About this study
Official title: Research and Development of New Sustainable Dietary and Nutritional Programs and Therapeutic Exercise for the Prevention of Metabolic and Musculoskeletal Disorders
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Behavioral: Nutritional InterventionBehavioural
Personalized dietary program based on sustainable Mediterranean diet principles, adapted to individual energy and nutritional requirements.
Conventional Strength TrainingOther
Traditional resistance training program including hypertrophy and strength-based exercises using guided machines and free weights.
Explosive Strength TrainingOther
High-intensity strength training focused on explosive movements using free weights.
Functional TrainingOther
Exercise program based on functional movements using alternative training materials.
Isoinertial TrainingOther
Resistance training program using isoinertial devices with an emphasis on eccentric load.
| Study group | Role | What they receive |
|---|---|---|
| Arm 1: Control Group | Active comparator | Nutritional intervention only (no structured exercise). Participants receive a personalized dietary intervention based on Mediterranean diet principles, without participation in a structured exercise program. Receives: Behavioral: Behavioral: Nutritional Intervention |
| Arm 2: Traditional resistance training (hypertrophy) + nutritional intervention | Experimental | Participants perform a hypertrophy-focused resistance training program combined with a personalized dietary intervention. Receives: Behavioral: Behavioral: Nutritional Intervention; Other: Conventional Strength Training |
| Arm 3: Explosive strength training + nutritional intervention | Experimental | Participants perform an explosive strength training program combined with a personalized dietary intervention. Receives: Behavioral: Behavioral: Nutritional Intervention; Other: Explosive Strength Training |
| Arm 4: Functional training + nutritional intervention | Experimental | Participants perform a functional training program using alternative materials combined with a personalized dietary intervention. Receives: Behavioral: Behavioral: Nutritional Intervention; Other: Functional Training |
| Arm 5: Isoinertial training + nutritional intervention | Experimental | Participants perform an isoinertial resistance training program combined with a personalized dietary intervention. Receives: Behavioral: Behavioral: Nutritional Intervention; Other: Isoinertial Training |
