Harty, PS, Zabriskie, HA, Stecker, RA, Currier, BS, Moon, JM, Richmond, SR, Jagim, AR, and Kerksick, CM. Position-specific body composition values in female collegiate rugby union athletes. J Strength Cond Res 35(11): 3158-3163, 2021-Rugby union is a full-contact, intermittent team sport. Anthropometric characteristics of rugby union athletes have been shown to influence suitability for a given position and affect performance. However, little anthropometric data exist in female rugby union athletes. Thus, the purpose of this study was to report position-specific anthropometric, body composition, and bone density values in female collegiate rugby union athletes and to identify between-position differences in these variables. This investigation was a cross-sectional study involving 101 female collegiate rugby union athletes, categorized as forwards and backs as well as by position (props, hookers, locks, flankers, number 8 forwards, halfback, fly-half, centers, wings, and fullbacks). Anthropometric characteristics of all athletes were measured, and body composition was assessed via dual-energy x-ray absorptiometry. Outcome variables included age, height, body mass, BMI, body fat percentage, fat mass (FM), FM index, fat-free mass (FFM), FFM index, lean soft tissue, bone mineral content, bone mineral area, and bone mineral density. Anthropometric and body composition differences between forwards and backs were identified via independent t-tests and Mann-Whitney U tests, depending on normality of the variable. Between-position differences were assessed using one-way analysis of variances (ANOVAs) with Tukey post-hoc comparisons or Welch's ANOVA with Dunnett's T3 post-hoc test. Significant differences (p < 0.014) were identified between forwards and backs for every anthropometric variable, with forwards displaying greater height (167.7 ± 7.2 cm), body mass (81.5 ± 15.1 kg), and body fat percentage (28.2 ± 6.1%) relative to backs (164.5 ± 5.1 cm; 64.5 ± 7.7 kg; 21.9 ± 3.7%). Likewise, significant differences were identified for every anthropometric variable between several positions (p < 0.01). Significant (p < 0.05) interposition differences were identified within the subgroup of forwards, but not within the subgroup of backs. The present investigation is the first to report position-specific anthropometric and body composition data in female collegiate rugby union athletes. The results of this study can be used by rugby union coaches for recruiting and personnel decisions, to determine a player's suitability for a given position, and to further inform training and nutritional interventions in this population.
哈蒂，PS，扎布里斯基，哈，斯泰克，RA，柯里尔，BS，芒恩，JM，里士满，SR，贾吉姆，AR 和克斯里克，CM。女子大学橄榄球联盟运动员的特定身体部位组成值。J 力量与调理研究 35（11）：3158-3163，2021-橄榄球联盟是一项全接触、间歇性的团队运动。橄榄球运动员的人体测量特征已被证明会影响其适合特定位置，并影响表现。然而，在女子橄榄球联盟运动员中，几乎没有人体测量数据。因此，本研究的目的是报告女子大学橄榄球联盟运动员的特定身体部位的人体测量、身体成分和骨密度值，并确定这些变量在不同位置之间的差异。本研究是一项横断面研究，涉及 101 名女子大学橄榄球联盟运动员，分为前锋和后卫，以及根据位置（道具、钩子、锁、侧翼、8 号前锋、半卫、飞卫、中锋、翼锋和后卫）进行分类。对所有运动员进行了人体测量特征测量，并通过双能 X 射线吸收法评估身体成分。结果变量包括年龄、身高、体重、BMI、体脂百分比、脂肪量（FM）、FM 指数、去脂体重（FFM）、FFM 指数、瘦软组织、骨矿物质含量、骨矿物质面积和骨矿物质密度。通过独立 t 检验和曼-惠特尼 U 检验确定了前锋和后卫之间的人体测量和身体成分差异，具体取决于变量的正态性。通过单因素方差分析（ANOVA）和 Tukey 事后比较或 Welch 的 ANOVA 和 Dunnett 的 T3 事后检验评估了位置之间的差异。对于每个人体测量变量，前锋和后卫之间都存在显著差异（p < 0.014），与后卫相比，前锋的身高（167.7 ± 7.2 厘米）、体重（81.5 ± 15.1 千克）和体脂百分比（28.2 ± 6.1%）更大（164.5 ± 5.1 厘米；64.5 ± 7.7 千克；21.9 ± 3.7%）。同样，在几个位置之间也确定了每个人体测量变量的显著差异（p < 0.01）。在前锋的亚组中确定了显著的（p < 0.05）内部位置差异，但在后卫的亚组中没有。本研究首次报告了女子大学橄榄球联盟运动员的特定身体部位的人体测量和身体成分数据。这项研究的结果可以被橄榄球联盟教练用于招募和人员决策，以确定球员在特定位置的适合程度，并进一步为该人群的训练和营养干预提供信息。
