Abstract

INTRODUCTION: The number of passengers using aircraft is steadily increasing with the improvement in the air transport business. It requires the investment both in materials and human resources for commercial aircrew members to be able to accomplish their tasks of aircraft safety. Therefore, the aircrew members are required to maintain and improve their mental and physical states to an optimal condition. It is also very important to periodically evaluate a physical condition, which is essential to flight safety.
METHODS
In this study, each of a total of 89 out of a population of 278 korea aircrew members over 50 were examined in three aspects: blood lipids, maximal oxygen consumption, and bone density. The examinee were divided into two groups (HDL-C high group and HDL-C low group) and three parameters described above were compared between two groups.
RESULTS
The results were as follows: (1) TC and LDL-C were significantly higher(p<0.05), and HDL-C, TG and TC/HDL were significantly lower in HDL-C High group than HDL-C Low group (p<0.01). (2) The maximal oxygen consumption was significantly higher in HDL-C high group (p<0.05). (3) The bone density of lumbar spine was significantly higher in HDL-C high group (p<0.01). (4) VO2max were significant (P< .05) correlate to HDL-C.
CONCLUSION
On the basis of the study, an aerobic exercise which helps in improving the maximal oxygen consumption and cardiopulmonary function is considered to be essential for aircrew members to maintain physical conditions for their tasks, and it is desirable to develop more effective aerobic exercise programs.
