The PACO RCT Study

Study Overview
=================
Brief Summary
-----------------
The aim of this school-based cycling intervention called Cycling and Walk to School (PACO, for its Spanish acronym) will be to examine their effects on adolescent's cycling to and from school and physical activity (PA). This study will also examine the effects of this intervention in several active commuting to and from school (ACS)-related variables belonging to Self-Determination Theory (SDT) and Social-Ecological Model (SEM).

Detailed Description
-----------------
This study will also examine the effects of this intervention in several active commuting to and from school (ACS)-related variables belonging to SDT and SEM. In this randomized controlled trial will participate 360 adolescents, belonging to six secondary schools (three experimental and three control) from three Spanish cities. The intervention will be conducted by both the research staff and the physical education (PE) teacher through four cycling sessions (one per week). PA levels will be measured by accelerometers, and the other study variables by using self-reported scales, before and after the intervention programme. The primary outcomes will be: cycling to school, ACS, and PA levels. The secondary outcomes will be: SDT (Self-Determination Theory) -related variables in ACS and individual, interpersonal, communittal and environmental variables related to ACS belonging to SEM (Social-Ecological Model). The findings of this study will provide a comprehensive understanding of the effects of this short-term school-based intervention on cycling to school and PA levels of Spanish adolescents.
