Vodafone Fiji 7s coach Ben Ryan has stressed that dehydration is a major problem faced by many athletes in Fiji especially the national sevens side.
Ryan said getting the best energy requirements for training a player is very important.
He stressed that players need to have high quality sleep, intense physical exercise and take a lot of water to help in their general growth.
Meanwhile some of the players who have been given more time to prove themselves for the final selection for Hong Kong are Pio Tuwai, Apisai Domolailai, Emosi Mulevoro, Inia Saravanua and Kitione Taliga.
