摘要

由于对动物健康和福利的关注,高速运动对年轻赛马肌肉骨骼系统的影响已经被广泛讨论。本研究调查了2012年至2015年巴西纯种马的年龄、桡骨远端骨化程度、性别和职业寿命之间的相关性。我们对286张年轻马左桡腕区的背侧胸片及其比赛表现进行了回顾性评估。桡骨远端骨骺闭合分为三个程度:A、B或c。成绩数据包括比赛次数、运动员职业生涯长度和每月比赛次数。对变量进行回归分析。x线检查时,公马明显大于母马,骨骺闭合程度随年龄不同而不同。首次参赛年龄为33.08±3.81个月,平均参赛次数为18.32±15.14次,运动生涯持续时间为20.37±13.82个月,每月参赛次数为0.93±0.46次。年龄影响赛马桡骨骺远端闭合(P < 0.001),但性别不影响(雄性P=0.218,雌性P=0.275)。在第一次比赛的年龄,每月比赛的次数和运动生涯持续时间之间观察到负相关。比赛频次和首次比赛年龄对运动员职业生涯持续时间有影响。

Influence of age and sex on bone development and athletic career longevity of Thoroughbred racehorses in Brazil - preliminary study
Abstract The impact of high-speed exercise on the musculoskeletal system of young racehorses has been extensively discussed because of concerns regarding animal health and welfare. This study investigated the correlation between age, degree of ossification of the distal radial epiphysis, sex, and career longevity of Thoroughbred racehorses in Brazil from 2012 to 2015. We performed a retrospective evaluation of 286 dorsopalmar radiographs of the left radiocarpal region of young horses and their racing performance. Distal radial epiphyseal closure was classified into three degrees: A, B, or C. Performance data included the number of races raced, athletic career length, and the number of races per month. The variables were subjected to regression analysis. At the time of radiographic examination, male horses were significantly older than females, and horses with epiphyseal closure degrees differed with age. Age at first race was 33.08±3.81 months, the average of races raced was 18.32±15.14 races, athletic career duration was 20.37±13.82 months, and the number of races raced per month was 0.93±0.46 races. Age influenced (P>0.001) the distal radial epiphyseal closure on racehorses, but sex did not (P=0.218 for males and P=0.275 for females). An inverse association was observed between age at the first race, the number of races raced per month, and athletic career duration. The frequency of race and the age at the first race influenced athletic career duration.
