On the subject, Catholicism isn't like conservative Judaism. They don't make Sabbath-compliant stoves and ranges for Catholics. So there's perfectly nothing wrong with doing something strenuous on Sundays.
Sundays make perfect sense in Italy, because many of the stores are closed (as opposed to the weekdays and Saturdays) and it's a nice occasion to still get out and do something social in the community. And most people have the day off of work to attend the match.
