Abstract
Background: It is not known whether an intervention made mandatory as a physical education (PE) class assignment and aimed
at promoting physical activity (PA) in adolescents can create a healthy walking habit, which would allow further improvements

Objective: The aims of this study were to (1) investigate whether, after a period of using a step tracker mobile app made
mandatory and promoted as a PE class assignment, adolescents continue to use it when its use is no longer mandatory and

of the app is mandatory and promoted and when it is neither mandatory nor promoted; and (3) analyze whether the covariates
maturity status, gender, and specific app used can have an influence.
Methods: A total of 357 students in compulsory secondary education (age: mean 13.92, SD 1.91 y) partic...
