Grit og fysisk aktivitet : Utviklingen av grit ved endring av fysisk aktivitetsnivå blant norske ungdommer: En to-års oppfølgingsstudie

Abstract

The purpose of the study was to investigate the development of grit due to changes in physical activity in Norwegian youth. In addition, the study wanted to investigate differences in grit based on school type (age) and gender. This longitudinal study is part of a larger project called "The Relevance of Physical Activity Contexts in the Daily Life of Adolescents" (REPAC). The study is based on data from two time points (2014 and 2016). The sample consisted of students from Oslo/Akershus, Østfold and Agder. 1658 (54.4% from first measurement point) students were included in the study. To investigate grit and physical activity level, correlation analyzes and Two-Factor ANOVA (Bonferronis post hoc test) were performed. The results showed that the 13-year-olds scored higher than the 16-year-olds on grit-interest, grit-effort and grit-total, there was no difference when the students were one and two years older. The boys scored higher than the girls on most measurements of grit in the age of 13-16, but no difference between the sexes at the age of 17 and 18. Furthermore, the analyzes showed that there was no change in grit-effort over a two-year period. There was, however, a change in grit-effort due to change in physical activity level. The pupils who had reduced their physical activity level had a reduction in grit-effort, though with a trivial effect. The analyzes further showed a reduction in grit-interest over a two-year period, and the groups based on change in physical activity level changed the same. More research is needed to understand the aspects of grit. Keywords: grit, physical activity, personality traits, youth
