Abstract The aim of this paper is to determine inter-reliability, concurrent validity, and interchangeability of the SMS HG dynamometric system and a Jamar digital dynamometer for hand grip strength measurements performed in two relevant positions of the elbow joint, i.e. 90 ° flexion and 180 ° (full) extension. The sample in this research consisted of 61 participants and included 27 women and 34 men. Statistically significant differences in the results found between two positions in the elbow joint indicate that the results must be evaluated separately. However, regarding both testing positions, i.e. 90 ° flexion and 180 ° extension in the elbow joint, it was determined that SMS HG and Jamar instruments have a very high level of inter-reliability (ICC 0.948 to 0.980), but lack concurrent validity. The established mean difference of the results was higher for the 90 ° than for the 180 ° position but in both cases was considered to have a practical significance, thus not supporting the interchangeability of the instruments.

Sports Medical Solutions 手柄和 Jamar 手柄测功机的可靠性

摘要 本文的目的是确定 SMS HG 测力系统和 Jamar 数字测力计在肘关节的两个相关位置（即 90°屈曲和 180 °（全）扩展。本研究的样本包括 61 名参与者，其中包括 27 名女性和 34 名男性。在肘关节的两个位置之间发现的结果在统计学上有显着差异，这表明必须分别评估这些结果。然而，关于两个测试位置，即肘关节的 90°屈曲和 180°伸展，确定 SMS HG 和 Jamar 仪器具有非常高的相互可靠性水平（ICC 0.948 至 0.980），但缺乏同时效度。
