Coordination Changes Associated with Practice of a Soccer Kick

Abstract

The purpose of this study was to examine the changes in coordination associated with practice of a soccer kick. Video records were collected on 6 novice, right-footed soccer players prior to and after 20 regularly scheduled kicking practice sessions. Three experienced players were also videotaped for comparison. Movement of the right leg was digitized and analyzed using motion analysis software. As a result of practice, subjects were able to significantly increase the maximum resultant linear velocity of the foot, and these increases were accompanied by changes in the pattern of coordination underlying the movement. These changes were assessed qualitatively through the topological characteristics of the relative motions of the hip and knee and quantitatively through three different timing variables. The results provide some support for Bernstein's (1967) ideas on the acquisition of skilled behavior as well as for the two-stage model of motor learning proposed by Newell (1985).

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

“…No presente estudo foram relatadas diferenças signifi cativas para o desempenho do chute de fi nalização no futsal comparando-se grupos de indiví-duos com diferentes níveis de desempenho dentro da modalidade, o que corrobora com achados da literatura específi ca para o futebol [12][13][14][15] e reforça a ideia de que a prática induz mudanças nos padrões de coordenação 27 . Anderson e Sidaway 27 haviam reportado que novatos apresentam uma velocidade linear resultante do pé inferior a jogadores experientes no futebol.…”

“…Além disso, a infl uência das variáveis que cercam a velocidade da bola também não foi investigada para o futsal nestes diferentes níveis, em categorias de formação. Investigações conduzidas com o futebol evidenciam que mudanças fundamentais ocorrem nos padrões de coordenação durante o chute como resultado da prática 27 . Entretanto isso ainda permanece no plano inferencial para o futsal, ou seja, não existem evidências que confi rmem essa premissa.…”

Lower Limb Coordination and Stiffness During Landing from Volleyball Block Jumps

“…The coordination between any two oscillators is the degree of coupling (relative timing or relative phasing) between these two oscillators. Since a landing manoeuvre is a discrete action, angle -angle plots are likely to provide the most appropriate illustration (qualitative) of relative motion, where the angle of one joint is plotted against the angle of another (Anderson and Sidaway 1994), and time series -based discrete relative phase (DRP) is likely to provide the most appropriate measure (quantitative) of relative timing between the hip, knee and ankle joints. DRP analysis determines the relative timing between key events in a movement cycle, such as the maximum angle of two different joints.…”

Stereotypy, flexibility and coordination: key concepts in behavioral functional morphology

“…This can be distinguished from changes to the pattern of coordination in the face of a treatment. Coordination and its relationship to performance are understudied in the comparative literature, although this topic has been explored in more depth in the human literature (Anderson and Sideaway, 1994;Egan et al, 2007;Post et al, 2000).…”
