Natural-Based Multicomponent Intervention to Promote Quality of Life and Healthy Habits on Children and Adolescents: Protocol for a Randomized Controlled Trial

In current society, physical activity practices show a decreasing trend, together with a low perception of life quality. In addition, urban overcrowding has led to disconnection from the natural environment, causing the benefits that this context offers to be lost, especially for children and adolescents. Physical literacy is an approach to physical activity that encompasses more than just individual physical skills. It emphasises the importance of performing physical activity on a regular basis as part of daily life, encompassing bodily expression and understanding, as well as self-confidence and motivation, making it a factor that contributes to quality of life. Although research shows a correlation between physical literacy and life satisfaction, there is no research on other variables, such as the impact of green spaces in this correlation. This study aimed to present the rationale and methods of a randomized controlled trial in green spaces for children and adolescents aged 8 to 18 to evaluate the efficacy of a nature-based intervention designed to promote healthy habits through physical literacy and quality of life through life satisfaction. The statistical techniques applied will include a comprehensive method encompassing sociodemographic information, physical activity levels, perceptions of physical literacy, and life satisfaction. The camp shifts were randomly distributed, with half in the control group and the other half in the experimental group . Two measures of physical literacy and life satisfaction were measured: one at the beginning of the camp and one on the day of completion. The intervention included 24 sessions of adventure activities carried out in a natural environment, and the values obtained for both variables were collected using two questionnaires validated for these age groups. This intervention is expected to improve levels of physical literacy and perceived life satisfaction by providing valuable
