Abstract
[EN] The aim of this study was to examine the influence of physical fitness on cardiac
autonomic control in passengers prior to, during and following commercial flights.
Twenty-two, physically active men (36.4 ± 6.4 years) undertook assessments of
physical 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 measures
with relationships between variables examined via Pearson product-moment correlation
coefficients. Compared to the Control day, 24-h HR was significantly greater (>7%)
and HRV measures (5–39%) significantly lower on the Experimental day. During the
1-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 relative
changes in HRV measures (Control-Experimental) were significantly correlated with
measures 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-term
commercial flying significantly altered cardiovascular function including the reduction
of parasympathetic modulations. Further, greater physical fitness and lower body fat
composition were associated with greater cardiac autonomic control for passengers
during flights. Enhanced physical fitness and leaner body composition may enable
passengers to cope better with the cardiovascular stress and high allostatic load
associated with air travel for enhanced passenger well-being.
