This study investigated the effects of a coordination exercise program on quantitative and qualitative changes of throwing and catching ability with the subjects of 5 and 6-year-old 30 preschool children. A4-week control period and a 4-week exercise period were separately set. The exercise program was conducted for 40 minutes a day following the instruction guidance, during 8 days over 4 weeks. The subjects performed motion capacity tests (standing broad jump, side jump) and ball handling tests (control, catching,tennis ball handling) in each period. We evaluated the throwing and catching motions by using five typical developmental stages of motion patterns. As the results, we found a statistically significant increase in the side jump, catching, tennis ball handling and score evaluation for throwing and catching motions in the exercise period compared to the control period. The same results were obtained in both genders. These results suggested that, the coordination exercise program focused on basic ball handling technique may be beneficial to enhance the agility and ball handling capacity in preschool boys and girls aged 5-6, who need an adequate exercise instruction to improve their throwing and catching motions.

The purpose of this study was to clarify visual search behavior and decision time in continuous decision tasks of the toss direction and spike course in volleyball. Volleyball players, ball game players, and non-ball game players (10 in each group) wearing eye-movement trackers watched video images of combination attacks from three directions and made decision about whether the toss direction was left or right and the spike course was straight or cross. The results revealed the following:     1) In comparison to ball game and non-ball game players, volleyball players had a faster decision time for toss direction and the spike course. Furthermore, volleyball players made excellent decision-making even in situations involving continuous decisions.     2) Volleyball players have quiet eye characteristics. In other words, they gaze for long periods at the body, including the face, and torso of players, including setters and spikers who pass the ball.     3) It was revealed that after deciding the toss direction, volleyball players quickly glance at the spiker before the spiker steps in with both his feet and decide the spike course from the opponentʼs upper-body turn or arm swing.
