The aim of this study was to evaluate the modifications of some haematological parameters and iron profile during an 80-day training program and their relationship with athletic performance of performance horses.
During the training period, 20 Thoroughbreds were subjected to a standardised exercise test, previously standardised for gallopers to evaluate athletic performance. The test was performed immediately before the beginning of the training program (T0) and after 30 days (T30), 60 days (T60) and 90 days (T90). For each horse, their velocities at blood lactate concentrations of 2 and 4 mmol/L (V2 and V4) and a heart rate of 200 beats/min (V200) were calculated to assess the effect of the training program on athletic performance. Blood samples were collected at 20-day intervals over a period of 80 days from the beginning of the training program.
One-way repeated measures analysis of variance (ANOVA) showed a statistically significant effect of days of training (time) on iron, ferritin, transferrin, total iron-binding capacity, transferrin saturation and unsaturated iron-binding capacity (P < 0.001 for all).
The results showed the influence of the intensity and duration of exercise on iron metabolism. These findings may be useful for evaluating the athletic status of horses during training and to assess the degree of training adaptability, providing an opportunity to modify the training schedule to achieve the desired performance.
本研究旨在评估80天训练计划期间一些血液学参数和铁代谢指标的变化及其与运动马运动成绩的关系。
在训练期间,20匹纯种马接受了标准化运动测试,该测试先前已针对疾驰马进行标准化以评估运动成绩。测试在训练计划开始前(T0)以及30天(T30)、60天(T60)和90天(T90)后进行。计算每匹马在血乳酸浓度为2和4 mmol/L时的速度(V2和V4)以及心率为200次/分钟时的速度(V200),以评估训练计划对运动成绩的影响。从训练计划开始起的80天内,每隔20天采集一次血样。
单向重复测量方差分析(ANOVA)显示,训练天数(时间)对铁、铁蛋白、转铁蛋白、总铁结合力、转铁蛋白饱和度和不饱和铁结合力有统计学显著影响(所有P值均<0.001)。
结果表明运动强度和持续时间对铁代谢有影响。这些发现可能有助于评估马匹训练期间的运动状态以及评估训练适应程度,为调整训练计划以达到理想成绩提供契机。
