) the interruption of such training partially reversed this effect. Thus, technical training for the non-preferred foot should be systematically performed in order to maintain the positive effects induced over functional asymmetry.

“…For example, highly skilled athletes with extensive motor experience, such as elite soccer players, display higher levels of accuracy than non-athletes when faced with changes in task demands such as end point trajectory placement or a moving soccer ball to kick (Egan, Verheul, & Savelsbergh, 2007; Ford, Hodges, Huys, & Williams, 2009). These athletes also display faster reactions times suggesting that they are able to integrate the appropriate sensory cues for a movement and predict the consequences of their results than non-athletes potentially due to extensive experience performing and adapting highly specific action patterns (Montes-Mico, Bueno, Candel, & Pons, 2000; Romeas & Faubert, 2015; Vanttinen, Blomqvist, Luhtanen, & Hakkinen, 2010).…”

While the development and execution of upper extremity motor plans have been well explored, little is known about how individuals plan and execute rapid, goal-directed motor tasks with the lower extremities. Furthermore, the amount of time needed to integrate the proper amount of visual and proprioceptive feedback before being able to accurately execute a goal-directed movement is not well understood; especially in children. Therefore, the purpose of this study was to initially interrogate how the amount of motor planning time provided to a child before movement execution may influence the preparation and execution of a lower leg goal-directed movement. The results displayed that the amount of pre-movement motor planning time provided may influence the reaction time and accuracy of a goal directed leg movement. All subjects in the study had longer reaction times and less accurate movements when no pre-movement motor planning time was provided. In addition, the children had slower reaction times, slower movements, and less accurate movements than the adults for all the presented targets and motor planning times. These results highlight that children may require more time to successfully plan a goal directed movement with the lower extremity. This suggests that children may potentially have less robust internal models than adults for these types of motor skills.

“…Also the present study results are in accordance with the results of the study of (Egan & Verheul & Savelsbergh.,2007 [20]), which revealed differences between kicking stationary ball and movable ball in the knee joint of the kicking leg and the velocity of the toes in favor of kicking the movable ball as it indicated that there is less extension of the knee joint of the kicking leg accompanied with velocity of the kicking leg toes which is larger in kicking the movable ball comparing to the stationary ball.…”

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

Kicking in soccer with accuracy is influenced with a group of factors. It is noted the paucity of the scientific studies which addressed other variables related to the effect of the physical effort levels on the kicking performance. Most of the treatments have done on kicking from stationary situations without paying attention to study kicking performance skill in the moving play situations a simulation to what occurring during the actual practice(the game). Therefore the purpose of this study was to know the effect of the different physical effort levels on the change in the angular kinematics impact when performing kick accuracy of a moving ball with front instep of the foot in soccer players.(N=10) junior soccer players (varsity players) age: 16.8 ±0.55 years, height 173.4 ±7.41 cm., weight 66.7 ±8.65 kg. have completed five levels of physical effort according to Hoff Test(10 min. for each level). In this test the levels were determined based on: running distance(m.), lactic acid concentration in blood (mmol ⁄L), heart rate during the test and on kicking performance(b ⁄min.) and perceiving exertion scale(deg.). The best trial(the most accurate) from four front instep kick trials of a complex skill ending with shooting were analysed by using Motion Track program 3.D. and by using 3 camera(25 HZ). The first camera to the side of the player, the second to the side of the goal, the third behind the player and in front of the goal. The first and third cameras were used to analyze the angular kinematic variables of the impact phase(impact between foot and ball). Second and third cameras to define accuracy level. The results revealed that there were statistical significant differences (P<0.05) between the different physical effort levels in the kinematic variables related to the angular distance variables: angle of knee and hip joints of both kicking and supporting legs and ball release angle and angle of the knee extension and hip flexion of the kicking leg, also to know the kinematic variables relevant to the angular velocity of the variable of: angular velocity of foot and shank of both kicking and supporting legs and ball velocity. It was found a great effect size of these variables in favor of the low and moderate physical effort levels comparing to the high sub-maximum and maximum levels. The present results suggested that Hoff Test protocol which simulate the actual practice(the game)lead to an impairment of kicking performance in soccer because there were functional and physiological changes which in turn changed kicking performance mechanics in soccer.
