Swiss physio warns hydration breaks can harm players

Switzerland's physio Juan Carlos Martínez has warned that the hydration breaks being used at this World Cup can also be harmful. "Las pausas de hidratación pueden ser también perjudiciales," Martínez told Marca, explaining that the stop-start rhythm disrupts players who have built up momentum during long passages of play (1). Cooling the body down abruptly and then asking it to sprint again at full intensity carries its own injury risk, he argued.
