Table 1.
Morphological characteristics, training status and best race time in the half-ironman distance for the participants in this investigation.
Table 2.
Changes in serum variables before (pre) and after (post) a half-ironman race.
Fig 1.
A) Relationship between race time and sector times (swimming, cycling and running) and post-race tryptophan/BCAA ratio during a half-ironman race. B) Relationship between post-race creatine kinase concentration and changes of BCAA concentration during a half-ironman race (as a change from pre-exercise values).
Note: A) The correlation of total race time (r = -0.05; P = 0.80), swimming time (r = -0.05; P = 0.80), cycling time (r = 0.08; P = 0.70) and running time (r = -0.21; P = 0.30) with post-race tryptophan/BCAA ratio were not statistically significant. B) The correlation of post-race creatine kinase concentration with BCAA change during the race (r = -0.02; P = 0.92) was not statistically significant.
