Introduction. Modern types of fitness technologies due to their availability for their implementation into the process of physical education of students create wide opportunities for improving the functional state of the organism. A popular direction of health fitness is yoga with a psycho-regulatory function, which allows influencing the state of the cardiovascular system. Purpose: to indicate the effect of yoga classes on the state of the cardiovascular system of 17-18 years old girls.
Materials and Methods. 161 student girls of the first year of study took part in the experiment, who were divided into 2 homogeneous groups of research subjects: control group (CG) – 79 girls attending physical training classes under the traditional curriculum; experimental group (EG) – 82 girls who were invited to attend yoga classes. Practical classes involved studying and performing asanas of classical complexes «Surya Namaskar» («Sun Salutation») and «Chandra Namaskar» («Moon Salutation»).
Results. Following the experiment, no statistically significant changes were found in the girls in the control CG (p ≥ 0.05). The EG students showed improvements in all studied cardiovascular system parameters. A decrease in HR (from 75±0.31 to 69±0.48 bpm, p≤0.05) indicated a prolongation of the cardiac cycle duration as a result of increased vagal activity. A decrease in blood pressure (p ≤ 0.05) and an increase in CO (from 50 ± 0.76 to 56 ± 0.62 ml, min, p≤0.05) and CO (from 3.4±0.48 to 3.8±0.23 L/min, p≤0.05) in the EG indicated improved vascular tone, increased myocardial contractility, and enhanced CO. Among female students in the CG, integrative indicators (Robinson and Rufier indices, AP) showed a tendency toward deterioration (p ≥ 0.05). Under the influence of the experimental methodology in the EG, changes in the Robinson index (from 91.1±1.54 to 88.4±1.40 conventional units, p≤0.05), AP (from 2.42±0.51 to 2.08±0.38 conventional units, p≤0.05) and the Rufier index (from 7.8±0.91 to 6.5±0.64 units, p≤0.05) in the EG indicated an improvement in systolic cardiac function, physical performance, and an optimal state of the body’s functional reserves.
Conclusions. The study results demonstrated the positive impact of fitness, incorporating the «Surya Namaskar» and «Chandra Namaskar» asana sequences accompanied by relaxing music and mantras, on the functional state of the cardiovascular system in 17- to 18-year-old girls. This allows us to recommend the use of yoga practices to improve and maintain the health of college students.
