Differences in time motion and intensity during final elite rugby 7's
Abstract
Methods. The data were obtained from 8 assessments during the course of 2 games in 4 men players and 4 women players. For this, we have used a global positioning system (GPS) with 1Hz frequency.
Results. Data reveals that women 7's players cover for a final an average of 2343.4±283 m (115.1 m·min-1), with no significant differences between the first (1199.45±132.4 m) and second half (1143.97±154.2 m). For its part, men 7's players cover for a final an average of 2486.30±165.8 m (121.4 m·min-1), with no significant differences between the first (1203.78±101.85 m) and second half (1282.52±86.83 m). There are significant differences between the two categories in terms of meters covered in zone 3 (12-14 km·h-1, p<0.05) and in zones 5 and 6 (18-20 and >20 km·h-1, p<0.05 and p<0.01 respectively). The women 7's player obtains an average maximum heart rate during the final of 185.2±4.5 beats per minute for 188.6±6.5 the men 7's players. The average heart rate was 163.2±4 for women and 167.6±3 for men. Women remained a 91% of the game over 80% of their maximum heart rate, while men were over 80% of their maximum heart rate 74% of the game. The work to rest ratio in women and men was 1:0.4 and 1:0.41, respectively.
Conclusion. The results of this study provide objective support to the idea that rugby 7's is played at a higher pace than other forms of rugby, suggesting that the physical demands of rugby 7's are different from those related to other rugby codes.
