The vital point of the Parameters of Morpho-functional State of Gymnasts for the Assessment of Physical Development at the Stage of Sports Perfection

The article presents the data of the assessment of the physical development and functional state of highly qualified gymnasts engaged in rhythmic gymnastics. It was found that high-skilled gymnasts have heterogeneity of somatotypes determined according to the B. Heath-J. Carter scheme and heterogeneity of types of autonomous nervous regulation of heart rate variability, systolic, diastolic blood pressure and respiration, determined on the spiroarteriorhythmocardiograph device. Highly qualified gymnasts have vago- and normotonic types of regulation of heart rate variability; normal-sympathetic- and hypersympathicotonic types of regulation of the variability of systolic blood pressure and diastolic blood pressure, vagotonic type of regulation of the variability of the respiratory rhythm. Statistically significant differences gymnasts, successful in the medal standings at the international competitions and gymnasts participating, but not in high prizes in competitions, consist in the ability to resist fatigue while performing strenuous mental work (differences were revealed in 10-letter “Mental performance” at a constant speed (p > 0.0001), and 3-letter test (p > 0.001)), data stabilometric test “Target” indicator “Time stability on the left foot” (R > 0.039) with the advantage of a high performing gymnasts artists. Fleshed out the possibility of using the parameters of the morphofunctional state of gymnasts in training for the qualitative evaluation of the physical development of gymnasts, evaluation set their sports uniforms indicated the possibility of developing the reference parameters of the morphofunctional status of gymnasts and recommendations on the frequency of the survey of morphological and functional status of gymnasts involved in rhythmic gymnastics.
