Scatter plot of %VO2R versus %HRR, %VO2R versus MA, %VO2R versus MSD, and %VO2R versus RMS. The scatter plots of acceleration indices: %VO2R versus %HRR (A: r = 0.97, P < 0.01), %VO2R versus MA (B: r = 0.87, P < 0.01), %VO2R versus MSD (C: r = 0.96, P < 0.01), and %VO2R versus RMS (D: r = 0.92, P < 0.01)
