Abstract

Background: Sports nutrition plays a crucial role in providing the fuel to meet the energy demands of athletes' training programmes, enhancing adaptations associated with training, and ensuring rapid recovery between workouts. However, evidence suggests that the dietary habits of many athletes are unsatisfactory when compared to sport-specific nutrition recommendations. This discrepancy is mainly due to a lack of up-to-date, evidence-based nutritional knowledge. Hence, this parallel-group, randomized controlled clinical trial aims to evaluate the effectiveness of a 16-week evidence-based, culturally appropriate, personalized sports nutrition intervention on the sports nutrition knowledge and nutritional status of track and field athletes in Sri Lanka, in comparison to a control group that does not receive this intervention.

Methods: Elite and highly trained track and field athletes, competing at the national level and/or representing Sri Lanka in international competitions, will be randomly allocated to either the intervention group (IG) (n = 15) or the control group (CG) (n = 15). Participants in the IG will receive an evidence-based, culturally acceptable, personalized sports nutrition intervention from the principal investigator through one-to-one consultations at three-time points (zeroth, fourth, and eighth weeks), while participants in the CG will be followed up throughout the period without receiving the intervention. The primary outcome measure is the number of participants who achieve at least a 10% increase in mean sports nutrition knowledge (SNK) score at the end of the 16^th week, compared to the CG. Secondary outcomes include nutrition status and sports performance-related measures at the beginning and end of the intervention.

Discussion: While the primary objective is to enhance SNK, it is anticipated that improvements in nutritional status and overall health may significantly impact sports performance and career longevity of the athletes.

背景：运动营养在提供燃料以满足运动员训练计划的能量需求、增强与训练相关的适应性以及确保运动间歇期的快速恢复方面发挥着至关重要的作用。然而，有证据表明，与针对特定运动的营养建议相比，许多运动员的饮食习惯并不令人满意。造成这种差异的主要原因是缺乏最新的循证营养知识。因此，这项平行分组随机对照临床试验旨在评估为期 16 周的循证、文化适宜的个性化运动营养干预对斯里兰卡田径运动员运动营养知识和营养状况的影响，并与未接受干预的对照组进行对比：方法：训练有素的田径精英运动员将被随机分配到干预组（IG）（n = 15）或对照组（CG）（n = 15），他们将参加国家级比赛和/或代表斯里兰卡参加国际比赛。干预组的参与者将在三个时间点（第 4 周、第 4 周和第 8 周）通过一对一咨询接受由主要研究人员提供的循证、文化上可接受的个性化运动营养干预，而对照组的参与者将在没有接受干预的情况下接受全程跟踪。主要结果指标是，在第 16 周结束时，与 CG 相比，运动营养知识（SNK）平均得分至少提高 10%的参与者人数。次要结果包括干预开始和结束时的营养状况和运动表现相关指标：讨论：虽然主要目标是提高营养知识，但预计营养状况和整体健康的改善可能会显著影响运动员的运动表现和职业寿命：斯里兰卡临床试验注册中心，SLCTR/2024/013。注册日期：2024 年 4 月 10 日。通用试验编号（UTN）：U1111-1304-8890。

期刊介绍： Trials is an open access, peer-reviewed, online journal that will encompass all aspects of the performance and findings of randomized controlled trials. Trials will experiment with, and then refine, innovative approaches to improving communication about trials. We are keen to move beyond publishing traditional trial results articles (although these will be included). We believe this represents an exciting opportunity to advance the science and reporting of trials. Prior to 2006, Trials was published as Current Controlled Trials in Cardiovascular Medicine (CCTCVM). All published CCTCVM articles are available via the Trials website and citations to CCTCVM article URLs will continue to be supported.
