AB  - Bigg, JL, Gamble, ASD, Vermeulen, TF, Bigg, LM, and Spriet, LL. Sweat loss and 
      fluid intake of female varsity ice hockey players during on-ice practices and 
      games. J Strength Cond Res 34(2): 389-395, 2020-Sweat losses of  approximately 1.5-2% body mass 
      (BM) during exercise impairs athletic performance in stop and go sports such as 
      ice hockey. The study examined the pre-exercise hydration status, sweat loss, 
      fluid and carbohydrate (CHO) intake, and sodium balance of female hockey players. 
      Twenty-four female varsity hockey players were tested during 2 practices and 4 
      games. Data analyses were performed using a level of significance of p </= 0.05. 
      Over 70% of players arrived at the practices and  approximately 50% of players arrived at the 
      game mildly dehydrated. Before the high- (P1) and low-intensity (P2) practices, 
      players consumed an average of 0.19 +/- 0.14 and 0.15 +/- 0.13 L. Before the games, 
      mean fluid intake was 0.39 +/- 0.19 L. The sweat rate during P1 was significantly 
      greater than P2 (p = 0.006), but there was no significant difference in total 
      fluid intake between practices (p = 0.279). Consequently, the average BM loss for 
      P1 was significantly greater than that for P2 (p = 0.016). Sweat loss during 
      games was 1.01 +/- 0.29 L and fluid intake was 0.70 +/- 0.43 L, resulting in minimal 
      BM losses (<1% BM for all players). CHO intake during games was 39.2 +/- 22.8 g, 
      with 19/20 players consuming CHO before or during the intermissions of the game. 
      Sweat sodium losses were 0.64 +/- 0.34 and 0.32 +/- 0.18 g.h for P1 and P2, and 0.83 
      +/- 0.38 g during the game. In conclusion, female ice hockey players replaced the 
      fluid they lost through sweat during practices and games and maintained adequate 
      hydration. Players also consumed adequate CHO during games from the CHO 
      containing food and drinks provided.
