The purpose of this study was to assess the sensitivity of wrist joint velocity to manipulations of knee joint flexion–extension kinematic waveforms through the use of a forward kinematic approach. The bowling kinematics of twelve male cricket pace bowlers were entered into a forward kinematic model using MATLAB software. The participants‘ knee joint flexion-extension kinematics were manipulated in two ways: 1) offset by ± 20° and 2) amplified by a factor of ± 2. Both manipulations led to increases in resultant wrist joint velocity at the time of ball release. An offset of 20° extension increased wrist joint velocity by 5.6% whereas an amplification factor of 2 increased wrist joint velocity by 29.9%. These results support the notion that a flexor-extender knee joint technique is ideal for cricket pace bowlers.
