The aim of this study was to explore the relationship between personality and physical activity (PA) in a sample of Croatian twins. Because it is a twin sample, we could examine the relationship between physical activity and personality on a phenotypic level, as well as explore if the same genetic and environmental factors contribute to physical activity and personality. Data were collected from 339 twin pairs (105 MZ and 234 DZ) aged between 15 and 22 years. On the phenotypic level significant correlations between physical activity and two personality traits (neuroticism and extraversion) were found. Univariate analyses indicated substantial heritability of physical activity as well as two personality traits. Therefore we run Cholesky decomposition to assess how much of the variance in physical activity is explained by personality traits, neuroticism and extraversion. Results of Cholesky decomposition indicated that heritable differences in physical activity were mostly due to specific genetic and environmental influences and only in part accounted for by the genetic architecture of neuroticism and extraversion.
