Hypothesis
Acute maximal treadmill exercise would not reduce arterial stiffness indices at baseline but would reduce them following the 20 weeks of moderate intensity aerobic exercise training.
Conclusion
In older hypertensives, acute maximal dynamic exercise and 20 weeks of moderate intensity aerobic exercise training had no impact on arterial stiffness.
Supporting Evidence
- Maximal exercise had no impact on arterial stiffness indices immediately and 24 hours following exercise intervention.
- Following 20 weeks of training, arterial stiffness indices remained unchanged at rest and following maximal exercise.
- Eight of nine subjects completed all the measurements and the 20 weeks of exercise training.
Takeaway
The study looked at how exercise affects the stiffness of arteries in older people with high blood pressure, and found that exercise didn't change how stiff their arteries were.
Methodology
Nine older sedentary adults performed maximal treadmill exercise and underwent 20 weeks of moderate intensity aerobic exercise training while measuring arterial stiffness indices.
Potential Biases
Continuation of drug treatment in subjects might have affected vascular function.
Limitations
The study had a small sample size and lacked a control group, which may introduce statistical errors.
Participant Demographics
Nine older sedentary adults (2 men and 7 women, age 68.2 ± 5.4 years) with treated stage 1 hypertension.
