Energy Deficit Syndrome (RED-S) is the impairment of physiological functioning caused by relative energy deficiency and includes impaired metabolic rate, menstrual, endocrine, hematological, immunological, gastrointestinal, bone, psychological, developmental and cardiovascular function. Eighty-seven percent of athletes show at least one symptom related to RED-S, with a higher prevalence in women. Treatment of RED-S preferably involves a multidisciplinary team of health professionals to address the complex interaction of nutrition, training, body image and performance. The main objective is to prevent energy deficit syndrome in female athletes in the province of Alicante through different training and diet protocols using a virtual platform. A 12-week single-blind randomized clinical trial with an intervention period and a control period (RCT) is proposed. The sports federations of the most representative practices in the province of Alicante will be selected by randomized sampling. The female athletes will be randomly divided into 4 groups (control group; control group with free use of the virtual platform; intervention group with Mediterranean diet and physical exercise planning; intervention group with red fruits and physical exercise planning).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | No Intervention | Will receive basic recommendations from the World Health Organization on healthy eating and physical activity. | |
| Control group with free use of the virtual platform | Placebo Comparator | The athletes, in addition to the recommendations indicated in the previous point, will have access to the virtual platform designed to voluntarily record the parameters they consider appropriate. |
|
| Intervention group with Mediterranean diet and physical exercise planning | Active Comparator | They will receive nutritional plans adapted to their energy expenditure and based on Mediterranean diet. The physical exercise intervention will be based on 3 weekly sessions of 50 minutes of combined resistance and strength, deferred. |
|
| Intervention group with red berries and physical exercise planning | Active Comparator | They will also receive personalized nutritional plans with a diet rich in antioxidants obtained from red berries and the same physical exercise intervention as in the Mediterranean diet intervention group. |

| Perception of quality of life | Using a Quality of Life Questionnaire (SF36). Quality of Life Questionnaire is a comprehensive questionnaire that covers various attributes of an individuals life. It covers a variety of demographic questions to get better quality data and information before analyzing the quality of life of an individual.The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. | 12 weeks |
| Mood state | Profile of Mood State Questionnaire (POMS). The POMS questionnaire assesses six mood subscales: tension-anxiety, depression, anger-hostility, vigor, fatigue, and confusion. High vigor scores reflect a good mood or emotion, and low scores in the other subscales reflect a good mood or emotion. | 12 weeks |
| Eating behavior | Eating Behavior Questionnaire (EAT-26). It is used to identify the presence of "eating disorder risk" based on attitudes, feelings and behaviours related to eating. There are 26 self-report questions assessing general eating behaviour and five additional questions assessing risky behaviours. The total score (between 0 and 78) provides an overall risk score, where higher scores indicating greater risk of an eating disorder. Total scores 20 or above are considered to be in the clinical range. | 12 weeks |
