| Research Abstract |
We investigated 24-hour ambulatory blood pressure (BP), systolic BP (SBP) elevation during 2 hours after wake-up (Morning BP surge, MBPS), BP elevation during resistance exercise and BP rise during walking in 243 middle-aged and older individuals and assessed the relationships to daily physical activity and physical fitness. The salient findings of this study were as follows;
1. Mean SBP during ambulatory blood pressure monitoring and MBPS were correlated with heart rate elevation during exercise.
2. The lowest SBP during sleeping was correlated with body flexibility.
3. SBP response to resistance exercise was exaggerated in aged individuals but attenuated in individuals with increased levels of daily physical activity.
4. SBP response to walking in older individuals was higher on lower air temperature days and that in middle-aged individuals was higher in individuals with increased body mass index (BMI).
