To evaluate the impact of a video series versus online pamphlets/blog posts on Female Athlete Triad (Triad) and Relative Energy Deficiency in Sport (REDs) knowledge in high school female runners.
Runners from 10 US schools were cluster-randomised into groups to either watch videos or read pamphlets on Triad/REDs, nutrition, menstrual cycle, bone health and mental health. Changes in knowledge and interest were assessed using generalised estimating equations.
Forty-five runners were in the video intervention group (mean age=16.0) and 39 in the control (mean age=15.7). Both groups showed knowledge gains for all topics, except for mental health, where knowledge was already high. The intervention group's knowledge increase (means=75.7 and 93.3) was not significantly higher than the control's (means=77.9 and 93.6) (p=0.149). However, the intervention group had stronger scores on behavioural impact, information novelty and interest (means=3.77, 3.93 and 4.14) compared with the control's (means=3.36, 3.48 and 3.52) (p≤0.05, p≤0.05 and p≤0.001).
Both videos and pamphlets improved knowledge of Triad/REDs and female athlete science, however videos had a greater influence on athletes' engagement and behavioural intentions.
评估视频系列与在线宣传册/博客文章对高中女跑步运动员关于女性运动员三联征（三联征）和运动中的相对能量缺乏（REDs）知识的影响。
来自美国10所学校的跑步运动员被整群随机分组，分别观看关于三联征/REDs、营养、月经周期、骨骼健康和心理健康的视频或阅读宣传册。使用广义估计方程评估知识和兴趣的变化。
视频干预组有45名跑步运动员（平均年龄=16.0岁），对照组有39名（平均年龄=15.7岁）。两组在所有主题上的知识都有增加，但心理健康方面除外，该组知识水平原本就较高。干预组的知识增加量（均值=75.7和93.3）并不显著高于对照组（均值=77.9和93.6）（p=0.149）。然而，与对照组（均值=3.36、3.48和3.52）相比，干预组在行为影响、信息新颖性和兴趣方面得分更高（均值=3.77、3.93和4.14）（p≤0.05、p≤0.05和p≤0.001）。
视频和宣传册都提高了对三联征/REDs和女运动员科学知识的了解，但视频对运动员的参与度和行为意图有更大影响。
