PURPOSE: The aim of this study was to examine the effects of several matches per day on running performance and cardiovascular stress in referees during a National Rugby Sevens Championship. METHODS: Seven referees, who refereed three matches per day, were monitored during 21 matches using GPS. RESULTS: Referees movement patterns were relatively stable from the first to the second match, although a substantial decrease was observed in the second match for maximal and average sprint distance. A substantial decrease in the number of sprints, maximal speed, walking, distance covered at medium intensity, total and >14 km·h-1 distance covered per min was observed in the third match in comparison with the second. Compared with the first match, in the third game referees showed a substantial decrease in maximal and average sprint distance, total, walking, at medium intensity, distance covered >14 km·h-1 and high-intensity running distance. Referees exhibited a substantial decrease in average heart rate, percentage of time >70%HRmax, and percentage of time >90%HRmax in the second match compared with the first. Referees HR responses were relatively stable from the second to the third match except for the heart rate zones between 71-80%HRmax, 81-90%HRmax and Effindex. Substantial differences were observed in the third match in comparison with the first in average heart rate, 81-90%HRmax, >90%HRmax and Effindex. CONCLUSION: This study provides evidence of reduced overall running performance and pronounced reduction in high-intensity running performance during the last match in Rugby Sevens referees when referring three matches within the same day.
