Research has found evidence that meeting physical activity (PA) recommendations (i.e., 60 min of daily moderate-to-vigorous PA) leads to a range of physical and psychosocial health and well-being benefits. 1 However, in Spain, 76.6% of children and youths between 11 and 17 years old are insufficiently physically active. 2 Since previous studies have shown that PA is a great benefit for health and wellbeing across the lifespan, 1 childhood is considered a very important period to develop a physically active lifestyle.
