We investigated the pattern of head movement duringbaseball battingin eightskilled players and nine unskilled novices, using a high-speed video camera. The two directions of head movement were analyzed as an X-axis (from the home plate to the pitcher's plate) and Z-axis (vertical downward). On the X-axis, peak latency, peak value, the distance from the peak to the value at bat-ball impact, and data variability were compared between the two groups. On the Z-axis, peak latency, downward distance, and data variability were analyzed. Peak latencyon the X-axisoccurred significantly earlier in baseball players than novices (p < 0.001), and the difference between the minimum peak and impact was significantly larger in the players (p < 0.05). The variability inpeak latency on the X-axis was significantly larger in the novices (p < 0.05). The variability in peak value on the Z-axis was also significantly larger in the novices (p < 0.05). Our findings showed that the significant differences in head movement between the two groups should help baseball players, beginners, coaches, and strength and conditioning professionals to improve performance, be effectively applied to actual practice, and enhance coaching for batting. |
