VISCERAL FAT, PHYSICAL FITNESS AND BIOCHEMICAL MARKERS OF BRAZILIAN MILITARY PERSONNEL

Abstract

ABSTRACT Introduction: Adipocyte volume (fat accumulation) in different parts of the body may play different roles in the metabolism and in the appearance of cardiovascular risk factors. Most studies indicate that the regional distribution of body fat seems to be more important than excess adiposity per se. High levels of physical activity are associated with lower total and visceral body fat levels. Military physical training is of paramount importance for the health and performance of soldiers in the Brazilian Army. In this context, physical evaluation will provide data on the main physical benefits involved in military tasks. Objective: Verify the relationship between visceral fat (VF), physical performance and biochemical markers of soldiers in the Brazilian Army. Methods: The sample consisted of 41 (38.9 ± 2.2 years) Brazilian male military personnel. VF was obtained with a Dual Energy X-Ray Absorptiometry densitometry device. The biochemical analysis included fasting glycemia, triglycerides (TG) and HDL-C levels. Physical performance was evaluated through two tests (12-min run and pull-ups). The Shapiro-Wilk test confirmed the normality of the variables. Pearson's correlation test was then applied, with a p-value of <0.05. Results: Significant negative correlations of VF were found with the results of both physical tests (Pull-ups r = −0.59; 12-min r = −0.61). The only biochemical variable that had a significant positive correlation with VF was TG (r = 0.44). Conclusion: The results of this study showed a significant negative association between VF and physical tests. A significant positive association between VF and TG was also found.
