Impact of Training on Hemodynamic Parameters Measured During Anti-G maneuvers
Journal Title: The Polish Journal of Aviation Medicine, Bioengineering and Psychology - Year 2013, Vol 19, Issue 1
Abstract
Introduction. Physical training for pilots has been a focus of attention for a long period of time now. In this publication we assess the cardiovascular response to a series of anti-G straining maneuvers (AGSM) at baseline and after 2 months of muscle straining exercises and performing anti-G respiratory maneuvers (AGRM). Methods. The study included 10 men - five F-16 pilots and five students from the Polish Air Force Academy in Dęblin. The following parameters were recorded: heart rate (HR), systolic blood pressure (SBP), diastolic (DBP) and mean (MAP), stroke volume (SV), cardiac output (CO), left ventricular work index (LVWI), total peripheral resistance (TPR), left ventricular ejection time (LVET), pre-ejection period (PEP). Results. It was demonstrated that all parameters except for CO were significantly different after training. Discussion:While performing AGSM, blood circulation becomes faster, which results in changes of the specific hemodynamic parameters. These parameters can provide information on the cardiovascular response to AGSM. Conclusions. AGRM training in a "chair" position positively impacted response changes in hemodynamic parameters determining the +Gz acceleration tolerance. A non-invasive method of recording hemodynamic parameters using impedance may be useful for an assessment of the effectiveness of AGSM.
