Handgrip strength test
fatigue
Handgrip strength was measured in kg using a Takei digital grip strength meter (T. K. K. 5401, Takei Scientific Instruments Co., Ltd.). Before the formal test, the subjects were required to squeeze the gripper with minimal force to confirm their understanding of the operating procedure and the gripping distance. The researchers randomly designated the dominant or non‐dominant hand to start the test. During the test, the subjects were asked to squeeze the gripper with one hand with maximum effort, maintain squeezing for at least 5 s, and repeat the test by changing hands at 60 s intervals to prevent fatigue. The subjects repeated the exchange method three times, and the individual maximum grip strengths of the two hands were recorded (Yang et al.,
