Inertial training, also called flywheel training is more and more popular among sportsmen. The available data concerning the effectiveness of inertial training compared to conventional resistance strength training are contradictory. The aim of this study was to compare the impact of inertial training (IT) vs. traditional gravity-dependent resistance training (TRT) on elbow flexor and knee extensor strength.
Twenty-six young, recreationally active males were randomized into IT group (n = 13) or TRT group (n = 13). Both groups performed strength training three times a week for 6 weeks. Before and after training, the maximum force of the trained muscles was evaluated under training conditions (one repetition maximum under gravity-dependent conditions and maximal force under inertial conditions) and isometric conditions. Countermovement jump, squat jump, pull-up test, and limb circumference were also evaluated.
Elbow flexor muscle strength and arm circumference increased significantly in both IT and TRT over the course of training. There were no significant differences in relative muscle strength increases between groups. Knee extensor muscle strength also improved significantly in IT, regardless of the tested conditions, while TRT showed significant changes in one repetition maximum and isometric force but no significant changes in force obtained under inertial conditions. Thigh circumference increased in IT (P ≤ 0.05) but was unchanged in TRT. Jumping abilities improved significantly in both groups, without any differences between groups.
We cannot confirm the superiority of inertial training over traditional resistance training definitively. Nevertheless, inertial training had a slight advantage over traditional resistance training when knee extensor muscle training was considered.
惯性训练，也称为飞轮训练，在运动员中越来越受欢迎。与传统抗阻力量训练相比，关于惯性训练效果的现有数据相互矛盾。本研究的目的是比较惯性训练（IT）与传统重力依赖性抗阻训练（TRT）对肘屈肌和膝伸肌力量的影响。
26名年轻、有休闲运动习惯的男性被随机分为IT组（n = 13）或TRT组（n = 13）。两组均每周进行3次力量训练，共6周。在训练前后，在训练条件下（重力依赖性条件下的一次重复最大值和惯性条件下的最大力量）和等长条件下评估训练肌肉的最大力量。还评估了反向纵跳、深蹲跳、引体向上测试和肢体周长。
在训练过程中，IT组和TRT组的肘屈肌力量和上臂围均显著增加。两组之间相对肌肉力量增加没有显著差异。无论测试条件如何，IT组的膝伸肌力量也显著改善，而TRT组在一次重复最大值和等长力量方面有显著变化，但在惯性条件下获得的力量没有显著变化。IT组的大腿围增加（P≤0.05），而TRT组没有变化。两组的跳跃能力均显著提高，组间无差异。
我们不能明确证实惯性训练优于传统抗阻训练。然而，在考虑膝伸肌训练时，惯性训练比传统抗阻训练略有优势。
