What is the newest Paralympic Winter sport as of 2014?

Snowboarding is indeed the newest Paralympic Winter sport as of 2014. It was officially included in the Paralympic program for the first time during the Sochi 2014 Winter Paralympics. This inclusion marked a significant expansion in the variety of sports available to athletes with disabilities, reflecting the growing recognition of snowboarding as a competitive sport in the Paralympics. Snowboarding events are designed to accommodate various classifications of athletes based on their physical abilities, allowing for a more inclusive approach to winter sports.

In contrast, biathlon, Nordic skiing, and adaptive skiing have been part of the Paralympic Winter Games for longer periods and are not considered recent additions. Therefore, snowboarding stands out as the latest sport introduced in that specific Paralympic Winter Games context.
