Abstract

This study aimed to verify the effect of “marcha” training on clinical, hematological and biochemical variables in Mangalarga Marchador horses. Twelve Margalarga Marchador horses were used, six females and six males. Each animal was submitted to gait training lasting 40 minutes on hard ground. These animals were already conditioned to the proposed training. The animals were assessed before exercise (M0) and immediately after its ending (M1). Was realized physical examination and collected blood samples by jugular venipuncture to obtain blood, plasma and serum for hematological and biochemistry profiles. The “marcha” training caused changes in values of all clinical and laboratory variables evaluated. At the physical examination showed increases in cardiac and respiratory rates, as well as in rectal temperature. An increase was observed in erythrocyte, hemoglobin, hematocrit and leukocyte values. Electrolytes such as sodium, potassium, chloride, magnesium and ionic calcium showed a decrease in their plasma concentration. An increase in strong ion difference (SID) was observed due to the decrease of the chloride concentration causing a discreet metabolic alkalosis. There was an increase in the plasma concentrations of Lactate, glucose, CPK, total proteins and fibrinogen. As conclusion, the “marcha” causes small changes in the clinical, hematological and biochemical profiles in horses previously conditioned to this exercise.

Highlights

Physical training is a stressful condition that can cause important alterations to athlete homeostasis and can lead to injuries in different tissues, especially the musculoskeletal system
The evaluation of physiological and biochemical parameters based on a controlled training schedule, even during physical activity, allows for more accurate evaluation of the changes promoted in the body with regard to the conditioning of the animals and the athletic capacity of each breed, in varied sporting activities (Silva et al, 2015)
Paludo et al (2002) suggested that an increase in respiratory rate is one of the first lines of physiological defense when the body is subjected to thermal stress or physical activity

Summary

Introduction

Physical training is a stressful condition that can cause important alterations to athlete homeostasis and can lead to injuries in different tissues, especially the musculoskeletal system This leads to a decrease in athletic performance, duration of activity, and, financial losses for investors (Ferraz et al, 2007). The evaluation of physiological and biochemical parameters based on a controlled training schedule, even during physical activity, allows for more accurate evaluation of the changes promoted in the body with regard to the conditioning of the animals and the athletic capacity of each breed, in varied sporting activities (Silva et al, 2015). This evaluation has facilitated the preparation of training programs to be more technical, which will lead to improvements in the performance of competition horses
