Delgado, J, Drinkwater, EJ, Banyard, HG, Haff, GG, and Nosaka, K. Comparison between back squat, Romanian deadlift, and barbell hip thrust for leg and hip muscle activities during hip extension. J Strength Cond Res 33(10): 2595-2601, 2019-This study compared muscle activities of vastus lateralis (VL), biceps femoris (BF), and gluteus maximus (GM) during the back squat (SQ), Romanian deadlift (RDL), and barbell hip thrust (BHT) exercises performed with the same load (60 kg) and at one repetition maximum (1RM). Eight men with a minimum of 1 year's lower-body strength training experience performed the exercises in randomized order. Before each exercise, surface electromyography (EMG) was recorded during a maximal voluntary isometric contraction (MVIC) and then used to normalize to each muscle's EMG during each trial. Barbell hip thrust showed higher GM activity than the SQ (effect size [ES] = 1.39, p = 0.038) but was not significantly different from RDL (ES = 0.49, p = 0.285) at 1RM. Vastus lateralis activity at 1RM during the SQ was significantly greater than RDL (ES = 1.36, p = 0.002) and BHT (ES = 2.27, p = 0.009). Gluteus maximus activity was higher during MVIC when compared with the 60 kg load for the SQ (ES = 1.29, p = 0.002) and RDL (ES = 1.16, p = 0.006) but was similar for the BHT (ES = 0.22, p = 0.523). There were no significant differences in GM (ES = 0.35, p = 0.215) and BF activities (ES = 0.16, p = 0.791) between 1RM and MVIC for the SQ. These findings show that the RDL was equally as effective as the BHT for isolating the hip extensors, while the SQ simultaneously activated the hip and knee extensors.
德尔加多、J、德林沃特、EJ、巴纳德、HG、哈夫、GG 和野崎、K。在髋关节伸展时，比较后深蹲、罗马尼亚硬拉和杠铃臀桥对腿部和臀部肌肉活动的影响。J 力量与调节研究 33(10)：2595-2601，2019-本研究比较了在相同负荷（60 公斤）和 1 次最大重复次数（1RM）下进行后深蹲（SQ）、罗马尼亚硬拉（RDL）和杠铃臀桥（BHT）练习时，股外侧肌（VL）、股二头肌（BF）和臀大肌（GM）的肌肉活动。8 名有至少 1 年下肢力量训练经验的男性以随机顺序进行练习。在每项运动之前，进行最大自主等长收缩（MVIC）期间记录表面肌电图（EMG），然后将其用于对每次试验中每个肌肉的 EMG 进行归一化。在 1RM 时，杠铃臀桥显示出比 SQ 更高的 GM 活动（效应量 [ES] = 1.39，p = 0.038），但与 RDL 无显著差异（ES = 0.49，p = 0.285）。在 1RM 时，SQ 股外侧肌活动显著大于 RDL（ES = 1.36，p = 0.002）和 BHT（ES = 2.27，p = 0.009）。与 SQ 和 RDL 的 60 公斤负荷相比，GM 在 MVIC 时的活动更高（ES = 1.29，p = 0.002）和 RDL（ES = 1.16，p = 0.006），但对于 BHT 则相似（ES = 0.22，p = 0.523）。在 1RM 和 MVIC 时，SQ 的 GM（ES = 0.35，p = 0.215）和 BF 活动（ES = 0.16，p = 0.791）之间没有显著差异。这些发现表明，RDL 与 BHT 一样有效，可以隔离髋关节伸肌，而 SQ 则同时激活髋关节和膝关节伸肌。
