A sample of 37 volleyball players of younger cadets from the region of Dalmatia conducted a study to determine differences in biological and chronological age and some motor skills between younger cadets who live and train in rural areas (Posedarje) and those who live and train in urban areas (Split). In Split, 20 younger cadets who train and compete in the club "Split Volley Team" were tested. In OK Posedarje, 17 younger cadets who train and participate in competitions at the local level were tested. Some of the anthropometric characteristics, body height, sitting height and body weight were measured, and on the basis of these characteristics the biological age indicator was calculated, ie on the basis of the calculation of the age of maximum growth in height (PHV) according to the method of Mirwald, Baxter- Jones, Bailey, & Beunen (2002). Furthermore, tests were conducted to assess explosive power and agility. The subjects were measured in the long jump test, high jump from the spot, high jump after the volleyball run, 9-3-6-3-9 test and the steps aside. Younger cadets from Split achieved significantly better results in tests to assess the explosive strength of the legs and non-specific agility. Given that a statistically significant difference exists only in some motor abilities, we can conclude that both groups have a similar functional and anthropometric basis for training, competition, and progress. Therefore, we can assume that their readiness and success depend on the environment in which they live and train, on training age, on how to spend free time, on the quality of the training process, on the level of children's interest in volleyball (number of children training) and later on selections.
