AB [EN] The aim of this study was to examine the influence of physical fitness on cardiacautonomic control in passengers prior to, during and following commercial flights.Twenty-two, physically active men (36.4 ± 6.4 years) undertook assessments ofphysical fitness followed by recordings of 24-h heart rate (HR), heart rate variability(HRV), and blood pressure (BP) on a Control (no flight) and Experimental (flight) day.Recordings were analyzed using a two-way analysis of variance for repeated measureswith relationships between variables examined via Pearson product-moment correlationcoefficients. Compared to the Control day, 24-h HR was significantly greater (>7%)and HRV measures (5–39%) significantly lower on the Experimental day. During the1-h flight, HR (24%), and BP (6%) were increased while measures of HRV (26–45%)were reduced. Absolute values of HRV during the Experimental day and relativechanges in HRV measures (Control-Experimental) were significantly correlated withmeasures of aerobic fitness (r = 0.43 to 0.51; −0.53 to −0.52) and body composition(r = −0.63 to −0.43; 0.48–0.61). The current results demonstrated that short-termcommercial flying significantly altered cardiovascular function including the reductionof parasympathetic modulations. Further, greater physical fitness and lower body fatcomposition were associated with greater cardiac autonomic control for passengersduring flights. Enhanced physical fitness and leaner body composition may enablepassengers to cope better with the cardiovascular stress and high allostatic loadassociated with air travel for enhanced passenger well-being.
