Methodologies study and preparation of the intervention The program was developed by 4 teachers, 7 graduate students, 1 nutritionist, 2 graduate Nutrition students, and 1 cardiologist, and participated in weekly meetings where methodologies and intervention sessions were prepared and tested. During this test period, activities that would promote greater adherence of students were listed. Additionally, participants randomly used a heart rate monitor (Polar Team2 Pro, Polar, Finland) and an accelerometer (Actigraph, GT3X model), in order to record activities that promoted more significant increases in heart rate and in moderate and vigorous PA intensities.
