Serie A has been postponed since March because of the COVID-19 crisis, although most teams returned to individual training this week.
Spadafora has previously reiterated that team training will not resume before 18 May, despite the government allowing players to return to club facilities.
With Germany's Bundesliga set to restart its 2019-2020 campaign on 16 May, Spadafora said in a Facebook video on Sunday (AEST): "We will imminently learn the verdict of the scientific committee on the [Italian Football Federation] FIGC's medical protocol.
"We are also ready to propose guidelines to the committee for training sessions involving all team sports and guidelines to open up facilities, including gyms, swimming pools and dance halls, that will allow all those who work in sport to resume their activities.
"Finally, we are also working with the Ministry for Education, for Equal Opportunities and Families to reopen sporting facilities, so we can guarantee a summer of sport for the youngest members of our society.
"So, one step at a time, sport will return. It'll be stronger than ever."
Defending champion Juventus is a point clear of Lazio through 26 matches.
