Power is the time rate at which work is done or energy is transferred (Jones, no date). Hence, power is a mixture of both force and velocity (power= force x velocity).

Testing of Power – Vertical Jump test
- The Vertical Jump Test is used to test the power of an athlete. It is also known as the Sargent Jump Test and the Vertical Leap Test.
- This test is easily implemented with measuring tape, a wall and talc powder being the main equipment needed.
- Firstly, the athlete must stand beside the wall. They must reach up as high as they can with their arm and touch the wall with their fingers. This point is recorded and known as an athlete’s standing reach height.
- Then, the athlete must stand approximately half a metre away from a wall (facing the wall). He/she must use both their arms and their legs to leap into the air.
- At the highest point of their jump they must touch the wall with their fingers (which are covered in talc powder to leave a stain on the wall).
- The difference between the athlete’s standing reach height and jump height is the score.
