The purpose of this monitoring study was to investigate how alterations in training affect changes in force-related characteristics and weightlifting performance.
Seven competitive weightlifters participated in the study.
The weightlifters performed a block style periodized plan across 20 weeks. Force plate data from the isometric mid-thigh pull and static jumps with 0 kg, 11 kg, and 20 kg were collected near the end of each training block (weeks 1, 6, 10, 13, 17, and 20). Weightlifting performance was measured at weeks 0, 7, 11, and 20.
Very strong correlations were noted between weightlifting performances and isometric rate of force development (RFD), isometric peak force (PF), peak power (PP), and jump height (JH). Men responded in a more predictable manner than the women. During periods of higher training volume, RFD was depressed to a greater extent than PF. JH at 20 kg responded in a manner reflecting the expected fatigue response more so than JH at 0 kg and 11 kg.
PF appears to have been more resistant to volume alterations than RFD and JH at 20 kg. RFD and JH at 20 kg appear to be superior monitoring metrics due to their "sensitivity."
本监测研究的目的是调查训练变化如何影响与力量相关的特征和举重表现的变化。
七名竞技举重运动员参与了该研究。
举重运动员在20周内执行了一个块状周期化计划。在每个训练阶段结束时（第1、6、10、13、17和20周）收集等长中大腿拉和0千克、11千克及20千克静态跳跃的测力台数据。在第0、7、11和20周测量举重表现。
观察到举重表现与等长力量发展速率（RFD）、等长峰值力量（PF）、峰值功率（PP）和跳跃高度（JH）之间存在非常强的相关性。男性的反应比女性更具可预测性。在训练量较高的时期，RFD比PF下降幅度更大。20千克时的JH比0千克和11千克时的JH更能反映预期的疲劳反应。
与20千克时的RFD和JH相比，PF似乎对训练量变化更具抗性。20千克时的RFD和JH因其“敏感性”似乎是更好的监测指标。
