| Abstract |
The purpose of this study was to grasp the activity levels of navy soldiers according to their type of duty(administration, warship, aviation, submarine), thereby providing basic data for the development of fitness training programs suitable for each group. Subjects in the study were 55 in total, comprising 15 from warship, 15 from submarine, 10 from aviation, and 15 from administration. For data collection, actigraph units were put on there waist for three weeks, and the number of steps and calorie were extracted for applicable data. In addition, it was arranged so that measurements could be conducted at the same time among types of duty the different group. As a result of the study, it was found that the weekday mean and weekend mean of steps according to the different groups were 3,503 steps and 2,000 steps for warship personnel, 2,249 steps and 2,148 steps for submarine personnel, 4,628 steps and 3,776 steps for aviation personnel, and 7,388 steps and 14,682 steps for administrative personnel, respectively. On weekdays, the number of steps was greatest among the administrative personnel, followed by aviation, warship, and submarine personnel. At weekends, the number of steps was greatest among administrative personnel, followed by aviation, submarine, and warship personnel. Thus, it was found that the activity level was the lowest among submarine personnel on weekdays, and among warship personnel at weekend. In conclusion, the comparison of activity levels among the four groups of navy showed that their activity levels were not so high as expected, due to the special characteristics of their working environment. In particular, the activity levels of warship personnel and submarine personnel fell short of the ordinary recommended level for health due to spatial constraints and the special characteristics of their service activities. Particularly, the activity level of the submarine personnel was too low due to the constraint of their working condition in narrow space, and thus it is presumed that it will be necessary to develop special training programs and take measures for their health management. |
