Physiology Friday #215: Sitting Less Improves Blood Pressure

Physiologically Speaking

Even those of us who exercise for 1–2 hours per day still spend a large part of our day engaging in sedentary behavior (which, by the way, exercise doesn’t make us immune to). That’s better, but this behavioral category is missing the benefits of highly structured exercise.

DAIC

A projected rise in heart disease and stroke – along with several key risk factors, including high blood pressure and obesity – is likely to triple related costs to $1.8 trillion by 2050, according to two presidential advisories published in the AHA journal Circulation. to 61% of the U.S. population. to 61% of the U.S.

Exercise And Heart Health: Finding The Perfect Balance

MIBHS

Exercise and heart health— you’ve probably heard of the correlation before. Engaging in exercise can significantly contribute to maintaining a healthy heart and reducing the risk of cardiovascular diseases. A stronger heart can pump more blood with less effort, reducing strain and stress on the cardiovascular system.

Investigators identify novel plasma proteins linked to future risk of hypertension

Medical Xpress - Cardiology

Exercise testing can serve as a powerful physiologic probe to unmask subclinical cardiovascular abnormalities well before disease onset. For example, blood pressure changes during exercise (EBP) can reveal a latent tendency toward future development of hypertension.

How Wearable Tech Can Help Monitor Your Heart Health

MIBHS

Continuous Heart Rate Monitoring Most wearables are equipped with optical heart rate sensors that use light to measure blood flow. By identifying patterns, users can understand how their heart responds to exercise, stress, or relaxation. This allows for continuous tracking of heart rate during various activities and rest periods.

Sympathetic Response to 1-Leg Cycling Exercise Predicts Exercise Capacity in Patients With Heart Failure With Preserved Ejection Fraction

Circulation: Heart Failure

Circulation: Heart Failure, Ahead of Print. BACKGROUND:In heart failure, sympathetic excess and exercise intolerance impair quality of life. In heart failure with reduced ejection fraction, exercise stimulates a reflex increase in muscle sympathetic nerve activity (MSNA) that relates inversely to peak oxygen uptake (VO2peak).

Hemodynamics of Exercise-Induced Hypertension and Relationship to Outcomes in Adults With Coarctation of the Aorta

Circulation: Heart Failure

Circulation: Heart Failure, Ahead of Print. EIH was defined as systolic blood pressure (BP) at peak exercise >210 mm Hg in men or >190 mm Hg in women.RESULTS:In this prospective cohort study, we assessed patients with COA (n=41, age 4314 years, 26 [63%] men) and healthy controls (n=41).
