However, the physiological mechanisms underlying the benefits of regular exercise or physical activity in CVDs remain unclear. Journal of the American Heart Association, Ahead of Print.
Resistance training not only can improve or maintain muscle mass and strength, but also has favorable physiological and clinical effects on cardiovasculardisease and risk factors. We also address the utility of resistance training for promoting cardiovascular health in varied healthy and clinical populations.

Results From a total population of 2545 patients (38.8%
ObjectivesNoise pollution has become an increasingly severe environmental issue in modern society and has been recognized for its adverse effects on cardiovasculardiseases. Hypertension induced by noise exposure has garnered significant research interest and a large quantity of studies have been conducted.

Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. Dozens if not hundreds of (albeit observational) studies have linked a short sleep duration to a number of health conditions including type 2 diabetes and cardiovasculardisease. on Tuesday, and 7 on Wednesday.
Our body’s physiological processes oscillate on a 24-hour cycle known as the circadian rhythm. Circadian rhythms in blood pressure and heart rate, among other functions, are crucial for cardiovascular health and preventing cardiovasculardisease. How could ALAN and the SCN affect cardiovascular health?
The angiotensin-II type 1 receptor is an important G protein-coupled receptor involved in the regulation of cardiovascular function and has been implicated in the progression of cardiovasculardiseases.
Abstract: The renin angiotensin aldosterone system (RAAS) is a paramount target for the pharmacological treatment of cardiovasculardiseases. Next, a physiology-based PK model for enalapril and enalaprilat was developed and coupled to the RAAS model. For all drugs, the error numerics were acceptable.
Cardiovasculardiseases account for a significant portion of the worldwide mortality rate. This aroused interest among the specialised scientific community, seeking for solutions based on non-clinical and clinical investigations, to shed light onto the physio-pathology of cardiovascular impairment.
Joseph Watso, PhD, is an Assistant Professor in the Department of Nutrition & Integrative Physiology at Florida State University. Joe directs the Cardiovascular & Applied Physiology (CAP) Laboratory which has the mission to advance knowledge on cardiovasculardisease prevention and treatment strategies.
Early identification allows for timely initiation of guideline-directed medical therapy for secondary prevention of cardiovasculardisease, cerebrovascular disease, and limb events. The VasoGuard V-Series signifies a significant step forward for physiologic testing in international standards compliance.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. Lastly, insufficient sleep is also a massive health liability, leading to cardiovasculardisease, diabetes, and cognitive decline.

Welcome to the Physiology Friday newsletter. On Wednesday, I published a post on the philosophy and physiology of an “exercise pill.” Physiologically Speaking is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber. Acute sleep loss is also insidious.
