| Values | ICA | ECA | Difference between Means | P Value |
|---|---|---|---|---|
| BF (mL/100 g/min) | 89.25 ± 34.42 | 90.93 ± 43.94 | −1.67 ± 15.17 | .7221 |
| BV (mL/100 g) | 4.07 ± 1.46 | 4.38 ± 1.78 | −0.31 ± 0.46 | .0488 |
| MTT (s) | 4.03 ± 1.36 | 4.26 ± 1.19 | −0.23 ± 0.72 | .3190 |
| Capillary PS (mL/100 g/min) | 27.68 ± 6.25 | 26.74 ± 5.45 | 0.94 ± 4.12 | .4676 |
