“…The present project showed that 3-barrel racing produced significant changes in the iron metabolism, similarly to other studies including other equine disciplines (Inoue et al 2005;Machado et al 2010;Abramovitc et al 2014;Assenza et al 2014;Burlikowska et al 2015;Assenza et al 2016b). Values recorded through the experimental period are within the normal range described by Orsini and Divers (2013).…”

“…In this research, a significant rise of 27.3% was observed for SI in T1. Similar results were described in the jumping horses (Burlikowska et al 2015;Assenza et al 2016b;Piccione et al 2017), Lusitano horses (Minini et al 2013) and Thoroughbreds (Inoue et al 2002;Assenza et al 2016a). Mills et al (1996) also found elevated SI in racing and endurance horses during the first 24 h after exercise.…”

Energy metabolism and physical performance are dependent on sufficient iron metabolism. Therefore, studies evaluating the iron profile are necessary to elucidate this trace mineral requirements and its role in the equine exercise physiology. The aim of this study was to evaluate the influence of barrel racing exercise on serum iron profile of Quarter horses. Twenty-two regularly trained Quarter horses (8 females and 14 males, 4.8 ± 2.4 years old, mean body weight 431.7 ± 33.9 kg) were enrolled in this study with the owner’s informed consent. All horses were evaluated at T0 (at rest), T1 (immediately after barrel racing trial), T2 (30 min after trial) and T3 (2 h after trial). At these time points, blood samples were taken to determine the packed cell volume (PCV), red blood cell count (RBC), haemoglobin concentration (Hb), total protein (TP), serum iron (SI), total iron-binding capacity (TIBC) and transferrin saturation (TSAT). Variables were analyzed for normality through Kolmogorov-Smirnov test and comparisons were made using Tukey test, considering P < 0.05. The imposed exercise challenge significantly altered PCV, RBC, haemoglobin concentration, TP, SI and TSAT, with higher values were recorded at T1. These findings can be linked to an increased demand as a result of physical activity. Significant changes occurred in the iron status in physically well-conditioned Quarter horses during the barrel racing exercise. Better understanding of iron metabolism in horses will help determine the actual necessity of supplementation.

“…However, TIBC and serum iron values were similar to previous results with a standard training program (Assenza et al, 2016). Some studies have reported increased serum iron concentrations in horses following exercise, probably resulting from the release of iron from reticuloendothelial cells (Assenza et al, 2016;Assenza et al, 2017). Iron metabolism can be influenced by the duration and intensity of exercise (Assenza et al, 2016).…”

Hypoxic exposure results in physiological adaptions and enhanced human athletic performance. However, few reports exist regarding responses of horses to similar conditions. The goals of this preliminary work were to evaluate whether horses could be acclimated to a hypoxic chamber (HC) and to monitor their performance. Trial 1: Two 4-yr-old Thoroughbreds were used to establish protocols for adaptation to the HC. Horses were stalled in the HC for 8 to 10 h/d while O2 concentrations were decreased over 2 wk until 13.5% O2 was achieved. On d 37, horses were removed from the HC and shipped to a track for 7 d before reentering the HC for the remainder of the 2-month study. Resting hemoglobin (Hb) was measured on d 0, 37, and 61 and ranged from 14.8 to 15.2 g/dL. Trial 2: Two 2-yr-old Thoroughbreds were maintained in the HC at 13.5% O2 for 8 to 8.5 h/d for 21 d, shipped to a track for 5 d, and then placed back in the HC 8.5 h daily for the remainder of the 31-d trial. Horses were conditioned on the treadmill or track 6 d/wk. Horses underwent a standardized exercise test (SET) prior to being initially placed in the HC. The SET was repeated on d 10 and 31. Peak heart rate (HR) reached during exercise, and HR at 3 and 5 min post-exercise were recorded. Hemoglobin was measured immediately upon cessation of exercise. There was no difference in HR at 3 min (P=0.18), and 5 min post-exercise (P=0.64). Hb was greater on d 31 compared to d 0 (P

“…Exercise will cause increased destruction of serum ferritin cells, resulting in a decrease in the number of athletes' serum ferritin in the concentration of red blood cells, and a decrease in the total number of serum and ferritin concentrations. When the number concentration of hemoglobin, the number concentration of serum and hemoglobin in white blood cells decreases and reaches a certain level, it is the occurrence of sports iron deficiency anemia [12]. A large number of clinical research analysis results have confirmed that the training of some athletes may directly lead to the natural phenomenon that the symptoms of early sports anemia in humans rise sharply, and the training of some athletes may also directly cause the iron metabolic function of the human body.…”

Iron is an indispensable important element in the human body. Serum ferritin is a reservoir of iron. Serum protein concentration is an important indicator of the health of the shadow body. Both high and low concentrations are not conducive to physical health. The purpose of this article is to study the specific situation of the dynamic change of serum ferritin concentration during exercise and recovery. This article takes the white rat as the experimental object and uses radioimmunoassay to dynamically determine and analyze the serum ferritin concentration during exercise and recovery of the white rat result. The results of the study show that, compared with the quiet time, exercise can reduce the serum ferritin concentration in the mice from the original 36.7ng/ml to 27.1ng/ml, the concentration is reduced by 32.8%, and the serum ferritin concentration will gradually increase during recovery. After 4.2h, it returned to the quiet level, indicating that exercise can sharply reduce the serum iron albumin concentration in a short period of time, causing exercise anemia. Therefore, exercise and recovery after exercise can cause changes in the serum protein concentration in the body, change the metabolism rate of serum ferritin in the human body, and have a certain regulating effect on the serum ferritin concentration.
