  1. This table shows the mean ± standard deviation. “a-1”, “b-1”, “c-1” lists the measured values (raw data) and “a-2”, “b-2”, “c-2” lists the values normalized by the height of each subject. Significant differences between the two groups are indicated by one or two asterisks (*p < 0.05, **p < 0.01)
