Sports experts warn that injuries could soar as athletes return to regular competition after months of solitary workouts. Working out alone may not be as effective as having a trainer or coach supervise your moves, they say. And as more kids get back onto the field, we can expect a surge in injuries, particularly in contact sports.

Soccer star Christie Pearce Rampone, a three-time Olympic gold medalist and co-author of a new book, "Be All In: Raising Kids for Success in Sports and Life," along with sports neuropsychologist Dr. Kristin Keane, told Yahoo Finance that it takes time to get back into shape.

"You can't just snap your fingers and then expect to be the way you were playing four months ago prior to when all this stuff shut us down," Rampone said. "If you don't prepare yourself, it's going to get ugly."

Professor Keith Stokes from the University of Bath recalled the 20-week, 2011 lockdown of NFL players. When the players returned to competition, he said "there were more frequent soft tissue injuries and a four-fold increase in Achilles tendon ruptures during the first 29 days of return."

Stokes and his colleagues compiled comprehensive guidelines in his research paper on how athletes can mitigate potential losses in physical qualities such as strength, power, and game-specific skills during the COVID-19 crisis.

Rampone advises parents to use this unprecedented time as an opportunity rather than a threat to athleticism, according to Yahoo Finance.

"Try to enjoy this opportunity that you have with your families right now, because once it opens up, it's going to be another transition," she said. She advised that athletes use this time for mental rest and recovery.

"They call it pre-season for a reason," Rampone noted.
