Marosek, SEH, Antharam, V, and Dowlatshahi, K. Quantitative analysis of the acetic acid content in substances used by athletes for the possible prevention and alleviation of exercise-associated muscle cramps. J Strength Cond Res 34(6): 1539-1546, 2020-Athletes regularly consume commercially available food and sports shot products, carbohydrate beverages, and water to improve their physical exertion and to possibly prevent or relieve exercise-associated muscle cramps (EAMCs)-often experienced during practice, training, or competition. Acetic acid, a component of interest within these products, has been recognized for its potential role in cramp reduction. Acetic acid is postulated to mitigate cramping by decreasing alpha motor neuron activity through oropharyngeal stimulation and inhibitory neurotransmitter production, while aiding in the role acetylcholine plays in muscle contraction and relaxation. The purpose of this research is to analytically assess the most viable sources of acetic acid from substances that athletes ingest before or when experiencing these cramps. The range of samples investigated were based on their widespread use in the athletic world: dill and sweet pickle juices, yellow mustard, sweet relish, apple cider vinegar, Hot Shot, PJ Shot, PJ Sport, E-Lyte Sport, Powerade, Gatorade, Smartwater, and Propel (with electrolytes). As hypothesized, pH and enzymatic assay or spectroscopic analyses revealed that yellow mustard, sweet relish, all pickle juices, and the pickle juice products were composed of moderate amounts of acetic acid. Based on established studies resulting in EAMC relief, acetic acid consumption, and the appropriate serving size, the yellow mustard, PJ Shot, and all pickle juices would be the most practical and palatable sources of acetic acid for strength and conditioning professionals to recommend that athletes consume for the possible prevention or alleviation of muscle cramps.
马罗塞克、SEH、安东尼拉姆、V 和道拉塔希在运动员使用的物质中醋酸含量的定量分析，用于运动相关肌肉痉挛的预防和缓解。《力量与调节研究杂志》34（6）：1539-1546，2020 年——运动员经常食用市售食品和运动射击产品、碳水化合物饮料和水，以提高他们的身体活动能力，并可能预防或缓解运动相关肌肉痉挛（EAMC）——这些痉挛经常在练习、训练或比赛中发生。这些产品中的一种感兴趣的成分醋酸酸，已被认为在减少抽筋方面具有潜在作用。醋酸酸通过口腔刺激和抑制性神经递质的产生来减轻抽筋，同时帮助乙酰胆碱在肌肉收缩和松弛中发挥作用，这一假说被提出。本研究的目的是分析评估运动员在经历这些抽筋之前或期间摄入的物质中最可行的醋酸酸来源。调查的样本范围基于它们在运动界的广泛应用：莳萝和甜泡菜汁、黄芥末、甜泡菜、苹果醋、Hot Shot、PJ Shot、PJ Sport、E-Lyte Sport、Powerade、Gatorade、Smartwater 和 Propel（含电解质）。正如假设的那样，pH 值和酶分析或光谱分析表明，黄芥末、甜泡菜、所有泡菜汁和泡菜汁产品都含有适量的醋酸酸。根据导致 EAMC 缓解的既定研究、醋酸酸的消耗和适当的服务规模，黄芥末、PJ Shot 和所有泡菜汁将是力量和调节专业人员最实用和可口的醋酸酸来源，建议运动员食用，以预防或缓解肌肉痉挛。
