  1. Values are mean ± SD, median with IQR (25th – 75th percentiles), or absolute number (%).
  2. * Logarithmic transformation was done for these variables due to skewed distribution.
  3. † ΔFMD = post-exercise FMD (%) – pre-exercise FMD (%).
  4. ‡ Maximum HR (%) = percentage of age-predicted maximum heart rate.
  5. BPM = beat per minute; DBP = diastolic blood pressure; HR = heart rate; IQR = interquartile range; METS = metabolic equivalents; SBP = systolic blood pressure.
