Characteristics of changes in muscle tone and cardiovascular system during exercises, based on performing aerobic mode and differential learning tasks

Aim of the work: to determine the characteristics of changes in muscle tone and cardiovascular system, while performing aerobic exercise mode and differential learning based tasks. Objectives of the work: 1. To determine, whether there is a tendency for muscle tone indicators to decrease, while performing aerobic exercise mode and aerobic DL – based exercises using veloergometer. 2. To determine, whether the dynamic interactions between ECG indicators makes stronger relations between, while performing aerobic exercise mode and aerobic DL – based exercises using veloergometer. Methods: The study involved 6 physically active women / girls aged 21.67 ± 0.52 years. Each women performed in 2 studies: 1) an aerobic exercise load on a veloergometer, performing differential learning tasks; 2) Aerobic exercise load. In both studies, the computerized electrocardiogram analysis system \"Kaunas-Krūvis\", developed by the LSMU Institute of Cardiology, was used to evaluate the functional status of the cardiovascular system, and the Myoton3 device was used to measure the muscle tone. In the study of the relationship between the RR interval of the two electrocardiogram parameters and the QRS change duration, the method of evaluation of dynamic interfaces created by Lithuanian scientists was used. The reliability of the results was evaluated based on the student – t test. The differences were considered to be reliable when p
