Referees need 21 days of training before returning to competitions

The fitness instructor of the CONMEBOL Referees Committee, Juan Carlos Albarracin, affirms that professional football referees need at least 21 days of training to regain form before facing the resumption of tournaments, since the physical demands are equal to that of footballers in official competitions.
"They will require a pre-season to avoid injuries, such as contractures and tears during the games. It will be essential for the referees to carry out a pre-season of up to 21 days as soon as the group activities are resumed to regain mobility, resistance work, because all this will be very fundamental. At home they have been able to carry out training to develop strength, functional work, but not everyone has equipment to be able to perform in the best way as everyone would like."
