The aim of the present study was to evaluate physical activity of football referees and provide information for effective training program referee. Match analysis data was collected from 12 elite (KFA A licence) referees(age: 43year, hight: 175㎝, weight: 73㎏, career: 9.6year). SPSS-PC(ver. 20.0) was used for statistical analysis. Distances according to speed zone were significant differences in high speed running(the first half of the season, 11.51%; the second half of the season, 8.63%), low speed running(the first half of the season, 37.86%; the second half of the season, 30.08%) and walking(the first half of the season, 30.13%; the second half of the season 39.12%) between periods(p<.05). Total distance (the first half of the season, lO208m; the second half of the season, 943m) do not showed any significant difference between periods(p>05). Time duration of activity according to speed zone were also significant differences in low speed running(the first half of the season, 20.25%; the second half of the season, 15.02%) and walking(the first half of the season, 45.28%; the second half of the season, 51.91%) between periods(p<.05). There was no significant difference in total time duration of activity (the first half of the season, 93min 32sec; the second half of the season, 93min 01sec)(p>.05). Significant higher average speed of sprinting(24.89㎞/h, 24.27㎞/h) , high speed running08.47㎞/h, 18.31㎞/h) and jogging(7.40㎞/h, 7.28㎞/h) were observed in the first of the season than the second of the season(p<.05). These results demonstrate that the referees cover more distance and high intensity of movement during the first half of the season due to low fitness burden.
