The challenge involves stacking milk crates into a structure that resembles a podium, with both sides of the structure functioning as stairs. [1] The participant is expected to climb up to the top of the crates and climb back down without destroying the structure or falling, risking injury.
Falling down a flight of stairs or just a couple of steps is very common during infants’ first exposure to stair descent. Infants are more likely to fall down stairs than any other age group. [3] In the United States, approximately 73,000 children between the ages of 6 months and 2 years have reported injury on stairs or steps in 2009. [4]
"Each phase of the sequence included a 2-min warm-up, followed by 5 min of jumping. The four heights, measured by the distance the subjects’ feet were elevated above the trampoline bed, were 18, 37, 75, and 100 cm. A 5- to 10-min rest period was provided between each jumping level." The jump heights in inches were: 7", 14.6", 29.5" and 39.4".
The jumper faces the rope, jumps into the center (over the lower side), then across the higher side. She then repeats this action in reverse (jumping backward over the rope). This is repeated five times. Step 4: Rope in the position of Step 1—this time the action is performed with the jumper's hands, instead of her feet.
Running vertical jump: This refers to a vertical jump after a run up: the last step of the run is used to launch into the jump. This may help to add additional energy to the jump and improve on the standing vertical jump result. [2] In general, the standing vertical jump is the one that is used as an official measurement for athletes. [1]
In that routine, the Nicholas Brothers leapt exuberantly across the orchestra's music stands and danced on the top of a grand piano in a call and response act with the pianist, to the tune of "Jumpin' Jive". [3] Fred Astaire once told the brothers that this dance number was the greatest number he had ever seen on film. [14]
Trampolining or trampoline gymnastics [1] is a competitive Olympic sport in which athletes perform acrobatics while bouncing on a trampoline. [2] In competition, these can include simple jumps in the straight, pike, tuck, or straddle position to more complex combinations of forward and/or backward somersaults and twists.
The X/Spread Eagle jump is a beginner jump that involves the cheerleader putting their arms up into a V shape and jumping with their legs spread apart. When done correctly, the cheerleader's body will look like an X. This jump is generally used to practice group timing and quickly bringing legs together when coming down from a jump. [3]
