Brief summary
The SUSTAINA study aims to evaluate the effects of sustainable dietary programs combined with individualized therapeutic exercise on metabolic health, body composition, and musculoskeletal function in young athletes. Participants will be randomly assigned to different intervention groups receiving tailored exercise training and nutritional guidance based on Mediterranean diet principles. The study will assess physiological, anthropometric, and functional outcomes to identify effective strategies for preventing metabolic and musculoskeletal disorders.
Detailed description
This study is a randomized controlled trial designed to investigate the impact of combined dietary and exercise interventions on health outcomes in young athletes. Participants will be allocated into different groups, including a control group and intervention groups receiving structured therapeutic exercise programs and personalized nutritional strategies based on sustainable Mediterranean diet principles. Measurements will include body composition, metabolic parameters, physical performance, and musculoskeletal function. The intervention is expected to provide evidence-based strategies to prevent metabolic and musculoskeletal disorders in physically active populations.
Interventions
BEHAVIORALBehavioral: Nutritional Intervention
Personalized dietary program based on sustainable Mediterranean diet principles, adapted to individual energy and nutritional requirements.
Traditional resistance training program including hypertrophy and strength-based exercises using guided machines and free weights.
OTHERExplosive Strength Training
High-intensity strength training focused on explosive movements using free weights.
OTHERFunctional Training
Exercise program based on functional movements using alternative training materials.
OTHERIsoinertial Training
Resistance training program using isoinertial devices with an emphasis on eccentric load.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in blood glucose levels | Baseline to 9 months | Measurement of blood glucose levels using a portable biochemical analyzer. |
| Change in triglyceride levels | Baseline to 9 months | Assessment of triglyceride levels using a portable biochemical analyzer. |
| Change in bone mineral content | Baseline to 9 months | Assessment of bone mineral content using dual-energy X-ray absorptiometry (DXA). |
| Change in total cholesterol levels | Baseline to 9 months | Assessment of total cholesterol levels using a portable biochemical analyzer. |
| Change in handgrip strength | Baseline and 9 months | Assessment of upper body isometric strength using a handgrip dynamometer. Measured in kilograms (kg) |
| Change in lower body strength (countermovement jump height) | Baseline and 9 months | Assessment of lower body strength using countermovement jump (CMJ) height measured with a contact platform (cm). |
| Change in sprint performance | Baseline and 9 months | Assessment of sprint performance using 10-30 meter sprint tests measured with photocell timing systems. Measured in seconds (s) |
| Change in endurance capacity (Yo-Yo Intermittent Recovery Test Level 1) | Baseline and 9 months | Assessment of endurance capacity using the Yo-Yo Intermittent Recovery Test Level 1, expressed as total distance covered (meters). |
| Change in functional movement (Functional Movement Screen score) | Baseline and 9 months | Assessment of functional movement using the Functional Movement Screen (FMS), scored from 0 to 21 points, where higher scores indicate better movement quality and lower injury risk. |

| Change in hydration status (urine color scale) | Baseline and 9 months | Assessment of hydration status using a validated urine color scale ranging from 1 to 8, where lower values indicate better hydration status and higher values indicate dehydration. |
| Change in blood pressure | Baseline and 9 months | Measurement of systolic and diastolic blood pressure using a digital sphygmomanometer. |
| Change in basal metabolic rate | Baseline and 9 months | Assessment of basal metabolic rate using indirect calorimetry. |
