Results of Thrombelastometry (ROTEM®) and impedance aggregometry (Multiplate®) before and after competition
| Marathon | Triathlon | Cycling | p(ANOVA) | |
|---|---|---|---|---|

| CT INTEM after (s) | 155 ± 18.3 # | 154.2 ± 11.3 # | 152.5 ± 13.0 # | 0.9255 |
| MCF INTEM before (mm) | 58.1 ± 3.9 | 56.1 ± 3.2 | 59.3 ± 5.0 | 0.0823 |
| MCF INTEM after (mm) | 62.4 ± 3.8 # | 59.5 ± 3.1 # | 64.2 ± 4.2 # | 0.0013 * |
| MCF FIBTEM before (mm) | 10.9 ± 2.7 | 8.9 ± 2.8 | 9.6 ± 3 | 0.0928 |
| MCF FIBTEM after (mm) | 12.5 ± 3 # | 9.9 ± 2.4 # | 11.3 ± 2.4 # | 0.0136 * |
| Multiplate® impedance aggregometry results | ||||
| AUC TRAP activation before (g/l) | 899 ± 149 | 911 ± 233 | 970 ± 186 | 0.4672 |
| AUC TRAP activation after (g/l) | 1041 ± 209 # | 1009 ± 315 | 906 ± 288 | 0.3492 |
| AUC ADP activation before (g/l) | 529 ± 174 | 508 ± 178 | 589 ± 160 | 0.1281 |
| AUC ADP activation after (g/l) | 795 ± 258 # | 800 ± 320 # | 627 ± 219 | 0.0865 |
Data are displayed as mean ± standard deviation. (p < 0.05) Note, that results, obtained by thrombelastometry, show a significant increase of clot stability and shortening of coagulation times, while platelet aggregation is increased only in MAR and TRI after ADP activation, respectively in MAR after TRAP activation, but not in CYC.
