This study investigated whether these 24-hour movement behaviors help explain the link between adolescents’ perceived…
Assessing the damage: Analyzing the impact of the Covid-19 pandemic on accelerometer-assessed 24-hour movement behaviours in Brazilian adolescents
Differences in the 24-h movement behaviour composition comparing the cross-sectional samples, although statistically significant, were considered trivial and unlikely to have a substantial practical impact. However, considerable differences were observed in the prospective analysis. The results suggest that most of the observed changes over time were expected as a natural consequence of aging during high school, with only a small portion attribut…
