Updated Fluid Recommendations For Marathon Runners

The International Marathon Medical Directors Association (IMMDA) recently revised its fluid replacement guidelines for those who run marathon races. The updated recommendations, reported in the Journal of Clinical Sports Medicine (2006; 16, 283–92), emphasize self-regulation rather than rigid guidelines, say the authors of the new IMMDA Position Statement.

The report gives approximations of fluid replacement needs according to a marathon runner’s personal finish time, race pace and fluid rate. Also included are

  • a fluid calculator to estimate sweat rate;
  • tips for race day; and
  • cautions for avoiding hyponatremia, a dangerous condition caused by too much fluid replacement.

Here’s a taste of what’s cooking in the world of nutrition:

Faith-based foods are making believers out of industry trend experts, who say that consumers are seeking spirituality in the supermarket; witness the debut of products that cite Psalms on the labels and include free prayer booklets in the packaging.

Japanese supermarkets are being redesigned to appeal to older shoppers with physical limitations; the new store layouts provide lower shelves for easier reach and wider aisles that can accommodate wheelchairs and walkers.

Diet and nutrition services are going mobile, with companies like Cingular Wireless, Verizon Wireless and Sprint Nexel now offering popular diets that can be accessed by any cell phone or personal digital assistant.

Bottles of Kombucha are all the rage among Hollywood insiders; the Chinese tea is cultured for 30 days to allegedly produce “active enzymes” and “antioxidants,” according to the product’s label. Users should know that in 1995 the U.S. Food and Drug Administration warned that home-brewed versions of the tea may be prone to microbiological contamination if manufactured under nonsterile conditions. WebMD reports that some cases of liver toxicity and pulmonary edema have been linked to the tea.
