Abstract

PURPOSE: To investigate the effect of manipulating the alcohol and sodium content of beer on fluid restoration following exercise. METHOD: Seven male volunteers exercised on a cycle ergometer until 1.96±0.25% body mass (mean±SD) was lost. Participants where then randomly allocated a different beer to consume on four separate occasions. Drinks included a low alcohol beer (2.3% ABV) [LightBeer], a low alcohol beer with 25 mmol·L-1 of added sodium [LightBeer+25], a full strength beer (4.8% ABV) [Beer] or a full strength beer with 25 mmol·L-1 of added sodium [Beer+25]. Volumes consumed were equivalent to 150% of body mass loss during exercise and were consumed over a 1h period. Body mass and urine samples were obtained before and hourly for 4h after beverage consumption. RESULTS: Significantly enhanced net fluid balance was achieved following the LightBeer+25 trial (-1.02±0.35 kg) compared to the Beer (-1.59±0.32 kg) and Beer+25 (-1.64±0.28 kg) treatments. Accumulated urine output was significantly lower in the LightBeer+25 trial (1477±485 mL) compared to the Beer+25 (2101±482 mL) and Beer (2175±372 mL) trials. CONCLUSION: A low alcohol beer with added sodium offers a potential compromise between a beverage with high social acceptance and one which avoids the exacerbated fluid losses observed when consuming full strength beer.
