The characteristics for grading ability of gripping, jumping, and throwing in later childhood

This study aimed to elucidate the characteristics for motor control ability of gripping, jumping, and throwing in late childhood. First, 10‒year‒old boys and girls were instructed to perform three movements, i.e., gripping, standing long jumping, and throwing with maximal effort (maximum task), and subsequently, with 50％ subjective effort (half task). Participants' force (gripping) and actual distances (jumping and throwing) were recorded and analyzed. The relative values of the half task were calculated based on the maximum task, and the constant and absolute errors from the target value (50％) were evaluated. We compared the movements (gripping, jumping, and throwing) and sex of the children (boys and girls).
