The aim of this study is to analyze sprint demands, the ability to repeat sprints and the possible differences between the playing periods of rugby-7 players, considering their playing position. A total of 21 players (age 21.2 ± 2.4) grouped by specific positions (forwards: n = 9; 166.3 ± 12.6 cm; 65.4 ± 7.2 kg; and backs :n = 12; 163.4 ± 9.8cm; 61.7 ± 4.1 kg) were monitored in official competition tournaments, using a global positioning system (GPS). To determine a sprint, an individual threshold of 61% of the maximum speed of each player was considered. The results show that, when analyzing the group of players (p <.05), there are significant differences in the maximum speed (27.0 ± 2.10 vs 24.7 ± 1.65), in maximum speed in competition (25.9 ± 2.34 vs 21.9 ± 2.59), threshold of sprint (16.4 ± 1.29 vs 15.0 ± 1.0), sprint number (6.83 ± 1.88 vs 4.54 ± 1.44), distance traveled to sprint (166.0 ± 15.64 vs 135 ± 13.94), and repeated sprint (1.82 ± .76 vs. 1.11 ± .31). Significant differences were found between both periods of play (p <.05), observing a considerable decrease of the maximum speed in competition, the number of sprints, distance traveled to sprints, and repeated sprints during the second half. The use of relative thresholds increases the number of sprints. The differences in playing positions can help us to better understand the demands of competition and optimize training planning.
