Nutrient intake of highly competitive male and female collegiate karate players.
Nutrient intake of 29 male (M Group) and 16 female (F Group) highly competitive collegiate karate players were compared. The results were also compared with the daily energy expenditure (DEE), Japanese recommended dietary allowances (RDAs) or adequate dietary intakes (ADIs). Dietary information was collected using a 3-weekday diet record. Although the M Group showed significantly higher mean %RDAs or %ADIs in iron, vitamin B1, phosphorus, magnesium, and sodium than the F Group, many of the mean %RDAs or %ADIs were below RDAs or ADIs in both groups. The subjects who skipped meals tended to show lower mean %DEE, Japanese %RDAs or %ADIs in minerals and vitamins than the subjects who did not skip in both M and F Groups. The consumption of green and other vegetables and milk and dairy products in both M and F Groups were low. It is concluded that the male and female highly competitive karate players studied in the present study may be at risk of sub-optimal nutrient intake, which increases the potential for nutrient deficiency. The subjects were advised not to skip meals, and to consume a balanced high-carbohydrate, moderate-protein, low-fat diet with increasing green and other vegetables and milk and dairy products to increase mineral, vitamin and dietary fiber intakes.
