Correlation between Anthropometric Characteristics, Core Muscle Endurance, and Dynamic Postural Stability (DPSI) Among Military Personnel

Background: One of the problems encountered by active population, especially military personnel, is high incidence of musculoskeletal injuries leading to lose work time and high expenses. These injuries occur due to so many reasons, some of which are considered to be modifiable. The aim of the present study was to investigate correlation between some anthropometrical characteristics, core muscle endurance, and dynamic postural stability. Methods: Thirty commandoes (age of 29.45 ± 4.76) selected for this study and underwent assessments. Some anthropometrical indices (height, weight, BMI) have been measured. Then, McGill standardized testing battery (core muscle endurance tests) and dynamic postural stability test have been conducted. Data were analyzed using Pearson correlation test (P<.05). Results: Pearson correlation test showed no significant relationship between anthropometrical characteristics, core muscle endurance, and dynamic postural stability index. But significant and negative correlation have been found between some anthropometrical features (weight, BMI) and core muscle endurance tests (P<.05). Conclusion: The findings of the present study showed that there are significant correlation between some anthropometrical features (weight, BMI) and McGill tests (plank, side plank). It means that higher weight and BMI, leads to worse McGill test scores. Therefore, weight control -especially among military personnel- is recommended in order to reduce core muscle weakness and prevent low back pain which is a relatively common problem.
