Sarcopenia was diagnosed based on the revised sarcopenia criteria for liver disease (second edition) proposed by the Japanese Society of Hepatology,16 including grip strength and skeletal muscle mass. Patients who met both criteria were diagnosed with sarcopenia. Grip strength was measured by a registered dietitian using a digital Smedley dynamometer (T.K.K.5101 GRIP‐D; Takei Scientific Instruments, Niigata, Japan), and the cutoff value for low grip strength was 28 kg for men and 18 kg for women. Skeletal muscle area was measured by estimating the cross‐sectional area of the abdominal skeletal muscles at the third lumbar vertebra using a computed tomography image analysis system (Synapse Vincent; Fujifilm, Tokyo, Japan). Skeletal muscle index (SMI) was calculated by dividing the skeletal muscle area by the square of the height, and the cutoff value for low SMI was 42 cm2/m2 for men and 38 cm2/m2 for women.

To assess bilateral isometric strength of quadriceps, we used MVC method on a leg extension machine (Nessfit NMI 1000, Bcube, Italy) equipped with a dynamometer (Tesys 800, Globus, Italy). The subjects sat positioned with knee and hip joint angle at 90°, and they were required to carry out maximal isometric contraction for 5 s using both legs contemporarily. The test was carried out three times with a recovery time of 2 min and the best performance was considered. We focused on quadriceps to adhere with the training protocols.
Maximal HS was measured with a specific dynamometer (T.K.K. 5101 GRIP-D, Takei Scientific Instruments, Japan). The subjects remained standing up and performed their maximal grip strength with the dominant upper limb, with the arm straight at their side. The test was carried out three times with recovery time of 2 min, and the best performance was considered. We focused on HS to provide a different functional model respect to the lower limb tests and to provide a widely used, simple and highly reliable test.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
