[Abstract]:Objective: to study the correlation between heart rate variability (HRV) and cardiovascular function in the Harvard step test and 30 squat up test in 30 seconds. The effectiveness of heart rate variability in measuring cardiovascular function is higher than that in 30 seconds squat up experiments, which provides a theoretical and practical reference for the real-time prediction of possible exercise risk and sudden death during exercise. Methods: 32 subjects who met the requirements of the experiment were divided into youth group and middle age group according to the latest age classification standard of WHO. The simple and feasible Harvard step test for measuring cardiovascular function index and the 30 squat up test for 30 seconds were used to measure heart rate, blood pressure and step index. The study focused on ECG signals with heart rate variability, which were recorded synchronously in 30 squats in 30 seconds and 3 minutes in the Harvard step test. At the end of the experiment, the data were statistically analyzed. Results: the correlation coefficient between heart function index and step index in young group was -0.656, and the coefficient of heart rate variability was 120-180 seconds.) the correlation coefficient between heart function index and step index was -0.837, and the correlation coefficient between heart function index and step index was -0.837, the correlation coefficient between heart function index and step index was -0.837. The correlation coefficient between the HRV and the step index was -0.754 ~ P0. 001g ~ (2).) the Harvard step test was used as the effective standard. The experimental results of measuring validity: the rank correlation coefficient between cardiac work index and step index in young group was -0.603 ~ 0.013 渭 m, and the coefficient of heart rate variability was 120-180 seconds) and the rank correlation coefficient between heart function index and step index was -0.96 ~ 0.000, and that between heart function index and step index in middle age group was -0.96. The correlation coefficient was-0. 590 ~ 0. 016 ~ 0. 016 渭 m, and the coefficient of heart rate variability was 120-180 seconds) and the rank correlation coefficient of step index was -0. 897 and 0. 008% respectively. The results showed that the correlation between the coefficient of heart rate variability and the step index was higher in the young group and the middle age group than in the heart function index and the step index. Conclusion (1) there is a correlation between the coefficient of heart rate variability and the cardiovascular function level expressed by the cardiac work index and step index, both in the young group and in the middle age group. The correlation between heart rate variability and step index was higher than that between heart function index and step index, which indicated that the use of heart rate variability index to measure cardiovascular function was supported by the experimental results. Is of theoretical and practical significance.) whether in the youth group or the middle age group, the Harvard step test is used as the effective standard. Using heart rate variability to measure cardiovascular function was more effective than using 30 squats in 30 seconds to measure cardiovascular function. It shows that real-time heart rate variability in exercise can meet the practical requirements.
