Abstract：
To resolve problems in the dietary life of university athletes, education is essential to enable athletes to change their own dietary behavior. The purpose of this research was to verify the effectiveness of sports nutrition education based on self-determination theory (SDT). The participants were 36 male university rowers. A stratified randomized comparison test was conducted by student year (SDT group and control group). Sports nutrition education was held three times, via an Internet conferencing system. Furthermore, group work over social media was used for the SDT group. Four evaluations were carried out based on anthropometric measurements, a brief self-administered diet history questionnaire (BDHQ), sports nutrition knowledge test (SNK), and treatment self-regulation questionnaire (TSRQ). The results showed no differences between the two groups. However, for the intragroup factor, \"Protein\", a significant difference was evident in the self-determination theory group (50.0 ± 28.5, 78.6 ± 28.1, 81.0 ± 21.5, p < 0.000, units: %) and improved knowledge (p = 0.002, p = 0.002). And for the BDHQ, the self-determination theory group also showed significant differences and increased their intake of green and yellow vegetables, fruits, and dairy products (159.1 ± 74.2-126.7 ± 70.6, p = 0.009, 306.0 ± 196.2-195.2 ± 146.1, p = 0.020, 257.0 ± 147.0-183.3 ± 167.9, p = 0.040, units: g). In conclusion, sports nutrition education based on SDT improved dietary knowledge and increased food requirements for athletes.
摘要：
为了解决大学运动员饮食生活中的问题，教育对于运动员改变自己的饮食行为至关重要。本研究的目的是验证基于自决理论（SDT）的运动营养教育的有效性。参与者是36名男性大学赛艇运动员。按学生年（SDT组和对照组）进行分层随机比较测试。举办了3次运动营养教育,通过互联网会议系统。此外，SDT组使用社交媒体上的小组工作。根据人体测量进行了四次评估，一份简短的自我管理的饮食史问卷（BDHQ），运动营养知识测试（SNK），和治疗自我调节问卷（TSRQ）。结果显示两组之间没有差异。然而,对于群体内因子，“蛋白质”，在自决理论组(50.0±28.5,78.6±28.1,81.0±21.5,p<0.000,单位:%)和提高的知识(p=0.002,p=0.002)中,差异显著.对于BDHQ来说，自决理论小组也表现出显著差异，并增加了绿色和黄色蔬菜的摄入量，水果,乳制品（159.1±74.2-126.7±70.6，p=0.009，306.0±196.2-195.2±146.1，p=0.020，257.0±147.0-183.3±167.9，p=0.040，单位：g）。总之,基于SDT的运动营养教育提高了运动员的饮食知识，增加了对食物的需求。
