Does the Structure of the Tendon Relate to the Temporal, Kinetic and Kinematic Jump Variables? Athletes Vs. Non Athletes

The goal of this observational study is to investigate the relationship between temporal, kinetic, and kinematic jump variables and patellar and Achilles tendons' structure in athletes and non-athletes. The main research questions are: Does the structure of the patellar and Achilles tendons relate to the temporal, kinetic, and kinematic jump variables? Does the relationship between these variables differ between athletes and non-athletes? To answer these questions, researchers will compare the two groups to determine if the relationships between the variables are similar. Participants will undergo a UTC (Ultrasound Tissue Characterization) scan of the patellar and Achilles tendons and perform five jumps: a countermovement jump, a single-leg countermovement jump on each leg and a single-leg horizontal jump on each leg.
