Introduction and objective. This study aimed at investigating the relationship between the lipid index (WS) in the examined cadets and duration of exposure to +Gz in the human centrifuge. Materials and methods. The study involved 19 first-year cadets of the Polish Air Force Academy in Dęblin. Tests in the human centrifuge were repeated twice, i.e. prior to (test I) and 45 days after (test II). After exposure to +Gz, the examined cadets were divided into 2 groups. Group I (N=11) included cadets subjected to a shorter total duration of exposure to +Gz, while group II (N=8) included cadets with a longer total duration of exposure to +Gz. Total cholesterol (TC), high density lipoprotein (HDL), triglycerides (TG), and apolipoproteins A 1 and B were assayed in blood serum prior to (assay A) and after (assay B) both exposures to +Gz. Low density lipoprotein (LDL) level was estimated from the Friedewald formula. WS is an own mathematical algorithm. Results. WS was higher in group II, assay A -10.0 and B -10.08 of test I in the human centrifuge than in group I where the WS values were 6.91 and 6.96, respectively. WS was also higher in group II in assay A -10.0 and B -10.1 of test II in the human centrifuge than in group I -6.96 and 6.80, respectively. Conclusions. The higher value of WS in group II, both after the first and second exposure to +Gz in human centrifuge, in comparison with group I, indicated its usefulness for determination of the maximum capability of applying acceleration of the interval type during training in the human centrifuge.

The objective of the study was to assess the baseline anthropometric parameters and anaerobic effi ciency of military pilot candidates in two successive classes admitted to the Polish Air Force Academy in Dęblin. The study included all males admitted as aviation pilot students to two successive classes at the Polish Air Force Academy in Dęblin (PAFA). The study group consisted of 35 cadets admitted in 2012 (group I) and 46 cadets admitted in 2013 (group II). The studies were conducted in October 2012 and 2013. The assessment included the measurements of basic anthropometric parameters, bioimpedance evaluation of body composition and evaluation of anaerobic effi ciency in a 30-second Wingate test using a Monark 911 SE ergometer. The mean age in group I was 19.74±1.44 years while the mean age in group II was 19.33±0.99 years. Comparative analysis of anthropometric parameters and body composition revealed no signifi cant diff erences between the two groups of cadets (P>0.05). The mean percentage fat tissue content in both groups was about 18.5%, fat-free body mass was over 81%, percentage muscle tissue content was 55.3% and the mean body water content was 59.5%. No underweight or obese individuals were identifi ed on the basis of BMI values. Overweight individuals were identifi ed in the study groups (20% of cadets in group I and 10.4 % of cadets in group II). The assessment of anaerobic effi ciency revealed no signifi cant diff erences between groups with the exception of minimum power (P=0.02). The somatic build of military aviation pilot candidates is similar to the somatic build of civilian university students in Poland. The baseline values of anthropometric parameters and anaerobic effi ciency of candidates present a realistic potential for developing proper fi tness and effi ciency required from military pilots. anaerobic effi ciency, anthropometric parameters, body composition, cadets, physical fi tness
