Can Breath Holding exercises build strong lungs??

I read about a study years ago, don't ask for a reference or specifics, unfortunately I don't remember. They studied masters athletes to see if they maintained lung function or capacity as they aged. They didn't, their loss in lung function was similar to non-athletes. However, one group studied did maintain their lung function/capacity as they aged, opera singers. So I think exercises can help, but they must be the right exercises.
