Yes, this is absolutely the case. I do software as a dayjob, but do an hour or two of heavy physical activity every day (or more on weekends), and sleep great nearly all the time.
When I've had injuries that prevent me from my regular exercise routine, my quality of sleep takes a huge hit. To the point that last time I had a severe ankle sprain, I'd go to a gym (which I don't normally do) just to use one of those arm bike machines to tire myself out.
