Di. Anderson et B. Sidaway, COORDINATION CHANGES ASSOCIATED WITH PRACTICE OF A SOCCER KICK, Research quarterly for exercise and sport, 65(2), 1994, pp. 93-99
The purpose of this study was to examine the changes in coordination a
ssociated with practice of a soccer kick. Video records were collected
on 6 novice, right-footed soccer players prior to and after 2 0 regul
arly scheduled kicking practice sessions. Three experienced players we
re also videotaped for comparison. Movement of the right leg was digit
ized and analyzed using motion analysis software. As a result of pract
ice, subjects were able to significantly increase the maximum resultan
t 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 character
istics of the relative motions of the hip and knee and quantitatively
through three different timing variables. The results provide some sup
port for Bernstein's (1967) ideas on the acquisition of skilled behavi
or as well as for the two-stage model of motor learning proposed by Ne
well (1985).
