The role of the internal rotation of the upper arm in javelin throwing

We performed a kinematic and inverse dynamic study with javelin throwers in order to assess the role of the internal rotation of the upper arm in javelin throwing and then compare the findings to baseball throwing. On the one hand, the results show an equal behaviour of the angular velocity, torque and power curves compared to baseball pitching. The evaluated peak values differ on the other hand. Hence, the different release velocities in baseball pitching and this study could serve as an explanation for the different values, which can vary enormously.
