2IntroductionFigure skating is a highly competitive and physically demanding sport which requires a special diet and lean physique.Past studies have shown this population suffers from compromised health due to inadequate nutrient intake.Purpose: To examine the contribution of daily meals to the macro/micronutrient intake of elite figure skaters during their competition season.Hypothesis: Breakfast, lunch, dinner, and snacks will contribute equally to the macro/micronutrient intake of the elite figure skaters.
3MethodsSubjectsn= 94 (46 males, 48 females) competitors in the 1999 USFSA National ChampionshipsDietary IntakeThree-day food records were collected 2 weeks prior to the competition.Two non-consecutive weekdays and one weekend dayAnthropometric MeasurementsHeight and weight were measured prior to daily exercise and food consumption.Data AnalysisSPSSMean +/- SEIntake was tested using the general linear model.
4Results Mean BMI: 21.2 (males) and 18.5 (females) Based on the dietary measurements, it appears the figure skaters meet the macronutrient recommendationsDiet CompositionMales: High CHO, AA, Sat TAG, TcholFemales: Low TAG, Tchol, fiberNeither met all micronutrient requirements (folate, Fe, Ca)
5Contribution of meals to the macronutrient and micronutrient intake of elite male figure skaters
6Contribution of meals to the macronutrient and micronutrient intake of elite female figure skaters
7Percent contribution of meals to macronutrient and micronutrient intake of male & female elite figure skaters
8Conclusion Limitations Use of food records as dietary measurements Small sample sizeLength of studySelf-reported dataCannot be certain all dietary needs are being metWhat was learnedConsistent meal patterns may have a significant effect on micro/macronutrient consumption in athletes.Individuals working with athletes may need to provide tips for preparing meals that can be consumed on the run, which will meet their energy needs during training and performance.Athletes should be encouraged to consume more frequent meals and to distribute their energy intake between the meals based on their activity schedules
