Effect of Lactate Minimum Speed-Guided Training on the Fluid, Electrolyte and Acid-Base Status of Horses.

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, pCO, HCO, and electrolyte measurements. The LMS and strong ion difference (SID) were calculated. A mild increase in the mean values ( > 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), pCO (from 42.95 ± 1.58 to 45.06 ± 0.81 mmHg), HCO (from 27.01 ± 1.02 to 28.91 ± 0.86 mmol/L), and SID (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.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research evaluates how a treadmill training program guided by lactate minimum speed (LMS) impacts the fluid, electrolyte and acid-base balance of untrained Arabian horses. It showed overall benefits to the horses’ acid-base status with certain adjustments needed for better fitness.

Objective and Methodology of the Research

  • The study aims to understand how the LMS-guided training program affects the fluid, electrolyte, and acid-base status of horses. This was conducted considering the lack of research on how homeostasis is affected by LMS in horses.
  • Ten Arabian horses which had no prior training were subjected to an LMS test on a treadmill. This occurred both before and after they underwent a training program for six weeks.
  • The training program was structured such that in the initial three sessions, the intensity of the training was 80% of the LMS, and for the remainder, it was 100% of the LMS.
  • At two points i.e. before (T-1) and after (T-2) the training program, the venous blood of the horses was collected. This was to measure parameters such as lactate, pH, pCO, HCO, and electrolyte levels during and after the LMS test.
  • Compounds to calculate the LMS and the strong ion difference (SID) were also evaluated.

Results of the Study

  • In T-2, when compared with T-1, a slight increase was observed in the average values of pH (from 7.436 ± 0.013 to 7.460 ± 0.012), pCO (from 42.95 ± 1.58 to 45.06 ± 0.81 mmHg), HCO (from 27.01 ± 1.02 to 28.91 ± 0.86 mmol/L), and SID (from 33.42 ± 1.45 to 35.06 ± 2.94 mmol/L).
  • During T-2, these variables showed more stability than during T-1.
  • Although there was an overall improvement in fitness, there was no significant difference in the LMS (from 5.40 ± 0.55 to 5.52 ± 0.20 m/s).

Conclusion

  • The study concluded that the LMS-guided program had positive effects on the acid-base status of the horses. This could have long-term benefits in terms of the horses’ ability to maintain homeostasis during and after exertion.
  • However, it was also noted that some adaptations are still needed. Despite an overall improvement in fitness, no significant change in LMS suggests that additional adjustments to the training program could help improve the horses’ fitness further.
