Protocol for a Natural-Based Intervention to Promote Quality of Life and Healthy Habits on Children and Adolescents.

In current society, physical activity practices show a decreasing trend, together with a low perception of life quality.

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
