ABSTRACT: BACKGROUND: Several studies have reported an age-related decline of physical activity (PA). We examined the impact of 4 important transitional periods – adolescence, the beginning of post-secondary education, entry into the labor market, and parenthood – on the PA of participants in the Trois-Rivières quasi-experimental study. METHODS: In 2008, 44 women and 42 men aged 44.0 ± 1.2 years were given a semi-structured interview; the frequency and duration of physical activities were examined during each of these transition periods. Subjects had been assigned to either an experimental program (5 h of weekly physical education (PE) from Grades 1 to 6) or the standard curriculum (40 min of weekly PE) throughout primary school. RESULTS: The percentage of individuals undertaking ≥5 h of PA per week decreased from 70.4 to 17.0% between adolescence and mid-life. The largest decline occurred on entering the labor market (from 55.9 to 23.4%). At mid-life, there were no significant differences of PA level between experimental and control groups. Men were more active than women at each transition except for parenthood. CONCLUSIONS: Our results highlight a progressive non-linear decline of PA involvement in both groups. Promotion initiatives should target these periods to prevent the decline of PA.
