Dietary Intake and Supplement Use in Female Master Cyclists and Runners
Abstract
This study compared the dietary intakes of supplementing (SA) and non-supplementing athletes (NSA). Twenty-five female master athletes (mean age = 50.4 yr) participated in the study (SA = 16, NSA = 9). Four-day diet records were analyzed using Nutritionist V. Statistical significance (p < .005) was determined by independent t tests. No significant differences were observed in intakes of kilocalories (SA = 2079 ± 628 kcals, NSA = 2001 ± 435 kcals), protein (SA = 104 ± 75 g, NSA = 84 ± 35 g), fat (SA = 65 ± 39 g, NSA = 61 ± 22 g), or carbohydrates (SA = 269 ± 112 g, NSA = 277 ± 43 g). Mean intakes exceeded Dietary Reference Intake (DRI) guidelines for all micro-nutrients except calcium and vitamin E (NSA = 79% and 87% of DRI, respectively). SA had significantly greater total intakes than NSA for calcium (p = .0001), magnesium (p = .004), vitamin C (p = .003), and vitamin E (p = .001). Results suggest that female master athletes may rely on dietary supplements rather than nutrient-dense food choices to provide daily nutritional needs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
