About this trial
The aims of this school-based cycling intervention called "ENERGY Commuting to school" (ENERGYCO) will be divided into two phases: Phase I will aim: 1) to design, test, and validate predictive equations for the objective quantification of the energy expenditure related to different modes of commuting to school (i.e., walking, cycling, motorized-vehicle); and 2) to quantify the energy expenditure of each mode of commuting to school using indirect calorimetry in adolescents; and Phase II will aim to evaluate the effect of a school-based cycling intervention on different health-related outcomes, such as energy expenditure, resting metabolic rate, basal metabolism, physical activity levels, body composition, muscle strength, cardiorespiratory fitness, blood pressure, physical literacy, motor competence, and psychosocial outcomes on Spanish adolescents.

Treatments tested in this trial
Cycling Intervention Group
BehavioralA eight-weeks school-based cycling program. The school-based cycling intervention consists of 2 Bikeability sessions of 60 min at Physical Education lessons in school, and will focus on promote biking through theory and practice lessons about cycle training skills including on-road training. In addition, participants will receive encouragement strategies, one for each week of the intervention, for cycling to and from school during eight weeks.
