Effective nutritional intervention can help reduce the risk of nutritional problems and improve athletic performance in adolescents. The five A's (assess, advise, agree, assist, and arrange) model is widely used as the theoretical framework for advice on nutrition, smoking, drinking, and physical activity and it recommends that practitioners in primary health care promote behavior change to facilitate positive outcomes. This model has also been useful in understanding the underlying processes of behavior change. This study aimed to develop both a novel evidence-based nutritional intervention protocol, rooted in sound nutritional theory, and a customizable nutritional intervention program to support sustainable healthy eating, enhance nutrient intake, and improve athletic performance in adolescent athletes.
In this study, we adapted the 5 A's behavioral change model and motivational interview to develop a theoretical framework to help adolescent athletes change their behavior and achieve their goals.
During each step of the 5 A's protocol, a customized nutritional intervention protocol was developed by nutrition experts for each of adolescent athletes. Each plan was developed to improve the eating habits of adolescent athletes through group education and counseling. All nutritional counseling sessions were designed to enable participants to apply nutritional knowledge and practical action plans to their training and competition conditions to enable each of them to achieve individual athletic goals and facilitate self-management.
A theoretical and evidence-based nutritional intervention protocol was developed to identify and address obstacles to healthy dietary habits in adolescent athletes. This could be used as the basis for further studies aimed at improving nutrient intake and athletic performance in adolescent athletes.
有效的营养干预有助于降低青少年出现营养问题的风险并提高其运动表现。“五个A”（评估、建议、协商、协助和安排）模型被广泛用作营养、吸烟、饮酒及体育活动方面建议的理论框架，它建议初级卫生保健从业者促进行为改变以促成积极结果。该模型在理解行为改变的潜在过程方面也很有用。本研究旨在制定一种基于可靠营养理论的新型循证营养干预方案，以及一个可定制的营养干预计划，以支持青少年运动员保持可持续的健康饮食、增加营养摄入并提高运动表现。
在本研究中，我们采用“五个A”行为改变模型和动机性访谈来构建一个理论框架，以帮助青少年运动员改变行为并实现其目标。
在“五个A”方案的每个步骤中，营养专家为每位青少年运动员制定了定制的营养干预方案。每个计划旨在通过集体教育和咨询来改善青少年运动员的饮食习惯。所有营养咨询课程的设计目的都是让参与者将营养知识和实际行动计划应用于他们的训练和比赛情况，以使他们每个人都能实现个人运动目标并促进自我管理。
制定了一种基于理论和证据的营养干预方案，以识别和解决青少年运动员健康饮食习惯的障碍。这可作为进一步研究的基础，旨在提高青少年运动员的营养摄入和运动表现。
