摘要
通过对湛江师院网球专项学生的膳食营养调查,了解网球专项学生膳食营养状况及其存在的问题,为其合理膳食结构提供科学的指导依据.采用膳食调查记录法,对100名网球专项学生每天膳食摄入量进行记录,然后从食物结构、三大产能营养素的食物来源、营养素摄入状况进行分析.网球专项男、女生食物结构不合理,畜禽肉类、豆类、蛋类、鱼虾类普遍摄入不足.三大产能营养素的食物来源以植物性食物为主,肉食性食物和豆类摄入量较少.男、女生总能量均摄入不足,仅为RNIs标准的87.1%.维生素B1、B2、C均达到RNIs标准供给量,但维生素A摄入严重不足,仅为RNIs标准的47.1%.铁、锌、硒、钙等4种无机盐都低于RNIs推荐供给量,尤其钙为摄入严重不足.湛江师院网球专项学生与他们所从事的运动所需的营养标准有着一定差距,为保证网球队员的运动能力及提高运动成绩,建议开设营养知识讲座及为运动员开设专门的营养配餐.
