TREINAMENTO FÍSICO MILITAR, FORÇA MUSCULAR E COMPOSIÇÃO CORPORAL DE MILITARES BRASILEIROS
2018
ABSTRACT Introduction: Since 1965, the Brazilian Army (BA) has participated in peacekeeping missions of the United Nations (UN), sending large contingents to various parts of the world, such as Angola, Mozambique, East Timor and Haiti. To do so, the military must be in a minimum physical condition to face any obstacles in the course of action in the theater of operations. Objective: To verify the effects of Military Physical Training (MPT) on muscular strength of upper limbs, anthropometric variables and body composition of Brazilian military personnel of the 24th UN peacekeeping mission in Haiti. Methods: The sample consisted of 192 male soldiers with mean age of 23.2 ± 3 6 years. They observed a weekday residential regime, with a defined schedule of meals and activities and time off on weekends. The MPT was applied four times a week, 90 minutes long for 14 weeks and involved aerobic and resisted exercises. In the pre- and post-MPT period, body mass (MC), height, waist circumference (WC) and abdomen circumference (AC) were measured to calculate body mass index (BMI) and fat percentage (%F) through the protocol of Salem.. In addition, 12-minute run tests, push-ups, pull up and abdominal flexions were performed to calculate the Rogers Index (RI). Results: When comparing pre- and post-MPT, a significant difference was observed in all anthropometric variables and body composition (BM, BMI and %F) and in the RI for the upper limb muscle strength. Conclusion: The 14-week MPT indicates an improvement in the anthropometric and body composition variables, as well as an increase in upper limb muscular strength in Brazilian soldiers of the UN peacekeeping contingents in Haiti. This study concluded that RI could be an effective tool for assessing military muscular strength. Level of Evidence II; Therapeutic studies - Investigating the results of treatment.
