Resumo: O objetivo do presente estudo foi verificar o efeito do treinamento físico obrigatório aplicado pela corporação de bombeiros no nível de aptidão física e composição corporal de bombeiros recémadmitidos. Quarenta e seis bombeiros recém-admitidos, do gênero masculino (23,9 ± 2,9 anos), foram avaliados em relação à capacidade aeróbia (teste de 12 minutos de Cooper), potência anaeróbia (Runningbased anaerobic sprint test – RAST), antropometria (massa corporal, estatura e circunferência abdominal) e composição corporal (percentual de gordura) pré e pós um programa de treinamento obrigatório de 27 semanas, sob a orientação do comando dos bombeiros. A normalidade de distribuição dos dados foi verificada pelo teste de Shapiro-Wilk, e as variáveis comparadas nos dois momentos de avaliação pelo teste t de Student para amostras pareadas, além disso, foram verificadas as diferenças percentuais e tamanho de efeito nas variáveis pré e pós-treinamento; o nível de significância adotado foi de P < 0,05. Os principais resultados mostraram que houve diminuição do índice de massa corporal, da circunferência abdominal e do percentual de gordura; aumento de 18% do consumo máximo de oxigênio predito (pré: 48,8 ± 4,6 ml·kg·min-1; pós: 57,3 ± 3,8 ml·kg·min-1) e diminuição da potência anaeróbia máxima (pré: 523,3 ± 181,8 W; pós: 448,7 ± 140,3W) e potência anaeróbia média (pré: 412,6 ± 121,7W; pós: 344,7 ± 66,7W). Assim, apesar do treinamento ter melhorado aspectos relacionados à composição corporal e aptidão aeróbia, não se mostrou efetivo na melhora da potência anaeróbia, não garantindo um nível ótimo de aptidão física para a realização das tarefas relacionadas à profissão de bombeiro.

Abstract: The aim of the study was to verify the effect of the compulsory physical training provided by the firefighters' corporation on the fitness level and body composition to newly recruited firefighters. Forty- six male firefighters newly recruited (23.9 ± 2.9 years), were assessed based on their aerobic fitness (12-minute test of Cooper), anaerobic power (Running-based anaerobic sprint test – RAST), anthropometric (Weight, height and abdominal circumference) and body composition (fat percentage) pre and post a compulsory training program of 27 weeks, under the guidance of firefighters' corporation members. The normality of data distribution was verified by the Shapiro-Wilk test, and the variables were compared according to moments of evaluation by Student’s t test for paired samples, it was also checked the percentage differences and effect size of the variables in pre and post-training moments; the level of significance was set at P < 0.05. The main results showed that there was a decrease in body mass index, abdominal circumference and fat percentage; an increase of 18% of predicted maximum oxygen consumption (pre: 48.8 ± 4.6 ml·kg·min-1; post: 57.3 ± 3.8 ml·kg·min-1) and decrease of maximal anaerobic power (pre: 523.3 ± 181.8 W; post: 448.7 ± 140.3W) and average anaerobic power (pre: 412.6 ± 121.7W; post: 344.7 ± 66.7W). Despite the training has improved some aspects related to body composition and aerobic fitness, it was not effective in improving anaerobic power, not ensuring optimal level of fitness for firefighters to perform tasks related to their profession.
