Resumo
O desempenho de funções dos profissionais das Forças Armadas, das Forças de
Segurança e Ordem Pública e das Forças de Resgate e Salvamento (populações táticas) é vasto
e heterogéneo. Como tal, garantir que estes reúnem a condição física necessária para o
cumprimento dessas funções é fundamental. Nesse sentido o presente trabalho tem como
objetivo analisar a influência da composição corporal e da aptidão física no desempenho de um
circuito militar em Cadetes Alunos da Academia Militar (AM).
Seguindo uma metodologia hipotético-dedutiva, 30 Cadetes Alunos masculinos do 4.º
ano da AM foram avaliados em três áreas: (1) composição corporal, através do índice de massa
corporal e da percentagem de massa gorda; (2) aptidão física, através de testes de predição geral
(teste de senta e alcança, teste de salto de contramovimento, teste de flexões de braços na trave,
teste de extensões de braços no solo, teste de prancha de antebraço, teste de força de preensão
manual, teste de Cooper, teste T, running aerobic sprint test, y-excursion balance test, seated
leg press test, seated chest press test e seated row test); (3) aptidão para a função através do
circuito militar: Triatlo AM (com uma extensão de 1200m e 16 tarefas militares).
Realizámos o nosso estudo estatístico, descritivo e de inferência, sendo este último
baseado na análise de correlações bivariadas e regressões lineares (métodos enter e stepwise)
entre os dados da composição corporal, da aptidão física e da aptidão para a função.
Os resultados sugerem a inexistência de correlação entre a composição corporal e o
desempenho no circuito militar. Não obstante, verificaram-se dados estatisticamente
significativos entre a aptidão física e a aptidão para a função, nomeadamente nos valores
relativos do seated row test (r=-0.407, p=0.025) e do seated chest press test (r=-0.418, p=0.022)
e nos valores absolutos do teste T (r=0.416, p=0.022) e do teste de Cooper (r=-0.619, p=0.001).
Verificou-se também a existência de capacidade de predição do desempenho do circuito militar,
com um coeficiente de determinação de 53% (R
2=0.530), tendo em consideração a fórmula:
𝑌 = 1308,042 − 164 × (𝐶𝑜𝑜𝑝𝑒𝑟) − 150,237 × (𝑅𝑒𝑙. 𝑆𝑒𝑎𝑡𝑒𝑑 𝐶ℎ𝑒𝑠𝑡 𝑃𝑟𝑒𝑠𝑠).
Assim epilogamos que a força relativa do upper body, a agilidade e a potência aeróbia
estão correlacionados com o desempenho do circuito militar, sendo possível predizer o mesmo,
com um coeficiente de determinação de 53%, a partir do teste de Cooper e do seated chest
press test. Palavras-Chave: Desempenho Físico Funcional, Aptidão Física, Prontidão.
The duties performed by professionals from the Armed Forces, the Law Enforcement Forces, and Fire Fighting and Rescue Forces (tactical populations) are vast and heterogeneous. As such, ensuring that they meet the physical fitness necessary to fulfil these functions are essential. In this sense, the present work aims to analyse the influence of body composition and physical fitness on the performance of a military circuit in Cadets of the Portuguese Military Academy. Following a hypothetical-deductive methodology, 30 male 4th year Portuguese Military Academy Cadets were evaluated in three areas: (1) body composition, through body mass index and fat mass percentage; (2) physical fitness, through general prediction tests (sit and reach test, countermovement jump test, pull-up test, push-up test, forearm plank test, handgrip test, Cooper test, T-test, running aerobic sprint test, y-excursion balance test, seated leg press test, seated chest press test, and seated row test); (3) physical function performance through the military circuit: Military Academy Triathlon (with a length of 1200m and 16 military tasks). We carried out our descriptive, and inference statistical study, the latter being based on the analysis of bivariate correlations and linear regressions (enter and stepwise methods) between body composition, physical fitness, and physical function performance. The results suggest the inexistence of correlation between body composition and performance in the military circuit. Nevertheless, the statistical data reached between the physical fitness and the function fitness were verified, namely in the relative values of the seated row test (r=-0.407, p=0.025) and the seated chest press test (r=-0.418, p=0.022) and the absolute values of the T-test (r=0.416, p=0.022) and the Cooper test (r=-0.619, p=0.001). The existence of performance prediction capacity in the military circuit was also verified, with an predictive coefficient of 53% (R2=0.530), considering the formula: 𝑌 = 1308,042 − 164 × (𝐶𝑜𝑜𝑝𝑒𝑟) − 150,237 × (𝑅𝑒𝑙. 𝑆𝑒𝑎𝑡𝑒𝑑 𝐶ℎ𝑒𝑠𝑡 𝑃𝑟𝑒𝑠𝑠). Thus, we epilogue that the relative strength of the upper body, agility, and aerobic power are correlated with the performance of the military circuit, being possible to predict the same, predictive coefficient of 53%, from the Cooper test and the seated chest press test. Keywords: Physical Functional Performance, Physical Fitness, Readiness.
