About

Objective: The main objective of the present study was to examine the effects of an intermittent teaching unit based on the use of activity wristbands and behavior modification strategies on high school students perceptions of autonomy support, satisfaction of basic psychological needs, motivation toward Physical Education and physical activity, intention to be physically active, and habitual physical activity levels.

Materials and methods: An initial sample of 353 high school students (final sample = 175; 45.7% females; mean age = 13.3 ± 1.2 years) from two public high schools were cluster-randomly assigned into the intermittent (n = 100) and control (n = 75) groups. The intermittent group performed an intermittent teaching unit twice a week for eight weeks. Specifically, the last 15 minutes of each lesson were used. As the main strategy to promote the practice of regular physical activity, students wore an activity wristband the whole day during the intervention period. Additionally, other behavior modification strategies were also applied (e.g., educational counseling, physical activity goals or reminders). The control group also performed two Physical Education sessions a week during the intervention period, but without using wristbands or other behavior modification strategies. Before and after the intervention, as well as at the end of the follow-up period (six weeks), students' physical activity practice mediators and physical activity levels were measured by validated questionnaires.

175 participants in 2 patient groups

Intermittent group

Experimental group

Description:

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).

Treatment:

Other: Intermittent teaching unit

Control group

Active Comparator group

Description:

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 developed in the intermittent group.

Treatment:

Other: No intervention group
