背景:测试和评估运动员是必要的,并且应包括表现,身体成分,和营养。这项研究的目的是报告饮食摄入量的评估,V•O2max,D1大学运动员的身体组成,并检查这些评估之间的关系。
方法:通过3天的召回评估饮食摄入量,并与建议进行比较,通过生物电阻抗分析(BIA)评估身体成分(n=48)。使用带有验证bout(n=35)的分级运动测试(GXT)评估了V·O2max。确定了“真实”V·O2max与验证之间的可靠性。进行相关性和回归分析。
结果:能源,碳水化合物,微量营养素摄入量低于建议。GXT和验证的平均V−O2max分别为47.3和47.4mL·kg-1·min-1,分别。虽然膳食摄入量之间的相关性很明显,V•O2max,和身体组成,无脂质量百分比(%FFM)预测V*O2max的36%。
结论:大学运动员没有达到能量和碳水化合物的建议,也没有超过脂肪的建议。维生素D和镁在所有运动中都很低,女性的铁和钙含量较低。V•O2max的范围为35.6至63.0mL·kg-1·min-1,女性低于平均水平,男性达到指定运动的典型值。评估D1运动员可以为体育营养师提供指导,教练,以及力量和调理专家来跟踪和监测运动员的营养。
BACKGROUND: Testing and evaluating
athletes is necessary and should include performance, body composition, and nutrition. The purpose of this study was to report assessments of dietary intake, V˙O2max, and body composition in D1 collegiate
athletes and examine relationships between these assessments.
METHODS: Dietary intake was assessed with 3-day recalls and compared to recommendations, and body composition was assessed via bioelectrical impedance analysis (BIA) (n = 48). V˙O2max was evaluated using a graded exercise test (GXT) with a verification bout (n = 35). Reliability between \"true\" V˙O2max and verification was determined. Correlations and regressions were performed.
RESULTS: Energy, carbohydrate, and micronutrient intake was lower than recommendations. Mean V˙O2max was 47.3 and 47.4 mL·kg-1·min-1 for GXT and verification, respectively. While correlations were apparent among dietary intake, V˙O2max, and body composition, percent fat-free mass (%FFM) predicted 36% of V˙O2max.
CONCLUSIONS: Collegiate
athletes are not meeting energy and carbohydrate recommendations and exceed fat recommendations. Vitamin D and magnesium were low in all sports, and iron and calcium were low in females. V˙O2max ranged from 35.6 to 63.0 mL·kg-1·min-1, with females below average and males meeting typical values for their designated sport. Assessing D1
athletes can provide guidance for sports dietitians, coaches, and strength and conditioning specialists to track and monitor nutrition in
athletes.
