The Differences in Physical Activity Preferences and Practices among High versus Low Active Adolescents in Secondary Schools

This study aimed to (a) identify the differences in the preferred, practiced, and organized physical activity (PA) between high and low physically active Czech and Polish boys and girls and to (b) identify which types of PA are likely to be recommended by low active boys and girls. The research was carried out between 2010 and 2019 in the Czech Republic and Poland and included 6619 participants aged 15 to 19 years. The preferences and practices of the different types of PA and participation in organized PA were identified using a PA preference questionnaire and weekly PA was identified using the International Physical Activity Questionnaire-long form. Czech and Polish boys and girls who were low active preferred less physically demanding and more health-oriented PA compared with high active individuals. Power exercises and participation in organized PA are the most significant predictors of achieving at least 3 × 20 min of vigorous PA per week among low active individuals in both countries. Monitoring the trends in the preferred and practiced types of PA among boys and girls is crucial for the effective promotion of PA to low active boys and girls and positive changes in physical education and school health policy.
