May warrant caution with evening high-intensity exercise for sleep optimization in athletes; leaves open recovery and performance effects.
Does night-time high-intensity exercise alter sleep architecture in well-trained male runners?
Night-time high-intensity exercise modifies sleep architecture, increases core body temperature, and elevates nocturnal heart rate in well-trained runners.
