Time motion analysis of international rugby

[摘要] English: This study examined the relationship between the Distance covered, High IntensityDistance covered, and the Percentage Work Rate at High Intensity and how it correlatesto the score and result of each match. This paper attempted to address deficiencies inthe game of rugby and provide a meaningful body of data to determine winning andlosing components that jeopardize matches at senior international level. Eighteenmatches (Test and Super 14) were used to gather data through the Pro zone timemotion analysis program. Calculating the frequency, mean duration and total time spentin activities is fundamental in time motion analysis (McLean, 1992:285-96). The extentof these changes has, however, never been quantified. What is even more important isthat their impact on playing the game has not been evaluated. Teams losing the awaygames, even though they won all components, can be due to home team support,playing conditions, the magnitude of the game, law variations, competition structure andthe team structure played. Time motion analysis is an effective method of quantifyingthe demands of rugby and provides a conceptual framework for the specific physicalpreparation of players. The results of this study showed no significant difference (p <0.05) between the variables (distance covered, high intensity distance covered andpercentage work rate at high intensity) in the winning and losing team. The correlationbetween all the variables (distance covered, r = 0.67 , high intensity distance covered,r = 0.62 and percentage work rate at high intensity, r = 0.54) and winning have practicalimplications. The information obtained from these analyses allows coaches to structuretraining programmes specific to the requirements of the game, and facilitates moreeffective training and improved performance.
