The partly structured playgroup consisted of 46 children and the free playgroup consisted of 33 children. The playground activities consisted of 10 sessions each lasting 1 h, executed once per week in the period Mars to May 2017 at a specific playground setting. The partly structured playgroup conducted a movement activity session that included a combination of both structured- and free play activities. The free playgroup engaged in unstructured play, only. To detect the intensity of the physical activity each child carried an accelerometer 1 h the first week and last week of the intervention. Results indicate a significant difference in physical activity level between the two groups for the 5-year-old in the favor of the partly structured playgroup. There was a significant difference between the four-and 5-year-old in relation to physical activity level. No significant difference between the activity in March and May for the whole group was found.197eninfo:eu-repo/semantics/openAccessMotor developmentMovement skillsOutdoor playOrganizationKindergartenChildrenHreyfiþroskiHreyfifærniÚtileikirHreyfileikirÞjálfunLeikskólarLeikskólabörnÍþróttafræðiSport scienceMotor Skillsinfo:eu-repo/semantics/articleFrontiers in Public Health10.3389/fpubh.2019.00197
