概括

耐力运动员应该意识到碳水化合物 (CHO) 凝可能含有比标签更少的能量. 一个品牌,Spring Energy,显示了显著的能量和CHO差异,影响了性能和临床考虑.

科学领域:

运动营养运动营养
营养生物化学营养生物化学
运动生理学运动生理学

背景情况:

碳水化合物 (CHO) 凝被耐力运动员广泛使用,以提高比赛中的表现.
已发表的研究和事报告表明,商业CHO凝中存在潜在的能量和宏观营养素缺乏.
准确的营养含量对于运动员来说至关重要,以满足能量需求并避免不良影响.

研究的目的:

分析各种品牌商用CHO凝的能量和碳水化合物含量.
将实际的营养含量与产品标签上提供的信息进行比较.
确定任何差异,并评估它们对运动员的潜在影响.

主要方法:

来自八个不同品牌的CHO凝的内容分析:Gu Energy,蜂蜜刺,Hüma,Maurten,Näak,精密燃料,体育科学和春季能源.
测量能量和CHO含量与标签上的营养信息进行比较.
布兰德-阿尔特曼分析,以评估系统偏见和共识的极限.
对表现出差异的多个特定产品批发的后续分析.

主要成果:

平均而言,CHO凝的能量含量远低于标签上所述的能量 (p = .047,大效果).
与标签相比,碳水化合物 (CHO) 含量没有发现显著差异 (p = .219,中等效果).
春季能源产品显示大量报告不足,大约比标签少了71%的能量和72%的CHO,超出了协议限制.

结论:

商用CHO凝,平均而言,提供的能量比标签上标明的要少.
在一些产品中观察到显著的差异,特别是能量含量,特别是春节能源.
这些发现对体育表现,临床营养和监管监督具有重要意义.

Introduction to Carbohydrates

Introduction to Carbohydrates

Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...
