The maximum strength of the hand-squeeze muscles will give the grip strength when making the punch. With good hand-wringing muscle strength, it can increase the power of the punch which affects accuracy. The purpose of this study was to determine the effect of hand-squeezing muscles on blows in badminton. With a large hand-squeeze muscle strength, it can increase the strength of the hand swing which can affect the outcome of the hit. This study uses a quantitative research approach with descriptive analysis research type. This research approach is to collect data in the form of numbers. The method used is descriptive analysis. The research subjects were members of the student activity unit (ukm) badminton at the PGRI Adi Buana University Surabaya, which amounted to 20 members. The data collection method in this study was to measure the strength of the hand-squeeze muscles using a dynamometer handgrip measuring instrument. Based on the results of descriptive analysis using SPSS 20, it shows that the average hand-squeeze muscle strength of male members is 44.85, which is included in the "medium" category. Then for the hand-squeezing muscle strength of the average woman is 27.20 which is included in the "medium" category. From these results, it can be seen that the strength of the hand-squeezing muscles in the badminton student activity unit (ukm) of the Universitas PGRI Adi Buana Surabaya is in the "medium" category.
