Abstract

Abstract : 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). Additionally, at bedtime participants were equipped with a small device worn on the wrist that identified sleep stage. There were no substantial differences in objective indices of sleep between two protocols (total sleep time: 438 ± 76 vs. 457 ± 64 min; P > 0.10). BP during nocturnal sleep tended to be lowered by prior exercise (MAP: 71 ± 5 vs. 68 ± 6 mmHg; P = 0.08). Aerobic exercise in early evening apparently has no acute effect on sleep per se, but seems to have a residual effect on haemodynamics, i.e. prolongation of post-exercise hypotension.
