Activity Wristband-based Intermittent Teaching Unit and Students Physical Activity and Its Psychological Mediators

The intermittent group students performed an intermittent teaching unit twice a week for eight weeks aimed at promoting healthy physical activity habits. Specifically, the last 15 minutes of each lesson were used. The rest of lessons' time other contents were worked on with no relation to any health physical activity habit (i.e., acrosport, badminton, basketball, volleyball, soccer and athletics).

The control group students also carried out two Physical Education lessons a week during the intervention period. During these lessons, contents of handball, basketball, alternative sports and traditional games were developed. However, this group did not wear physical activity activity wristbands or receive any behavior modification specific strategy.
