With the recent advances in scientific technologies, analytical techniques have markedly progressed, leading to the development of a musculoskeletal model-based analytical method to simultaneously examine multiple muscles using data on coordinates. This new method allows us to evaluate the activities of various muscles, including deep muscles that have been difficult to evaluate using conventional methods. On the basis of the results of analysis using this method, this study explains the characteristics of various types of muscle activities when delivering overhead strokes.
