Investigation and analysis of physical performance of naval aviators

Abstract

Objective To conduct physical performance test of naval aviators, so as to understand its current status, and propose solutions to existing problems. Methods Physical performance test was performed in 95 naval aviators who were divided by age into group 1 (age between 25 and 29), group 2 (age between 30 and 34), group 3 (age between 35 and 39) and group 4 (age between 40 and 44). Then, analyses and comparisons of the obtained data were made accordingly. Results Body fat percentage of group 1 and 2 was significantly lower than that of group 4(P<0.05), and the body mass index and body fat percentage of group 3 and 4 were higher than the normal level. There were no significant differences in vital capacity and step index between the groups. The vital capacity of the aviators was higher than that of the ordinary people, however, there were no significant differences in the level of the step index, as compared with that of the ordinary people. There were no significant differences in the data of grip strength, push-ups, single-leg standing with eyes closed, when comparisons were made between the groups, and they all were higher than those of the ordinary people. The average value of the back strength of the aviators was lower than that of the ordinary people. Vertical jump levels of group 1 and 2 were significantly higher than that of group 3(P<0.05). The seated flexion of group 1 was significantly higher than that of group 3(P<0.05), and the selective response time of group 1 was significantly higher than that of group 43(P<0.01). Conclusions (1) The average data of BMI and body fat for the naval aviators with an age over 35 were excessive, and measures should be taken to control diet and intensify physical exercise. (2) Naval aviators should pay attention to cardiopulmonary tolerance training, so as to improve tolerance capability. (3) Efforts should also be made on the part of naval aviators to intensify training on the lower back muscle strength and avoid occurrence of lower back injury. (4) Naval aviators with an age over 35 should pay more attention to physical performance training, improve physical capacity and delay decline of athletic ability.
