In modern educational environments, biomechanics, which examines the principles of human movement and mechanics, offers new perspectives and solutions, particularly in online and long-term learning contexts. Teachers need not only to focus on optimizing teaching content and strategies but also to consider students’ physical adaptations and cognitive load. The application of biomechanics can help improve students’ learning experiences through the systematic design of learning environments, the adjustment of teaching objectives and methods, and the reduction of the negative effects of improper body postures, exercise loads, and fatigue, thereby enhancing learning efficiency. This study examines the multiple applications of biomechanics in education, including its influence on teaching goals, the optimization of content selection, the improvement of teaching methods, and the protection of students’ physical health. Biomechanical principles help teachers identify and analyze students’ physiological responses during the learning process, such as muscle fatigue, as well as improper posture, and recommend appropriate adjustments. For example, appropriate study postures and regular breaks can significantly reduce students’ physical load and improve their concentration and learning efficiency. Through the application of biomechanical principles, teachers can design teaching activities that meet students’ physiological needs, prevent health problems caused by poor posture or fatigue, and ensure that students learn efficiently while maintaining their physical health.
