Resumo: A composição corporal (CC) é um componente crucial no acompanhamento de atletas, não apenas como variável relacionada ao desempenho físico, mas também como acompanhamento da intervenção dietética e do treinamento. Objetivo: Propor equações de regressão da área de superfície corporal (ASC) para estimar a massa livre de gordura (MLG) de guias de montanha e carregadores utilizando a diluição com óxido de deutério (MDD) como método critério. Métodos: Estudo transversal com 23 homens jovens e adultos que trabalham como guias de montanha e carregadores no Aconcágua (Argentina). Os voluntários tinham idades entre 20 e 50 anos. Peso, altura, índice de massa corporal (IMC) e ASC foram avaliados por oito equações de regressão. Resultados: Foram geradas três equações de regressão linear considerando idade cronológica e ASC como preditores: Modelo 1 (FFM = - 25,287 - (0,260 * idade) + (49,014 * ASC1), R2 = 63,0%), modelo 2 (FFM = -20,736 - (0,191 * idade) + (45,523 * ASC2), R2 = 62,0%) e modelo 3 (FFM = -28,592 - (0,244 * idade) + (52,499 * ASC3), R2 = 63,0). Conclusão: Foram gerados três modelos preditivos baseados em idade e ASC que permitem estimar a MLG de forma válida e confiável. Os resultados sugerem seu uso e aplicação para monitoramento antes, durante e após expedições.
