Observed hemostatic activation post hot ultra-cycling may signal transient risk in vulnerable athletes; leaves open clinical relevance pending outcome studies.
Does completing a 164-km road cycling event in a hot environment alter blood hemostatic markers?
Ultraendurance cycling in a hot environment increases both coagulation and fibrinolytic markers, suggesting a balanced hemostatic response that may prevent clot formation.
Kupchak et al. (2017) studied this question.
