| Outline of Final Research Achievements |
We determined effects of different exercise mode, intensity, and timing on the blood pressure (BP), sleep quality and quantity during nocturnal sleep.
When moderate cycling exercise was performed in evening, systolic BP during nocturnal sleep was lower than that for control condition (i.e., without exercise: C). When tennis was performed in evening, mean and diastolic BPs were lower than that in C condition. Compared to C condition, sleep onset latencies were shorter for moderate cycling and playing tennis in morning. Wake time after sleep onset was shorter for playing tennis in evening than that in C condition. Compared to C condition, sleep onset latency was shorter for playing futsal in night. Percentage of slow wave sleep was larger for resistance training in night than that in the C condition. These findings suggested that sports activities in evening and night could have a residual effect on haemodynamics (i.e. prolongation of post exercise hypotension) in nocturnal sleep.
