Table 2 Outcome measures for model identification at two intensity levels: \(v_1\) (moderate) and \(v_2\) (vigorous); p values for comparison of means for k and \(\tau\)

From: Identification of heart rate dynamics during moderate-to-vigorous treadmill exercise

  Exercise intensity p value
\(v_1\) (moderate) \(v_2\) (vigorous)
\(P_o\) \(24.3/(55.7\;s + 1)\) \(24.1/(59.5\;s + 1)\)  
k [bpm/(m/s)] 24.3 ± 9.2, 20.7–28.0 24.1 ± 7.6, 21.1–27.1 0.88 (n.s.)
\(\tau\) (s) 55.7 ± 29.9, 43.8–67.7 59.5 ± 15.2, 53.4–65.6 0.53 (n.s.)
Fit (%) 49.6 ± 11.1 54.7 ± 14.2  
RMSE (bpm) 2.8 ± 0.7 2.5 ± 1.1  
  1. Values for k and \(\tau\) are: mean \(\pm\) standard deviation, 95 % confidence interval for the mean
  2. Values for fit and RMSE are: mean \(\pm\) standard deviation
  3. \(n =24\)
  4. p values are for paired two-sided t tests
  5. RMSE root-mean-square error, bpm beats per minute, n.s. not significant
