PHYSIOLOGICAL-HYGIENIC CHARACTERISTICS OF ADAPTIVE RESERVES OF THE BODY OF SINGERS WITH VOCAL ABILITIES, AND POTENTIAL WITHOUT
The article describes the physiological and hygienic characteristics of adaptive reserves of the body of singers with potential abilities and without them on the basis of the dynamics of changes in the indices of autonomic status, functional reserves and biological adaptation. In the dynamics of learning in a group of singers with vocal abilities, potential, an increase in the percentage of students with vagotonia 4 %; a slight decrease vocalists with satisfactory adaptation and stress adaptation mechanisms; a slight increase vocalists with reduced functionality. In the group of vocalists potential without vocal abilities in the dynamics of learning marked increase in the index of regulatory systems tension alone is 2.3 times; an increase in the percentage of students with a sympathetic tone 12.3 %; the increase vocalists with unsatisfactory adaptation by 6% and vocalists with the breakdown of adaptation 2.1 %; reducing singers with sufficient functional reserves of 8.7% due to the increase of vocalists with reduced and significantly reduced functional reserves.
