The HSBC Sevens World Series 2010/2011 involved 8 Tournaments over the period 4 December 2010 to 28 May 2011. This report summarises the key results obtained for the 12 core teams taking part in all 8 Tournaments and for 2 teams taking part in 5 of the Tournaments.
The study was conducted in accordance with the IRB approved consensus statement on definitions and procedures for injury surveillance studies in rugby union.
98 match injuries (Backs: 61; Forwards: 37) were reported by the 14 teams during 965.8 player-match-hours (Backs: 551.9; Forwards: 413.9).
Incidence of injury:
101.5 injuries/1000 player-hours (Backs: 110.5; Forwards: 89.4); 0.18 injuries/team-match.
[2008/2009 – Incidence: 106.2 injuries/1000 player-match-hours; 0.18 injuries/team-match]
Severity of injury:
Mean - 34.1 days (Backs: 31.8; Forwards: 37.8); Median – 26 days (Backs: 26; Forwards: 31).
[2008/2009 – Mean: 45.0 days; Median: 24 days]
There were no statistically significant differences (p<0.05) in the incidence, severity, location, type or cause of injury for forwards or backs in the 2010/11 Rugby Sevens Series compared with the results reported for the 2008/09 Series. Knee ligament injuries and hamstring injuries remained the most common injuries. There were fewer ACL injuries in 2010/2011 compared to 2008/2009, which resulted in a (non-significant) reduction in the mean severity of injury.
The results obtained from the 2010/2011 HSBC Sevens World Series are in close agreement with the results obtained from the 2008/2009 Sevens Series. The intention is that the results obtained during the 2010/2011 HSBC Sevens World Series will be combined with the results collected during the HSBC Sevens World Series in 2011/12 to provide a statistically more powerful study and to enable a more detailed analysis of the risks of injury in Rugby Sevens to be published.
