Figure 2: (a and b) The data from naïve and experienced subjects, respectively. Upper row: Changes in heart rate (HR) and heart rate variability parameters (high-frequency HF, low-frequency LF, low-frequency/high-frequency LF/HF, and low-frequency + high-frequency LF+HF) at the resting state after yoga (post) in comparison with that of before yoga (pre). The data from the same participant are connected by a line. No statistically significant differences are observed between the data before and after yoga (Wilcoxon signed-rank test, P > 0.05). Lower row: The low-frequency and low-frequency/high-frequency scores at the resting state before yoga (pre) plotted against the changes in these scores after yoga (post/pre). For these two parameters, “post/pre” scores show a correlation with “pre” scores (Spearman's correlation coefficients, P < 0.05). When the scores are high before yoga (pre), they tend to decrease, and when low, they tend to increase after yoga, presenting “normalization effect”
