Weight of throwing implements used by youth athletes (i.e., children and juniors). Weight is displayed in kilograms except for the javelin (*), for which the units are grams. The weight of the throwing implements is shown as % MAX, meaning the percentage of the seniors’ equipment (i.e., weight of the children's implement/senior weight). A detailed overview of equipment used by youth in various countries appears in Table 3 below.
