Background

The COVID-19 pandemic has resulted in global disruption to many sports. There are a number of challenges in returning to sport, especially given the unprecedented duration of time that athletes have not been able to train or compete in normal environments(1), the potential health risk to athletes, their coaches, support staff, the wider public, and the limited evidence base available to inform decisions. Every sport will carry different infection risks, given the specific match demands and training requirements(2). Furthermore, considerations regarding the return to training and match play will be greatly influenced by the national impact of COVID-19(3). A good example is the comparison of United Kingdom (COVID-19 mortality of >42,000), vs. Australia and New Zealand (COVID-19 mortality of <150)(4). In particular, New Zealand has now eliminated SARS-CoV-2, and rugby and other sports are now occurring ‘as normal’.

On the 29th of May the International Journal of sports medicine published on line the attached article, with the easing of Pandemic conditions the following article should be read by sports alevels when returning to play.

Abstract: The COVID-19 pandemic in 2020 has resulted in widespread training disruption in many sports. Some athletes have access to facilities and equipment, while others have limited or no access, severely limiting their training practices. A primary concern is that the maintenance of key physical qualities (e. g. strength, power, high-speed running ability, acceleration, deceleration and change of direction), game-specific contact skills (e. g. tackling) and decision-making ability, are challenged, impacting performance and injury risk on resumption of training and competition.

In extended periods of reduced training, without targeted intervention, changes in body composition and function can be profound. However, there are strategies that can dramatically mitigate potential losses, including resistance training to failure with lighter loads, plyometric training, exposure to high-speed running to ensure appropriate hamstring conditioning, and nutritional intervention.

Athletes may require psychological support given the challenges associated with isolation and a change in regular training routine. While training restrictions may result in a decrease in some physical and psychological qualities, athletes can return in a positive state following an enforced period of rest and recovery. On return to training, the focus should be on progression of all aspects of training, taking into account the status of individual athletes.

An interesting study published in May 2020 by the BMJ in Sports Exercise and Medicine concerning artificial pitches:

Artificial turf can be defined as ‘a surface of synthetic fibres made to look like natural grass’. Since its introduction in 1965, safety concerns have been raised over its use as a playing surface in competitive contact sports. The higher number of knee and ankle injuries occurring on artificial turf has been established.

Despite these safety concerns, an ongoing replacement of natural grass with synthetic turf continues to occur in contact sport.

The aim of this review was to compare the incidence of head injuries and concussion on both artificial turf and natural grass in those competitive contact sports (of any standard) using both surfaces. From this, the risk of such injuries can be directly compared on either playing surface.

What is already known?
► With increasing awareness of head injuries in contact sports, the diagnosis of concussion is becoming more common. Artificial turf is frequently used as a
playing surface for contact sports. There remains no consensus on whether playing surface contributes to the incidence of significant head injury.

What are the new findings?
► Analysis of the limited publications on artificial turf playing surface demonstrates a lower incidence of concussion and head injury in competitive contact sports. On subgroup analysis, this effect is most marked in rugby and American football, with no significant association of playing surface on the incidence of head injury or concussion in soccer.

This systematic review demonstrates an overall lower concussion and head injury rate occurring on artificial turf in competitive contact sports combined, yet when assessing the sports (soccer, American football and rugby) individually, the link between head injury and concussion with playing surface type is not as clear.

Future research in this area would be important to ascertain reasons for this result.

Further examination on what other factors exist that could lead to lower head injury and concussion rates on artificial turf in contact sports should be established. This may include: number
of collisions on artificial turf, the incidence of surface to head contact, the maintenance of the artificial turf as well as its surface properties including temperature and HIC (Head Injury Criterion).
