Factors behind Leisure-Time Physical Activity Behavior Based on Finnish Twin Studies: The Role of Genetic and Environmental Influences and the Role of Motives

Figure 2

The summary of the final genetic models for leisure-time physical activity between both ages of 16.2 and 24.5 years and ages of 29.6 and 35.6 years in Finnish twin studies. It is important to note that the cohorts used in the models between ages of 16.2 and 24.5 years and between ages of 29.6 and 35.6 years are not identical. Genetic and environmental influences are shown as percentages; upper value is for men and lower value is for women. Confidence intervals (95% CI) are shown in the parentheses. Additive genetic, shared environmental, and specific environmental correlations between the baseline and follow-up results are shown as curved arrows. The more detailed summaries for models are presented in the publications of Aaltonen et al. [27, 28].
