This study aimed to quantify player movements during first-class cricket fielding. Using real-time computerised time-motion analysis the entire on-field activities of 27 in-fielders were observed for 10-over periods; 9 during each of the morning, afternoon and evening sessions of first-class cricket. In addition 8 first-class cricketers performed 15m speed trials between timing gates to provide velocity multipliers for distance estimation. Overall, players changed movement every 6.4+/-1.1s (mean+/-S.D.) and fielded the ball 0.5+/-0.4 times per over. Stationary and walking activity represented 94.2+/-2.4% of match time. High-intensity (HI) activity represented 1.6+/-0.8% of match time with mean burst and recovery durations of 1.3+/-0.3 and 99.8+/-94.5s, respectively. Repeated HI bouts (at least 3 bursts with less than 21s mean recovery) occurred 1.2 times per 10-over period. Fielders covered an estimated 15.5km per day. In conclusion, first-class fielding entails less HI activity than other team sports such as soccer and hockey. However, fielders are required to cover large distances in a day, but over 77% of these distances are covered by walking.
本研究旨在量化一流板球防守期间球员的移动情况。通过实时计算机化时间动作分析，观察了27名内场球员在10局比赛期间的全部场上活动；在一流板球比赛的上午、下午和晚上各时段中，各观察9名球员。此外，8名一流板球运动员在计时门之间进行了15米速度测试，以提供用于距离估算的速度乘数。总体而言，球员每6.4±1.1秒（平均值±标准差）改变一次移动，每局接球0.5±0.4次。静止和行走活动占比赛时间的94.2±2.4%。高强度（HI）活动占比赛时间的1.6±0.8%，平均爆发和恢复持续时间分别为1.3±0.3秒和99.8±94.5秒。每10局比赛中重复出现高强度活动（至少3次爆发，平均恢复时间少于21秒）的情况发生1.2次。内场球员每天估计跑动15.5公里。总之，一流板球防守中的高强度活动比足球和曲棍球等其他团队运动要少。然而，内场球员一天需要跑动很长距离，但其中超过77%的距离是通过步行完成的。
