“…There are a number of more recent papers that describe, for example, monitoring lactate-speed relationships and v 200 for assessment of performance enhancement, although the descriptions of the conditioning regimes are lacking (Mohr et al 1999;Kobayashi et al 1999).…”

SummaryBlood lactate measurements are used widely in horses to assess athletic performance, but there are few published data on using lactate as a guide for endurance improvement. The velocity at which blood lactate concentration ([LA]) of 4 mmol/l is reached (v 4 ) is widely used to determine fitness. In an earlier study of v 4 , exercise at low intensities for longer duration was more effective at improving endurance than shorter, higher intensities. However, the prescription was unchanged during the study (6 weeks). We hypothesised that, to produce greater improvement in v 4 in the same time frame, it is necessary to adjust conditioning regimes more frequently. Six horses underwent an initial treadmill-based standard exercise test (SET). A regression analysis [LA]-speed relationship was used to calculate v 2 . Horses were then conditioned for 45 min at their calculated v 2 3 times/week (6% incline). Every 2 weeks the horses performed an SET to evaluate the v 2 conditioning protocol which ended with SET 4. Mean v 4 increased 17% from SET 1 to SET 4 (P = 0.003; 5.8 ± 0.3 to 6.8 ± 0.4 m/s). This study demonstrates that a lactate-guided conditioning programme can significantly enhance endurance performance over a 6-week time peroid when the conditioning protocol is adjusted every 2 weeks based on v 4 improvement.

“…Note the pronounced increase in heart rates when trotting at 250 m/min in an excited condition. 17 However, the mean V200 was 35 m/min higher with light jockeys, and it seems sensible to avoid large differences in fi eld studies of ridden horses. ( If there is some doubt concerning the results in an individual exercise test, the test should be repeated.…”

“…Blood samples can be collected during rest periods after each step of the exercise test. 17 Commercial heart rate meters that log heart rate continuously and enable transfer of the data to a computer for analysis are suitable for this purpose. 16 In this exercise test, each horse was exercised over a 450 m distance at speeds of approximately 250, 300, 450, and 600 m/min.…”
