The following study aims to investigate the effects of fluid consumption during a simulated hockey cycle test on physiological performance parameters. Fluid losses and voluntary fluid intake was measured in 30 colligate female hockey players aged 20 ± 0.82 years. Subjects were weighed before and after each game. Heart rate was also monitored. The observed value of 480 ml·h¯¹ and an optimal value of 900 ml·h¯¹, suggested by the ACSM (1996), was used in the laboratory to assess physiological differences. Under the observed condition body mass decreased by -0.13 ± 0.05 Kg (mean ± s), -0.23% body mass. In comparison with the ingestion of the recommended volume of water subjects body mass increased by 0.50 ± 0.14 Kg (mean ± s), 0.86% body mass. Body mass losses were significantly different (P < 0.05). Core, mean skin and body temperatures tended to be lower under the greater volume of fluid although these factors were not significant. Core temperature did however remain stable under the recommended fluid condition whereas a significant increase occurred when less water was consumed. No significance between fluid conditions was calculated with reference to mean heart rate values. Dehydration and problems that are associated with it did not occur, concluding that players were sufficiently aware of their fluid needs. Although the variation was great suggesting many players need to increase their knowledge and understanding of the importance of hydration status.
