职业橄球运动员经常摄入不足的宏观营养素,特别是碳水化合物,低于最佳表现的建议水平. 这项研究强调了需要有针对性的饮食教育和监测,以改善营养和支持球员恢复.
科学领域:
- 运动营养 运动营养
- 运动生理学 运动生理学
- 饮食评估 饮食评估
背景情况:
- 橄球联盟是一项高度接触的运动,具有重要的训练和游戏负载.
- 以前的研究表明,橄球运动员的宏观营养素 (碳水化合物,蛋白质,脂肪) 摄入量不足.
- 最佳营养对于职业运动员的表现和恢复至关重要.
研究的目的:
- 描述职业橄球运动员在赛季开始时在Zebre橄球俱乐部摄取的宏观营养素.
- 将球员的宏观营养素摄入量与国际体育营养建议进行比较.
- 为了确定影响球员表现的潜在营养差距.
主要方法:
- 这是一项涉及34名职业男橄球运动员的横截面研究.
- 使用了自己开发的问卷,食物频率问卷和3天的食物记录.
- 使用ISAK标准化的技术收集了人类测量测量结果.
主要成果:
- 平均体脂百分比超过了国际推 (8-17%).
- 90%的球员消耗的碳水化合物低于推水平 (2.7g/kgBW与5.0-8.0g/kgBW).
- 在比赛日,近30%的球员摄入的蛋白质量低于推量 (1.7g/kgBW与1.5-2.0g/kgBW).
结论:
- 结果为斑马橄球俱乐部提供了洞察力,以使球员的营养与工作负载需求保持一致.
- 强调需要准确的饮食教育,摄入量监测和个性化的营养策略.
