That definitely aligns with my experience. My soccer coach in college started our morning practices with a 1hr run. I had my best runs (time/perf) the days I was able to take mini cat naps or zone out as I ran. And in retrospect I think it applies to all my workouts. Unless I was concentrating on learning a technique, generally being in some sort of "empty" state makes me feel more effective and efficient with physical activities. All anecdotal fwiw.
