2.2.2.Reasons for the occurrence of an unreliable test
  • Different examiners are used for retesting, who use a slightly different protocol.
  • The examiner uses poor technique failing to standardize the test and calibrate equipment.
  • External factors have not been controlled, such as environmental conditions, order of tests or using different equipment for example.
  • Internal factors have not been controlled, such as when the athlete last ate/drank, the time of day or month the tests are performed at, fatigue levels and so on.
  • Use these important general guidelines as well, to standardize the testing procedure and ensure accuracy and reliability.
  • Always warm up thoroughly before performing physical fitness tests. Perform 5-10 minutes of light aerobic exercise followed by stretching to all the major muscle groups.
  • Complete short, explosive tests first. For example a standing vertical jump should be performed before a multistage shuttle run.
  • Always keep the order of the fitness tests the same when retesting.
  • Try to test at the same time of day and in similar environmental conditions.
  • Use the same equipment making sure it is properly calibrated before each testing session.
  • If an examiner is taking measurements, have the same person take the measurements each time. Needless to say they should be experienced in administering the tests.
  • Avoid eating within 3 hours of the test battery, and avoid smoking, coffee and alcohol on the day of the test.
  • Avoid training heavily the day before the physical fitness tests and do no training at all on the test day.
