Field-training in young two-year-old thoroughbreds: investigating cardiorespiratory adaptations and the presence of exercise induced pulmonary hemorrhage

Table 3 Data from 10 young two-year-old Thoroughbred horses undergoing introductory track-based training. Post-exercise whole blood hematocrit (HCt, %), plasma ammonia (NH_3, μmol/L) and blood lactate (mmol/L) between the early-training (week 4) HSET and late-training (week 12) HSET. Values presented as mean ± SD

n = 10	Early-Training	Late-Training	% Change	P Value

Post-exercise NH₃ (μmol/L)	59.0 ± 15.4	76.3 ± 32.4	+ 29.3%	0.03
Post-exercise blood lactate (mmol/L)	9.1 ± 3.5	13.5 ± 5.0	+ 48.4%	0.001
