This study examined patterns of grip strength when maximal and submaximal effort are applied. Using a sensor glove, 50 healthy subjects performed two different power grips. Both maximal and submaximal gripping showed characteristic patterns of strength distribution that were independent of the degree of power applied. Significant differences were also noted in the strength distribution patterns, depending on whether the grip was performed at maximal, or submaximal, strength. The small finger plays a decisive role in this. In maximal strength gripping, the total measured strength is distributed relatively evenly over all four fingers, with each finger contributing between 23% and 27% of the total strength. In submaximal strength gripping, the little finger is involved very little and only contributes between 14% and 15% of the total strength, with the remainder of the gripping distributed relatively evenly between the index, middle and ring fingers, each of which contributes between 26% and 32% of the total.
本研究考察了在施加最大努力和次最大努力时的握力模式。50名健康受试者使用传感器手套进行了两种不同的强力握法。最大握力和次最大握力均呈现出与施加力量程度无关的特征性力量分布模式。根据握力是在最大强度还是次最大强度下进行，力量分布模式也存在显著差异。小指在其中起决定性作用。在最大强度握力时，测得的总力量相对均匀地分布在所有四根手指上，每根手指贡献总力量的23%至27%。在次最大强度握力时，小指参与度很低，仅贡献总力量的14%至15%，其余握力相对均匀地分布在食指、中指和无名指之间，每根手指贡献总力量的26%至32%。
