In 1976, the baseline data of the LISE-project, including objectively measured school fitness tests and self-reported LTPA was collected from 56 schools. A stratified random sample including 2 796 children and adolescents aged 9-21 years was drawn from different regions and from both urban and rural municipalities of Finland.
In 2001, the first follow-up was carried out. The postal questionnaire on self-reported leisure-time physical activity, physical fitness and health was sent to the participants taken part in the baseline measurement, at that moment aged 34–46 years. 2396 questionnaires was sent and 1 820 responses received. In addition, a small sub-sample (n=64) took part in objectively measured physical fitness tests and health measurement in Pajulahti training center.
In 2021, the second follow-up was carried out. In addition to self-reported leisure-time physical activity, physical fitness and health, the second follow-up postal questionnaire assessed participant’s work ability. The questionnaire was sent to 2286 participants, aged at that moment 54–66 years, of which 1042 responded. In addition to the survey, the participants were asked an informed consent to take part in the forthcoming measurements of the project.
