During the season it is more than 3 hours a day, plus the weekend games, but in the off season it is much less. But it requires a lot of time management. An athlete can’t leave a project till the last minute because there might not be enough time to get it done if there is a road trip. My daughter was very organized. She had mandatory study tables her first semester and used those 8-10 hours a week to actually study. Do you count those 8 hours as ‘athletic’? I think they are academic. But scheduled.
And there is personal care that needs to be taken care of too, like eating right, working out, scheduling laundry time, and lots and lots of sleep. Again, not counting this as athletic time but if you want to, that’s fine. I know that as a college bum myself I did my projects at the last minute, often while doing laundry at midnight and eating junk food. My daughter didn’t have that option.
