Relationship between length of practice time and team strength

Would the longer the practice time, the stronger the team?

The snow country prefecture like Hokkaido cannot practice at the ground with snow from October until about March. Players will practice for 6 months at the indoor gym. When it is an indoor gym, it is variously restricted compared to the ground. Obviously, the high school team in the snow country is disadvantageous.

Still, why can teams in Hokkaido and snow country prefectures win or get to good points?

It shows that it cannot be said that team will be stronger as they practice for long time. Again, I would like you to think about practice time. Too much practice time.

Of course, not only the practice time, but also various other things such as quality, ability of the players and so on are involved, so it is not possible to limit the length of the exercise time unconditionally.
