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.
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.
