I have received a grant of 50,000 RMB from the Fundamental Research Funds for Central Universities to conduct this intervention project. The project will use an n-of-1 research design to explore the effects of medium-chain triglycerides on the athletic performance of long-distance runners. We seek approval to proceed with clinical registration prior to the formal implementation of the study.

N of 1 Trial 

研究目的:

在本项目中,我们将研究运动员在日常训练过程中摄入不同的膳食补充剂的效果,特别是探索哪些个体对中链甘油三酯(MCT)或碳水化合物(CHO)的反应更好。此外,我们还将研究长期摄入MCT对运动员运动表现和能量代谢的影响。此研究旨在为运动员提供个体化营养的可行参考和方案,填补国内外在基于n-of-1试验方法对运动员进行营养干预方面的空白。  

Objectives of Study:

In this project, we aim to study how different dietary supplements affect athletes during their regular training. Specifically, we will investigate which individuals respond better to medium-chain triglycerides (MCT) or carbohydrates (CHO) and examine the impact of long-term MCT consumption on athletic performance and energy metabolism. The goal is to provide feasible references and solutions for personalized nutrition in athletes, addressing a gap in the current research on nutritional interventions for athletes using the n-of-1 trial method.

药物成份或治疗方案详述:

膳食补充剂: (1)CHO溶液(每周3次):480g麦芽糊精+20g果糖+0.16g三氯蔗糖+2.92g柠檬酸+2.56g橙味精,加水至4L。 (2)MCT溶液(每周3次):210MCT+20g果糖+0.16g三氯蔗糖+2.92g柠檬酸+2.56g橙味精,加水至4L。 

Description for medicine or protocol of treatment in detail:

Dietary supplements: (1) CHO Solution (3 times per week):480 g of maltodextrin + 20 g of fructose + 0.16 g of sucralose + 2.92 g of citric acid + 2.56 g of orange flavoring, diluted with water to a total volume of 4 L. (2) MCT Solution (3 times per week):210 g of MCT + 20 g of fructose + 0.16 g of sucralose + 2.92 g of citric acid + 2.56 g of orange flavoring, diluted with water to a total volume of 4 L.

数据将由研究者现场采集,采用纸质记录的方式;随后纪记录在excel表格中。数据去除可识别受试者身份的关键信息(如姓名,学号等),且只有几位核心的研究者可以访问,访问者需要签署保密协议。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data will be collected on-site by the researchers using paper records and subsequently entered into an Excel spreadsheet. Identifiable information (e.g., names, student numbers) will be removed from the data, and only a few core researchers will have access to it. Accessors must sign a confidentiality agreement.
