POWER: Power is “a combination of strength (force) and velocity or speed. Power is defined as work divided by time or the rate of doing work”, (Brian J. Sharkey, Steven E. Gaskill, and PG. 146 - 2007)
POWER = FORCE X DISTANCE / TIME
Test: The test that measures ones power is the Vertical Jump
Equipment:
1. Verti-Metric Vertical jump system. http://www.healthandcare.co.uk/strength/vertimetric-vertical-jump-assessment-system.html?gclid=CPed-tXrmb8CFQIYwwod7CEAxA
2. A mat is also required, “The Just Jump Mat is a 27 inch x 27 inch mat with a hand-held battery operated computer unit. The mat calculates vertical jump height by measuring the time that the feet are not in contact with the mat, and from this calculates explosive leg power”, (Just Jump System - Top end sport, 2014)

You can purchase the mat on: http://www.performbetter.com/webapp/wcs/stores/servlet/Product2_10151_10751_1004140_-1_1000198_1000194_1000194_ProductDisplayErrorView
Procedure:
1. The subject stands on the mat, with their feet slightly wider than shoulder width apart.
2. They then place their hands on their hips and stand tall.
3. When the administer has set up the equipment the subject can then jump when they want to.
4. They then jump over the mat and land.
5. The score is then read.
6. There is a minimal 15second recovery period between each jump performed.
7. The final result is best of 3.
The athlete will have two stances that are going to be measured. One stance will be in a squat position and then explode of the mat and the other stance will be from standing tall.

Advantages:
1. This test is far more accurate then the vertical wall jump test, as this test actually measures the time you’re in the air as soon as you leave the mat. This then provides you with results and you can predict your lower limb power.
2. Measures vertical leap and leg power.
3. Data can be stored and then analysed by using the device.
4. The apparatus is not large or bulky, so you can move it easily to suit the environment you are in.
5. Can be carried around and performed almost anywhere, preferably in a controlled environment such as a sports hall or lab.
6. The test does not take long to conduct.
Disadvantages:
1. The equipment is very expensive, http://www.healthandcare.co.uk/strength/vertimetric-vertical-jump-assessment-system.html?gclid=CPed-tXrmb8CFQIYwwod7CEAxA http://www.performbetter.com/webapp/wcs/stores/servlet/Product2_10151_10751_1004140_-1_1000198_1000194_1000194_ProductDisplayErrorView This will make it hard for many people to perform the test due to the price of the product. If athletes do want to perform the test they will have to go to a specialist lab that has the equipment.
2. To carry out the test, you need a specialist tester to administer the test.
3. The equipment required needs to be calibrated, this could prove to be difficult with some athletes if they are performing the test on their own. If they don’t calibrate the test and make sure the measuring box is correct then this could give them false results and affect future progressions and training programmes.
Validity:
This test does not take into consideration power in the arms it only focuses on power in the legs.
Reliability:To produce stable and consistent results the test should be performed in the same conditions, under the same administer.
