[單字] industrially?

[recary (recary)]

1.Astronauts train industrially often for years their missions, but NASA
                   ___________

  cannot train them to live in zero gravity, which turns out to be a major

  pain in life out there in space.



 【疑惑】請問這裡的industrially該怎麼翻譯會比較符合文意？

         (我查到的意思都跟工業有關...)


Many thanks!
