Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu
Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu
Theses: Doctorates and Masters
Previous studies on change of direction (COD) have reported that braking is an important factor for COD performance. However, previous studies have focused on the plant step and the penultimate step (PEN), thus little is known about deceleration before these steps. This study compared ground reaction forces (GRF) of two braking steps, the PEN and the step prior to PEN (PEN-1), the entry and exit velocity of the COD, and muscle function measures (leg press and leg curl one-repetition maximum, isometric and isokinetic strength, and drop jump performance) between faster and slower participants for a 90o sidestep cut.
