Original paperInfluence of environmental and ground conditions on injury risk in rugby league
Section snippets
Subjects
One hundred and fifty-six semi-professional rugby league players participated in this study. Injuries were prospectively recorded from training sessions and competitive matches played over two consecutive competitive seasons. The seasons lasted from December to September inclusive, with matches played from January to September, inclusive.
Matches and training sessions
A total of 55 competitive rounds of matches (which included 137 matches) were played over the two seasons. All trial matches were 60 min in duration. Fixture
Training and match injuries
Table 1 presents descriptive statistics for the injury-related variables. The incidence of injury was higher in matches than in training sessions. There were approximately ten times more injuries in matches (30.75 per match) than in training sessions (3.56 per training session). Similarly, the injury rate per 1000 match exposure hours (860.62) was approximately 13 times more than the injury rate per 1000 training session exposure hours (64.54). Furthermore, the greater mean number of injuries
Discussion
This study is the first to formally investigate the influence of environmental and ground conditions on injury risk in rugby league players. The results of this study demonstrate that: (1) environmental variables affect ground conditions, with grounds typically softer when temperature and relative humidity are higher, and during conditions of greater rainfall; (2) injuries are generally not related to environmental conditions, although a higher 365-day rainfall is associated with fewer
Practical implications
- •
Hard ground conditions and a low annual rainfall are associated with a greater injury risk in rugby league.
- •
During dry conditions, additional irrigation of grounds may reduce the incidence of rugby league injuries.
