Children's use of the bearing angle in interceptive actions.

The authors investigated the effect of ball velocity and walking direction on children's adherence to the constant bearing angle (CBA) strategy. Children (N = 20) approached a moving ball to manually intercept it at a predefined target area. Results revealed that 10- to 12-year-olds adhered more than 5- to 7-year-olds to the CBA strategy.

Postural adjustments and bearing angle use in interceptive actions.

The experiment investigates the effect of ball velocity and walking direction on the adherence to the bearing angle (BA) strategy in adults. Adult participants (N=12) approached a moving ball in order to manually intercept it at a predefined target area. Results revealed that during locomotion the BA strategy was implemented, but on reaching the point of interception, this strategy broke down and the BA strategy of the wrist compensated for the movement requirements relative to the ball velocity and approach angle.
