Mechanical loading is a research area that focuses on studying the effects of physical forces and mechanical stresses on biological tissues, cells, and structures. This can include studying how mechanical loading affects bone density, muscle growth, tendon strength, and cartilage health. Researchers in this field may investigate the optimal levels of mechanical loading for promoting tissue growth and repair, as well as how excessive or insufficient mechanical loading can lead to injury or degeneration. Studies in mechanical loading often involve biomechanical testing, computational modeling, and analysis of cellular responses to mechanical stimuli. This research area has applications in fields such as orthopedics, sports science, and tissue engineering.
