J Mot Behav.: Effects of mental imagery styles on shoulder and hip rotations during preparation of pirouettes.
To analyze the individual behavior in spatial navigation especially for pirouette preparations (complete whole-body rotations), the authors studied horizontal shoulder-hip interactions under two constraints: postural (right and left supporting legs [SL]) and spatial (clockwise [CW] and counterclockwise [CCW]). They performed kinematic analysis at the start and end of the shoulder-hip horizontal rotations (run-up) with regard to imagery of motor actions. On the basis of the Vividness of Movement Imagery Questionnaire they classified eight female expert ballet dancers and seven untrained female participants according to their movement imagery style (kinesthetic and visual). At the run-up's end, the shoulders initiated the turn independently of SL, but differently depending on training: CW for dancers and CCW for untrained participants (their commonly preferred direction). Kinesthetic and mixed imagery styles prevailed in dancers, whereas a mixed style alone appeared among untrained participants. Thus, dance training enhances the imagery of kinesthetic sensation and influences the choice of spatial direction, facilitating the body-space interaction.
