Cardio-postural Blood Pressure Control

How do the cardiac baroreflex and muscle pump systems work together to maintain blood pressure when you are standing? Listen as Associate Editor Robert Hester interviews authors Kouhyar Tavakolian (University of North Dakota) and Andrew Blaber (Simon Fraser University), along with content expert Jerry Collins (Alabama A & M University) about the innovative study by Xu et al. The authors explored the direct neural component between the brain and the muscle pump to help maintain blood pressure during a sit-to-stand transition, as well as a simple standing posture. Employing state-of-the-art analytics such as the wavelet transform coherence method and the convergent cross-mapping method, the authors simultaneously monitored the interrelationships between the human subjects’ cardiovascular, musculoskeletal, and balance systems. While the current study investigated young, healthy subjects, are there future implications for helping stroke patients, the elderly, or concussion injury patients? Listen and learn more.
