Abstract |
In human sports medicine exercise tests are normally used to check training progression. Correlation tests between blood lactate concentration and exercise speed are often used for this purpose. Studies have been done to adjust exercise tests for athletic horses using the same principle. The aim of this work was to verify the practical possibility that the anaerobic threshold in elite endurance horses could be calculated by adjusting a submaximal exercise field test in order to obtain reference parameters for endurance horses. Ten selected horses from the Italian National Endurance Team were used for this study. The tests were conducted on an 800 meters grass oval. Horses performed three steps (800 meters every step), at increasing speed with two minute intervals between each step. Riders were informed of the ideal speed for every step (5, 7.5, 10 m/s) and the real velocity was calculated on the basis of time taken to finish a single step. Blood samples were obtained via venipuncture from the jugular vein, immediately before the beginning of the test and 60 seconds after the end of each step. The following parameters were evaluated for each horse: individual anaerobic threshold (VSI), anaerobic threshold (V4) and exercise velocity corresponding to a lactate concentration of 2 mM/I (V2). Analysis of results indicate that lactate concentration is exponentially related to exercise speed for the entire test. VSI, V4, V2, were (mearttsd): 25.7±5.1; 30.5±2.5; 21.1±2.9 km/h respectively. |

Abstract |
Endurance horses, like marathon runners, undertake sub-maximal, longterm physical exercises and in both cases thermoregulation plays a critical role. A standardised sub-maximal treadmill test was used to assess fitness and training state in endurance horses. Literature reports that trained human athletes dissipate head load better than not trained ones; in this study parameters related to thermoregulation were recorded together with other haematologic and metabolic ones. Six endurance horses, divided into two groups according to their training state, performed two submaximal tests at a distance of one week. Blood samples were collected at rest, during exercise, at the end and during recovery (10, 30 and 60 minutes after work). Heart rate (HR), respiratory rate (RR), rectal (RT) and skin (ST) temperatures were monitored through the exercise (and recovery for HR). HR resulted significantly lower (P<0.01) in trained horses than in untrained ones, especially during recovery. Also rectal and skin temperatures resulted significantly lower (P<0.05) in trained horses and ST increased more gradually during exercise. The values of haematocrit and haemoglobin resulted significantly lower (P<0.05) at rest, during exercise and recovery samples. In this study, the parameters related to thermoregulation, in accordance with data from human athletes, resulted significantly different in trained and untrained horses, while other parameters didn't vary significantly between the two groups. Thermoregulatory responses to exercise-generated heat load in a standardised test, studied by simple parameters, can thus offer useful information about fitness and training state of endurance horses. |
