已有研究表明,在足球比赛中,助理裁判员对越位判罚的准确率约为94%,失误率为6%。经进一步研究发现,在这些失误中,多数是由于助理裁判员在判罚越位的时间与空间上与实际情况存在差异,在判罚过程中,助理裁判员的移动多为走动与短距离全速跑动等移动状态,助理裁判员在判罚越位时除所处的位置外,移动速度也会影响到判罚越位的质量。 Studies have shown that in football matches, assistant referees have an accuracy of 94% against offsides and a 6% error rate. After further research, we find out that most of these mistakes are due to the differences in time and space between the assistant referee and the actual situation.
