Features of physical development, largely determine the possibility of achieving high sports results in various sports. The study of morphofunctional indicators of athletes of different specializations has long been one of the important areas of sports science. It is known that athletes of different specializations are distinguished by characteristic morphofunctional signs and types of biological development that determine the growth rate of sports achievements. However, a comparison of the physique and physical development of girls involved in swimming and diving has not previously been carried out. The article presents a comparison of morphofunctional indicators of girls of 11-12 years of age, engaged in swimming and diving, pupils of the SSR of Moscow. Research methods: anthropometry, fractionation of body weight, methods of statistical data processing. The differences in physical development and the composition of the body weight of girls jumpers in the water and swim 11-12 years. So girls swimmers have higher rates of length and body weight, as well as chest girth, and jumpers in the water – the advantage of active body weight. The study revealed differences in the physical development of girls involved in swimming and diving from the age of 11. These differences seem to be due to the influence of sports selection, on the one hand, and on the other –sports training. Keywords—swimmers; water jumpers; physical development; body proportions; body mass composition.
