Several factors, including age, sex, race number, post position, and race class, were evaluated for relationships to prerace percentage body weight loss and performance in all Greyhounds racing during August 1983 in Oregon. The incidence of percentage body weight loss greater than or equal to 2.5% was low (5%). Race number had a direct effect on weight loss; the later the dogs raced, the more weight loss they experienced. Female dogs were 3 times more likely to lose greater than 2.4% of body weight than males. All dogs experiencing greater than 2.4% body weight loss were 2 times more likely to finish in the first 3 places when racing in the first 5 races overall. In addition, males losing greater than 2.4% of body weight performed better than females when racing together in the final 6 races. Males appeared to be better performers than females, as they were twice as likely to be in class A races. However, once in the race, males and females performed equally.
对1983年8月在俄勒冈州参赛的所有灵缇犬的几个因素进行了评估，这些因素包括年龄、性别、参赛次数、起跑位置和比赛级别，以研究它们与赛前体重减轻百分比和比赛成绩之间的关系。体重减轻百分比大于或等于2.5%的发生率较低（5%）。参赛次数对体重减轻有直接影响；狗狗参赛越晚，体重减轻得越多。母犬体重减轻超过2.4%的可能性是公犬的3倍。在总共前五场比赛中，所有体重减轻超过2.4%的狗狗在前三名完赛的可能性是其他狗狗的2倍。此外，在最后六场比赛中一起参赛时，体重减轻超过2.4%的公犬比母犬表现更好。公犬似乎比母犬表现更好，因为它们参加A类比赛的可能性是母犬的两倍。然而，一旦进入比赛，公犬和母犬的表现相当。
