Rethinking Physical Activity Promotion During the COVID-19 Pandemic: Focus on a 24-hour Day
Bibliographic record
Abstract
On March 11, 2020, the World Health Organization (WHO) declared the coronavirus disease 2019 (COVID-19; caused by SARS-CoV-2) a pandemic. By mid-March, all Canadian provinces and territories declared states of emergency, which triggered measures to support the response to the pandemic.1 Some of these measures have posed new barriers for people with arthritis to manage their health and daily activities. With the chance of contracting COVID-19 unclear among people using immunosuppressive medications, many avoided regular activities such as grocery shopping and pharmacy visits to reduce exposure in public spaces early in the pandemic.2 Gyms and swimming pools were closed, leaving people without access to their regular exercise facilities. Even when facilities reopened as local transmission was getting under control, some people were cautious about resuming indoor and group exercise routines. This unprecedented situation has challenged how health professionals support people with arthritis in staying physically active. Worldwide, 28.5% of people were not sufficiently physically active, with nearly 37% in high-income Western countries.3 For more than a decade the main message of physical activity promotion has been centered on achieving concrete goals, namely at least 150 minutes/week of moderate/vigorous physical activity (MVPA), plus strength training at least 2 days a week for adults aged 18 or older.4 Further, people aged 65 and over are advised to engage in multicomponent physical activity that includes balance training for fall prevention. These recommendations are echoed in the 2020 WHO guidelines,5 in which the phrase “every move counts” was coined to encourage participation in any type of physical activity at any duration, and to reduce sedentary time. A recent editorial by Jakiela, et al 6 also recommends that patients with arthritis start by walking 10 minutes/day during the pandemic and gradually increase duration and speed. Maintaining an active lifestyle is … Address correspondence to Dr. L.C. Li, Department of Physical Therapy, University of British Columbia, 2177 Wesbrook Mall, Vancouver, BC V6T 1Z3, Canada.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
