BARBIERI, Fabio A.; SANTIAGO, Paulo R.; GOBBI, Lilian T.  e  CUNHA, Sergio A.. Dominant and non-dominant support limb kinematics variability during futsal kick. Rev. Port. Cien. Desp. [online]. 2008, vol.8, n.1, pp.68-76. ISSN 1645-0523.

The purpose of this study was to examine the performance and hip, knee and ankle movement variability of the support limb in the kick performed with the dominant and non-dominant limb in futsal. Twelve skilled male participants performed five maximal instep kicks with each limb and aimed to hit a fixed target. Their movements were recorded and the images were transferred to a computer, and analysis of the 3D data was made by Dvideow software. The Eigen values of the covariance matrix of the hip, knee and ankle joints of the dominant and non-dominant limb for each time instant were calculated to analyze movement variability. The ratio between the square roots was calculated for each time instant and the cumulative distribution function was used to verify the difference between the sides. The location of the ball related to the target after the kicks was measured for the performance values. The results presented less variability of the knee and ankle joints of the dominant limb at some moments of the kick cycle in comparison to the respective non-dominant joints. The dominant limb presented a better performance and we therefore concluded that performance is influenced by variability.
