Playing with Pubmed and the following search equations to update my course, I found more than 150 published articles (2020/09/02): (“physical activity”[Title/Abstract]) AND (COVID[Title/Abstract]) and (“physical exercise”[Title/Abstract]) AND (COVID[Title/Abstract]).

I propose a rapid classification of references by countries. I added international investigations. The top 6 countries were : Italia (10), Canada (7), US, China, Spain (4) and Brazil (3).
