“…There have been studies in which the lactic acid concentration increases high when the heart rate reaches 200 (beats/min) or higher, which is close to the maximum heart rate, and there have been studies in which the lactic acid concentration decreases and recovers after 15 min of exercise (Schuback and Essén-Gustavsson 1998). Lactic acid is produced by anaerobic metabolism, the intensity of exercise is known to be closely related to muscle fatigue, correlates with heart rate, and other studies have shown that heart rate and lactic acid levels can be used as indicators of momentum (Schuback and Essén-Gustavsson 1998;Popov and Vinogradova 2012;Angélica et al 2021).…”

This study was conducted to secure basic data for improving the welfare of domestic breeding horses by measuring the accumulation of heart rate and lactic acid before and after exercise and measuring the concentration of Cortisol and HSP70 as indicators for horse stress. For three sessions before exercise, immediately after exercise, and 30 min after exercise, 15 Thoroughbred racing horses and 15 riding horses in domestic breeding were designated, and lactate was measured in plasma using a poly equine health check Polar H10 heart rate meter. In addition, the concentrations of HSP70 and Cortisol, which can be taken as values of stress in three sessions, were analyzed. The levels of HSP70 were measured as 29.43±5.72pg/mL before exercise, 89.74±23.02pg/mL after exercise, 32.19±6.57pg/mL after 30 min of exercise, 41.25±8.26pg/mL before exercise, and 114.02±29pg/mL after exercise (pg/mL) after exercise. Cortisol concentrations were found to be 3.38±1.2µg/dL before exercise, 5.11±1.16µg/dL immediately after exercise, 5.58±2.15µg/dL after 30 min of exercise, 6.61±2.04µg/dL before exercise, 8.47±2.55µg/dL immediately after exercise, and 30 min after exercise. Hematology chemistry in riding horse and racing horses had some differences by items, but there was no significant difference overall. In conclusion, it has been confirmed that racing horses have higher stress from strong exercise compared to riding horses, and plans to use it to promote the welfare of domestic horses in the future.

“…Lactate concentrations, as a measure of anaerobic threshold, are commonly used to assess the level of fitness in equine athletes [ 33 , 34 ]. In a study performed by Cabrera et al [ 35 ], lactate concentrations reached the anaerobic threshold directly after high-intensity and maximum-intensity exercise and returned to aerobic levels during the recovery period, which was 10 min post-exercise. Therefore, the increase above 4 mmol/L in lactate concentrations at 1 min post-exercise across all treatments observed in the current study indicates that each horse was exercising anaerobically.…”

Rice bran oil and flaxseed oil contain omega-3 fatty acids with the potential to reduce post-exercise inflammation and muscle damage. This study measures plasma interleukin-1β and creatine kinase and fatty acid profiles in lightly worked, young horses (Equus caballus) undergoing an exercise test after 60 days (d) of oil consumption, where the oil replaced 25% of concentrate calories. Treatments consisted of CON (no oil), FLAX (flaxseed oil blend), and RICE (crude rice bran oil). Blood was collected pre-exercise, and again at 1 min, 30 min, 24 h, 48 h, and 72 h post-IET. Data were analyzed by repeated measures ANOVA. Plasma creatine kinase activity was not different in CON during the study, greater (p < 0.05) in RICE from pre-exercise to 30 min post-exercise across all exercise tests, and lesser (p < 0.05) in FLAX at 30 min post-exercise on d 30 compared to d 0. Plasma interleukin-1β was greater (p < 0.01) in CON on d 60, but no differences were observed in FLAX and RICE throughout the study. Plasma alpha-linolenic and linoleic acids were greatest (p < 0.05) in FLAX after 30 d of inclusion, while CON horses had greater (p < 0.05) EPA across all exercise tests and DHA after 60 d. These results indicate that 60 d of inclusion of crude rice bran oil or a flaxseed oil blend may benefit lightly worked, young horses by reducing training-program-related increases in interleukin-1β, while a flaxseed oil blend may reduce exercise-induced increases in creatine kinase. Additionally, the flaxseed oil blend has the potential to increase plasma omega-3 and omega-6 fatty acids. Replacing 25% of concentrate calories with flaxseed or rice bran oil has potential benefits for young horses in training.

“…The horses compensatory physiological response during exercise changes in hematological and blood biochemical parameters. This compensatory physiological response involves the integration of multiple organ systems which communicate via neural and endocrine pathways (Trailović 2008;Hinchcliff et al 2008;Mc Gowan and Hodgson 2014;Cabrera et al 2022).…”

Good horse performance depends on a genetic predisposition, training, health status, and optimal values of hematological and biochemical blood parameters. This research aimed to monitor 20 hematological and 15 biochemical blood parameters during different types of physical activity in clinically healthy 20 sports and 20 working horses with an average age of 8.33 years. Sport male horses had higher MCV, MCH, number, and percentage of neutrophils, eosinophils, creatinine, and bilirubin, while mares had higher values of RDW, lymphocytes, monocytes, basophils, MPV, glucose, BUN-to-creatinine ratio. Physical activity in draft horses led to a statistically significant increase in the number of leukocytes and neutrophils and significant hypocalcemia, while in sport horses, there was a significant increase in RBC, HCT, and HGB and significant hypoglycemia after rest. Significantly higher values of neutrophils and creatinine were recorded in male draft horses, while in mares, there were higher values of lymphocytes and amylase. This study proved that sport horses have better aerobic capacity and performance, are better adapted to the type and intensity of physical activity, and are kept in better conditions than draft horses. The different types of physical activity and other physiological factors can significantly change hematological and biochemical parameters in the draft and sports horses. Monitoring of hematological and biochemical blood parameters during different types of exercise is essential to assessing horses' performance, welfare status, and health status.
