Transmission Electron Microscopy Used to Observe the Transversal Tension Transfer of Skeletal Muscle Caused by Acute Centrifugation

The change of lateral tension of skeletal muscle can have a direct impact on the injury of skeletal muscle. Acute centrifugal exercise is a major factor to promote the transverse tension transfer of skeletal muscle. The purpose of this study is to determine a scientific and reasonable centrifugal movement mode by studying the changes of lateral tension transfer of skeletal muscle caused by acute centrifugal movement. In this paper, the relevant theories and concepts of transmission electron microscope, acute centrifugal exercise and skeletal muscle are explained at first, especially the acute responses of acute centrifugal exercise in three aspects of metabolic cardiopulmonary response, molecular level response and repetition effect are analyzed. The change of lateral tension transfer of skeletal muscle caused by acute centrifugal movement was analyzed concretely by rat model experiment. The results showed that: compared with the intensity of acute centrifugal exercise, the lateral tension of skeletal muscle increased significantly after acute exercise, from 0.36 to 0.65, with a change range of 0.29. The lateral tension before acute exercise increased from 0.24 to 0.29, with a change of only 0.05. Taken together, acute centrifugation can promote an increase in skeletal muscle transverse tension transfer.
