Physiological Parameters of Endurance Horses Pre- Compared to Post-Race, Correlated with Performance: A Two Race Study from Scandinavia
Table 3
(a) Plasma values for horses in race A taken before and after a 120 km race. Values are presented as mean ± s.d. or median [Q1. Q3]. (b) Plasma values for horses in race B taken before (8–12 hrs) and after the race (average of 3 hrs and 48 mins and 24 hrs, respectively). Values are presented as mean ± s.d.
