Abstract

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.

摘要

本研究的目的是评估10名精英女性冲浪运动员的饮食习惯。在比赛和训练期间完成的四日和五日饮食日记显示,能量摄入量(均值±标准差)分别为9468千焦(±2007)和8397千焦(±1831)。这一能量摄入水平低于根据冲浪运动需求估算的量。女性冲浪运动员的碳水化合物摄入量未达到建议值,且观察到锌摄入量不理想,90%的受试者未达到澳大利亚推荐膳食摄入量。比赛与训练期间的比较表明,比赛期间碳水化合物(克及克/千克体重)和糖果(克)摄入量显著更高(p<0.05),而蛋白质摄入量显著更低(p<0.05)。这些结果表明,尽管身体脂肪储备未受影响(平均22%),但精英女性冲浪运动员自我报告的能量、碳水化合物和营养素摄入量处于边缘水平。问卷调查显示,90%的冲浪运动员在旅行时没有良好的营养习惯,而对营养做法缺乏了解使情况更加复杂。
