[Arterial pressure, physical activity and physical work capacity]

Area of Science:

• Cardiovascular Physiology
• Exercise Science
• Hypertension Research

Context:

• Arterial pressure (AP) regulation during exercise is complex.
• Understanding AP responses to physical exertion is crucial for assessing cardiovascular health and hypertension risk.
• Previous research has explored exercise's effects on blood pressure, but detailed relationships with muscular performance across different populations require further elucidation.

Purpose:

• To investigate the relationships between arterial pressure, muscular performance, and arterial hypertension risk factors.
• To analyze how power working capacity (PWC) and muscular performance (MP) influence systolic and diastolic pressure changes during and after exercise.
• To identify specific physiological parameters that predict arterial pressure responses in normal and hypertensive individuals.

Summary:

• Multivariate regression analysis revealed distinct patterns of arterial pressure response to exercise in males and females, both normal and hypertensive.
• In males, systolic pressure rise was linked to PWC and MP, with hypertensive males showing additional dependence on age, BMI, and heart rate.
• Diastolic pressure responses varied, influenced by PWC, MP, heart rate, and systolic pressure, with specific patterns observed in hypertensive versus normal individuals and across genders.

Impact:

• Findings highlight the differential impact of exercise on arterial pressure in various demographic and health groups.
• Provides insights into physiological markers predicting hypertension risk and cardiovascular response to physical activity.
• Contributes to a better understanding of exercise physiology for clinical and public health applications.
