Abstract/OtherAbstract:
Beverage palatability is known to influence fluid consumption during exercise and may positively influence hydration status and help to prevent fatigue, heat illness and decreased performance. PURPOSE: The aims of this review were to evaluate the effect of beverage temperature on fluid intake during exercise and investigate the influence of beverage temperature on palatability. METHODS: Citations from multiple databases were searched from the earliest record to November 2010 using the terms 'beverage', 'fluid' or 'water' and 'palatability', 'preference', 'feeding' and 'drinking behaviour' and 'temperature'. Included studies (n=13) needed to use adult (≥18yr) human participants, have beverage temperatures ≤50°C and measure consumption during exercise and/or palatability. RESULTS: All studies (n=8) reporting palatability indicated cold (0- 10°C) or cool (10-22°C) beverages were preferred to warmer (control, ≥22°C). A meta-analysis on studies (n=5) reporting fluid consumption revealed that participants consumed ~50% (effect size=1.4, 0.75 to 2.04, 95% CI) more cold/cool beverages than control during exercise. Sub-analysis of studies assessing hydration status (n=4) when consuming cool/cold compared to warm beverages demonstrated that dehydration during exercise was reduced by 1.3% of body weight (1.6 to 0.9%, 95% CI) (p<0.001). CONCLUSION: Cool beverage temperatures (<22°C) significantly increased fluid palatability, consumption and hydration during exercise compared to control (≥22°C).
