Screening Program of Relative Energy Deficiency in Sports in College Athletes

Study Overview
=================
Brief Summary
-----------------
The investigators hope that through this study will know the prevalence of Relative Energy Deficiency in Sports (RED-S) and its impact on sports injuries, performance and illness among college athletes in Taiwan. And also to find an appropriate diagnosis and intervention model to take care of athletes' health and improve sports performance Taiwan's athletes in the future.

Detailed Description
-----------------
This project is divided into 3 steps for a period of two years. The first step (0-6 months) is expected to recruit a total of 100 college athletes from Taekwondo, judo, rhythmic gymnastics, and long-distance runners for Relative Energy Deficiency in Sports (RED-S) screening. The second step (7-18 months) is targeted at athletes who have been screened for potential RED-S risk (the number is tentatively 30) in the first step. The diagnostic tools refer to the clinical assessment of Relative Energy Deficiency in Sport Clinical Assessment Tool (RED-S CAT). The third stage (19-21 months) is intervention programs targeted at the athletes who are diagnosed with RED-S (the number is tentatively 20) at 2nd step. The intervention programs consist of nutrition monitoring and diet intervention. The investigators hope that through this study will know the prevalence of RED-S and its impact on sports injuries, performance and illness among college athletes in Taiwan. And also to find an appropriate diagnosis and intervention model to take care of athletes' health and improve sports performance Taiwan's athletes in the future.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluate the phenomenon of low Energy Availability (low EA) among college athletes in Taiwan. | Stage I in this study will recruit college athletes (n=100) to evaluation the subjects' energy availability (EA), calculated as energy intake (EI) minus exercise energy expenditure (EEE), normalized to fat free mass (FFM) per day (unit: kcal/kg·FFM/day). Participants' Energy Availability (EA) value lower than 30 kcal/kg·FFM/day as the status with low Energy Availability (low EA). | 0-6 months | 
| Stratification the risk category of RED-S of the college athletes by using the Relative Energy Deficiency in Sport Clinical Assessment Tool (RED-S CAT). | Stage II in this study will recruit the low Energy Availability (low EA) college athletes in Stage I (n=60), evaluate their risk category of RED-S by using Relative Energy Deficiency in Sport Clinical Assessment Tool (RED-S CAT). | 7-18 months | 
| Evaluate the improvement of energy availability (EA) after intervention with nutrition education. | Stage III in this study will recruit the low Energy Availability (low EA) college athletes in Stage II (n=40) with high or moderate risk. Evaluate the improvement of energy availability (EA) after intervention with nutrition education. Energy availability (EA), calculated as energy intake (EI) minus exercise energy expenditure (EEE), normalized to fat free mass (FFM) per day (unit: kcal/kg·FFM/day). | 19-21 months |
