  1. Individuals with three or more of metabolic syndrome risk factors (i.e.., central obesity, hypertension, hyperglyceridemia, hypertriglyceridemia, and low HDL-C) were coded for analyses as having the metabolic syndrome (Mets)
  2. BP blood pressure, HDL-C high-density lipoprotein cholesterol, eCRF non-exercise-based estimation of cardiorespiratory fitness, HOMA homeostatic model assessment of insulin resistance
  3. aSignificant difference between individuals with and without metabolic syndrome (p < 0.001)
