Just one example.
The D1 soccer commitment in a Power 5 conference is about 2 hours per day on the field plus travel weekends which are 3-4 weekends during the season. Travel weekends start Wednesday evenings and end Sunday nights or Monday mornings. So, you’ll have missed classes on Thursdays and Fridays when traveling and also missed classes at home on game days. Plus there will be team meetings, but this will vary.
Off season is about the same practice schedule (2 hours per day), but there are some days with weight lifting. And then there are the acupuncture and other treatment sessions which will add to your S’s schedule.
