James, LP, Comfort, P, Suchomel, TJ, Kelly, VG, Beckman, EM, and Haff, GG. Influence of power clean ability and training age on adaptations to weightlifting-style training. J Strength Cond Res 33(11): 2936-2944, 2019-The purpose of this investigation was to determine whether weightlifting actions are a viable method for improving athletic performance among weaker, inexperienced lifters when compared with individuals with a greater power clean (PC) result, and hence weightlifting ability and experience. Two groups of males with distinctly different PC performances (higher performance [HP]: N = 8; body mass [BM] = 78.1 ± 4.0 kg; 1 repetition maximum [1RM] PC = 1.08 ± 0.09 kg·BM; lower performance [LP]: N = 8; BM = 82.6 ± 14.0 kg; 1RM PC = 0.78 ± 0.1 kg·BM) and resistance training age (HP: resistance training experience = 3.5 ± 1.2 years; LP: resistance training experience = 1.44 ± 1.50 years) undertook 10 weeks of training involving weightlifting derivatives, in addition to supplemental ballistic and plyometric exercises. Testing of athletic performance (represented by measures derived from the countermovement jump) occurred at baseline, after 5 weeks of training, and after 10 weeks of training. Both groups significantly improved across the majority of outcome variables after training (Hedges' g = 0.98-2.55, p ≤ 0.01-0.05). Only the HP participants experienced significant changes at midtest (g = 0.99-1.27, p ≤ 0.01-0.05), whereas no significant changes were revealed between midtest and posttest in this group. In contrast to this, the LP participants displayed a significant improvement in relative impulse (g = 1.39, p < 0.01) and rate of force development (g = 1.91, p < 0.01) during this final period (p < 0.01). As weaker, inexperienced lifters underwent a significant and meaningful enhancement in maximal neuromuscular measures after weightlifting derivative-focused training, practitioners should consider early implementation of such exercises. However, it is important for coaches to note that a delayed training effect might be present in weaker, less experienced lifters.
詹姆斯、LP、舒适、P、Suchomel、TJ、凯利、VG、贝克曼、EM 和 Haff、GG。力量清洁能力和训练年龄对举重式训练适应的影响。J 力量与条件研究 33(11):2936-2944,2019-本研究的目的是确定举重动作是否是一种可行的方法，可以提高较弱、无经验的举重者的运动表现，与具有更大力量清洁(PC)结果的个体相比，举重能力和经验。两组男性具有明显不同的 PC 表现(高表现[HP]:N=8;体重[BM]=78.1±4.0kg;1 重复最大值[1RM]PC=1.08±0.09kg·BM;低表现[LP]:N=8;BM=82.6±14.0kg;1RM PC=0.78±0.1kg·BM)和阻力训练年龄(HP:阻力训练经验=3.5±1.2 年;LP:阻力训练经验=1.44±1.50 年)进行了 10 周的训练，包括举重衍生训练，以及补充的弹道和 plyometric 练习。运动表现的测试(由反冲跳的测量结果表示)在基线、5 周训练后和 10 周训练后进行。两组在训练后大多数结果变量都有显著改善(赫奇斯 g=0.98-2.55，p≤0.01-0.05)。只有 HP 参与者在中期测试中经历了显著变化(g=0.99-1.27，p≤0.01-0.05)，而在这一组中，中期测试和后期测试之间没有显示出显著变化。与此相反，LP 参与者在最后阶段显示出相对脉冲的显著改善(g=1.39，p<0.01)和力发展率的显著改善(g=1.91，p<0.01)(p<0.01)。由于较弱、无经验的举重者在举重衍生训练后进行了显著和有意义的最大神经肌肉测量增强，从业者应考虑早期实施此类练习。然而，教练应该注意到，较弱、经验较少的举重者可能会出现延迟的训练效果。
