Change of direction (COD) total time is influenced by linear sprint ability and technique. Therefore, COD performance should be isolated from COD total time by measuring only the time taken to perform the COD and COD technique should be controlled. Current COD studies focus on the plant and penultimate (PEN) braking steps (Dos’ Santos et al, 2017, Jones et al, 2017), however, deceleration during a COD extends beyond these two steps (Nedergaard et al, 2014), thus, more braking steps ground reaction forces (GRF) needs to be examined. Cross sectional COD studies have shown that athletes with faster COD performance were …

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. This …
