Abstract Objective To observe the effect of prolonged high load military training on lymphocyte subsets in soldiers of Chinese Armed Police Forces and to provide data for scientific training protocols. Methods Twenty-three soldiers participated in three-day military training, whose lymphocyte subsets, plasma testosterone, cortisol and upper respiratory tract infection symptoms were determined before training (the first morning), during training (the second morning) and after training (the fourth morning) respectively. Results Compared with pre-training, CD3+T increased significantly (P0.05). The incidence of upper respiratory tract infection was 17.4% during training. CD3+T (P<0.01), CD4+T (P<0.01), CD8+T (P<0.01), CD4+/CD8+ ratio (P<0.05), CD16+T (P<0.01) and plasma testosterone (P<0.01) decreased significantly while plasma cortisol rose notably (P<0.01) and the incidence of upper respiratory tract infection was 65.2% after training. Conclusions The training load on the first day was adequate and apparent immunosuppression appeared after three-day training, which is related to exercise-induced low blood testosterone and high cortisol.
