Reference Values for Cardiorespiratory Fitness in Healthy Koreans

  Figure 1. Nomogram of the percentage of predicted exercise capacity for age in healthy Korean participants. When a line connecting the subject’s age (on the left scale) and the metabolic equivalents (METS) value (on the right scale) is drawn, that line intersects the percentage line. The intersection point is the percentage of predicted exercise capacity for age. The red line is the women’s percentage line and the blue line is the male’s one.

  Figure 2. Comparison of cardiorespiratory fitness (CRF) of men (A) and women (B) between recent Korea, US, Norway, and Denmark. VO2max, maximal oxygen uptake (mL/kg/min). * CRF of Danish cohort was measured by cycle ergometer with the maximal power output (MPO) protocol. Due to the difference in VO2max from exercise test methods, for simple comparison, the VO2max measured by the cycle ergometer was multiplied by 1.15 times. The original VO2max values of the Danish cohort can be found in Table S1.

  Figure 3. Comparison of cardiorespiratory fitness (CRF) between past and recent cohort. (A) Past and recent Korean men; (B) Past and recent US Men; (C) Past and recent US women. VO2max, maximal oxygen uptake (mL/kg/min). * CRF of past Korean participants was measured directly by cycle ergometer with gas analysis. Due to the difference in VO2max from the exercise test methods, the VO2max measured by cycle ergometer was multiplied by 1.15 for a more simple comparison. The original VO2max values of past Korean participants can be found in Table S1.
