A rugby scrum, an integral part of rugby, is crucial. It allows players to collide with each other at lightning speed and push their opponents into each others. This makes scrums of rugby dangerous. The old style of scrums ended up being banned. They were too violent and put too strain on the forwards. Rules of the Rugby Union regulate scrums.
Biomechanical demands during the sustained push phase of a rugby scrum
Rugby players have to be able to sustain a sustained push phase during a scrum. Players have to apply force from a variety positions during this phase. The force exerted individually by each player will vary depending on their body position and stance, but the collective force of a group of players should exceed the sum of all these individual contributions.
To investigate the biomechanical demands during this phase of the scrum, a systematic literature review was performed. 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 for extracting data from the articles.
Effects of playing level on rugby scrum force
Although there is no clear relationship between playing level and rugby scrum force, there is some evidence that the number of forwards in a pack may influence the force that they produce. A live scrum shows that the winning teams produce an average of 1081 N more force than the losing ones. They also produce twelve times as much force when the combined weight of all the packs is added. Also, winning teams tend to move the opposition pack around 1.5 meters back, which can give them an advantage when they win possession.
The greatest differences in sustained pushing force are those that are produced during the sustained push phase. Professional and elite packs have the most noticeable differences. This could be because these packs have a higher mass. The difference between standard deviations and absolute force is smaller, which suggests less variability. Further, the maximum force generated decreases with increasing playing level and pack mass.
Rugby scrum rules changed
Rugby scrums have changed considerably over the years, from medieval battles where opposing hookers would fight for control of the ball to the professional game. While the scrum remains a vital part of the game, changes to the rules have been made to reduce the risk of injury to players. The referee will still call a scrum, but possession will now be changed on the fly at the referee's discretion. The law of engagement has also changed to prevent dangerous contact between front rows. This means that the front rows must be separated by less than one arm before contact can be made.
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 applies to both contested scrums and uncontested scrums. This will help to increase the time the ball remains in play.
Analyse data collected through a systematic literature search on rugby scrum
The scrum is the most widely reported performance indicator for rugby union. There have been the most articles published in the period 2005-2010. However, the 2003 to 2007 period was the most popular time period. 2006 was the most investigated season. Super Rugby Championship was also the most frequent played competition.
Injury incidence was higher among forwards than backs, with a greater percentage of players out of the game for two or more days. More than half the injuries occurred while running or tackling.

Paragliding -- Paragliding looks similar to parachuting but paragliders glide through the air rather than falling to the earth. Paragliders launch usually from high mountainsides. They then control the plane with ropes that are attached to the wings. The pilot can then pull the rope from his harness to make the plane land. The parachute automatically opens.
-
Surfing -- Surfers ride waves of water to travel along the ocean floor. Surfers are usually upright when surfing. The board is used as a surfboard. It allows the surfer a way to propel himself forward. He returns to deeper water after the wave recedes.
-
Snowboarding -- Snowboarding is another form of extreme sport. Snowboarders use specialized boards that glide down hills. They also use special bindings to secure their feet to the boards. Snowboards come with wheels to make it easier for riders to slide down the slopes.
-
Skateboarding -- Skateboarding can be described as a mix of rollerblading and skateboarding. Skaters use unique skateboards to navigate ramps, rails, and other obstacles on city streets. In place of rollerblades, skateboards are utilized.

Alpine skiing is the most difficult. Cross-country skiing can be more accessible. The easiest is downhill skiing. Freestyle skiing mixes all three.
Which extreme sport is most dangerous?
