Effects of aerobic exercise in early evening on the following nocturnal sleep and its haemodynamic response.

We determined effect of aerobic exercise in early evening on the quality, quantity, and haemodynamic response of subsequent nocturnal sleep in the home. Ten healthy young participants performed two protocols, with/without cycle ergometer exercise (60 min at 50% heart rate reserve) in early evening. Blood pressure (BP) (Holter) and physical activity (accelerometer) were measured from late afternoon of day 1 until noon of next day (day 2).
