Clinical trials

This prospective observational study evaluates the effect of bariatric surgery on mental health and hair cortisol in patients with morbid obesity over a 3-year follow-up. Assessments will be performed before surgery and at 1 month, 1 year, 2 years, and 3 years to analyze psychological changes, weight changes, and the need for psychological support.

The goal of this clinical trial is to learn if a low to moderate load power training program is feasible and effective for improving fitness and quality of life of people with prostate cancer under androgen suppression therapy and bone or lymph node metastasis. The main questions it aims to answer are: * Does a low to moderate load power training program improve quality of life in people with metastatic prostate cancer under androgen deprivation therapy? * Does a low to moderate load power training program improve power, strength, endurance, and balance in people with metastatic prostate cancer under androgen deprivation therapy? Researchers will compare the exercise program with routine care to see if power training works to improve common physical side effects of androgen suppression therapy in patients with metastatic prostate cancer. Participants will: * Participate in a supervised exercise program twice a week for 6 months or maintain routine care. * Perform fitness tests and questionnaires about quality of life and mental health. * Those who take part in the exercise program will also perform semi-structured in-depth interviews after the end of the program.

This is an observational study aiming to assess the nutritional knowledge, dietary habits, supplement use, body composition, and physiological profiles of HYROX athletes. The main objective is to describe and evaluate the nutritional, anthropometric, and performance-related characteristics of these athletes to better understand factors influencing race performance. The main question it seeks to answer is: What are the nutritional, kinanthropometric, and physiological profiles of HYROX athletes, and how are dietary practices, supplement use, and body composition associated with their performance?

Disability involves limitations that affect mobility and the ability to perform daily activities and achieve competitive goals. It is expected that disability has a significant impact on body composition, including reductions in lean mass and bone mineral content, and increases in fat mass and its distribution. Additionally, the assessment of food and dietary supplement intake among athletes with disabilities remains poorly described, despite its relevance in both sports and health contexts due to the potential benefits of individualized nutritional strategies. This research project, entitled Anthropometric, Dietary, Exercise, and Supplementation Profile in Athletes with Disabilities (PADES), aims to describe the anthropometric characteristics, physical exercise practices, and food and supplement intake in Spanish athletes with disabilities. The study seeks to address the current lack of standardized anthropometric data and the limited information on dietary and supplementation patterns in this population, which hinders a comprehensive understanding of the physiological, nutritional, and biomechanical aspects essential for their health and athletic performance. A cross-sectional, descriptive-correlational study will be conducted in Spanish athletes with disabilities recruited through the Spanish Federation of Sports for People with Physical Disabilities (FEDDF), the Spanish Federation of Sports for the Blind (FEDC), and the Spanish Federation of Sports for the Deaf (FEDS).

The NutriEvalUA program is an observational study aiming to assess the nutritional status, body composition, hydration, physical activity, and health indicators in university athletes. The main objective is to describe and evaluate dietary habits, supplement use, physical condition, and related risk factors to improve health and sports performance in this population. The main question it aims to answer is: What is the nutritional, body composition, hydration, physical activity, and general health profile of university athletes at the University of Alicante, and which factors are associated with potential risks to their performance and well-being?

The goal of this observational study is to determine if physical activity and the adherence to a Mediterranean diet have a relationship with body composition, growth, and maturation status in youth triathletes. The main question it aims to answer is: • Is body composition (fat and muscle) determined primarily by growth and biological maturation or by physical activity and the Mediterranean diet in youth triathletes? Participants already have been evaluated in body composition, mediterranean diet adherence and practical of physical activity during 3 years.
