Dynamics of cardiovascular indices during the 24 hours and exercise training session in aerobics SUMMARY Objects: The aim of this study was to assess the peculiarities in functioning of cardiovascular system during 24 hours and aerobic exercise session. Goals: 1) to monitor the functioning of cardiovascular system during 24 hours. 2) to assess the dynamic of ECG parameters during 24 hours and aerobic exercise. 3) to compare the variability of ECG parameters during 24 hours and aerobic exercise sessions. 4) to assess the distribution of ECG parameters during 24 hours and aerobic exercise. Research contingent: The participants in this study were 29 voluntary students (age of 22,6±0,43) who attended healthiness aerobic exercise club for 2-3 times per week Methods: The computerized system “Cardio Scout” designed for registration and analysis of 5 lead ECG was used for this purpose. The questionnaire for all participants was presented. Results: The values of JT interval and ST-segment depression during the highest intensity phase of exercise session increased significantly and was different in mobilization and recovery phases (p<0.05). We found-out that values of hart rate (HR) was the lowest and JT intervals was the longer during 24 hours monitoring (p<0.0001). During the exercise HR was higher than during the all time of 24 hours monitoring. The amplitude of R wave of ECG during 24 hours was completely the same and ST-segment depression was similar (p>0.05). Statistically... [to full text]
