Resumo
Background & purpose: Previous studies have indicated that Physical Education classes do
not provide sufficient time in moderate to vigorous intensity physical activity (MVPA)
according to recommendations by international organizations. Thus, this study aimed to
compare the intensity achieved using different strategies in Physical Education classes, and
secondarily to investigate the fun, motivation, and engagement of students. Methods: In total,
52 students were included, 23 girls and 29 boys. A recreational strategy and an additional
circuit/HIIT class were applied and compared with a traditional class. All classes were
structured with the content of games and activities. The intensity was monitored using a
portable heart rate monitor and the subjective perception of exertion (RPE) was recorded. For
comparisons between each class strategy, the Kruskal-Wallis test and Dunn's test were applied
to locate significant differences (P<0.05), as well as for comparisons of heart rate (HR) and
RPE. Qualitative data are presented as percentages of interview responses. Results: The
circuit/HIIT and recreational strategy showed significant superiority (P<0.01) in the proportions
of time in MVPA compared to the traditional class. The RPE supported the quantitative results
of HR in class intensities. The qualitative results showed that the recreational class gained the
highest number of positive responses, followed by the traditional class, while the circuit/HIIT
received fewer positive responses. Conclusion: The circuit/HIIT was the strategy that achieved
the highest percentages in MVPA, followed by the recreational and traditional classes. All
classes achieved values greater than 50% of class time in MVPA. Qualitatively, the results
showed greater fun, motivation, and engagement among students in the recreational model,
followed by the traditional class, and, finally, the circuit/HIIT.
