Objective of the study was to identify the levels of physical development and physical fitness of the 18-25 year-old students trained in different climatic geographic conditions.
Methods and structure of the study. The body component composition was determined using the impedance method. The level of physical development was evaluated based on the generally accepted parameters. The physical fitness rates were determined in the "field" tests.
Results of the study. The study showed that it is the Africans who have the greatest tension of chronoadaptation. They differ by the statistically significantly low body mass rates, low free and visceral fat mass rates, and high free water contents. Their physical development is characterized by the statistically low rates of body length, wrist dynamometry, chest circumferences at inhalation and exhalation, as well as low strength rates of physique with regard to EI. As opposed to the Slavs and Asians, the Africans have the weakest strength, speed-strength and coordination abilities. The Asians are distinguished by the significantly high muscle mass rates, visceral fat mass rates, and EI. The Slavs have the highest rates in terms of body length, free fat contents, left and right hand dynamometry, EI, as well as the strongest strength, speed-strength and coordination abilities.
Conclusion. In the Slavs and Asians, the average body mass rate does not differ statistically significantly. Secular changes in the somatic status of young males residing in different areas vary due to the effects of environmental factors.

Keywords: ethnic group, students' body composition, physical development, physical fitness.
