TRAINING LOAD, PERFORMANCE AND INJURY RISK IN RUGBY PLAYERS
A rugby player’s ability to perform high-intensity intermittent exercises is associated with a higher training load (TL) which takes place during matches.
The work of coaches and strength and conditioning coaches is to train the players as well as possible to be successful on the pitch. This involves trying to match or even increase the physical, technical and tactical requirements of a match in training tasks. Football players must be prepared for maximum demand scenarios during a match (the so-called “worst-case scenarios”). Understanding the demands of the game seems to be vitally important for improving a player’s capabilities. This is why we are interested to know what will football look like in the future. We must anticipate this during training to prepare the players as well as possible.
Several studies published in recent years give us some clues on what the game will be like in the near future.1,2,3 Wallace and Norton (2014) studied the evolution of the game by taking the World Cup Finals from 1966 to 2010 as an example. According to their results, it is possible to simulate what a football match will look like in the future by using different regression models for five-game indicators:
The real-time of game play decreased significantly in the period 1966–2010, going from 64.23% to 53.66%. In 2030 this value could be 48.74%. The ball speed increased noticeably in the period 1966–2010: almost 1.20 m/s. If this trend is maintained, it will reach 9.73 m/s in 2030. The frequency of passes per minute increased from 10.75 passes in 1966 to 14.71 in 2010. In 2030 it could rise to 16.51 passes per minute. The duration of free kicks to the goal as well as those not, have also significantly increased. Players spend more time to take free kicks, especially those on goal. In 2026 it is expected for a free-kick to take 74.79 seconds, compared to the 38.12 in 1966.
The physical performance profile has also changed in recent years. According to various studies,4,5 the total distance covered by football players is similar now to 10 years ago. However, the number of sprints and high-intensity actions has increased, and the distance covered during these efforts has decreased in recent seasons. In other words, more interventions at high intensity but with shorter duration and distance.
Ultimately, it seems that football will continue to evolve towards a faster game, where the technical level of the players will be higher, and where high-intensity efforts will be more of a determining factor. Game time will progressively decrease until there is more time without the players playing than time with the ball in play. Additionally, dead ball situations will gain more importance. It will become a more intermittent sport. Coaches, strength and conditioning coaches and other members of the coaching staff will have to bear this evolution in mind in order to prepare the players for matches in the best way possible.

Mental abilities, although not yet fully appreciated, are already considered a relevant part of performance. But their importance could go beyond that: Do they also influence the injury risk, including recurrence, once the player returns to play?
Although several studies have tried to evaluate the characteristics of the risk of injury in handball players, they have been unable to reach sufficiently reliable conclusions. A new study of all the FC Barcelona handball categories has attempted to shed more light on the subject.
Although there are several studies on this topic, many of them have analyzed these demands by looking at just a few variables or using very broad timeframes. A new study completed by physical trainers from F.C. Barcelona has analyzed several of these details more closely.
An article published in The Orthopaedic Journal of Sports Medicine —in which members of the club’s medical services participated— now suggests to consider the detailed structure of the area affected, and treating the extracellular matrix as an essential player in the prognosis of the injury.
In this article, Tim Gabbett and his team provide a user-friendly guide for practitioners when describing the general purpose of load management to coaches.
For the first time, it has been demonstrated that it does not take months of training to significantly improve both muscle volume and strength; instead, two weeks of an appropriate exercise are enough.
Training using eccentric exercises is important to prevent possible damage. However, intensive training can also cause muscle damage, so it is critical to be vigilant in order to keep injury risk to an absolute minimum.
Cardiovascular endurance manifests as a moderator of the load result to which the athlete is exposed.
Through the use of computer vision we can identify some shortcomings in the body orientation of players in different game situations.
