Jumping involves dynamic movements that place significant stress on the foot and lower limb, often leading to fatigue and injury among athletes. The foot arch plays a pivotal role in these movements by influencing energy storage and release during the push-off phase. Arch supports are commonly used in foot orthoses (FO) to provide stability and comfort; however, their impact on energy dynamics during high-performance sports has not been extensively studied. Specifically, there is limited research on how different arch support materials and structures affect energy cost, storage, and return during athletic tasks such as jumping and landing. Therefore, the aim of this study is to evaluate the effects of various FO with differing arch support designs on landing performance.
