Madruga-Parera, M, Bishop, C, Fort-Vanmeerhaeghe, A, Beato, M, Gonzalo-Skok, O, and Romero-Rodríguez, D. Effects of 8-weeks of Isoinertial vs. Cable-resistance Training on Motor Skills Performance and Interlimb Asymmetries. J Strength Cond Res 36(5): 1200-1208, 2022-The aim of this study was to compare the effects of 8 weeks of isoinertial vs. cable-resistance training on motor skills performance and interlimb asymmetries in handball players. Thirty-four young male handball players (mean ± SD: age: 15.96 ± 1.39 years; height: 1.74 ± 0.73 m; body mass: 70.5 ± 13.3 kg) participated in a randomized trial. The players performed an isoinertial program using a portable flywheel device or a cable-resistance device. Performance variations and interlimb asymmetries in dominant (D) and nondominant (ND) limb means of the unilateral countermovement jump (UCMJ), the unilateral lateral jump (ULJ), the unilateral broad jump (UBJ), handball throwing (HT), change of direction speed (COD180), the linear sprint (S20), the V-CUT test, and the repeated change of direction (RCOD) were recorded. Significant interactions were shown in RCODD (p = 0.003, ηp = 0.25), HT (p = 0.015, ηp = 0.17) and UCMJASY (p = 0.037, ηp = 0.13). Post-hoc testing revealed higher effect sizes in the isoinertial group (p < 0.05) for the performance improvements in RCODD (-1.35 large vs. -0.22, small) and HT (0.88, moderate vs. 0.00, trivial), in addition to interlimb asymmetry reductions in UCMJASY (-0.70 moderate vs. -0.32, small). Significant main effects of time in COD180, RCOD, UCMJ, and UBJ for both limbs (p < 0.05, from moderate to large effect size), and in ULJND (p < 0.001, large), UCMJASY (p < 0.001, moderate), V-CUT (p = 0.014, small), and HT (p = 0.015, large) were found. The effect sizes revealed greater magnitudes in the isoinertial group. In conclusion, although both resistance training programs improve players' to physical performance and reduce interlimb asymmetries, greater improvements were recorded with the isoinertial resistance training than with the cable-resistance methodology.
马德鲁加 - 帕雷拉，M，毕晓普，C，福特 - 范梅尔哈格，A，贝托，M，贡萨洛 - 斯科克，O，以及罗梅罗 - 罗德里格斯，D。8周等惯性训练与绳索抗阻训练对运动技能表现和肢体间不对称性的影响。《力量与体能研究杂志》36(5): 1200 - 1208，2022年 - 本研究的目的是比较8周等惯性训练与绳索抗阻训练对男子手球运动员运动技能表现和肢体间不对称性的影响。34名年轻男性手球运动员（均值±标准差：年龄：15.96±1.39岁；身高：1.74±0.73米；体重：70.5±13.3千克）参与了一项随机试验。运动员们使用便携式飞轮装置或绳索抗阻装置进行等惯性训练计划。记录了单腿反向纵跳（UCMJ）、单腿侧向跳（ULJ）、单腿跳远（UBJ）、手球投掷（HT）、变向速度（COD180）、直线冲刺（S20）、V字切入测试以及重复变向（RCOD）中优势（D）和非优势（ND）肢体的表现变化和肢体间不对称性。在RCODD（p = 0.003，ηp = 0.25）、HT（p = 0.015，ηp = 0.17）和UCMJASY（p = 0.037，ηp = 0.13）中显示出显著的交互作用。事后检验显示，等惯性训练组在RCODD（-1.35，大效应量 vs. -0.22，小效应量）和HT（0.88，中等效应量 vs. 0.00，微小效应量）的表现改善方面，以及在UCMJASY的肢体间不对称性降低方面（-0.70，中等效应量 vs. -0.32，小效应量），效应量更高（p < 0.05）。在COD180、RCOD、UCMJ和UBJ的双下肢方面（p < 0.05，效应量从中等到大），以及在ULJND（p < 0.001，大效应量）、UCMJASY（p < 0.001，中等效应量）、V字切入（p = 0.014，小效应量）和HT（p = 0.015，大效应量）方面发现了显著的时间主效应。效应量显示等惯性训练组的幅度更大。总之，虽然两种抗阻训练计划都能提高运动员的身体表现并减少肢体间不对称性，但等惯性抗阻训练比绳索抗阻方法记录到的改善更大。
