Neuromuscular Changes in Drop Jumps on Different Common Material Surfaces with Incremental Drop Heights

The purpose of this study was to compare changes in muscle pre-activation and short-latency responses the lower limbs during drop jumps performed on different common soft hard surfaces at various platform heights. aimed collect electromyography data from rectus femoris, biceps tibialis anterior, gastrocnemius, soleus dominant leg sand, turf, polyurethane, wood heights 30, 40, 50, 60 cm. Muscle refers activity 100 ms before ground contact a jump, while refer activation occurring 30–60 after contact. These definitions were used measure analyze neuromuscular limb muscles using Sand as material 50 cm significantly enhanced (all p < 0.01). difficulty jump task can enhance latency muscles. It is recommended that athletes perform sandy or platforms higher than induce improve levels landing.
