%X Introduction: The aim of this study was to test the feasibility, acceptability, and effectiveness
of a physically active learning (PAL) intervention (ACTIVE CLASS pilot
study) to improve physical health and cognitive and academic performance, increase
physical activity (PA) levels, and reduce sedentary time (ST) in adolescents,
and to analyze the distribution of activity intensity during a PAL lesson and assess
differences with physical education lessons. Methods: A quasi-experimental
study was conducted including 77 students aged 12–14 yr from two Spanish secondary
schools. The ACTIVE CLASS pilot program consisted of integrating a
weekly PAL lesson intomathematics lessons for 4 wk. Changes in body composition
(bodymass index andwaist circumference), physical fitness (cardiorespiratory
andmuscular fitness), executive functions (inhibition, workingmemory, and cognitive
flexibility), and mathematical fluencyweremeasured. Accelerometer-based ST
and PA were measured in the intervention group. The feasibility and acceptability
of the intervention were assessed using self-reported questionnaires for teachers
and students. Repeated-measures analyses of variance were used to test the effects
of the intervention. Results: There were no significant improvements in body
composition, fitness, and cognitive and academic performance when comparing
the intervention and control groups. The inclusion of the PAL intervention significantly
increased average PA levels and reduced ST during the school day, and
no significant differences were found in accelerometer-based variables between
physical education and PAL lessons. In fact, PAL lessons could provide up to
17min ofmoderate/vigorous PA. In addition, teachers and students reported good
feasibility and acceptability of the PAL intervention. Conclusion: The findings support
further research with a longer-termintervention and a larger sample size to determine
the true potential of PAL for adolescents’ physical health, cognition, and
academic performance.
