The aim of the study was to investigate the relationships between handgrip and pinch strength values with basic body (body height, body mass, BMI) and with specific hand anthropometric parameters (fingers spans, lengths and perimeters) in prepubertal children. Body height, body mass and five fingers spans, lengths and perimeters were measured in 461 6-10 year old Estonian children according to Visnapuu & Jürimäe (2007). BMI was calculated (kg/m2). The maximal handgrip strength of the right and left hand was measured with hand dynamometer. The right and left key and tip pinch were measured with a pinch gauge. Body height, as a rule, in combination with BMI, was the strongest predictor of handgrip strength, especially in older children (about 40-60 % of the total variance, R2 x 100). From the hand anthropometry, the most important span parameter was FS2 (see explanations in the methods), which explained about 10-50% (R2 x 100) of the total variance. In older groups, the FS1 and FS3 were added to the models. From the length parameters, the most important was IFL, which in younger groups together with MFL explained 10-30% of the total variance, and in older groups the addition of RFL increased the influence to 45% (R2 x 100). From the perimeters, the most important one was P2 which explained the variability of the handgrip strength in younger groups by 15-30% (R2 x 100) and in older groups together with P3 and P4 even 30-40%. In children, the basic anthropometric parameters (body height and BMI) contribute more to the prediction of handgrip strength than the specific anthropometric parameters. With increasing age the contribution of basic and specific hand anthropometry increases and the relation between anthropometry and handgrip strength is stronger in boys compared with girls. The relation of basic and hand anthropometry to the tip and key pinch strength is relatively low.
本研究的目的是调查青春期前儿童的握力和捏力值与基本身体指标（身高、体重、体重指数）以及特定手部人体测量参数（手指跨度、长度和周长）之间的关系。根据维斯纳普和尤里马埃（2007年）的方法，对461名6至10岁的爱沙尼亚儿童测量了身高、体重以及五指的跨度、长度和周长。计算了体重指数（kg/m²）。用握力计测量右手和左手的最大握力。用捏力计测量右手和左手的钥匙捏力和指尖捏力。通常，身高与体重指数相结合，是握力的最强预测指标，尤其是在年龄较大的儿童中（约占总方差的40 - 60%，R²×100）。从手部人体测量学来看，最重要的跨度参数是FS2（见方法部分的解释），它解释了总方差的约10 - 50%（R²×100）。在年龄较大的组中，FS1和FS3被纳入模型。从长度参数来看，最重要的是IFL，在较年轻的组中，它与MFL一起解释了总方差的10 - 30%，在年龄较大的组中，加入RFL后影响力增加到45%（R²×100）。从周长来看，最重要的是P2，它在较年轻的组中解释了握力变异性的15 - 30%（R²×100），在年龄较大的组中，与P3和P4一起甚至解释了30 - 40%。在儿童中，基本人体测量参数（身高和体重指数）对握力预测的贡献比特定人体测量参数更大。随着年龄的增长，基本和特定手部人体测量学的贡献增加，与女孩相比，男孩中人体测量学与握力之间的关系更强。基本和手部人体测量学与指尖捏力和钥匙捏力的关系相对较低。
