Gravitational Acceleration Test Results According to Functional Movement Screen and Morphological Symmetry Results of Air Force Cadets

Abstract

Objectives: Strong physical abilities and morphological symmetry are important factors for pilots to withstand aerial G-tolerance. Therefore, this study aimed to determine the symmetry difference between cadets by measuring functional movement screen (FMS) and functional leg length of Korea Air Force cadets for the first time and to understand the pass–fail relationship of the G-test by variable. Methods: Altogether, 72 fourth-year cadets (male, 72; mean age, 23.8 ± 0.6) were included in the study, and their body composition, FMS, functional leg length, and G-test results were measured. Results: The G-test results according to the FMS score revealed that the G-test passed (GP) group scored significantly higher than the G-test failed (GF) group in terms of the following: hurdle step (p =0.000), inline lunge (p = 0.006), active straight leg raise (p = 0.001), and T = trunk stability push-ups (p = 0.001). Conclusions The G-test results according to leg length demonstrated a significant difference between both groups. Morphological symmetry of leg length is an important factor in the functional aspect of exercise and exercise persistence. Moreover, a high G-test success rate can be expected if a follow-up study is conducted to improve the symmetry and balance of the body of air force cadets.
