Test used: The 30M Sprint Test is used to measure ones speed.
EQUIPMENT:
Cones
Speed gates
Marked track
Flat and clear 50m surface
PROCEDURE:
1. The subject starts from a stationary position.
2. Their foot must be on or behind the starting line.
3. The subject must not be rocking or moving forwards before he has been told to start.
4. The athlete can begin the test as soon as the administrator has set up the time gates.
The 30m sprint begins as soon as the sensors on the speed gates are triggered. The test ends when they pass the finishing gates.

ADVANTAGES:
1. Using the speed gates is more reliable as you get an accurate score of your time for sprinting the 30 seconds.
2. The test doesn't take long to conduct.
3. The facilities required is another great advantage, as this test can be performed almost anywhere – the test needs to be conducted on a 50M flat surface.
4. The test is an overall good measurement of acceleration and speed, "The objective of this test is to monitor the development of the athlete's ability to effectively and efficiently build up acceleration, from a standing start or from starting blocks, to maximum speed", (Brian mac, 2014)
DISADVANTAGES:
1. The equipment that is required is expensive, you can purchase it here: http://www.habdirect.co.uk/brower-tc-gate?gclid=CJ6QzqqMn78CFa_LtAodE2sAig
2. The administrator of the test needs to know how to set up the specialist equipment.
Reliability:
The reliability of the test is enhanced if speed gates are used as they are far more precise than using a stop watch.
Using a crosswind would also increase the reliability when repeating the test, “If possible, set up the track with a crosswind to minimize the effect of wind”, (Topendsports, 2014)
Validity:
Precisely measures acceleration and speed. This test should be performed 3 times during 1 session to find an average score.
