The aim of this study was to examine the relationship between force and rate of force development with electroencephalogram correlates. The primary question was whether the different components of movement related potentials (MRPs) were related to specific properties of force output while subjects performed index finger force production tasks. The peak force and rate of force development (e.g., a product of peak force over time-to-peak force) were manipulated, and the effects of these manipulations on components of MRPs preceding and accompanying force production tasks were examined. The hypothesis was that the rate of force development, rather than level of force itself, would directly influence the later component of MRPs. Consistent with this hypothesis was the finding that the amplitudes of MRP components preceding (MP) and accompanying (MMP, MTP) finger force production movements were significantly correlated with force development rate.
本研究的目的是研究力量与力量发展速率之间的关系以及脑电图相关性。主要问题是，在受试者执行食指力量产生任务时，运动相关电位（MRP）的不同成分是否与力量输出的特定属性相关。对峰值力量和力量发展速率（例如，峰值力量与达到峰值力量的时间之比）进行了操控，并研究了这些操控对力量产生任务之前和伴随过程中MRP成分的影响。假设是力量发展速率而非力量本身的水平会直接影响MRP的后期成分。与该假设一致的是，发现手指力量产生动作之前（MP）和伴随过程中（MMP、MTP）的MRP成分的幅度与力量发展速率显著相关。
