List of extreme sports:
BASE Jumping: is very extreme activity that includes a parachute (can be used both parachute and wingsuit) to jump from fixed objects, with unopened parachute like skydiving. The acronym “B.A.S.E.” stands for: Building, Antenna, Span, Earth – four categories of objects from which B.A.S.E. jumper can jump.
Bodyboarding: is a kind of wave surfing. But instead of surfboard u have a rectangular piece of hydrodynamic foam.
Shape of board depends on riding style, and rider himself. Wiki says that bodyboarding is fastest growing extreme water sports all over the world.
Canoeing: extreme canoeing (a.k.a whitewater canoeing or whitewater racing). These extreme guys race specialised canoes and kayaks down a dangerous whitewater rivers. There is also such a class like Extreme Canoe racing, that includes much more complicated rapids, leave it for real pros :)
Extreme Motorsport: includes activities like supercross, motocross, freestyle motocross. Activities Travis Pastrana is good at 8)
Free Running: Parkour is all about efficient movement around obstacles, focussing on speed and fluidity going from A to B. Free running is a variation of parkour which focusses more on creativity of moves/tricks and self-expression. Both sports are done in an urban environment because there are lots of structures and obstacles to make use of.
Hangliding: - Gliding is either recreational or competitive and involves piloting an unpowered aircraft, using naturally occurring air currents to stay in the air. The gliders are launched into the air with either a powered aircraft or a winch.
Ice Climbing:
Kitesurfing:
Paragliding is where you hang from a canopy similar to a parachute and are launched from a hill, or from flat land using a winch. Slightly easier to fly and transport then hang gliders, paragliders however are more hampered by strong winds.
Rock Climbing:
Sand Boarding:
Sand Kiting:
Snowkiting:
Surfing:
Windsurfing:
White Water Rafting:
Wingsuit sky diving: Wingsuit diving is where someone wears a 'wingsuit' outfit whilst skydiving or base jumping so that they can glide through the air horizontally rather than mostly vertically. This helps the diver/jumper stay in the air longer and travel more distance. Skysurfing is where a board similar to a snowboard is strapped onto the skydivers feet.
