For example, when doing the sit and reach test, are you measuring hamstring flexibility only? For example body weight, body mass index (BMI), the beep test and jump tests all have normative data. Field testing is the key to detect the worthwhile and externally valid effects that are the focus of applied research [24, 25]. (see specific test preparation guidelines). Rather than common practices, research means and outcomes should guide the choice for the practitioner.

Cross your arms across your chest. Meaning that practitioners should be aware of the difference in precision that having an increase of 0.15 in CV induces.

These types of tests are more performance tests as often they are based on training responses or are more personive (that is without documented and researched protocols). Although it is outside the scope of this article, it is interesting to note that the test of significance is influenced by the amount of random variation between tests, conversely, ANOVA and T-tests assume, but are not very sensitive to, variations in normal distribution. Upon starting with a new team, practitioners need to determine the purpose of the testing (e.g. Med Sci Sports Exerc, 1995. Get started with the simple assessment below. 3.

Scoring (X), for example, vertical jump height, is comprised of the true score (T) and the error (e), and it can be expressed in the following equation [1]: Error is thought to originate in three main sources [2]: Error decreases the precision of a test and increases the smallest detectable change, making research and applied sport science less sensitive.
