Results of comparative assessment of level of harmonicity of development in Ketle index and the Pinye index in three groups of the young athletes having a different experience of occupations sports dances are provided. The key morphological indicators were measured: body length, body weight, a thorax grasp in three groups of dancers. Each group consisted of 10 people (5 young men and 5 girls). For assessment of harmonicity of development used two indexes - weight-growth and chest and growth. The comparative analysis of index estimates in three groups of the dancers having a different experience of occupations sports dances is carried out. The value of the index of Ketle and the Pinye index at young men of the first and second groups indicates their low nutritsionny status and harmonicity physical development. At young men of the third group the value of these indexes is optimum or above an average that indicates harmonicity or hyper harmonicity physical development. Differences by indexes of harmonicity of physical development between groups of girls insignificantly. The conducted research showed that athletes with the maximum experience of occupations sports dances, have significant distinctions on all morphological indicators in comparison with athletes with a smaller experience of occupations. Occupations sports dances depending on an experience promote at the young men who are in the teenage and youthful period of development of harmonicity of physical development. For girls passing through the same age and being in the youthful period of development sports dances promote maintenance of harmonious of physical development.
