Spence, A-J, Helms, ER, and McGuigan, MR. Range of motion is not reduced in national-level New Zealand female powerlifters. J Strength Cond Res 35(10): 2737-2741, 2021-Some research suggests male powerlifters have less range of motion (ROM) in several directions about the shoulder and hip compared with sedentary men. In addition, those differences may be more pronounced in groups with higher strength levels and more years of experience. However, there is no information on ROM in female powerlifters. The purpose of this study was to evaluate single-joint ROM in competitive female powerlifters and determine whether single-joint ROM would be an effective predictor of strength in this population. Twelve female powerlifters and 12 female recreationally trained age-matched controls attended one testing session. Subjects reported their years of training experience, frequency, and average duration of training sessions. Active ROM measurements were collected at the shoulder, hip, and knee, using goniometry. There was no significant difference (p > 0.05) between groups for age, height, body mass, training experience, and training frequency. Powerlifters reported significantly greater (p ≤ 0.05) training durations than recreationally trained women. Powerlifters had significantly greater shoulder horizontal abduction on the right side (p = 0.022, g = 0.97), but no other ranges were significantly different between groups, and no ranges were significantly related to strength. Powerlifting does not seem to affect shoulder, hip, or knee ROM differently than recreational resistance training in women. Single-joint ROM was not an effective predictor of strength in female powerlifters.
斯宾塞、A-J、赫尔姆斯、ER 和麦圭根，MR。国家级新西兰女性力量举运动员的活动范围没有减少。J 力量与调节研究 35（10）：2737-2741，2021 年-一些研究表明，与久坐不动的男性相比，男性力量举运动员在肩部和臀部的几个方向上的活动范围（ROM）较小。此外，这些差异在力量水平较高和经验较多的群体中可能更为明显。然而，关于女性力量举运动员的 ROM 信息却没有。本研究的目的是评估竞技女性力量举运动员的单关节 ROM，并确定单关节 ROM 是否是该人群力量的有效预测指标。12 名女性力量举运动员和 12 名年龄匹配的女性休闲训练对照组参加了一次测试。受试者报告了他们的训练经验年限、训练频率和平均训练时间。使用测角器在肩部、臀部和膝盖处采集主动 ROM 测量值。两组在年龄、身高、体重、训练经验和训练频率方面无显著差异（p>0.05）。力量举运动员报告的训练时间明显更长（p≤0.05）比休闲训练女性。力量举运动员右侧肩部水平外展明显更大（p=0.022，g=0.97），但两组间无其他范围有显著差异，且无范围与力量有显著相关性。力量举似乎不会对女性的肩部、臀部或膝盖 ROM 产生与休闲抗阻训练不同的影响。单关节 ROM 不是女性力量举运动员力量的有效预测指标。
