This study aimed to investigate the gender difference in the manifestation of physical stress in a strenuous military training on Amazon jungle, using alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LDH) markers, measured before and after an adaptation to jungle training. The sample consisted of 49 military volunteers, 35 male and 14 female, recently moved to the Amazon region. All plasma levels rose after the training. Serum ALT (male and female) and AST (male and female), although borderline, remained within normal limits. Already plasma levels of CK (both male and female) and LDH (male and female) largely exceeded the normal range. The average of all markers listed in female gender remained below the levels of the male gender. However, significant differences in biomarkers ALT, AST and CK between genders were found. The study points out that, in a jungle environment, biometric markers ALT, AST, CK and LDH are efficient for monitoring chronic physical stress in both genders, when used in combination. The influence of the weather on the occurrence of physical stress in unacclimated people of both genders, and the lower responses in the levels of ALT, AST, LDH and CK in females were discussed basing on the scientific literature.
