Król, H and Gołaś, A. Effect of barbell weight on the structure of the flat bench press. J Strength Cond Res 31(5): 1321-1337, 2017-In this study, we have used the multimodular measuring system SMART. The system consisted of 6 infrared cameras and a wireless module to measure muscle bioelectric activity. In addition, the path of the barbell was measured with a special device called the pantograph. Our study concerns the change in the structure of the flat bench press when the weight of the barbell is increased. The research on the bench press technique included both the causes of the motion: the internal structure of the movement and the external kinematic structure showing the effects of the motion, i.e., all the characteristics of the movement. Twenty healthy, male recreational weight trainers with at least 1 year of lifting experience (the mean ± SD = 3.3 ± 1.6 years) were recruited for this study. The subjects had a mean body mass of 80.2 ± 8.6 kg, an average height of 1.77 ± 0.08 m, and their average age was 24.7 ± 0.9 years. In the measuring session, the participants performed consecutive sets of a single repetition of bench pressing with an increasing load (about 70, 80, 90, and 100% of their 1 repetition maximum [1RM]). The results showed a significant change in the phase structure of the bench press, as the barbell weight was increased. While doing the bench press at a 100% 1RM load, the pectoralis major changes from being the prime mover to being the supportive prime mover. At the same time, the role of the prime mover is taken on by the deltoideus anterior. The triceps brachii, in particular, clearly shows a greater involvement.
克罗尔，H和戈拉斯，A。杠铃重量对平板卧推结构的影响。《力量与体能研究杂志》31(5): 1321 - 1337，2017年 - 在本研究中，我们使用了多模块测量系统SMART。该系统由6台红外摄像机和一个无线模块组成，用于测量肌肉生物电活动。此外，杠铃的路径用一种叫做缩放仪的特殊装置进行测量。我们的研究关注当杠铃重量增加时平板卧推结构的变化。对卧推技术的研究包括运动的原因：运动的内部结构和显示运动效果的外部运动学结构，即运动的所有特征。本研究招募了20名健康的男性业余举重训练者，他们至少有1年的举重经验（平均±标准差 = 3.3 ± 1.6年）。受试者的平均体重为80.2 ± 8.6千克，平均身高为1.77 ± 0.08米，平均年龄为24.7 ± 0.9岁。在测量过程中，参与者以逐渐增加的负荷（约为他们一次重复最大值[1RM]的70%、80%、90%和100%）连续进行单组平板卧推。结果表明，随着杠铃重量的增加，卧推的阶段结构发生了显著变化。在以100% 1RM负荷进行卧推时，胸大肌从主要推动者变为辅助主要推动者。同时，主要推动者的角色由三角肌前束承担。特别是肱三头肌明显表现出更大的参与度。
