Trampolining terms are used to describe various positions and types of skill performed in the sport of trampolining. Basic skills Straight Jump – A vertical jump with the body held straight and arms in a straight line above the body at take-off. Tuck Jump – From a straight jump start, the knees are pulled up to the chest and the hands must at least briefly grasp the legs between the knees and ankle. Pike Jump – Again from a straight jump start, the legs are straight, held together and lifted parallel to the trampoline and the arms and body reach forwards towards the pointed toes. Straddle Jump – Similar to the pike jump except that the legs are spread sideways approximately 90° apart and the arms reach forward towards the pointed toes. Seat Drop or Seat Landing – Landing in a seated position with the legs straight. The hands support the body one either side and very slightly behind the posterior, palms down with fingers pointed towards the pointed toes. Seat Landing Half Twist to Seat Landing or Swivel Hips – Performing a seat landing, bounce up to a straight position (without landing) and then perform a half twist and land in the second seat landing facing in the opposite direction. Half Twist and Full Twist – While in a straight jump position rotating the body until facing the opposite direction for a half twist or a complete 360° rotation for a full twist. Stomach Drop, Front Drop or Front Landing – Landing horizontally on the bed, face down, with the arms bent to form a diamond shape with the hands overlapping slightly in front of the face. The legs should be bent slightly at the knee keeping the feet off the trampoline bed. But otherwise held in tension for a good landing. Back Drop or Back Landing – Landing on the bed on the back. The legs are bent up at about 90° on landing with legs held straight and the head is held in line with the body flat on the bed (to avoid whiplash injury). Hands and Knees 3/4 turnover – Bouncing on hands and knees then making a forward rotation to land in either Back Drop, to your feet or Seat Drop. Turntable – from front drop, bouncing, staying horizontal, performing a half twist around, then landing in front drop. Back drop half twist to back
