There's a myth about it taking 21 days to form a habit.
There might be new lore about 21 days soon, thanks to the Big Ten.
The conference mandated a 21-day sit-out period for any athlete who tests positive for COVID-19. It was one of several stringent safety protocols, along with daily testing, put in place for the reinstated season after its initial cancellation.
But with a recent outbreak pausing workouts and canning Wisconsin's game at Nebraska this Saturday — plus Badgers quarterback Graham Mertz reportedly set to miss those 21 days — many have questioned the lengthy policy, both what it means and if it's necessary.
Those three weeks roughly encompass three different stages: About 10 days for recovery and isolation to prevent disease spread, thorough cardiac screening to look for myocarditis after two weeks and about a week to re-acclimate physically to the team.
The myocarditis concern was reportedly a major reason why the Big Ten first canceled its season back in August. The swelling of the heart found in some patients after having coronavirus worried conference leaders when it came to the long-term effects for young athletes. There's been conflicting medical opinions on the issue since, with some doctors arguing it's not an issue while others believe the pool of research just isn't vast enough to know for sure.
A recent Journal of the American Medical Association report found so little evidence of myocarditis in COVID-positive college athletes, who were mostly mildly symptomatic to asymptomatic, that it didn't recommend full-scale cardiac testing anymore.
Other Power Five conferences only necessitate a CDC-recommended 10-day sit-out. Some Big Ten athletes and coaches have criticized the Big Ten's rule, including Wisconsin athletic director Barry Alvarez. He told Sports Illustrated the conference should "reevaluate" the policy that never fully sounded right to him in the first place.
