摘要

本研究的目的是评估10名优秀女性冲浪运动员的饮食习惯。在比赛和训练期间完成的为期四天和五天的食物日记显示,能量摄入量(平均+/- SD)分别为9,468 kJ(+/- 2007)和8,397 kJ(+/- 1,831)。这一能量摄入水平低于冲浪所需的估计水平。女性冲浪者的碳水化合物摄入量未达到建议摄入量,90%的受试者未达到澳大利亚推荐摄入量。比赛和训练期间的碳水化合物(g和g/kg体重)和糖果(g)摄入量显著高于比赛期间(p < 0.05),蛋白质摄入量显著低于比赛期间(p < 0.05)。这些结果表明,虽然身体脂肪储存没有受到影响(平均22%),但在优秀的女性冲浪者中,自我报告的能量、碳水化合物和营养摄入量是微不足道的。问卷调查显示,90%的冲浪者在旅行时没有良好的营养习惯,这与缺乏营养实践知识有关。

Nutritional practices of elite female surfers during training and competition.

The aim of this study was to assess the dietary practices of 10 elite female surfers. Four- and five-day food diaries completed over competition and training periods demonstrated energy intakes (mean +/- SD) of 9,468 kJ (+/- 2,007) and 8,397 kJ (+/- 1,831), respectively. This level of energy intake was less than that estimated for the requirements of surfing. Female surfers' carbohydrate intakes failed to meet the recommendations, and suboptimal zinc intake was observed with 90% of subjects not meeting the Australian RDI. Comparisons between competition and training demonstrated that carbohydrate (g and g/kg body weight) and confectionary (g) intakes were significantly higher (p < .05) and protein intake was significantly lower (p < .05) during competition. These results show that although body fat stores were not compromised (mean 22%), self-reported energy, carbohydrate, and nutrient intakes were marginal in elite female surfers. Questionnaires revealed that 90% of surfers did not have good nutritional habits while traveling, which was compounded by a lack of knowledge of nutritional practices.
