Variación del porcentaje de grasa en cadetes durante el periodo de instrucción-adaptación

Abstract

OBJECTIVE: To compare the body mass index (BMI), body fat percentage and the skin folds before and after the physical training plan for the first military course during the instruction - adaptation period in the “Base Paccar” from October 25 to December 3, 2011 in the “Eloy Alfaro” Military School. METHODS: This is a matched case-control study with previous and further observation. It took place in the Military School "Eloy Alfaro from October to December 2011". It was made with a sample of 141 cadets, 116 men and 25 women. The variables studied included age, gender, skin folds (sf): triceps (t), subscapularis (se), suprailiac (if) and abdominal (ab), body fat percentage (% BFP) and body mass index (BMI). Analysis was performed using variables through McNemar Chi Square's Test, considering significant p <0.05 RESULTS: Physical military training was carried out by 116 men and 25 women that corresponded to 82% and 18% respectively. The cadets' BMI slightly varied in percentage and there was no statistically significant difference. The % BG decreased substantially in both cadets with p = <0.05. In the 4 skin folds measured in males decreased significantly. However a p = <0.05 for PC suprailiac and abdominal was only found in women. CONCLUSION: With a planned macro cycle, supervised during 6 weeks, it was possible to reduce fat mass and increase lean mass, developing an adequate physical condition for military performance. However, gender differences should not be forgotten.
