Abstract: | Male high school football athletes served as subjects (no. = 134; age = 15.0 +/- 1.2 years, range = 12 to 18 years; weight = 67.7 +/- 13.9 kg) (mean +/- standard deviation) in a dietary survey project to characterize nutritional intake from food sources. Dietary intake data were collected using the recall method for 1 weekday during the summer when athletes participated in unsupervised, informal conditioning. Subjects were grouped by age as junior high (JR-HI: 12 to 14 years) or senior high (SR-HI: 15 to 18 years) students. Absolute mean energy and nutrient intakes, except for vitamin A, were statistically greater for SR-HI relative to JR-HI (p less than .02). These findings are consistent with age-related growth on nutritional intake. Mean nutritional intakes from food sources for SR-HI met or exceeded the RDAs. For JR-HI, mean intakes met or exceeded the RDAs except for energy (94% RDA) and zinc (87% RDA). Mean intakes exceeded those of a representative sample of same-age boys in the larger American population. |
