Study title

The data from the student interviews was collected in the Let's Move It -project, which studied the sedentary behaviour and physical activity of vocational school students over a one-year period. The first interviews were conducted shortly after the intervention period of about two months. Follow-up interviews were collected about a year after the first ones. The study was funded by the Ministry of Education and Culture (OKM/81/626/2014) and the Ministry of Social Affairs and Health (201310238). The students were divided into control and intervention groups for the study. The intervention group participated in a variety of physical activity and inactivity reduction interventions, such as six Let's move it -group sessions and break-time exercise, and the students had access to equipment such as exercise balls during lessons. In addition, a poster campaign was carried out in schools and materials were made available to students through a website and a workbook. Quantitative data from the project have also been archived (FSD3212, FSD3445 and FSD3446). The interviews followed the interview guidelines and structure, which included four themes: 1) change in physical activity habits, 2) ways to increase, maintain and manage own physical activity, 3) thoughts about physical activity and physical activity identity, and 4) intervention program. A fifth theme, measurement, was also included in the follow-up interview. For example, interviewees were asked what they thought exercise was, what motivated them to exercise, whether they planned their exercise in advance and what exercise goals they had. In addition, interviewees were asked about their views on sitting and how to reduce it. Finally, the intervention group was asked to provide feedback on the project meetings and materials. The follow-up interviews repeated the same themes and also used stimulus pictures and statements. Finally, interviewees were asked about their experiences with the use of the motion sensor....
