Heatstroke countermeasures

  • We ask that everyone kindly brings their own caps, hats, drinks and other items/measures to counter the effects of hot weather.
  • We will keep monitoring the heat stroke index throughout training time.
  • SIRC will prepare items such as water spray bottles and sports sodium tablets. 
  • We will set breaks for water and rest, while closely watching out for the physical condition of children taking part in training.
  • If there is excessive exposure to the sun at the training location and training becomes difficult/dangerous, we will adapt training contents and location accordingly, and find shady areas or take a rest in the room with air conditioning, in order to secure everyone’s health and safety.
