Abstract
The effect of lactate minimum speed (LMS)-guided training on horses' homeostasis is still unknown. Thus, this study aimed to evaluate the effect of an LMS-guided training program on the fluid, electrolyte and acid-base status of horses. Ten untrained Arabian horses were submitted to an LMS test on a treadmill before and after six weeks of training. The training intensity was 80% of the LMS in the first three sessions and 100% of the LMS in the other sessions. The venous blood was collected before (T-1) and after (T-2) training at rest, during and after the LMS test for lactate, pH, pCO2, HCO3-, and electrolyte measurements. The LMS and strong ion difference (SID4) were calculated. A mild increase in the mean values (p > 0.05) was observed at rest in T-2 in comparison with T-1 in the following variables: pH (from 7.436 ± 0.013 to 7.460 ± 0.012), pCO2 (from 42.95 ± 1.58 to 45.06 ± 0.81 mmHg), HCO3- (from 27.01 ± 1.02 to 28.91 ± 0.86 mmol/L), and SID4 (from 33.42 ± 1.45 to 35.06 ± 2.94 mmol/L). During T-2, these variables were more stable than during T-1. Despite the improvement in fitness, the LMS did not indicate a significant difference (from 5.40 ± 0.55 to 5.52 ± 0.20 m/s). The results confirmed that the LMS-guided training program had a positive impact on the horses' acid-base status, although some adaptations are still required to improve their fitness.

Abstract
RESUMO Foram avaliados parâmetros fisiológicos e bioquímicos em equinos Quarto de Milha durante treinamento de três tambores, antes do condicionamento (T0), após o condicionamento (T1), após um percurso (T2), após descanso do percurso, por 20 minutos (T3) e após descanso do percurso, por 40 minutos (T4). Os parâmetros físicos avaliados foram: frequência cardíaca (FC), frequência respiratória (FR), temperatura retal (TR) e tempo de enchimento capilar (TEC); e os bioquímicos: sódio, potássio, cloreto, cálcio total, ureia, creatinina, osmolaridade, creatinaquinase, aspartato transaminase, proteínas totais (PT), glicose e lactato. A FC, a FR e a TR aumentaram após o percurso (T2), mas foram recompostas após 40 minutos de descanso. A concentração do lactato pouco aumentou após o condicionamento, mas altas concentrações ocorreram após o percurso (T2), e embora ele tenha diminuído após 20 (T3) e 40 minutos (T4) do percurso, ainda permaneceu acima dos limites normais. Nos demais parâmetros, não houve variações significativas. Concluiu-se que, ao final de um percurso de três tambores, o exercício sob máxima intensidade não ocasionou variações bioquímicas significativas nos equinos, exceto para o lactato, pois gerou uma hiperlactatemia que não foi restaurada até 40 minutos de descanso pós-percurso, mesmo com os parâmetros físicos já recompostos do esforço.
