Currently it remains urgent to study the influence of central regulatory mechanisms on processes of adaptation to training loads in those engaged in physical culture. Rate is an important factor in the work involving such mechanisms. System of rhythm and tempo accompaniment of aerobics classes affects both body's psychological state, and physiological parameters. The purpose of the study was to analyze the effect of various rhythm and tempo structure of aerobics classes on psychophysiological characteristics of female students' body. The increase of the rhythm and tempo accompaniment of aerobics classes to 140 bpm results in the reduced strength and mobility of nervous processes, indicating the reduced psychophysiological adaptability that characterizes efficiency of actions and optimal performance. At the same time, in case of the rhythm and tempo accompaniment of the class of 140-160 bpm an increase in the strength of nervous processes, in muscle strength and endurance is observed, the increased rhythm and tempo accompainment of classes from 115-125 to 125-140 bpm leads to motor coordination disturbance. Further rise in the rate up to 140-160 bpm increases the accuracy of movements. All the above indicates that adaptive adjustments when changing the rhythm and tempo structure of load are of phased nature. Along with fatigue being developed with the increase of the tempo of the class, when the tempo is over 140 bpm, central regulatory mechanisms get involved in the process, that provide adaptation to loads, which is shown in stronger and better coordination of movements, as well as changes in the structure of motor asymmetries.
