A rugby scrum is a key part of rugby. It allows players and their opponents to collide at incredible speeds. This makes a rugby scrum very dangerous. Because they were too violent and placed too much strain on forwards, the old scrums were eventually banned. Now, scrums are regulated by the rules of the Rugby Union.
During a sustained push phase of a rugby scrum, there are biomechanical demands
Rugby players have to be able to sustain a sustained push phase during a scrum. This phase requires players to exert force from many positions. Specifically, the force exerted a player by this phase varies depending upon their stance and body positioning. But, the collective force exerted a group should be greater then the sums of these individual contributions.
A systematic literature analysis was performed to investigate the biomechanical demands made during this stage of the scrum. Pubmed, EBSCO Academic Search Premier, CINAHL, SPORTDiscus, and Google Scholar were searched for articles that reported the force produced during simulated rugby scrums. A narrative synthesis method was used in order to extract the data from the articles.
The effects of playing level on rugby scrumforce
While there isn't a clear correlation between playing level and the rugby scrum force produced, some evidence suggests that the number forwards in a pack can influence the force they produce. When normalized for the total weight of the pack, the force produced by winning teams can be as high as 1081 N higher than those that lose. The advantage of winning packs is that they tend to push the other pack approximately 1.5 meters back, giving them the ability to win possession.
The sustained pushing phase produces the greatest force, with the strongest differences being in elite and professional packs. This could be because these packs have a higher mass. However, the standard deviations difference is smaller which means that there is less variability. Furthermore, playing level and pack mass increase the maximum force generated.
Changes in rules regarding rugby scrums
The history of rugby scrums has changed significantly over the years. They are no longer medieval battles in which opposing hookers fought for the ball, but they have evolved to be more professional. Although the scrum is an important part the game, the rules have been updated to decrease injury risk to players. Although the scrum will be called by a referee, possession may now be changed at the referee’s option. The law of engagement has also changed to prevent dangerous contact between front rows. This means that contact must be made at a distance of less than one-arm's length between the front rows.
There are also a number of changes to the rules for the scrum, including a maximum length of 1.5 meters for a scrum push. This will apply to both contested as well uncontested scrums. This will help increase the time the ball is still in play.
Analyse data collected through a systematic literature search on rugby scrum
Scrum is the most commonly reported performance indicator in rugby union, with the most articles published between 2005-2010. However, the most common time period investigated was the period between 2003 and 2007. The 2006 season was the most studied, followed by the Super Rugby Championship.
With a higher incidence of injuries among forwards than in backs, a greater proportion of players had to miss two or more days of play. More than half of injuries were sustained in tackling and running in play.
