Nutritional characteristics of recreational women runners
1992
Lloyd, T. | Dolence, L.A. | Bartholomew, M.J.
We used three day diet records to determine and compare the nutrient intake in 108 premenopausal recreational runners and 34 control women. Overall, the nutrient intake profiles of the two groups were similar. Using univariate distribution analyses, we observed that over 80% of the runners did not obtain RDA levels of iron, calcium and zinc. We also analyzed the nutrient profiles of the runners by age and by weekly miles run. When studied by age, we observed that the older runners (36 or older) had significantly greater intakes of iron, magnesium, vitamin B6, caffeine and dietary, fiber than those of younger runners. When studied by weekly miles run, we observed that the women who ran more than 8 miles per week had significantly greater intake of caffeine. Those who ran 4-8 miles per week had significantly greater intake of iron, magnesium, vitamin B and dietary fiber. We conclude that suboptimal intake of iron, calcium and zinc is prevalent among recreational women runners.
