How did jousting contribute to the increasing weight of 15th-century armour?

During the 15th century, the weight of plate armour increased due to several factors, including the specific requirements of jousting.

Jousting was a form of mock combat where two knights, separated by a barrier, rode at each other to attempt to unseat their opponent using blunted lances. Because this activity involved high-impact, head-on collisions, it necessitated more complete and robust protection, which directly contributed to the heavier construction of armour during this period. This trend toward increased weight was further driven by the importance of shock tactics in European warfare, which demanded greater defensive coverage for the man-at-arms.1
