The device used is known as a vertical jump tester. A vertical jump or vertical leap is the act of jumping upwards into the air. It can be an exercise for building both endurance and strength, and is also a standard test for measuring athletic performance. [1] It may also be referred to as a Sargent jump, named for Dudley Allen Sargent.
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances. If an object fell 10 000 m to Earth, then the results of both ...
Straddle technique. The straddle technique was the dominant style in the high jump before the development of the Fosbury Flop. It is a successor of the Western roll, [1] for which it is sometimes confused. Unlike the scissors or flop style of jump, where the jumper approaches the bar so as to take off from the outer foot, the straddle jumper ...
The jump ball was still used to start the game and every period, and to restart the game after a held ball.

Poles are manufactured for people of all skill levels and body sizes, with lengths between 3.05 m (10 ft 0 in) and 5.30 m (17 ft 5 in) and a wide range of weight ratings. Each manufacturer determines the weight rating for the pole and the location of the maximum handhold band. Speed is an essential element to high jumps.
"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 Axel jump is the most studied jump in figure skating. In competition, the base value of an Axel is determined by the number of revolutions completed during the jump. [7] The base value of a single Axel is 1.10, a double Axel 3.30, a triple Axel 8.00, a quadruple Axel 12.50 and a quintuple Axel is 14. [8]
Kobe Bryant shoots a fadeaway over Caron Butler. A fadeaway or fall-away in basketball is a jump shot taken while jumping backwards, away from the basket. The goal is to create space between the shooter and the defender, making the shot much harder to block. The shooter must have very good accuracy, much higher than when releasing a regular ...
