TL;DR: The evidence suggests that 30 minutes of daily MVPA accumulated in addition to habitual daily activities in healthy older adults is equivalent to taking approximately 7,000-10,000 steps/day, which approximates 8,000 Steps on days that include a target of achieving 20 minutes of moderate-to-vigorous physical activity (MVPA).

TL;DR: The purpose of this review was to update existing knowledge of "How many steps/day are enough?", and to inform step-based recommendations consistent with current physical activity guidelines.

TL;DR: In this paper, a review of the literature that investigated differences in physical activity and sedentary behaviour before vs during the COVID-19 lockdown was presented, with the majority of studies reporting decreases in physical activities and increases in sedentary behaviours during their respective lockdowns across several populations.

TL;DR: No longer meeting PA guidelines and increased screen time were associated with worse depression, loneliness, stress, and PMH, and self-isolation/quarantine was associated with higher depressive and anxiety symptoms compared to social distancing.

TL;DR: Levels of agreement with objective measurements indicate the GPAQ is a valid measure of MVPA and change in MVPA but is a less valid measure for assessing the effectiveness of interventions to promote MVPA.
