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.

Study Arms (5)

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.

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.

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.

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.

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.

Behavioral: Behavioral: Nutritional Intervention; Other: Isoinertial Training

Interventions

Behavioral: Nutritional Intervention BEHAVIORAL

Personalized dietary program based on sustainable Mediterranean diet principles, adapted to individual energy and nutritional requirements.

Arm 1: Control Group; Arm 2: Traditional resistance training (hypertrophy) + nutritional intervention; Arm 3: Explosive strength training + nutritional intervention; Arm 4: Functional training + nutritional intervention; Arm 5: Isoinertial training + nutritional intervention

Conventional Strength Training OTHER

Traditional resistance training program including hypertrophy and strength-based exercises using guided machines and free weights.
