This study evaluates the influence of diet and physical exercise on plasma lipid concentrations - total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), and the TC:HDL-C ratio, in a homogeneous (age, sex and anxiety levels) group of young pilots divided into the following groups: A. uncontrolled diet and exercise programme; B. controlled diet and uncontrolled exercise programme; C. controlled diet and exercise programme (n = 90). The dietary intake was a typical Mediterranean diet, which was supervised by the Flight Surgeon. The exercise was based on a physical training programme for pilots, directed by the Physical Training Officer. The State-Trait Anxiety Inventory test was performed to evaluate the anxiety levels. This test was supervised by a psychologist. The results showed a marked difference in all the lipid parameters studied between groups with an ad libitum diet versus groups with a controlled diet, this difference being demonstrated by TC and TG concentrations lower in the group with a controlled diet, than in the group with an ad libitum diet. A difference in HDL-C concentrations and TC:HDL-C ratio was found between groups with regular physical training (high HDL-C concentration and low TC:HDL-C ratio) versus groups with unlimited exercise (low HDL-C concentrations and high TC:HDL-C ratio). No differences in the state and trait of anxiety were found among any of the groups. Nevertheless, all the pilots showed a considerable increase in their anxiety state over their own anxiety trait.
