The tool kits of bibliometrics and science mapping provide a standard methodology to map the knowledge base of specific fields of science. The aim of the present research is the analysis of the recent international trends of sport nutrition science, as well as the primary identification of the research topics and results of sport nutrition science via enhanced bibliometric methods for the 2000-2018 time period.
Altogether, 3889 publications were included in this study. We identified the most relevant sport nutrition topics by running a community detection algorithm on the proximity network constructed via network text analysis. The key issues and key concepts of sport nutrition topics as well as their relations were evaluated via network analysis. Besides, we carried a chronological analysis of topics out and a scientometric evaluative analysis was also created.
We identified the four main basic groups from which the 18 most characteristics topics were analyzed. The 18 topics are the following: 'soccer and physiology', 'carbohydrate metabolism', 'muscle physiology: alkalosis and acidosis', 'muscle mass gain and dietary supplementation', 'fluid balance and hydration', 'dietary intake and nutrition knowledge', 'determination of energy need of athletes', 'bone health and female athlete triad', 'hydration strategy', 'body weight management', 'nutritional strategies and human skeletal muscle', 'dietary supplementation of nitrates', 'oxidative stress and dietary supplement use', 'dietary supplement use and doping', 'oxidative stress and inflammation and dietary antioxidants', 'exercise adaptation and nutritional strategies', 'gut microbiota', 'celiac disease'. Regarding the size of the topic, researches on sport nutrition science have put the focus on the following three groups: 'muscle mass gain and dietary supplementation', 'carbohydrate metabolism', 'oxidative stress and dietary supplement use'. The greatest scientific impact can be ascribed to the following topics: 'nutritional strategies and human skeletal muscle', 'dietary supplementation of nitrates', 'body weight management', and 'gut microbiota'.
Scientific output on sport nutrition has continuously been rising between 2000 and 2018. The ratio of topics related to sport nutrition but predominantly connected to basic research has decreased significantly within all publications. The results of this study confirm the role of science mapping in the identification of specific research topics and primary research directions in the field of sport nutrition science.
文献计量学和科学绘图工具包为绘制特定科学领域的知识库提供了标准方法。本研究的目的是分析运动营养科学的近期国际趋势，并通过增强的文献计量学方法，对 2000-2018 年期间的运动营养科学的主要研究主题和结果进行初步识别。
本研究共纳入 3889 篇文献。我们通过在通过网络文本分析构建的接近网络上运行社区检测算法，确定了最相关的运动营养主题。通过网络分析评估运动营养主题的关键问题和关键概念及其关系。此外，我们还进行了主题的时间序列分析，并创建了科学计量评估分析。
我们从四个主要基本组中确定了 18 个最具特色的主题进行分析。这 18 个主题如下：“足球与生理学”、“碳水化合物代谢”、“肌肉生理学：碱中毒和酸中毒”、“肌肉质量增加和饮食补充”、“液体平衡和水合作用”、“饮食摄入和营养知识”、“运动员能量需求的确定”、“骨健康和女性运动员三联征”、“水合作用策略”、“体重管理”、“营养策略和人类骨骼肌”、“硝酸盐饮食补充”、“氧化应激和膳食补充剂使用”、“饮食补充剂使用和兴奋剂”、“氧化应激和炎症与膳食抗氧化剂”、“运动适应和营养策略”、“肠道微生物组”、“乳糜泻”。关于主题的规模，运动营养科学的研究主要集中在以下三个组：“肌肉质量增加和饮食补充”、“碳水化合物代谢”、“氧化应激和膳食补充剂使用”。最大的科学影响力可归因于以下主题：“营养策略和人类骨骼肌”、“硝酸盐饮食补充”、“体重管理”和“肠道微生物组”。
2000 年至 2018 年间，运动营养方面的科学产出不断增加。在所有出版物中，与运动营养相关但主要与基础研究相关的主题比例显著下降。本研究的结果证实了科学绘图在识别运动营养科学领域特定研究主题和主要研究方向中的作用。
