Background Physiological adaptations in military jungle survival training have not yet been studied. Knowledge about the relationship between the insulin-like growth factor type I (IGF-I)/insulin-like growth factor binding protein type 3 (IGFBP-3) system and survival activities in a jungle environment can improve readiness and prepare Brazilian Air Force cadets for this kind of battlefield. Our goal was to assess changes in body composition and serum concentrations of the IGF-I/IGFBP-3 system in Brazilian Air Force cadets during five-day Amazon rainforest survival training and whether differences in sex influence these variations. Methods In the five-day survival training, variations in body composition and serum levels of IGF-I and IGFBP-3 were observed. The sample consisted of 14 male cadets (21.71 ± 1.64 years) and 6 female cadets (22.00 ± 1.41 years). Changes were assessed before and immediately after the survival training. Results The male cadets’ body mass (pre: 73.89 ± 8.79 kg; post: 69.57 ± 8.44 kg), body fat (pre: 11.43 ± 4.15%; post: 10.16 ± 4.19%), IGF-I serum concentrations (pre: 252 ± 72 ng/mL; post: 140 ± 42 ng/mL), and IGFBP-3 serum concentrations (pre: 4.90 ± 0.67 ng/mL; post: 4.22 ± 0.73 ng/mL) were significantly reduced (P < .01). In the female cadets, the mean body mass values (pre: 60.98 ± 8.82 kg; post: 57.91 ± 9.01 kg), body fat (pre: 19.20 ± 5.03%; post: 17.19 ± 4.77%), and IGF-I serum concentrations (pre: 202 ± 50 ng/mL; post: 108 ± 29 ng/mL) also decreased significantly (P < .01) after survival training. Finally, the cadet’s sex does not affect the variations of IGF-I (P = .46) and IGFBP-3 (P = .205) serum concentrations. Conclusions These findings all suggest that changes in body mass and body fat, as well as variations in the IGF-I/IGFBP-3 system, corroborate the need for military readiness preparation. Equivalent changes in both sexes indicate probable equal recovery intervals after survival training.
Background: Dyslipidemia is a disorder caused by alterations in the plasma concentrations of one or more lipids/lipoproteins. It is considered a metabolic disease that exposes the body to various harmful and even fatal events, one of which is the increased risk for cardiovascular diseases. Military police officers, in turn, are exposed to high physical and psychological risks and may suffer from cardiovascular diseases more than other professions. Objectives: In this sense, the objective of the present study was to evaluate the lipid profile of military police officers working in a special operations group to identify the prevalence of dyslipidemia among the subjects. Methods: In total, 65 volunteers participated in the study, members of a special operations battalion (37.26 ± 5.77 years of age). Blood collection was performed after 12 hours of fasting to analyze the following variables: Total cholesterol, triglycerides, LDL-c, and HDL-c. Results: The total cholesterol value presented the highest variation, since 77% of those evaluated showed altered values. Regarding the values of HLD, LDL, and triglycerides, most subjects (89%, 72%, and 80%, respectively) presented results within normal values Conclusions: It can be concluded that most participants presented regular values for most of the analyzed lipid fractions, which could contribute to their demands during their work activities. It is believed that the positive results seen in this group, which is heterogeneous with respect to age, are due to an extremely rigorous selection process and a training program that elevates the individuals to the rank of elite soldiers within the Brazilian military police.
Polycystic Ovary Syndrome (PCOS) is an endocrine disorder 5 to 16% present in of women of reproductive age, which can suffer alterations in reproductive, cardiometabolic, hormonal and cardiovascular functions that can culminate in the development of other diseases. One of the treatments consists of improving life habits like physical exercise practice. Systematic reviews and studies in recent years have pointed out that the training protocols performed on women with PCOS were mostly conducted without control, randomization and personalization for this disease. Thus, the present study aims to investigate Pubmed database on the last year (between 05/31/2019 and 05/31/2020) if there are recent publications of randomized controlled trials (RCTs) that investigate the effects of physical training in women with PCOS.
