摘要：We investigated the effect of long slow distance training on aerobic work capacity in eleven 2-year-old Thoroughbred horses. Eight weeks of training (5 days/week) was performed on a track at a slow canter, 6 horses were cantered 3, 200 m for 3 weeks, and then increased to 4, 800 m for 5 weeks (Group L), while the other 5 horses were cantered 800 m throughout the same training period (Group S). Each horse performed an incremental exercise test on a treadmill before (Pre-test) and after (Post-test) the training period. In the Pre-test, there were no significant difference between Group L and Group S regarding Vo₂Peak (152.6 ± 13.2 ml/kg/min in Group L vs 149.9 ± 17.1 ml/kg/min in Group S) or the slope of the regression line for Vo₂ and running speed. Peak heart rates (HRpeak; 221.8 ± 6. 7 beats/min in Group L vs 225.6 ± 7. 7 beats/min in Group S), and peak blood lactate concentrations (LA peak; 1 4.4 ± 3.3 mmol/l in Group L vs 13.0 ± 3.5 mmol/l in Group S) were not significantly different between the two groups. In the Post-test, there were no significant differences between groups in Vo₂peak (156.1 ± 11.5 ml/kg/min vs 152.6 ± 5.4 ml/kg/min in Groups L and S, respectively), slope for Vo₂ and speed, HRpeak (224.0 ± 6.4 beats/min vs 227.2 ± 6.8 beats/min in Group L and Group S, respectively), or LApeak (15.2 ± 3.2 mmol/l in Group L vs 13.6 ± 3.1 mmol/l in Group S). These results indicate that, in the case of low intensity cantering of 8-week training, differences in training distance do not significantly affect the degree of improvement in aerobic work capacity in the young Thoroughbred horse.
