Its "Adapt at Home" challenge aims to reduce isolation and improve quality for thousands of wounded war veterans, as well as young people and adults with disabilities nationwide.

Activities that would have be performed in person outside are now being moved into the home after the pandemic closes most facilities.

Glenn Merry, DSUSA executive director, said: "DSUSA knows all about adapting, adaptive sport is what we do.

"So, on March 17 when the State of Maryland began closing business as usual, the organisation quickly pivoted its focus to bring those programmes and activities to life online.

"Where others see adversity and obstacles, our natural inclination is to find how to adapt around it.

"We have an office of passionate people, motivated to create opportunities.

"Within 48 hours, we launched the first ever digital platform to serve our community."

The platform has more than 100 live and recorded sport and fitness activities led by coaches and designed for those with disabilities.

Yoga and strength training are two such activities.

Athletes have been encouraged to film their home workouts to strengthen the Adapt at Home community and have been asked to call on friends to share workouts. 

Participants so far include Paralympic snowboarders Brittany Couri, Noah Elliott, Brenna Huckaby and Nicole Roundy.

Long jump world record holder Lex Gillette is among those backing the initiative.

"I think that we as athletes have the ability to adapt and be creative, and those are going to be huge during this time," Gillette said.

"Training looks different given the recommendations and guidelines in place for our country, but you have to keep moving so you don't go stir crazy.

"It may be difficult if you have limited space, but the idea here is to try and get some work in, and again, creativity is the name of the game."

There have been more than 792,000 confirmed cases of COVID-19 in the United States to date, resulting in the deaths of at least 42,500 people.
