The changes of heart rhythm variability among the students-sportsmen with different training process direction with long mental loading

摘要

The heart rhythm variability was investigated among the students-sportsmen with different training process direction for the development of endurance and strength under the influence of mental loading. Some differences were found in the work of cardio-vascular system among the sportsmen of two groups. They were shown both at rest and with loading, and were stipulated by the changes appeared under the influence of systematic physical loading. It is proven that in a state of rest sitting students with the power orientation of training process by comparison with the students that are not sportsmen has a greater level of heart rhythm variability.
