Snowboarding 

Snowboarding is a recreational activity and Olympic and Paralympic sport that involves descending a snow-covered slope while standing on a snowboardattached to a rider's feet.

The development of snowboarding was inspired by skateboarding, sledding, surfing and skiing. It was developed in the United States in the 1960s, became a Winter Olympic Sport at Nagano in 1998 and first featured in the Winter Paralympics at Sochi in 2014.

WaterSkiing 

Water skiing is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on two skis or one ski. The sport requires sufficient area on a smooth stretch of water, one or two skis, a tow boat with tow rope, three people (depending on state boating laws), and a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance.
