The primary objective of this clinical trial is to test the efficacy of an innovative multimodal eHealth \& mHealth intervention (focused on emphasizing identity/habit and/or self-regulation) on increasing moderate to vigorous (MVPA) across 12 months among newly retired adults not meeting Physical Activity guidelines at study baseline, thus at higher risk of age-related chronic diseases.
The secondary objectives are to examine whether these approaches improve physical and mental well-being and health related fitness-outcomes.
Principal Research Question 1: Does an intervention focused on identity/habit + self-regulation skills + education (ID) increase moderate-to-vigorous intensity physical activity (MVPA) compared with an intervention focused on self-regulation skills + education (SR), and an education control condition (ED)? Three-arm parallel design single blinded randomized controlled trial. Participants will be randomized to one of three groups (ID, SR, ED) for 12 months duration.
* After the initial screening process, eligible participants will be provided with an accelerometer-mailed or delivered in person-to wear for seven consecutive days. Data collected will verify baseline physical activity levels and determine final eligibility based on adherence to physical activity guideline thresholds. * Participants will visit the lab for fitness testing and complete an online questionnaire See below in "detailed description" the breakdown/delivery given for each of the 3 arms.
Adults aged 60-70 years
