The article presents the results indicating that biological age determines the specificity of physical fitness and working capacity of adolescents. It has been shown that teenage boys 13-14 years old with different stages of puberty differ significantly in terms of physical performance and fitness. In the course of the study, it was found that adolescents of the same calendar age with stages II and III of puberty do not have significant differences in terms of the studied indicators, which allows us to assert a certain similarity between boys of these stages in terms of physical fitness and working capacity. The results obtained must be taken into account to increase the efficiency of the process of physical education of adolescents and to ensure a rational dosage of the applied physical loads in accordance with the functional capabilities of the trainees, based on the characteristics of their biological age.
